as below i have code to display data,
it works very fine, while data available..
but it shows same data, if query doeent return any rows, it shows last loaded data,
even if query returns other data eventhough it shows last loaded data..
please help me out...
ReportDocument rptdoc = new ReportDocument();
Ds2 = new DataSet();
Ds2 = ClsPos.GetRejectedByPosition(int.Parse(Request.QueryString.Get("ID")));
string ReportName = Server.MapPath("RejectedCandidate.rpt");
rptdoc.Load(ReportName);
// Position Name
ParameterFields Parameters = new ParameterFields();
ParameterField idget = new ParameterField();
idget.Name = "PositionName";
ParameterDiscreteValue values = new ParameterDiscreteValue();
values.Value = Request.QueryString.Get("PositionName");
idget.CurrentValues.Add(values);
Parameters.Add(idget);
CRViewer1.ParameterFieldInfo = Parameters;
rptdoc.SetDataSource(Ds2.Tables["GetValues"]);
CRViewer1.ReportSource = ReportName;
CRViewer1.DisplayGroupTree = false;
use rptDoc.Refresh(); after loading report. i.e.
rptdoc.Load(ReportName);
rptDoc.Refresh();

In my datagridview, I just want to show other fields such as ID,LastName,FirstName, and MiddleName and i dont want to show any fields but i want it to retrieve even it's hidden. But when i specify what i just want to show in my datagridview it causes runtime error.
this is my code to load the datagridview.
MysqlConn.Open()
Dim Query As String
Query = "select ID,LastName,FirstName,MiddleName from god.precord"
COMMAND = New MySqlCommand(Query, MysqlConn)
SDA.SelectCommand = COMMAND
SDA.Fill(dbDataSet)
bSource.DataSource = dbDataSet
DataGridView1.DataSource = bSource
SDA.Update(dbDataSet)
MysqlConn.Close()
Catch ex As Exception
MessageBox.Show(ex.Message)
Finally
MysqlConn.Dispose()
End Try
then this is my code for retrieve data into textboxes
Private Sub DataGridView1_CellContentClick(sender As System.Object, e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick
If e.RowIndex >= 0 Then
Dim row As DataGridViewRow
row = Me.DataGridView1.Rows(e.RowIndex)
txtid.Text = row.Cells("ID").Value.ToString
txtlastname.Text = row.Cells("LastName").Value.ToString
txtfirstname.Text = row.Cells("FirstName").Value.ToString
txtmiddlename.Text = row.Cells("MiddleName").Value.ToString
txtaddress.Text = row.Cells("Address").Value.ToString
txtcontactno.Text = row.Cells("ContactNo").Value.ToString
txtgender.Text = row.Cells("Gender").Value.ToString
dtpbirthdate.Text = row.Cells("Birthdate").Value.ToString
txtage.Text = row.Cells("Age").Value.ToString
End If
End Sub
runtime error
please help me this is for my thesis
thankyou in advance <3
You have to add hidden column into the select query to retreive the data.
Hide the column from the DataGridView instead.
try
MysqlConn.Open()
Dim Query As String
Query = "select ID,LastName,FirstName,MiddleName,Address from god.precord"
COMMAND = New MySqlCommand(Query, MysqlConn)
SDA.SelectCommand = COMMAND
SDA.Fill(dbDataSet)
bSource.DataSource = dbDataSet
DataGridView1.DataSource = bSource
SDA.Update(dbDataSet)
DataGridView1.Columns("Address").Visible = false
MysqlConn.Close()
Catch ex As Exception
MessageBox.Show(ex.Message)
Finally
MysqlConn.Dispose()
End Try
i created a #Month as parameter name in crystal report and just insert to the report header section.
When i run the report always it asks the parameter by showing one box. How i pass through code. My existing code is below
MyReport rpt = new MyReport();
var srcData = ; //here i added my LINQ statement to select the data
rpt.SetDataSource(srcData);
ParameterDiscreteValue pdValue = new ParameterDiscreteValue();
pdValue.Value = combo2.SelectedValue;
rpt.ParameterFields["#Month"].CurrentValues.Add(pdValue);
this.ReportViewer1.ReportSource = rpt;
this.ReportViewer1.RefreshReport();
Where i did the mistake?
Hi I solved by just removing RefershReport() method of crystalreportviewer
I find from : http://www.it-sideways.com/2011/10/how-to-disable-parameter-prompt-for.html
If it's not working it suggests a typo or something. Try analyzing rpt.ParameterFields (set a breakpoint and watch). Have you got the parameter name correct? Data type?
