Sort dynamic data with ColumnSortDescriptor

[Stavroula]

Hallo Telerik,

I want to sort the Rows in my Grid. I have accomplished this with the event handler "RadGridView_Sorting". My data are all strings, so I use an IComparer to sort the data (Integers) and then bind them to the RadGridView.
My data is sorted when I load the data for the first time, but the GridView doesn't show the sorted Column. With the following code, I get the sorted column. 

<telerik:RadGridView.SortDescriptors>
        <telerik:ColumnSortDescriptor Column="{Binding Columns[\Title\], ElementName=radGridView}" SortDirection="Ascending"/>
    </telerik:RadGridView.SortDescriptors>

Can I use the code with dynamic binding of the column? For example something like this:

<telerik:RadGridView.SortDescriptors>
        <telerik:ColumnSortDescriptor Column="{Binding Columns[\{Binding SortMember}\], ElementName=radGridView}" SortDirection="{Binding SortDirection}"/>
    </telerik:RadGridView.SortDescriptors>

When I bind the SortDirection, it works. But how can I bind the column to be sorted dynamically?

One more question: I have the data of the RadGridView bound to a collection in MVVM. When I load the RadGridView for the first time, I expect the sorting_event to be called. Why does it not happen? 

Best Regards

Hello,

What do you mean that the GridView does not show the sorted column? Have you defined such a column? Would you please share the code for your column's definition? An image showing the result you got would be helpful as well.

Generally the Sorting event is a UI event and it will be raised only based on user interaction, i.e. when the user clicks on the column's header to invoke sorting.
