I have a RadGridView that is part of a datatemplate that I am creating at runtime via c#. All is good if I AutoGenerate the columns. If I try to create the GridViewDataColumns I have no way of adding them. Seems the Columns property is not exposed as a dependency property. Can you please look into this and suggest a work around or possible solution? In my example, RadGridView.Columns does not appear to be accessible.
FrameworkElementFactory radGridView = new FrameworkElementFactory(typeof(RadGridView));radGridView.SetValue(RadGridView.ShowGroupPanelProperty,false);radGridView.SetValue(RadGridView.ShowInsertRowProperty, false);Telerik.Windows.Controls.GridViewColumnCollection colCollection = new Telerik.Windows.Controls.GridViewColumnCollection();GridViewDataColumn dc = new GridViewDataColumn();dc.Header = "test"colCollection.Add(dc);radGridView.SetValue(RadGridView.Columns,colCollection);3 Answers, 1 is accepted

Hi Rod Yager,
Please, excuse for the late answer. Unfortunately you are hitting a framework limitation, so there is little to do, in order to make this approach work. The solution that comes to my mind is to customize the FrameworkElementFactory, setting the needed DependencyProperties and the set it as a visual tree of the respective template. On parent element's Loaded event, you may seek for the generated RadGridView in its template and add the columns. Please, let me know whether this approach meets your requirements.
Kind regards,

A framework limitation? How so? In .NET or in Telerik's construction of the GridView control? I am not really sure what you are suggesting for a solution.

Hello Rod Yager,
Mentioning limitations, I have meant the fact that one is not allowed to set non-dependency properties in FrameworkElementFactory's definition. Since "Columns" is not a dependency property, the approach you have described won't be valid. Alternatively you may add these columns at runtime, finding the RadGridView in the visual tree, or subscribing to an appropriate event. I have prepared an example project for you. It is attached for your reference.
All the best,
