DataGrid with long description hang when scrolling

[Cloud]

We have problems in scrolling datagrid with long description column. If the display value for a column is not too long, the scrolling is working properly. However if there is a long description shown in a column as shown in the attached screen, the screen will hang when scrolling in the datagrid and the WPF window cannot be recovered until closed and reopened. The no of records are not that large and are around 600 only. Below is the reference code. Please advice the solution.

Hi,

 Can you post more info about your grid version? We are not sure also why you've set ScrollViewer.HorizontalScrollBarVisibility and ScrollViewer.VerticalScrollBarVisibility for the grid. Can you clarify?

We are using RadControls version v.2011.2.920.35.
I have tried to remove the properties 'ScrollViewer.HorizontalScrollBarVisibility' and 'ScrollViewer.VerticalScrollBarVisibility' but it still doesn't work. But we found that if 'AutoGenerateColumns' property is not set, the grid will work properly when scrolling. However we indeed need to disable the autogeneration since extra columns are now generated and we do have some specific format for each column. So is there any solution to solve that?

Hello ,

 We are still not sure what's the exact problem at your end however you can customize auto-generated columns using AutoGeneratingColumn event. You can even cancel adding of some column(s).
