  Hi,
  
  I am using "RadColorPaletteView" to display custom colors.
  
  I need to change the application theme, when we select the color from the "RadColorPaletteView".
  
  I am using the following code in the SelectionChanged event to get the selected color.
  string strColor = ((RadColorPaletteView)e.OriginalSource).SelectedItem.ToString();
  
  I am able to get the color when I select the color for the first time. If I try to select another color it is returning the ((RadColorPaletteView)e.OriginalSource).SelectedItem as null.
  
  How can I get the selected color from the "RadColorPaletteView".
  
  I tried to use the "(((RadColorPaletteView)e.OriginalSource)).SelectedPaletteViewItem.Color". With this I am getting some missing assembly reference error.
  
  Please help.
  
  Regards,
  SivaPrasad.B

  Hello SivaPrasad Bevara,
  
  

  This appears to be a bug in the RadColorPalleteView. We logged it in our PITS(ColorPicker: RadColorPaletteView `s SelectionChanged event fires twice) and updated your telerik points accordingly. You will be soon able vote for this issue ( it will be uploaded in the next 24 hours). As a workaround you can do like so:

  privatevoidPalette_SelectionChanged(objectsender, Telerik.Windows.Controls.SelectionChangedEventArgs e) 
        { 
            if(this.palette.SelectedItem != null) 
            { 
                        string strColor = ((RadColorPaletteView)e.OriginalSource).SelectedItem.ToString();

            }            } 
        }

  Please accept our apologies for the inconvenience caused and feel free to ask if you need further help.
  
  Kind regards,
  Petar Mladenov
  the Telerik team
