set GridViewDataColumn width GridViewLengthUnitType.Star stop working in .2012.2.912.40 version

[Insight]

I want to set the column width to take the whole table sixe (fill) with the code below

gvColumn2.Width =

new GridViewLength(1, GridViewLengthUnitType.Star);

It worked fine with Telerik version 2012 Q1. However, it doesn't work when I installed  Telerik WPF v.2012.2.912.40.

Please suggest!
Thanks and regards

Hi,

 I've just tried this however everything worked as expected on our my end. You can check the attached project for more info.

It doesn't work in a particular case.
I can't attached the updated project here. Please use your project and copy the code below.
The gridview is created progammatically, it is nested in expander and within a tabitem of Tabcontrol. It works until the expander is placed within the Tabcontrol. Please review and suggest.

Hi,

I've reviewed your setup however I believe that this is not the proper way to work with ItemsControls and especially grids - definitely this worked incidentally with our Q2 version.

Have you noticed that RadGridView vertical scrollbar is missing? Your grid currently is measured with both infinity height and width and it is completely unusable. You cannot scroll it nor you can see the records outside of the initial viewport. 

I've attached the same example with standard WPF DataGrid for reference - you will get exactly the same result.

Dear Vlad,
Thank you for your response. However, I am not clear on your suggestion. The sample of standard WPF DataGrid you gave aslo have the same issue!
To make it's easier on attaching the reference code, I am opening a ticket for this issue.

Thanks again for your help.

Hello,

 What I'm trying to say is that your setup is not correct for both Telerik and standard WPF components.

Please revise your XAML!
