[Solved] How to get handle to CellTemplate control to manipuate

[Grr]

I am trying to put color picker in a dropdownbutton. I want once the user selects the color the dropdown should close.

My column defination

 <telerik:GridViewDataColumn Header="Color"
                    x:Name="Color"
                    DataMemberBinding="{Binding Path=ColorBrush, Mode=TwoWay}"
                    Width="40"
                    UniqueName="Color">
       <telerik:GridViewDataColumn.CellTemplate>
           <DataTemplate>
               <telerik:RadDropDownButton Background="{Binding Path=ColorBrush, Mode=TwoWay}"  
                     Name="ColorDropDown1"
                     Width="20" Height="15" DropDownWidth="187" CornerRadius="3" 
                     DropDownIndicatorVisibility="Collapsed" >
                                <telerik:RadDropDownButton.DropDownContent>
                                    <telerik:RadColorSelector 
                                        SelectedColor="{Binding Path=ColorBrush, Mode=TwoWay}" 
                                        SelectedColorChanged="RadColorPicker_SelectedColorChanged"/>
                                </telerik:RadDropDownButton.DropDownContent>
               </telerik:RadDropDownButton>
            </DataTemplate>
         </telerik:GridViewDataColumn.CellTemplate>

in code I am trying to get to the control by

private void RadColorPicker_SelectedColorChanged(object sender, EventArgs e)
        {
            (mRadGridView.SelectedItem as ChannelProperty).ColorBrush = new SolidColorBrush((sender as RadColorSelector).SelectedColor);
            RadDropDownButton button = FindVisualChildByName<RadDropDownButton>(this, "ColorDropDown1");
            button.IsOpen = false;
        }
 
        private static T FindVisualChildByName<T>(DependencyObject parent, string name) where T : DependencyObject
        {
            for (int i = 0; i < VisualTreeHelper.GetChildrenCount(parent); i++)
            {
                var child = VisualTreeHelper.GetChild(parent, i);
                string controlName = child.GetValue(Control.NameProperty) as string;
                if (controlName == name)
                {
                    return child as T;
                }
                else
                {
                    T result = FindVisualChildByName<T>(child, name);
                    if (result != null)
                        return result;
                }
            }
            return null;
        }
It only works for first row but not for all. Any help?

Hi Giri,


I would suggest you to create your own custom editor with RadGridView as it is shown in this online documentation article.
