How to hide header in PDF tables using C# and VB.NET?
Syncfusion Essential PDF is a .NET PDF library used to create, read, and edit PDF documents. Using this library, you can hide header in PDF tables using C# and VB.NET.
Steps to hide header in PDF tables programmatically:
- Create a new C# Windows Forms application project.
- Install the Syncfusion.Pdf.WinForms NuGet package as reference to your .NET Framework application from NuGet.org.
- Include the following namespaces in Form.cs file.
C#
using Syncfusion.Pdf; using Syncfusion.Pdf.Grid; using System.Drawing;
VB.NET
Imports Syncfusion.Pdf Imports Syncfusion.Pdf.Grid Imports System.Drawing
- Use the following code snippet to hide header in PDF tables.
C#
int count;
private void button1_Click(object sender, EventArgs e)
{
//Initialize count to 0
count = 0;
//Create a new PDF document
PdfDocument document = new PdfDocument();
//Add a page
PdfPage page = document.Pages.Add();
//Create a PdfGrid
PdfGrid pdfGrid = new PdfGrid();
//Create a DataTable
DataTable dataTable = new DataTable();
//Add columns to the DataTable
dataTable.Columns.Add("ID");
dataTable.Columns.Add("Name");
//Add rows to the DataTable
dataTable.Rows.Add(new object[] { "E01", "Mark" });
dataTable.Rows.Add(new object[] { "E02", "Chad" });
//Assign data source
pdfGrid.DataSource = dataTable;
pdfGrid.BeginCellLayout += PdfGrid_BeginCellLayout;
//Draw grid to the page of PDF document
pdfGrid.Draw(page, new PointF(10, 10));
//Save and close the document
document.Save("HideHeaderInPDFTables.pdf");
document.Close(true);
}
private void PdfGrid_BeginCellLayout(object sender, PdfGridBeginCellLayoutEventArgs args)
{
count++;
PdfGrid grid = (sender as PdfGrid);
if (count <= grid.Headers.Count * grid.Columns.Count)
{
args.Skip = true;
}
}
VB.NET
Private count As Integer
Sub Button1_Click(sender As Object, e As System.EventArgs) Handles Button1.Click
'Initialize count to 0
count = 0
'Create a new PDF document
Dim document As PdfDocument = New PdfDocument()
'Add a page
Dim page As PdfPage = document.Pages.Add()
'Create a PdfGrid
Dim pdfGrid As PdfGrid = New PdfGrid()
'Create a DataTable
Dim dataTable As DataTable = New DataTable()
'Add columns to the DataTable
dataTable.Columns.Add("ID")
dataTable.Columns.Add("Name")
'Add rows to the DataTable
dataTable.Rows.Add(New Object() {"E01", "Mark"})
dataTable.Rows.Add(New Object() {"E02", "Chad"})
'Assign data source
pdfGrid.DataSource = dataTable
AddHandler pdfGrid.BeginCellLayout, New PdfGridBeginCellLayoutEventHandler(AddressOf PdfGrid_BeginCellLayout)
'Draw grid to the page of PDF document
pdfGrid.Draw(page, New PointF(10, 10))
'Save and close the document
document.Save("HideHeaderInPDFTables.pdf")
document.Close(True)
End Sub
'BeginCellLayout event to hide headers
Private Sub PdfGrid_BeginCellLayout(ByVal sender As Object, ByVal args As PdfGridBeginCellLayoutEventArgs)
count += 1
Dim grid As PdfGrid = (TryCast(sender, PdfGrid))
If count <= grid.Headers.Count * grid.Columns.Count Then
args.Skip = True
End If
End Sub
