GridView - contents of all columns get pushed into one column after filtering

[tomsky]

We have a fairly advanced RadGridView (custom columns + converters, child items, custom filters) which is used to display a large number of items (often in excess of 10000). The problem occurs when we apply filters (we then remove all items from the Collection that is bound to the grid) and then re-add those items that match the criteria of the new filter. The issue can only be observer when a very large number of items get added to the grid. Also, what's interesting is that most (90%) of the items are fine, the problem can only be seen when you scroll down. Please see the attached screenshot to better understand the problem.

Hello,

I believe that if this was a bug in RadGridView, it is fixed in our latest official release. Could you download it and give it a try?

Thanks for your reply. I'll certainly give a try updating telerik assemblies. While investigating this I also noticed some issues with our code which could be causing this issue.

 

Thanks
