Hi,

I have just download build 2009.2 813 which fixed an issue we were having, however it has broken something else.

If a Grid has no records in its item source and the ColumnsWidthMode is set to FIll I get the following exception:

Message="'-3' is not a valid value for property 'ViewportSize'."

The xaml code for the Grid is:

<telerik:RadGridView x:Name="radGridViewNotes"   
                     AutoGenerateColumns="False"   
                     ColumnsWidthMode="Fill"   
                     Grid.Row="2"   
                     IsReadOnly="True" 
                    
DataLoaded="RadGridViewNotes_DataLoaded" 
                     telerik:StyleManager.Theme="Office_Black">  
    <telerik:RadGridView.Columns> 
        <telerik:GridViewDataColumn Header="Subject" DataMemberPath="Subject" /> 
        <telerik:GridViewDataColumn Header="Creation Date" DataMemberPath="DateAdded" /> 
    </telerik:RadGridView.Columns> 
</telerik:RadGridView> 

If I change the ColumnsWidthMode to "None" or "Auto" it works fine.

Regards,
Glen

Hello Glen,

I have prepared a sample application and tried to reproduce the exception error message that you have described, but unfortunately I was not able to.
Can you please examine the project that I have attached and tell me how to reproduce the behavior that you are experiencing on your end.

Maybe I am doing something differently than you and that is why I cannot reproduce the behavior. Or maybe you can configure my sample project so that it behaves like your project and attach it back along with the instructions on how to make it happen.

Best wishes,

I have the same problem:

Window property:
  SizeToContent="WidthAndHeight"

The radgridview is wrapped in a scrollviewer.

All the best,
Thomas

Hello Thomas,

We have already fixed a problem related to the ViewportSize (similar to the described one) which we had reproduced when the following preconditions were available:

1. Window's SizeToContent="WidthAndHeight"
2. RadGridView is wrapped in ScrollViewer with HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto" properties set.
3. RadGridView is bound to an empty itemsource
4. RadGridView's property ColumnsWidthMode =Fill

I have updated your Telerik points for helping us identify  this issue.

The fix will be available in our latest internal build(this Friday). But we still cannot be sure if this fix will fix the issues you have. That's why it would be best if it is possible to send us a sample project where we can reproduce the problem.

Hello Justin,


You get this error because this property no longer exists. In order to achieve the same effect set ColumnWidth property of RadGridView to star:

<telerik:RadGridView x:Name="radGridView1" ColumnWidth="*" ....../>
