I've been looking into the issue. This should be possible to do. I think
the key is going to be wiring-up the PreRender event for the
RadImageButton to set the ImageURL. You'll have to access the cell in
whichever RadControl you are using that contains the file name for the
image. I made an example using a RadGrid. The file name is in column 0,
and that file name is used to create the URL for the RadImageButton
which is in column 1 of the same row.
I hope this is clear - let me know if you have questions.
sender, EventArgs e)
RadButton btn = (sender
GridDataItem dataItem = btn.Parent.Parent
String filename = dataItem[
String fullPath =
btn.Image.ImageUrl = fullPath;
