I have a crystal report which gives me undefined error when opening document, does any one come across this type of error, below is the coding:
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
///create instance of class first
ReportDocument rpDoc = new ReportDocument();
///load the report
rpDoc.Load(#"TicketingBasic.rpt");////------->>>problem is here
///pass the report to method for dataInfo
getDBInfo(rpDoc);
/// et the source for report to be displayed
CrystalReportViewer1.ReportSource = rpDoc;
}
protected static void getDBInfo(ReportDocument rpDoc)
{
///Connection Onject
ConnectionInfo cn = new ConnectionInfo();
///DataBase,Table, and Table Logon Info
Database db;
Tables tbl;
TableLogOnInfo tblLOI;
///Connection Declaration
cn.ServerName = "???????????";
cn.DatabaseName = "??????????";
cn.UserID = "?????????";
cn.Password = "????????????";
//table info getting from report
db = rpDoc.Database;
tbl = db.Tables;
///for loop for all tables to be applied the connection info to
foreach (Table table in tbl)
{
tblLOI = table.LogOnInfo;
tblLOI.ConnectionInfo = cn;
table.ApplyLogOnInfo(tblLOI);
table.Location = "DBO." + table.Location.Substring(table.Location.LastIndexOf(".") + 1);
}
db.Dispose();
tbl.Dispose();
}
}
Final code snippet is:
rpDoc.Load(Server.MapPath(#"TicketingBasic.rpt"));
Thank you all for the help.
The problem I am having now is report not printing or exporting to other types like .pdf,.xsl, .doc etc, any clue
so the error is literally "undefined error"? never seen that one before.
First guess is that you need the full physical path to the report.
rpDoc.Load(Server.MapPath(#"TicketingBasic.rpt"));
HttpServerUtility.MapPath
How are you handling the report outout?
When we do reports we set the file name:
ReportSource.Report.FileName = FileName;
Where filename is a string that is the name of the file (obviously). Then we select the report tables and export in whatever format. Try this.

I have created a record-view form that contains a few bound elements via a BindingSource and a BindingNavigator. The viewing of the data fields is operating correctly. Note that the variables da and ds are global in this form.
private void frmItem_Load(object sender, EventArgs e) {
string scon = System.Configuration.ConfigurationManager.ConnectionStrings["myitems"].ToString();
da = new SqlDataAdapter("Select * From myitems where id > 0 ", scon);
ds = new DataSet();
da.Fill(ds);
bindingSource1.DataSource = ds.Tables[0];
bindingNavigator1.BindingSource = this.bindingSource1;
this.txtId.DataBindings.Add(new Binding("Text", bindingSource1, "id", true));
this.txtItem.DataBindings.Add(new Binding("Text", bindingSource1, "item", true));
this.txtUpdatedwhen.DataBindings.Add(new Binding("Text", bindingSource1, "updatedwhen", true));
}
I am showing this record-view form from a data grid view of items by using a row header mouse dbl-click event. The requested row from the dgv is correctly being selected and its row data is correctly being shown in the record-view form.
private void dgvItems_RowHeaderMouseDoubleClick(object sender, DataGridViewCellMouseEventArgs e) {
frmItem gfrmItem = new frmItem();
string sID = this.dgvItems.CurrentRow.Cells[0].Value.ToString();
gfrmItem.FilterByID(sID);
gfrmItem.Show();
}
I've added a save button to the navigator so that I can make individual record save. What I'm attempting to do is programatically apply a date/time stamp update before the record is saved from the button click.
private void btnSave_Click(object sender, EventArgs e)
{
this.txtUpdatedwhen.Text = DateTime.Now.ToString();
da.Update(ds);
}
Although the date/time value is changed per the code and shows in the form, the update is not applying the date/time change.
I thought that the textbox value was being bound to the underlying dataset and would accept changes as if I had entered it manually ... but this is not occurring. I had read some other posts that using the data adapter update is the right way to go about this as apposed to doing something like performing a direct sql update.
I'm stumped with how to resolve this. Any pointers would be greatly appreciated.
After letting this sit a while and coming back to it today, I found a resolution.
There was a common misunderstanding at work that I saw in other posts.
