Unable to clear the table in RCP - swt

I am new in RCP. I have created one table and using TableEditor for some columns for putting Label and Progress bar.
But For some cases I want to clear the table. For textual content table.removeAll(); is working but its not clear the Label and Progress bar;
public void createPartControl(Composite parent) {
toolkit = new FormToolkit(parent.getDisplay());
compositeObj = toolkit.createComposite(parent, SWT.NONE);
GridLayout layout = new GridLayout();
compositeObj.setLayout(layout);
GridData gridData = new GridData();
gridData.verticalAlignment = GridData.FILL;
gridData.horizontalSpan = 4;
gridData.grabExcessHorizontalSpace = true;
gridData.grabExcessVerticalSpace = true;
gridData.horizontalAlignment = GridData.FILL;
myTable = new Table(compositeObj,
SWT.SINGLE | SWT.H_SCROLL | SWT.V_SCROLL | SWT.FULL_SELECTION | SWT.BORDER | SWT.CHECK);
myTable .setLayoutData(gridData);
final int[] bounds = { 30, 80, 100, 80, 100, 50, 100, 50, 50, 70, 50, 50 };
for (int i = 0; i < titles.length; i++) {
TableColumn tblColumn = new TableColumn(btsTable, SWT.NONE);
tblColumn.setText(titles[i]);
tblColumn.setWidth(bounds[i]);
tblColumn.setResizable(true);
tblColumn.setMoveable(true);
tblColumn.pack();
}
myTable.setHeaderVisible(true);
myTable.setLinesVisible(true);
for (int i = 0; i < receiverViewDataProvider.size(); i++) {
items[i] = new TableItem(btsTable, SWT.NONE);
}
fillData();
}
Table Filling Method
{
items[cntIndex].setText(1, sID);
items[cntIndex].setText(2, sName);
editor[cntIndex] = new TableEditor(myTable);
signalStrengthLabel1[selCnt] = toolkit.createLabel(myTable, sText, SWT.CENTER);
editor[cntIndex].grabHorizontal = true;
if (bIsAllow == true)
editor[cntIndex].setEditor(nameLabel1[selCnt], items[cntIndex], 3);
editor[cntIndex] = new TableEditor(myTable);
pbReverse[selCnt] = new ProgressBar(myTable, SWT.HORIZONTAL);
pbReverse[selCnt].setMinimum(0);
pbReverse[selCnt].setMaximum(30);
signalStrengthLabel1[selCnt].setText("" + iLevel + "");
pbReverse[selCnt].setSelection(iLevel);
editor[cntIndex].grabHorizontal = editor[cntIndex].grabVertical = true;
if (bAllow == true)
editor[cntIndex].setEditor(pbReverse[selCnt], items[cntIndex], 4);
}
Tried
for (int Index = 0; Index < Cnt; Index++) {
nameLabel1[btsIndex].setText("");
pbReverse[selIndex].setMaximum(0);
pbReverse[Index].setVisible(false);
editor[Index].dispose();
}
myTable.removeAll();
I am getting below result but want to clear the whole table

Hundred thousands of datatable records to PDF in web API

I'm trying to create PDF from the DataTable in web api using ADO.Net. Unfortunately based on filters some times I may get very less records & able to download without any problem. Sometimes may be very huge like 200 thousand of records. When I'm checking in local my system its getting hang while converting the dt to PDF. My code is like below:
private FileContentResult ExportPDF(DataTable dataTable)
{
string Name = "Logs";
System.IO.MemoryStream mStream = new System.IO.MemoryStream();
byte[] content = null;
try
{
string[] columnNames = (from dc in dataTable.Columns.Cast<DataColumn>() select dc.ColumnName).ToArray();
int count = columnNames.Length;
object[] array = new object[count];
dataTable.Rows.Add(array);
Document pdfDoc = new Document(PageSize.A2, 10f, 10f, 10f, 0f);
PdfWriter writer = PdfWriter.GetInstance(pdfDoc, mStream);
int cols = dataTable.Columns.Count;
int rows = dataTable.Rows.Count;
HeaderFooter header = new HeaderFooter(new Phrase(Name), false);
// Remove the border that is set by default
header.Border = iTextSharp.text.Rectangle.TITLE;
// Align the text: 0 is left, 1 center and 2 right.
header.Alignment = Element.ALIGN_CENTER;
pdfDoc.Header = header;
// Header.
pdfDoc.Open();
iTextSharp.text.Table pdfTable = new iTextSharp.text.Table(cols, rows);
pdfTable.BorderWidth = 1; pdfTable.Width = 100;
pdfTable.Padding = 1; pdfTable.Spacing = 4;

chunkCols = new Chunk(dataTable.Columns[i].ColumnName, ColFont);
cellCols.Add(chunkCols);
pdfTable.AddCell(cellCols);
}
//creating table data (actual result)
for (int k = 0; k < rows; k++)
{
for (int j = 0; j < cols; j++)

How to add buttons to a grid WP8.1 MVVM Light?

