[Solved] Getting ColumnGroupDescriptor when Grouping is set programmatically

[Patrick]

Hello,

I'm trying to get a handle to the column[s] currently being grouped when the grouping is set programmatically. It's easy to get ColumnGroupDescriptor (which is great btw) when grouping is done via the UI. As in:

IEnumerable<ColumnGroupDescriptor> groups = grid.GroupDescriptors.OfType<ColumnGroupDescriptor>();
foreach (ColumnGroupDescriptor group in groups)
{
    //Do something...
}

When I programmatically add a group as in:

grid.GroupDescriptors.Add(new Telerik.Windows.Data.GroupDescriptor() { Member = "Category" });

I don't get the convenient list of ColumnGroupDescriptor during the OfType conversion (just an empty list), GroupDescriptors contains only a basic GroupDescriptor which doesn't seem to contain much or include the column. Is there a way that I'm missing to acquire the ColumnGroupDescriptor when I do this OR do you have another way to get an easy handle to the column, or perhaps the column's UniqueName? Thank you.

Hi,

 You should add ColumnGroupDescriptor instead plain GroupDescriptor to achieve your goal. 

All the best,

Ah, of course! Exactly what I should have done. I created my ColumnGroupDescriptor, assigned my column to it and added the ColumnGroupDescriptor to the GroupDescriptors. Thanks Vlad,
