tile column header background images

[Mario]

I am working with a GridGroupingControl of the current version. The enclosed images show what I try to achieve and what I currently have.

How can I tile background images for column headers? GridBackgroundImageMode only allows me to stretch or center the image.

Thanks for your help.

Hi Mario,

There is no built-in support for this. You can use the TableControlDrawCell event to customize the images that appear in the ColumnHeader cell in a gris. Here is a code snippet:

GridTableCellStyleInfo info = e.Inner.Style as GridTableCellStyleInfo;
if( info.TableCellIdentity.TableCellType == GridTableCellType.ColumnHeaderCell )
{
e.Inner.Renderer.Draw(e.Inner.Graphics,e.Inner.Bounds,e.Inner.RowIndex,e.Inner.ColIndex,e.Inner.Style);
e.Inner.Cancel = true;
Image image = "Your Image: //////SystemIcons.Exclamation.ToBitmap();
TextureBrush tBrush = new TextureBrush(image);
Pen blackPen = new Pen(Color.Black);
e.Inner .Graphics.FillRectangle(tBrush, e.Inner.Bounds );
e.Inner.Graphics.DrawRectangle(blackPen, e.Inner.Bounds );
//If you want to show the Header Text cleary ..... try use the DrawString method.

}

Thanks