I'm having trouble building a dashboard in WP8.1.
I'm using the MVVM Light toolkit.
I'm looking after this outcome:
screenshot of dashboard
I can currently build a dashboard but only with one object per row.
I've searched a lot but haven't found anything to get the desired effect.
Here's the code of the dashboard done programatically:
int i = 0;
Grid grid = new Grid();
grid.RowDefinitions.Add(new RowDefinition());
for (int ct = 0; ct < 3; ct++)
grid.ColumnDefinitions.Add(new ColumnDefinition());
StackPanel stackPanel = new StackPanel();
stackPanel.Name = "stackPanel";
stackPanel.Background = new SolidColorBrush(new Windows.UI.Color());
foreach (var flow in dashboard.DashboardFlows)
{
if (flow.Flow.IsInstalled)
{
//if next object should change line
if (i == 3)
{
stackPanel.Children.Add(grid);
grid = new Grid();
grid.RowDefinitions.Add(new RowDefinition());
for (int ct = 0; ct < 3; ct++)
grid.ColumnDefinitions.Add(new ColumnDefinition());
i = 0;
}
Button button = new Button();
if (flow.Flow.Type.Equals("COMPNEWS"))
{
button.Click += delegate { Frame.Navigate(typeof(NewsPage), flow); };
}
//button stackpanel
StackPanel stack = new StackPanel();
//Button image
Image buttonImage = new Image();
if (!String.IsNullOrEmpty(flow.Flow.IconUrl) || !String.IsNullOrWhiteSpace(flow.Flow.IconUrl))
buttonImage.Source = new BitmapImage(new Uri(flow.Flow.IconUrl));
buttonImage.Height = 45;
buttonImage.VerticalAlignment = VerticalAlignment.Top;
stack.Children.Add(buttonImage);
//Button name
TextBlock buttonName = new TextBlock();
buttonName.Text = flow.Flow.Name;
buttonName.FontSize = 12;
buttonName.TextWrapping = TextWrapping.Wrap;
stack.Children.Add(buttonName);
button.Content = stack;
button.Margin = new Thickness(5, 0, 5, 0);
button.SetValue(Grid.ColumnProperty, i);
button.SetValue(Grid.RowProperty, 0);
button.HorizontalAlignment = HorizontalAlignment.Stretch;
button.VerticalAlignment = VerticalAlignment.Stretch;
button.Background = new SolidColorBrush(Color.FromArgb(130, 30, 30, 30));
grid.Children.Add(button);
i++;
}
}
scroll.Content = stackPanel;
Thank you in advance.

problems with rowspan while generating a PDF using iText

Below is my sample application where I am getting an error on line
Add2CellRow(table, "Age", 1, "Gender", 2);

