Sorting/Grouping on a Dictionary<string, object>

[Sunil]

Hi Guys,

I have a GridView whose ItemsSource is bound to a collection of say ObjectX.

ObjectX has a Dictionary<string, object> in it where I am storing some context data.
I define the columns in xaml like so:

<telerik:GridViewDataColumn Header="Col1" DataMemberBinding="{Binding Path=Context[key1]}"

<telerik:GridViewDataColumn Header="Col2" DataMemberBinding="{Binding Path=Context[key2]}" />
<telerik:GridViewDataColumn Header="Col3" DataMemberBinding="{Binding Path=Context[key3]}" />

Where Context is the Dictionary collection. This works great (I am able to display the correct data). But I cannot do any grouping/sorting/filtering on these columns. I have tried setting the GroupMemberPath and SortMemberPath with no luck.
What am I missing? 

Any help would be greatly appreciated.

Hi,

 I would suggest you to check this forum thread where a similar topic is discussed.

Thanks for the response!

I don't think this will work because I also need to display columns that ARE NOT part of the Dictionary. For example:

public class ObjectX
{
	public string Name { get; set; }
		

	public Dictionary<string, object> Context { get; set; }
}
In the grid, I would like to display my "known" columns (Name) plus my dynamic columns (the Dictionary).
So the ItemsSource of the grid is ObservableCollection<ObjectX>. Like I said before, I can display the information
correctly, but I cannot perform grouping or sorting in the dynamic columns. 

Any other ideas?

Hi,

If you have some static columns, then you could define them initially when defining the RadGridView.
