        </telerik:GridViewDataColumn>

    </telerik:RadGridView.Columns>

</telerik:RadGridView>
 
I changed the xaml code a little bit.
How i can bound Step.Outputs[].OutputType on
<telerik:GridViewComboBoxColumn Width="Auto" Header="Typ" ItemsSource="{Binding OutputTypes}"> 

public Step Step
{
    get{
        return this._step;}
    set{
    this._step=value;
    this.NotifyOfPropertyChange(() => this.Step);
    }
}

step has Outputs - ObserverableCollection<IOutput>
each output has OutputType (IOutput)

Hi,

 Thank you. 

Generally the reason why you can not add any entry, would be because the RadGridView does not know how to create the new object of the bound type. This is due to the fact that the bound items does not have a default constructor.

All the best,
