Hello,

Is it possible to prevent drag operation when an user is using a GridSplitter to resize column/row ?

For example :

    
                    <telerik:RadTreeView IsDragDropEnabled="True" ItemTemplate="{StaticResource TreeItemTemplate}">  
        
                        <telerik:RadTreeView.ItemContainerStyle> 
        
                            <Style TargetType="{x:Type telerik:RadTreeViewItem}">  
        
                                <Setter Property="HorizontalContentAlignment" Value="Stretch"/>  
        
                            </Style> 
        
                        </telerik:RadTreeView.ItemContainerStyle> 
        
                        <telerik:RadTreeView.Items> 
        
                            <Control Name="control1" Tag="Some text for control1" /> 
        
                            <Control Name="control2" Tag="Some text for control2" /> 
        
                        </telerik:RadTreeView.Items> 
        
                    </telerik:RadTreeView>

    
                        <DataTemplate x:Key="TreeItemTemplate">  
        
                            <Border BorderThickness="1" BorderBrush="LightGray" Margin="2" CornerRadius="5">  
        
                                <Grid> 
        
                                    <Grid.ColumnDefinitions> 
        
                                        <ColumnDefinition Width="Auto"/>  
        
                                        <ColumnDefinition Width="*"/>  
        
                                    </Grid.ColumnDefinitions> 
        
                                    <TextBlock Grid.Column="0" Text="{Binding Name}" Margin="3,0,10,0"/>  
        
                                    <GridSplitter Grid.Column="0" Width="1" Background="LightGray" ResizeDirection="Columns"/>  
        
                                    <TextBlock Grid.Column="1" Text="{Binding Tag}" Margin="3,0,0,0"/>  
        
                                </Grid> 
        
                            </Border> 
        
                        </DataTemplate>

Is there any solution ? I tried t define dragDrop:RadDragAndDropManager.AllowDrag="False" on GridSplitter but this doesn't work.

I have the same problem using RadDragDropManager in a templated list (Some draggable items contain Slider).

Thanks,
Guillaume.

Hello,

I found a solution :

    
            <GridSplitter Grid.Column="0" Width="1" Background="LightGray" ResizeDirection="Columns" dragDrop:RadDragAndDropManager.AllowDrag="True" dragDrop:RadDragAndDropManager.DragQuery="GridSplitter_DragQuery"/>

    
                    private void GridSplitter_DragQuery(object sender, Telerik.Windows.Controls.DragDrop.DragDropQueryEventArgs e)  
        
                    {  
        
                        e.QueryResult = false;  
        
                        e.Handled = true;  
        
                    }

Thanks,
Guillaume.
