The type 'DataRowView' does not contain a public property named 'UnitColumn'

Hello,
I am running into the error: "The type 'DataRowView' does not contain a public property named 'UnitColumn'" error when trying to edit a cell in the radGridView cell. I am dynamically creating a DataTable to bind to. I have copied the xaml, along with the codebehind for a small sample that illustrates the issue.
Thanks for your help!

Three level hierarchy support

Hi,

I am looking to implement a three level hierarchy whereby the child grids are determined on the run time. For example if we select an option from a combo box present on the parent grid, it will create a child grid. Similarly we could repeat the same scenario for the child grid as well. I am looking into doing this by creating hierarchical templates for both the parent and the child:

<telerik:RadGridView x:Name="rgvData" CanUserFreezeColumns="False" GridLinesVisibility="Horizontal" ItemsSource="" IsReadOnly="True" AutoGenerateColumns="False">

<telerik:RadGridView.ChildTableDefinitions>

<telerik:GridViewTableDefinition />

</telerik:RadGridView.ChildTableDefinitions>

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding OrderDate}" Header="Order Date" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding EmployeeID}" Header="Employee" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding Freight}" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding ShipCountry}" Header="Ship Country" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding ShipCity}" Header="Ship City" />

</telerik:RadGridView.Columns>

<telerik:RadGridView.HierarchyChildTemplate>

<DataTemplate>

<telerik:RadGridView x:Name="RadGridView1" CanUserFreezeColumns="False" AutoGenerateColumns="False" ShowGroupPanel="False" IsReadOnly="True">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding CustomerID}" Header="Customer ID" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding Address}" Header="Address" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding City}" Header="City" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding Country}" Header="Country" />

</telerik:RadGridView.Columns>

</telerik:RadGridView>

</DataTemplate>

</telerik:RadGridView.HierarchyChildTemplate>

</telerik:RadGridView>

// The Child will host another template that will define it's own child.

What would be the best way to tackle this scenario. Should I just go by creating the grids through code behind? I would like to stick to xaml. Any pointers would help me decide !

Thanks,
Farhan

Clear selection with keyboard?

The RadComboBox has a "clear selection button" enabling the user to clear the selection of the combobox. Is it possible to do the same thing with the keyboard or do I have to implement that myself?
