Hello,

I'd like to use a ColorEditor in a DropdownButton,
can you tell me how to prevent the dropdownbutton close when i move sliders...
i'd like to be able to select the right value for each slider before dropdowncontent close.

maybe with a "apply" button ?

thanks
Aurore

Hi Aurore,

 Could you please try setting the KeepOpen property of the DropDownButton to true ? This should prevent the DropDownContent from closing untill you click on the button. Please let us know if this satisfies you.

Kind regards,

Hi Petar,

I probably can try, but user still need to click twice to apply the same color for 2 different objects.

ok,

let suppose that instead of having one object on your grid you have several objects :
<ToggleButton  Margin="10" Click="ToggleButton_Click" Grid.Row="1">
          <Rectangle x:Name="oRect" Width="50" Height="50"   Fill="AliceBlue"/>
      </ToggleButton>
      <ToggleButton Margin="10" Click="ToggleButton_Click" Grid.Row="2">
          <Rectangle x:Name="oRect1" Width="50" Height="50"   Fill="AliceBlue" />
      </ToggleButton>
      <ToggleButton Margin="10" Click="ToggleButton_Click" Grid.Row="3" >
          <Rectangle x:Name="oRect2" Width="50" Height="50"  Fill="AliceBlue" />
      </ToggleButton>
      <ToggleButton Margin="10" Click="ToggleButton_Click" Grid.Row="4" >
          <Rectangle x:Name="oRect3" Width="50" Height="50"  Fill="AliceBlue" />
      </ToggleButton>

When you select one, (click on one togglebutton), choose a color (green).
After you select an other one, and try to choose the same color (green) : it is not possible in one click. If i use "keepopen", the user must click outside colorpicker to apply choosen clor, i don't think it is a good idea.
private void PredefSelectedColorChanged(object sender, EventArgs e)
       {
           if (oBtnSelected != null)
           {
               ((Rectangle)oBtnSelected.Content).Fill = new SolidColorBrush(((RadColorSelector)sender).SelectedColor);
               color.IsOpen = false;
           }
       }
 
       ToggleButton oBtnSelected = null;
       private void ToggleButton_Click(object sender, RoutedEventArgs e)
       {           
           oBtnSelected = sender as ToggleButton;
       }

oups,
I have mixed two of my questions about colorpicker...

The response i've made this morning is for clearing selectedcolor :  (http://www.telerik.com/community/forums/wpf/colorpicker/clear-selectedcolor.aspx).

Please accept my apologizes...

Well, the only problem i've seen by using KeepOpen attribute is that for the colorpicker tab, i want that the dropdown button close after one click.

Thanks for your ideas

Hi Aurore,

 is it possible for you to share your XAML and your exact user scenarios - the steps that the user should perform (for example 1.create color, 2.1. clicking outside the popup should close the button  3. While creating color , the popup stays open and etc). This will be the best way for use to get into your scenario quicker and find an optimal solution. Thank  you in advance.
