Hi there,

I'm trying to get the multiselection of the RadGridView working. I have a class Building with a Property IsSelected. With the Selection_Changed event i set/unset the property of the item. Is it possible to bind to the Building.IsSelected, so each row gets selected, if its object.IsSelected is true?

I know about the solution with behaviors, but I'd like one without it.

A little sample here:

<telerik:RadGridView x:Name="BuildingListGrid" ItemsSource="{Binding BuildingList}" EnableRowVirtualization="True"
                                 SelectionUnit="FullRow" SelectionMode="Extended" SelectionChanged="MasterBuildingListGrid_OnSelectionChanged">     <telerik:RadGridView.Columns>
         <telerik:GridViewDataColumn DataMemberBinding="{Binding Building.Name}" Header="Column2" />

     </telerik:RadGridView.Columns>

</telerik:RadGridView>

 

public class Building : INotifyPropertyChanged
{
    public Building(Building building){}
    public bool IsSelected
    {
        get { return _isSelected; }
        set
        {
            if (value == _isSelected) return;
            _isSelected = value;
            OnPropertyChanged();
        }
    }

    public string Name { get; set; }

}

I also tried this with:
<Style TargetType="telerik:GridViewRow">
 <Setter Property="IsSelected" Value="{Binding IsSelected, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
</Style>

 

and deactivated RowVirtualization. But still doesn't work.

 

Greetings Robin

Hi Robin,

Generally, the recommended approach for such requirement is demonstrated in the Binding Selected Items From View Model SDK Example. Can you please verify whether this is the example to which you referred? Are there any obstacles to adopting the approach demonstrated in it?
