Defining columns in RadDataGrid causes exception on load

[William]

If I comment out the columns section it loads. So how did you guys get to work? Dylan sent me a ChartViewTest project and I dropped this section in replacing the chart (that works) and it still threw and exception so I know it is not a requirements or configuration issue. What am I doing wrong. Running out of time on this eval.  Thanks. 

  xmlns:grid="using:Telerik.UI.Xaml.Controls.Grid" 

     <grid:RadDataGrid AutoGenerateColumns="False"
                                 SelectionMode="Single"
                                 SelectionUnit="Row"                                 
                                 >
                <grid:RadDataGrid.Columns>
                    <grid:DataGridTextColumn Header="Name"/>
                </grid:RadDataGrid.Columns>
            </grid:RadDataGrid>

I get this...

System.Runtime.InteropServices.COMException: Error HRESULT E_FAIL has been returned from a call to a COM component.
   at Microsoft.UI.Xaml.UIElement.Measure(Size availableSize)
   at Telerik.UI.Xaml.Controls.Grid.DataGridColumn.MeasureCellContainer(Double availableWidth, UIElement container)
   at Telerik.UI.Xaml.Controls.Grid.DataGridColumn.MeasureCell(GridCellModel cell, Double availableWidth)
   at Telerik.UI.Xaml.Controls.Grid.RadDataGrid.MeasureHeaderCell(GridHeaderCellModel cell)
   at Telerik.U

Hello William,

Thank you for the shared code snippet. 

In order to get started using the RadDataGrid, you can merge the Telerik themes ResourceDictionary in the application's Resources:

<Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <XamlControlsResources xmlns="using:Microsoft.UI.Xaml.Controls" />
                <ResourceDictionary Source="ms-appx:///Telerik.WinUI.Controls/Themes/Generic.xaml"/>
                <!-- Other merged dictionaries here -->
            </ResourceDictionary.MergedDictionaries>
            <!-- Other app resources here -->
        </ResourceDictionary>
    </Application.Resources>

I am also attaching the ChartViewTest project updated to demonstrate how the RadDataGrid can be setup. Do check it out and let me know, if it helps.

Far out! That works. Thanks!

Did I miss that?

I am glad to hear that you found the previous suggestion helpful. 

Indeed we have not included this information in the documentation. That said, I prepared a pull request to update the general Getting Started article and also the RadDataGrid one include this.

Of course, feel free to contact us again, if you have any other questions.
