Hi, 
I've been following the examples of this thread : http://www.telerik.com/community/forums/winforms/gridview/show-mulitple-images-in-a-gridview-column.aspx

This works fine, if the grid is painted only once. But if i scroll or change rows, the CreateCell event runs.
Also the scrolling make the buttons appear in cells that it should not appear in. I think this have something to do with the reuse of the cells in some way..

In my CreateCell i create an event for the button (like shown in the attached thread). BUt with the CreateCell going crazy all the time, this event is created a lot of times.. how can i avoid this?

Regards
SVein Thomas

Hello Svein,

Thank you for writing.

The described undesired behaviour is most probably a result of RadGridView UI virtualization. This means that RadGridView reuses its visual cell elements on scrolling, if they are compatible. To specify your custom cell should be used only for one specific column, you have to override IsCompatible method. More on this technique you can find in the following article in our product documentation: Creating custom cells.

All the best,