That was that the dataadapter does not automatically populate its commands, even if you pass an active connection into the creation step.
So my resolution was to create a global SqlCommandBuilder variable along with the other ones I was using
SqlDataAdapter da;
SqlConnection sc;
SqlCommandBuilder sb;
DataSet ds;
then create the builder object at form load and initialize the update command into a string variable ... which isn't used there after, but the dataadapter commands are now populated.
string scon = System.Configuration.ConfigurationManager.ConnectionStrings["networkadmin"].ToString();
sc = new SqlConnection(scon);
sc.Open();
string sSelect = "Select * From datatable where id > 0 Order By fld1;";
}
this.da = new SqlDataAdapter(sSelect, sc);
sb = new SqlCommandBuilder(da);
// This initiates the commands, though the target var is not used again.
string uCmd = sb.GetUpdateCommand().ToString();
this.ds = new DataSet();
this.da.Fill(this.ds);
Then the update step does work as expected:
this.txtUpdatedwhen.Text = DateTime.Now.ToString();
DataRowView current = (DataRowView)bindingSource1.Current;
current["updatedwhen"] = this.txtUpdatedwhen.Text;
bindingSource1.EndEdit();
this.da.Update(ds);
I hope this helps someone.
I have made two queries in dataset, then I want to set that query to the report
the first query is for the main report,
and the second query is for the subreport which have show by one of attribute field in main report.
Like I will show data (with where : from attribute field from main report)
Please anyone help me...
^^ but this code is still wrong
ReportDocument RptDocument = new ReportDocument();
protected void Page_Load(object sender, EventArgs e)
{
DataSet ds = "Your Dataset";
CrystalReportViewer1.DisplayGroupTree = false;
ds.Tables[0].TableName = "Main Report";
RptDocument.Load(Server.MapPath("your rpt file path"));
RptDocument.SetDataSource(ds.Table[0]);
RptDocument.Subreports[0].SetDataSource(ds.Tables[1]);
CrystalReportViewer1.ReportSource = RptDocument;
CrystalReportViewer1.DataBind();
CrystalReportViewer1.Visible = true;
}
please refer this code
I'm developing a jrxml template for generate job candidate's resume. The candidates are in my database.
I need to generate a Word file (.docx) for 1 record (by job candidate), as the image below:
How can I make Jasper generate one file for each record of my SQL query? And export these files to Word?
I saw there is a parameter called PAGE_INDEX exporter. But I did not find how to use it ...
Can someone help me please?
Note 1: My reports are not generated by JasperServer. I developed a Java program to generate them and send reports by email.
Note 2: The number of pages for each candidate may be different.
Updating status
I managed to generate one record per file. But I could only generate the file to the first record.
I need to generate other files for the remaining records.
I'm still with the another problem too: how to separate into separate files when the number of pages for each record (candidate entity) can change?
final JRDocxExporter exporter = new JRDocxExporter();
exporter.setExporterInput(new SimpleExporterInput(jasperPrint));
exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(new java.io.File("/home/admin/resume candidate.docx")));
SimpleDocxReportConfiguration configuration = new SimpleDocxReportConfiguration();
configuration.setPageIndex(0);
exporter.setConfiguration(configuration);
exporter.exportReport();
PROBLEM SOLUTION
I solved the problem by inserting a variable in the footer of each page with the expression: $V{REPORT_COUNT}, which have record count that is in the Detail Band:
After that, the Java program do loop between the pages of JasperPrint object.
So, i locate that element that tells me what page belongs to candidate.
