[Solved] problem sorting RadGridView columns

[Ying]

I have binded a List to the RadGridView. can not sort the columns.
<telerik:RadGridView telerik:Theming.Theme="Office_Blue" x:Name="dg_feature_asbuilt_sort" Grid.Row="20" AutoGenerateColumns="False" Margin="5,5,5,0" MaxHeight="500">
<telerik:RadGridView.Columns>
<telerik:GridViewDataColumn DataMemberBinding="{Binding Attributes[Drawing_Id]}" Header="Drawing ID"/> <telerik:GridViewDataColumn DataMemberBinding="{Binding Atrributes[Block]}" Header="Block"/> </telerik:RadGridView.Columns>
</telerik:RadGridView>

Attache is the result i got when running the app. you can see the columns are not sortable. is there anything i need to set in the xaml or code behind?

Hello,

Please note that the Type of the property which you want to sort on should implement IComparable. What are the types of the properties you have bound to (Attributes[Drawing_Id] and Atrributes[Block])?

I have binded a List<Esri.ArcGIS.Client.graphic>
does the gridview support sorting on that? thanks

Hello,

Does the "Esri.ArcGIS.Client.graphic"  implement IComparable?