I had trouble with adding parameters as well. Here's an example of what I got working:
string ponumber = Request.QueryString["ponumber"].ToString();
string receiptno = Request.QueryString["receiptno"].ToString();
// Put Away Report
CrystalReportSource CrystalReportSource1 = new CrystalReportSource();
CrystalReportViewer CrystalReportViewer1 = new CrystalReportViewer();
CrystalReportViewer1.ReportSource = CrystalReportSource1;
CrystalReportViewer1.EnableParameterPrompt = false;
CrystalReportSource1.Report.FileName = "Report3.rpt";
CrystalReportSource1.EnableCaching = false;
// This will set the values of my two parameters in the report
CrystalReportSource1.ReportDocument.SetParameterValue(0, ponumber);
CrystalReportSource1.ReportDocument.SetParameterValue(1, receiptno);
TableLogOnInfo logOnInfo = new TableLogOnInfo();
logOnInfo.ConnectionInfo.ServerName = ConfigurationManager.AppSettings["WarehouseReportServerName"];
logOnInfo.ConnectionInfo.DatabaseName = ConfigurationManager.AppSettings["WarehouseReportDatabaseName"];
logOnInfo.ConnectionInfo.UserID = ConfigurationManager.AppSettings["WarehouseReportUserID"];
logOnInfo.ConnectionInfo.Password = ConfigurationManager.AppSettings["WarehouseReportPassword"];
TableLogOnInfos infos = new TableLogOnInfos();
infos.Add(logOnInfo);
CrystalReportViewer1.LogOnInfo = infos;
maindiv.Controls.Add(CrystalReportSource1);
maindiv.Controls.Add(CrystalReportViewer1);
CrystalReportViewer1.DataBind();
I have a date range for a report from a selector. How can I print that range on the report header? I am inside a Crystal Report - not from code. I have a select expert using a IsBetween on a date field. The form prints everything fine. I just want to display the date range. I have tried the OnFirstRecord and OnLastRecord and WhilePrintingRecord to populate a string within a function - it just shows up as blank in the report.
// {#range}
// note case of format string
ToText(Minimum({?date_range}),"MM/dd/yyyy") + " - " + ToText(Maximum({?date_range}),"MM/dd/yyyy")
Add one or two Parameter in crystal report as per your requirement and then assign your date range to that parameters.
ParameterFields paramFields = new ParameterFields();
// ParameterDiscreteValue paramDiscreteValue = new ParameterDiscreteValue();
ParameterField paramField = new ParameterField();
ParameterDiscreteValue paramDiscreteValue = new ParameterDiscreteValue();
paramField.Name = "#Date1";
paramDiscreteValue.Value = TextBox1.Text.ToString();
paramField.CurrentValues.Add(paramDiscreteValue);
paramFields.Add(paramField);
paramField = new ParameterField(); // <-- This line is added
paramDiscreteValue = new ParameterDiscreteValue(); // <-- This line is added
paramField.Name = "#Date2";
paramDiscreteValue.Value = TextBox2.Text.ToString();
paramField.CurrentValues.Add(paramDiscreteValue);
paramFields.Add(paramField);
CrystalReportViewer1.ParameterFieldInfo = paramFields;
I found the NthSmallest and NthLargest functions - works perfectly now!
I have values in datasource and there is no problem with datasource. I have to assign X and Y values to the chart. Chart throws an error and says there is no column with named "TotalInboundArrivals".
ChartControl chart = new ChartControl();
chart.Location = new Point(38, 301);
chart.Size = new Size(789, 168);
Series series = new Series("Series1", ViewType.Bar);
chart.Series.Add(series);
series.DataSource = ds;
series.ArgumentScaleType = ScaleType.Numerical;
series.ArgumentDataMember = "TotalInboundArrivals"; //throws error here
series.ValueScaleType = ScaleType.Numerical;
series.ValueDataMembers.AddRange(new string[] { "StartTime" }); //throws error here
((SideBySideBarSeriesView)series.View).ColorEach = true;
((XYDiagram)chart.Diagram).AxisY.Visible = true;
chart.Legend.Visible = true;
chart.Visible = true;
chart.Dock = DockStyle.Fill;
xtraTabPage1.Controls.Add(chart);
Where is my Problem? Any Suggestions?
Have you went through Series.DataSource Property. You are making the mistake of assigning DataSet as DataSource to series. Think about it, how could it search columns in Data Source. Try to assign Ds.Tables["TableName"] as the datasource.
Creating DataSource Table
private DataTable CreateChartData(int rowCount) {
// Create an empty table.
DataTable table = new DataTable("Table1");
// Add two columns to the table.
table.Columns.Add("Argument", typeof(Int32));
table.Columns.Add("Value", typeof(Int32));
// Add data rows to the table.
Random rnd = new Random();
DataRow row = null;
for (int i = 0; i < rowCount; i++) {
row = table.NewRow();
row["Argument"] = i;
row["Value"] = rnd.Next(100);
table.Rows.Add(row);
}
Specifying Series properties corresponding to datasource
Series series = new Series("Series1", ViewType.Bar);
chart.Series.Add(series);
// Generate a data table and bind the series to it.
series.DataSource = CreateChartData(50);
// Specify data members to bind the series.
series.ArgumentScaleType = ScaleType.Numerical;
series.ArgumentDataMember = "Argument";
series.ValueScaleType = ScaleType.Numerical;
series.ValueDataMembers.AddRange(new string[] { "Value" });
Check the Examples and go through the Creating Charts -> Providing Data section to better understand it.