Based on this information and storing candidate index data and its pages (in a HashMap > mapCandPage), I can determine the page that starts and the page ends for each candidate. And that way I can export one document for each candidate record.
public static void main(String args[]) throws Exception {
File relJasperArqFile = new File("Candidate Resume Template.jasper");
Connection conn = ConnectionFactory.getNewConnectionSQLDRIVER();
JasperReport jasperReport = (JasperReport) JRLoader.loadObject(relJasperArqFile);
JasperPrint jasperPrint
= JasperFillManager.fillReport(jasperReport,
null,
conn);
final JRDocxExporter exporter = new JRDocxExporter();
exporter.setExporterInput(new SimpleExporterInput(jasperPrint));
List<JRPrintPage> listPrintPage = jasperPrint.getPages();
int candIdx = 0;
int fileIdx = 0;
int lastCandIdx = 0;
HashMap<Integer, List<Integer>> mapCandPage = new HashMap<>();
for (int pageIdx = 0; pageIdx < listPrintPage.size(); pageIdx++) {
JRPrintPage page = listPrintPage.get(pageIdx);
candIdx = getCandIdx(page);
if (!mapCandPage.containsKey(candIdx)) {
mapCandPage.put(candIdx, (new ArrayList<>()));
}
mapCandPage.get(candIdx).add(pageIdx);
if (pageIdx > 0 && candIdx != lastCandIdx) {
fileIdx++;
exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(new File(String.format("Candidate Resume %d.docx", fileIdx))));
SimpleDocxReportConfiguration configuration = new SimpleDocxReportConfiguration();
configuration.setStartPageIndex(mapCandPage.get(lastCandIdx).get(0));
configuration.setEndPageIndex(mapCandPage.get(lastCandIdx).get(mapCandPage.get(lastCandIdx).size() - 1));
exporter.setConfiguration(configuration);
exporter.exportReport();
}
lastCandIdx = candIdx;
}
fileIdx++;
exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(new File(String.format("Candidate Resume %d.docx", fileIdx))));
SimpleDocxReportConfiguration configuration = new SimpleDocxReportConfiguration();
configuration.setStartPageIndex(mapCandPage.get(lastCandIdx).get(0));
configuration.setEndPageIndex(mapCandPage.get(lastCandIdx).get(mapCandPage.get(lastCandIdx).size() - 1));
exporter.setConfiguration(configuration);
exporter.exportReport();
}
public static Integer getCandIdx(JRPrintPage page) {
JRPrintElement lastRowNumber = page.getElements().get(page.getElements().size() - 1);
return Integer.parseInt(((JRTemplatePrintText) lastRowNumber).getFullText());
}
This is a test and my code is not optimized. If anyone has suggestions or a better idea, please post here. Thank you.
Is there a tool that will let you search a number of different crystal reports to see where a specific Table/View/SP is being used?
Scenario is this: We have over 200 reports, so when making a change to a View or Stored Procedure it is not easy to find which reports will be affected without opening each one and checking the "Database expert" or "Datasource location".
I have tried Agent Ransack on them and it doesn't pick any table or view names up.
I never found a tool to do this, so rolled my own in C# .Net 4.0.
If the crystal report uses a 'SQL Command' instead of dragging in tables, it becomes a bit tricky. I suggest only searching for the TableName rather than the fully qualified Database.dbo.TableName - since this may have been omitted in the pasted SQL Command.
usage:
var reports = CrystalExtensions.FindUsages("C:/Reports", "table_name");
code:
namespace Crystal.Helpers
{
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Reflection;
using CrystalDecisions.CrystalReports.Engine;
using Microsoft.CSharp.RuntimeBinder;
public static class CrystalExtensions
{
public static List<string> FindUsages(string directory, string tableName)
{
var result = new List<string>();
foreach (var file in Directory.EnumerateFiles(directory, "*.rpt", SearchOption.AllDirectories))
{
using (var report = new ReportClass { FileName = file })
{
if (report.Database == null) continue;
var tables = report.Database.Tables.ToList();
var hasTable = tables.Any(x => x.Name == tableName || x.GetCommandText().Contains(tableName));
if (hasTable)
result.Add(file);
}
}
return result;
}
public static List<Table> ToList(this Tables tables)
{
var list = new List<Table>();
var enumerator = tables.GetEnumerator();
while (enumerator.MoveNext())
list.Add((Table)enumerator.Current);
return list;
}
public static string GetCommandText(this Table table)
{
var propertyInfo = table.GetType().GetProperty("RasTable", BindingFlags.NonPublic | BindingFlags.Instance);
try
{
return ((dynamic)propertyInfo.GetValue(table, propertyInfo.GetIndexParameters())).CommandText;
}
catch (RuntimeBinderException)
{
return ""; // for simplicity of code above, really should return null
}
}
}
}
Hope that helps!