how to insert table for existing form fill pdf using itextsharp

I have a form fill pdf where we dynamically add text field values to pdf. after adding this i need to add the table in the same page of the pdf.
if i add table it creates new pdf with only table. all other existing data are cleared.
I am using below code :
private void AddTableToPDF()
{
Document doc = new Document(iTextSharp.text.PageSize.LETTER, 10, 10, 100, 100);
try
{
string pdfFilePath = #"D:\Temp\PDF\Inspection Form - Steel Girder.pdf";
PdfWriter wri = PdfWriter.GetInstance(doc, new FileStream(pdfFilePath, FileMode.Append));
doc.Open();//Open Document to write
System.IO.MemoryStream mStream = new System.IO.MemoryStream();
PdfWriter writer = PdfWriter.GetInstance(doc, mStream);
DataTable dt = GetDataTable();
DataTable dtHeader = new DataTable();
dtHeader = GetHeaderDataTable();
if (dtHeader != null)
{
PdfPTable PdfTable = new PdfPTable(dtHeader.Columns.Count);
PdfPCell PdfPCell = null;
for (int rows = 0; rows < dtHeader.Rows.Count; rows++)
{
for (int column = 0; column < dtHeader.Columns.Count; column++)
{
PdfPCell = new PdfPCell(new Phrase(new Chunk(dtHeader.Rows[rows][column].ToString(), font8)));
PdfTable.AddCell(PdfPCell);
}
}
doc.Add(PdfTable); // add pdf table to the document
}
if (dt != null)
{
PdfPTable PdfTable = new PdfPTable(dt.Columns.Count);
PdfPCell PdfPCell = null;
PdfPCell = new PdfPCell(new Phrase(new Chunk("Reference", font8)));
PdfTable.AddCell(PdfPCell);
PdfPCell = new PdfPCell(new Phrase(new Chunk("Remark", font8)));
PdfTable.AddCell(PdfPCell);
PdfPCell = new PdfPCell(new Phrase(new Chunk("Description", font8)));
PdfTable.AddCell(PdfPCell);
for (int rows = 0; rows < dt.Rows.Count; rows++)
{
for (int column = 0; column < dt.Columns.Count; column++)
{
PdfPCell = new PdfPCell(new Phrase(new Chunk(dt.Rows[rows][column].ToString(), font8)));
PdfTable.AddCell(PdfPCell);
}
}
doc.Add(PdfTable); // add pdf table to the document
}
}
catch (DocumentException docEx)
{
Response.Write(docEx.Message);
}
catch (IOException ioEx)
{
Response.Write(ioEx.Message);
}
catch (Exception ex)
{
Response.Write(ex.Message);
}
finally
{
doc.Close();
}
}
Suppose your main PDF is named with m1.pdf. you just create a new PDF with name m2.pdf which will contain the new Table that you need to add. now just merge these Two PDF (m1.pdf & m2.pdf) in to new one 'MergedNerw.pdf')
To Merge Two PDF please use following code this Works fine i have Tested it:
protected void BtnMerge_Click(object sender, EventArgs e)
{
String[] files = #"d:\m1.pdf,d:\m2.pdf".Split(',');
MergeFiles(#"d:\MergedNew.pdf", files);
}
public void MergeFiles(string destinationFile, string[] sourceFiles)
{
if (System.IO.File.Exists(destinationFile))
System.IO.File.Delete(destinationFile);
string[] sSrcFile;
sSrcFile = new string[2];
string[] arr = new string[2];
for (int i = 0; i <= sourceFiles.Length - 1; i++)
{
if (sourceFiles[i] != null)
{
if (sourceFiles[i].Trim() != "")
arr[i] = sourceFiles[i].ToString();
}
}
if (arr != null)
{
sSrcFile = new string[2];
for (int ic = 0; ic <= arr.Length - 1; ic++)
{
sSrcFile[ic] = arr[ic].ToString();
}
}
try
{
int f = 0;
PdfReader reader = new PdfReader(sSrcFile[f]);
int n = reader.NumberOfPages;
//Response.Write("There are " + n + " pages in the original file.");
Document document = new Document(PageSize.A4);
PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(destinationFile, FileMode.Create));
document.Open();
PdfContentByte cb = writer.DirectContent;
PdfImportedPage page;
int rotation;
while (f < sSrcFile.Length)
{
int i = 0;
while (i < n)
{
i++;
document.SetPageSize(PageSize.A4);
document.NewPage();
page = writer.GetImportedPage(reader, i);
rotation = reader.GetPageRotation(i);
if (rotation == 90 || rotation == 270)
{
cb.AddTemplate(page, 0, -1f, 1f, 0, 0, reader.GetPageSizeWithRotation(i).Height);
}
else
{
cb.AddTemplate(page, 1f, 0, 0, 1f, 0, 0);
}
//Response.Write("\n Processed page " + i);
}
f++;
if (f < sSrcFile.Length)
{
reader = new iTextSharp.text.pdf.PdfReader(sSrcFile[f]);
//get the numnber of pages
n = reader.NumberOfPages;
//Response.Write("There are " + n + " pages in the original file.");
}
}
//Response.Write("Success");
document.Close();
}
catch (Exception e)
{
//Response.Write(e.Message);
}
}
Hope this helps you!

Align itextsharp table

Does anyone know how to left align a iTextSharp table?
You can use the PdfPTable's HorizontalAlignment property.
Here's a C# test method you can use to experiment:
private void TestTableCreation() {
using (FileStream fs = new FileStream("TableTest.pdf", FileMode.Create)) {
Document doc = new Document(PageSize.A4);
PdfWriter.GetInstance(doc, fs);
doc.Open();
PdfPTable table = new PdfPTable(4);
table.WidthPercentage = 50.0f;
// Options: Element.ALIGN_LEFT (or 0), Element.ALIGN_CENTER (1), Element.ALIGN_RIGHT (2).
table.HorizontalAlignment = Element.ALIGN_LEFT;
for (int i = 1; i <= 20; i++) {
PdfPCell cell = new PdfPCell(new Phrase(String.Format("Cell # {0}", i)));
cell.FixedHeight = 30.0f;
cell.HorizontalAlignment = Element.ALIGN_LEFT;
cell.VerticalAlignment = Element.ALIGN_MIDDLE;
table.AddCell(cell);
}
doc.Add(table);
doc.Close();
}
}
table.HorizontalAlignment = 1;
1:center
0:left
2:right
There are two ways of doing it:
cell.HorizontalAlignment = Element.ALIGN_LEFT;
cell.HorizontalAlignment = 0;
