Column ShowColumnWhenGrouped attribute ignored when set in XAML

[Chuck]

I am a long time Telerik user, and I love the ShowColumnWhenGrouped attribute, I've wanted this functionality for a long time.  It works great when the user drags a column to the group bar, but when set in XAML with a column grouping defined in XAML, it is ignored.  Is this a bug, and is there a workaround?  Thanks.

Hi,

May I ask you to share how do you define the column grouping in XAML? Do you define a GroupDescriptor or a ColumnGroupDescriptor?

I use a group descriptor.  Is that wrong?  Can you give me an example of how to do it with a ColumnGroupDescriptor?

[Chuck]

My XAML looks like:

<telerik:GroupDescriptor Member="Type" SortDirection="Ascending" DisplayContent="Type">
     <telerik:GroupDescriptor.AggregateFunctions>
         <telerik:CountFunction />
     </telerik:GroupDescriptor.AggregateFunctions>
</telerik:GroupDescriptor>

Hi,

The GroupDescriptor is not associated with any column, it has a Member to group by instead. That is why the ShowColumnWhenGrouped attribute of a column does not react.
You could check the Programmatic Grouping section in our online documentation for more details and an example.

Is there a way to add an aggregate function to a ColumnGroupDescriptor?

[Dimitrina]

Hi,

You should directly define the AggregateFunctions for the respective column. Please note the ColumnGroupDescriptor is associated with a specific column and that is why there is not a need for it to also expose the option do define AggregateFunctions.

Ok, I finally got it.  It is working properly now, thanks.
