[Solved] RadDataGrid - Layout Cycle Detected on Surface Pro Touch-Enabled Device

[Quake]

As soon as the RadDataGrid shows on this device, an exception occurs.  Very little info is provided but the top-level message is:
"Layout Cycle Detected Layout could not complete"

datetimecolumn.png = datetimecolumn.zip
Surface_Pro.png = Surface_Pro.zip

I tried attaching a sample project and the msinfo32 dump but the forum does not allow attachments of that format.  Let me know if I can help you track down this issue.

Thanks

Hello,

Could you please elaborate more on your scenario and also send us a code snippet? We have already fixed a bug that causes this exception(the fix will be included in our Q3 2013 BETA release) and the current problem may be related to this bug.

I am looking forward to your reply.

I've been banging my head against the issue for months but finally found the problem (as mentioned above all you see is an error "Layout cycle detected" and no stacktrace).

It happens when the grid is being resized, in my case caused by a resizable panel next to it which the user can expand/collapse with an animation.

If I have my datagrid columns created manually and not autogenerated I can set the DataGridColumn.SizeMode to Stretch which causes the problem. Setting this value to Fixed or Auto 'fixes' it although the behaviour isn't so nice as I want my grid to resize for all screen sizes.

Also the performance of Stretched columns when resizing the grid isn't very good and the animation looks choppy, so I guess there is too much being computed during layout changes.

Will there be a fix for this in the upcoming release? Thanks

Hi,

 

thx for this information, it saved a lot of time. I had the same problem on a Surface Pro 3 and only on this model. On one of the gridcolumns I had a combination of SizeMode="Stretch" and Width="400" set. Removing the Width on that column fixed the problem for me. This behavior is strange because it is limited to this model. Our app runs on other models (Surface RT/Surface 2 Pro/Surface 3) without any problems.

Hello guys,

Could you please strip some simple project which is proved to reproduce the exception?
