Hallo, i implemented a custom editable comboBoxColumn in XamGrid according to the blog http://blogs.infragistics.com/blogs/devin_rader/archive/2010/07/08/creating-custom-columns-for-xamgrid.aspx by Devin Rader.in the provided solution, there is the ComboBoxColumn class together with the ComboBoxColumnContentProvider. I have made a little viewmodel hierachy where every row (every ComboBoxColumn) in the xamgrid has it's own viewmodel instance. As you can see when you run the application, everything is doing ok so far. After scrolling up and down the problem begins. Then the internal XamComboEditor somehow looses the binding for the selected item, when clicking on the ComboEditor cells. Refreshing the bindings in the overrided AdjustDisplayElement(Cell cell) works better, but still, if you scroll and click on a cell, often the selected item is gone. (when it is clicked a second time without scrolling before, the selected item is shown properly).Also what is irritating, the EmptyText is not shown in the the internal XamComboEditor.Is there another method to override? where should i refresh the bindings? Can you help me?Thanks in advanceThomas
Hello,
I am just checking if my last reply was helpful for you.
If you require any further assistance please do not hesitate to ask.
I have been looking into your issue and it seems that it is due to the virtualization of the XamGrid. By default there is no way to turn off it. I can suggest you look through the following link from our online community where it is provided a custom approach on how to turn off the virtualization :

i just realised, the EmptyText is not shown, because the ComboBox has Focus, of course. But the scrolling problem is still ugly.
