Hi Team,
I am using RadDropDownButton in my project, which conatins 4 items. On selection of any item, one new window pops up.
My problem is, after the selection of item from dropdownbutton, it reamins open.
And our requirement is to close that dropdownlist as soon as selection is made.

Kindly let me know, howe can I achieve this.
I am puting my code here, which will give you better idea.

<telerik:RadDropDownButton>
 <telerik:RadDropDownButton.Content>
   <StackPanel Orientation="Horizontal">
            <Image Source="/Cirrus.Core.UI.Images;component/Images/new.png" Style="{StaticResource ToolBarButtonImage}" />
            <TextBlock Text="{Binding Source={StaticResource c}, Path=s.AddANewDevice}" Style="{StaticResource                         ToolBarButtonText}"  />
  </StackPanel>
 </telerik:RadDropDownButton.Content>
 <telerik:RadDropDownButton.DropDownContent>
           <ListBox ItemsSource="{Binding DeviceTypes}" DisplayMemberPath="Display" SelectedItem="{Binding   SelectedDeviceType, Mode=TwoWay}" Width="132" />                               
 </telerik:RadDropDownButton.DropDownContent>
</telerik:RadDropDownButton>    

Hi Shweta,

 I prepared a project for you demonstrating a possible approach. Basically, I use the DropDownOpened event of the DropDownButton and the SelectionChanged event of the ListBox. Please let us know if this satisfies you.

Hi Team,
Thanks for your response.
I tried your code, but I am getting button instance as null.  

 

private void ListBox_SelectionChanged(object sender, SelectionChangedEventArgs e) 

{  

   if (dropDownButtonOpened) 

    {  this.button.IsOpen = false; }

}

Hi Petar,
I am able to resolve my issue.
I just did an addiiotnla casting and it worked

 

private void button_DropDownOpened(object sender, RoutedEventArgs e) 

{  dropDownButtonOpened = true; 
   button = sender as RadDropDownButton; 

}

Hello Shweta,

 We are glad to hear that you have resolved this. Please feel free to ask if you need further assistance.
