No groupable column doesn't work?

[Larry]

It seems if I have a column with IsGroupable set to false, I can still drag and drop it to the group panel and grouping still works.

I know this can be workaround by handling and canceling the Grouping event, but are you guys planning a fix for this?

Thanks

Hello,

 I'm unable to reproduce such issue in this demo:

My mistake, Apparently it only breaks when data source is dynamic objects. Here is an example:

xaml

 

 

 

 

 

<telerik:RadGridView ItemsSource="{Binding Data}" AutoGenerateColumns="False"
                             MinHeight="386" SelectionMode="Extended" IsReadOnly="True" Name="DataGrid">
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn x:Name="NameColumn" DataMemberBinding="{Binding Name}" IsGroupable="False" Header="Name"/>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding LastUpdate}" Header="Last Update"/>
            </telerik:RadGridView.Columns>
        </telerik:RadGridView>

 

 

 

DataContext:

ObservableCollection<DummyDataItem> _data;
        ObservableCollection<DummyDataItem> Data
        {
            get
            {
                if(_data== null)
                {
                    _data= new ObservableCollection<DummyDataItem>();
                    _data.Add(new DummyDataItem());
                }
                return _data;
            }
        }

DummyDataItem.cs:

class DummyDataItem : DynamicObject
    {
        public override bool TryGetMember(GetMemberBinder binder, out object result)
        {
            result = "test";
            return true;
        }
    }

Hi,

 Are you using our latest official version (Q3 2012)?

Nope I used q2 sp2. It's going to take a while for us to migration to q3

We are at 2012.3, and the problem is still there.

Hello,

 The grid on our demo is also bound to dynamic objects however you can group normally.
