Hi,

I am using the example I found here to dinamically insert values into RadGridView. However, this example does not allow controling the properties of the generated columns like "IsFilterable" or "IsGroupable".
To implement this functionality, I modified the RadGridView to allow the indication of Column Definitions.

When the ColumnDefinitions property is changed, the following code is executed:
static void ColumnDefinitionsChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e)
        {
            var gridView = sender as i9rGridView;
 
            gridView.Columns.Clear();
 
            var columnDefinitions = e.NewValue as ObservableCollection<IAttributeDefinition>;
            if (columnDefinitions != null && columnDefinitions.Count > 0)
            {
                gridView.AutoGenerateColumns = false;
                foreach (var columnDefinition in columnDefinitions)
                {
                    gridView.Columns.Add(new GridViewDataColumn() { HeaderCellStyle = Application.Current.Resources["GridViewHeaderCellStyle"] as Style, UniqueName = columnDefinition.Code, Header = columnDefinition.Text, DataType = columnDefinition.DataType, IsReadOnly = columnDefinition.AccessLevel != AccessLevel.EDITABLE ? true : false, IsVisible = columnDefinition.AccessLevel != AccessLevel.INVISIBLE ? true : false, IsGroupable = false });
                }
            }
        }

All the properties work like I want but "IsGroupable = false" is ignored and all the columns allow grouping.

How can I solve this issue?
