Examples
The following example shows how to a TableLayoutCellPaintEventHandler delegate to customize the appearance of a TableLayoutPanel control. This code example is part of a larger example provided for the TableLayoutPanel control.
public class DemoTableLayoutPanel : TableLayoutPanel
{
protected override void OnCellPaint(TableLayoutCellPaintEventArgs e)
{
base.OnCellPaint(e);
Control c = this.GetControlFromPosition(e.Column, e.Row);
if ( c != null )
{
Graphics g = e.Graphics;
g.DrawRectangle(
Pens.Red,
e.CellBounds.Location.X+1,
e.CellBounds.Location.Y + 1,
e.CellBounds.Width - 2, e.CellBounds.Height - 2);
g.FillRectangle(
Brushes.Blue,
e.CellBounds.Location.X + 1,
e.CellBounds.Location.Y + 1,
e.CellBounds.Width - 2,
e.CellBounds.Height - 2);
};
}
}
Public Class DemoTableLayoutPanel
Inherits TableLayoutPanel
Protected Overrides Sub OnCellPaint( _
ByVal e As System.Windows.Forms.TableLayoutCellPaintEventArgs)
MyBase.OnCellPaint(e)
Dim c As Control = Me.GetControlFromPosition(e.Column, e.Row)
If c IsNot Nothing Then
Dim g As Graphics = e.Graphics
g.DrawRectangle( _
Pens.Red, _
e.CellBounds.Location.X + 1, _
e.CellBounds.Location.Y + 1, _
e.CellBounds.Width - 2, _
e.CellBounds.Height - 2)
g.FillRectangle( _
Brushes.Blue, _
e.CellBounds.Location.X + 1, _
e.CellBounds.Location.Y + 1, _
e.CellBounds.Width - 2, _
e.CellBounds.Height - 2)
End If
End Sub
End Class
Remarks
When you create a TableLayoutCellPaintEventHandler delegate, you identify a method to handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event handler delegates, see Handling and Raising Events.
