Understanding Nattable internal calls [message #1597644]

I have a combo box containing icons where user can chose an icon in a cell. When the user selects an icon, I paint it in the appropriate cell.

The problem is, that the image appears, but only momentarily and then some repaints from nattable causes the image to disappear. The question is, where to write my image painting code so that it displays correctly?

Thanks

If you want to show an image in a cell, you need to use the ImagePainter. Which image should be rendered depends on your configuration. Typically you need to register a label for the value you selected in the combobox and then register either an IStyle with the appropriate Image set, or register a specialized ImagePainter. I personally like the IStyle approach.
