Column Header Image

[Xavier Soares]

Hello,

Is it possible to add an image to a Column Header instead of Text?

Many Thanks for your previous support/help.

Hi Luis,

Yes, it is possible. Here is some sample code how to achieve this:

GridTableHeaderRowElement header = (this.radGridView1.GridElement as GridTableElement).TableBodyElement.Children[0] as GridTableHeaderRowElement;

            this.radGridView1.ImageList = this.imageList1;

            foreach(RadElement element in header.Children )
            {
                if (element as GridHeaderCellElement != null)
                {
                    (element as GridHeaderCellElement).ImageIndex = 0;
                }
            }

1. I create a variable named header and initialize it with the header row element instance.
2. I set an imageList to the gridview which I will use to set images to the headers
3. I iterate through the header cell elements ( i.e column headers ) and then I set images.
4. To change the text of the columns you will have to set the Text property of the header cell elements, too.

If you have any questions please do not hesitate to write me.

Hi,

I'm sorry but the first line is to much for me! I using vb.net. Can you translate that code to VB.NET?

And in what event should I put that code?

Many Thanks, once more.

I'm also using VB.net, and your normally excellent code converter can't translate line 1 - maybe you can make these kinds of code (of which there are many in lots of your examples) a little bit simpler, then the code coverter can do it's work.

Maybe a useful step when answering ALL questions - make sure the code converter works on whatever code you sugest?

Hello, Ian,

If you are trying to convert the code snippet suggested from this reply, here is the same code snippet in VB:

Dim header As GridTableHeaderRowElement = TryCast((TryCast(Me.radGridView1.GridElement, GridTableElement)).TableBodyElement.Children(0), GridTableHeaderRowElement)
    Me.radGridView1.ImageList = Me.imageList1
    For Each element As RadElement In header.Children
        If TryCast(element, GridHeaderCellElement) IsNot Nothing Then
            (TryCast(element, GridHeaderCellElement)).ImageIndex = 0
        End If
    Next

Note, that Telerik Converter works fine when you convert methods instead of separate code snippets.

If you have any other questions please let me know.

Nadya