See the question here:
Any way to search inside a Crystal Report
Another option is to roll-your-own piece of software to do it, but that might be more time consuming than you're looking for. Or, find someone who already has done this :) If you find something that works, let the rest of us know because we're all in the same boat. Good luck!
i have an app which has btn to preview report made in crystal report. I added Dataset as datasource of the report and dragged datatable from the toolbox and added the fields I need as columns. I got the instruction from this link http://aspalliance.com/2049_Use_LINQ_to_Retrieve_Data_for_Your_Crystal_Reports.2. This is my 2nd report the first one works and did not encounter any prob at all that is why i am confused, not to mention it also has nullable column. the error says: DataSet does not support System.Nullable<>.
private void ShowReportView()
{
string reportFile = "JudgeInfoFMReport.rpt";
ObservableCollection<tblJudgeFileMaint> judgeFileMaintList;
judgeFileMaintList = GenerateReport();
if (judgeFileMaintList.Count > 0)
{
CrystalReportViewerUC crview2 = new CrystalReportViewerUC();
crview2.SetReportPathFile(reportFile, judgeFileMaintList);
crview2.ShowDialog();
}
else
{
System.Windows.MessageBox.Show("No record found.", module, MessageBoxButton.OK, MessageBoxImage.Information);
}
}
private ObservableCollection<tblJudgeFileMaint> GenerateReport()
{
var result = FileMaintenanceBusiness.Instance.GetAllJudgeInfoList();
return new ObservableCollection<tblJudgeFileMaint>(result);
}
The error is in the part where I set datasource report.SetDataSource
public bool SetReportPathFile(string reportPathFile, IEnumerable enumerable)
{
string reportFolder = #"\CrystalReportViewer\Reports\";
string filename = System.Windows.Forms.Application.StartupPath + reportFolder + reportPathFile; // "\\Reports\\CrystalReports\\DateWiseEmployeeInfoReport.rpt";
ReportPathFile = filename;
report.Load(ReportPathFile);
report.SetDataSource(enumerable);
report.SetDatabaseLogon("sa", "admin007");
bRet = true;
}
_IsLoaded = bRet;
return bRet;
}
I read some answers and says I should set the null value to DBNUll which I did in the properties window of each column if it is nullable. Can anyone help me please? thanks
Your question can be seen in this post, but in a generic way ... that way you can pass an Object to a DataSet typed!
.NET - Convert Generic Collection to DataTable
figured it out. by using a collectionextention, copied somewhere, I forgot the link. Os to whoever it is who made the class, credits to you.
class method looks like this.
public statis class CollectionExtension {
public static DataSet ToDataSet<T>(this IEnumerable<T> collection, string dataTableName)
{
if (collection == null)
{
throw new ArgumentNullException("collection");
}
if (string.IsNullOrEmpty(dataTableName))
{
throw new ArgumentNullException("dataTableName");
}
DataSet data = new DataSet("NewDataSet");
data.Tables.Add(FillDataTable(dataTableName, collection));
return data;
}
}
then you can use it by doing this in getting your source to your report:
private DataSet GenerateNeutralContEducReport(string dsName)
{
var contEduHistoryList = FileMaintenanceBusiness.Instance.GetManyNeutralFMContEducHistoryInfobyKeyword(CurrentNeutralFM.NeutralID, "NeutralID").ToList();
return CollectionExtensions.ToDataSet<tblContinuingEducationHistory>(contEduHistoryList, dsName);
}
I found little help from the other proposed answers but this solution worked.
A different way to solve this problem is to make the data column nullable.
DataColumn column = new DataColumn("column", Type.GetType("System.Int32"));
column.AllowDBNull = true;
dataTable.Columns.Add(column);
https://learn.microsoft.com/en-us/dotnet/api/system.data.datacolumn.allowdbnull?view=netcore-3.1
foreach (PropertyDescriptor property in properties)
{
dt.Columns.Add(property.Name, Nullable.GetUnderlyingType(property.PropertyType) ?? property.PropertyType);
}
