Mouse Scrolling Crash for Gridview in new version 2011.1.419.1040

[Hrushikesh]

We are getting Issue when we scroll with the mouse on the Grid. if you do up and down with the mouse scroll it come. The Grid contains ROwDetail which again contain grid. Below is the structure of that  grid

<my:CustomDataGrid RowDetailsVisibilityMode="VisibleWhenSelected" telerik:StyleManager.Theme="Windows7" KeyUp="grdCasesReportList_KeyUp" KeyDown="grdCasesReportList_KeyDown" ShowGroupPanel="False" Loaded="OuterGrid_Loaded"

Hi,

 I were not able to reproduce the issue with our most recent version - Q3 2012 (2012.3.1017). May I ask you to test with that version?

Regards,
Didie

I updated to the latest telerik build today.
It is still occurring every time.

tip:
Put the grid in a small popup with less height( lets say 400) and width (400)
while u hover over the individual item, u will see the tooltip of each row. At that point, start scrolling with the mouse ball, don't scroll too slow.
it will crash every time.

[Anne Lyon]

Is there a solution to the problem mentioned above? I have a GridView with a TooltipTemplate for each GridViewDataColumn. If I scroll (using the mouse wheel) while the mousePointer is pointing at a column with a Tooltip, I get an error 4004 crash. If the mousePointer points somewhere without a tooltip everything is fine. Obviously scrolling while the Grid tries to show a tooltip does not combine.

Any workaround?

Thanks!

Hello Anne,

As this issue has already been fixed, can you please try updating to the latest assemblies version? If the issue is still reproducible, would it be possible for you to demonstrate it in a sample application and add it as attachment in a new support thread, so we can further investigate?

Thank you in advance for your cooperation.

All the best,
