In reference to the ArrangeOverride method the documentation says:
The rectangle occupied by the element. Usually finalSize.
Should you return different size, the Layout system will restart
measuring and rearraning the items. That could lead to infinite
recursion.
I am occasionally seeing this. I have a grid that contains a single hierarchical child grid.
Type A
Type B
related on A.Foo, B.Foo
I don't know how to troubleshoot the root cause, but I can see that ArrangeOverride is being called in an infinite loop.
WTF?
Thanks.

Hi,
Recently, we had a similar problem with RadGridView, which entered infinite layout cycle. It was reproducible when UI Virtualization is disabled and row count is larger than ~150, but we fixed it as soon as it was reported. Can you please confirm which version you are using? If you experience this erroneous behavior even with the latest version, it will be great if you can send us a sample project to debug.

Thanks for the reply Ivan.
We're using:
Telerik UI for WPF
2014_1_0331
The scenarios I saw this occurring also seemed to depend on the number of rows being loaded, or perhaps more specifically whether or not those rows were causing the grid to vertically scroll off screen. I have a feeling that may have something to do with it.
I had the following property set on the gridview at the time:
EnableRowVirtualization="False"
and the grid was loading around 300 rows in the main grid, each having 1 child row in the hierarchical child grid.

Hi,
Could you please download the latest internal build and test with it (2014_1_0526)? The issue that I have mentioned was reproducible with similar parameters, so that I believe that things will work fine with this version.
