using version 2011 Q1
I have a window with a tree view and a grid
when I change the selected item in the tree i run query, build an ObservableCollection and bind it to the ItemSource of the grid.
all grid columns are Width="Auto"
the problem is that when i rebind the ItemSource, the width of columns don't update correctly, actually they don't update at all.
sometimes a column in the the resulting collection has 200 characters at most, other times 25 characters at most.
the columns width does not re size to correctly to 25 characters, it is left at 200 characters, the columns have too much white-space.
is the grid not supposed to do update the columns when the ItemSource gets a new collection?
if not how can I force the columns to adjust to current data collection.
as in one of your examples i have tried to iterate the grid.Columns setting the width to Auto, nothing happened.

your help would be much appreciated.
thanks

Hi,

 Can you try Q1 2011 SP1 instead? Later Today we will release our Q2 - if you want you can try it directly.

Updated to 2011 Q2 and the problem still exists.

I have created a sample application that has the same problem.

Sample Application

My current application is a WinForm application hosting the RadGridView.

thanks again.

Hello John,

Thank you for the sample application.
This is a know issue and it has been logged in our PITS system. You can track its progress by following ID1630.

This problem still exists in the RadControls for WPF Q3 2011 (Runtime Version v4.0.30319, Version 2011.3.1220.40).  I updated the SampleApplication and found the column widths did not change.

Hi Kevin,

The PITS issue with ID1630 has been resolved. It seems that the case in the referenced application is a little bit different - the ItemsSource is rebound. We will do our best to address this problem in one of the next internal builds.
