WPF designer example data problem

[Markoniuss]

Hi, I have an issue, when I use Group Aggregates, see below

<telerik:RadGridView Name="radGridView1">
    <telerik:RadGridView.GroupDescriptors>
        <telerik:GroupDescriptor Member="tel">
            <telerik:GroupDescriptor.AggregateFunctions>
                <telerik:CountFunction Caption="Entries: "/>
            </telerik:GroupDescriptor.AggregateFunctions>
        </telerik:GroupDescriptor>
    </telerik:RadGridView.GroupDescriptors>
</telerik:RadGridView>

I get following error

Error   1   Invalid property or field - 'tel' for type: Customer   C:\Users\Martinek\Documents\My\Learning.Dot.Net\LINQ.2\LINQ.2\Window1.xaml   6   9   LINQ.2

But this only shows in WPF designer, I can easily compile code without any issues. Logically I believe that WPF designer use some sort of example data which does not contain "tel" column. So when I change column to "CustomerID" (this from example data) I get no errors at all.

Is there any possibility to modify example data shown in WPF designer to what I have from my SQL table. Or any other ideas?

Hello,

 Most probably you have old version of the grid. Can you try our latest Q2 2010 SP1 and let us know about the result?
