Hi all,

I'm currently evaluating the beta version (Q3 2011) of the Telerik Silverlight bêta controls.
In a RadGridView, I have 3 frozen columns (FrozenColumnCount=3), and some others columns that are dynamically generated...

My goal is to create a ColumnGroup for the 3 first 'static' frozen columns, and then some other groups for the dynamically created columns. But at runtime, I get a ArgumentOutOfRangeException.

Could someone help me on this?
Greetings,

Nicolas

Hi again,

After further investigation, I found that the problem comes from a frozen GridViewDataColumn with the property IsVisible set to False. Changing it to True solve the problem, but now I've got a visible column that should be hidden.... Changing FrozenColumnCount to 2 or 3 did not help.

Any clue !?
Cheers,

Nicolas

I found a workaround:
On the column, set the following attribute:  IsVisible="True" Width="0" MinWidth="0"

But setting IsVisible="false" would still be the best solution. Is this a bug!?
