  Hello,
  
  I setup a custom color picker in a radgrid column like so:
  
  

  <telerik:GridTemplateColumn 

      DataField="Color"

      UniqueName="Color"

      SortExpression="Color"

      HeaderText="Color"

      HeaderStyle-Width="100" 

      ItemStyle-HorizontalAlign="center"                                        

      AllowFiltering="false">

      <ItemTemplate>

          <asp:Label id="lblColor" runat="server" ></asp:Label>

      </ItemTemplate>

      <EditItemTemplate>

          <telerik:RadColorPicker ID="RadColorPicker1" Runat="server"  Skin="WebBlue" Preset="None" >

             <telerik:ColorPickerItem Title="rsCategoryDarkBlue" Value="#202B3F" />

             <telerik:ColorPickerItem Title="rsCategoryBlue" Value="#CCCCFF" />

             <telerik:ColorPickerItem Title="rsCategoryDarkGreen" Value="#2B3F20" />

             <telerik:ColorPickerItem Title="rsCategoryGreen" Value="#D0ECBB" />

             <telerik:ColorPickerItem Title="rsCategoryDarkRed" Value="#3F2020" />

             <telerik:ColorPickerItem Title="rsCategoryOrange" Value="#EDD5B7" />

             <telerik:ColorPickerItem Title="rsCategoryPink" Value="#F1DCFF" />

             <telerik:ColorPickerItem Title="rsCategoryRed" Value="#ECBBBB" />

             <telerik:ColorPickerItem Title="rsCategoryViolet" Value="#540042" />

             <telerik:ColorPickerItem Title="rsCategoryYellow" Value="#FFFAC5" />

          </telerik:RadColorPicker>

      </EditItemTemplate>

  </telerik:GridTemplateColumn>

  
  I'd like to be able to grab the title of the selected color on the server side.
  

  protected void radGridStages_InsertCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)

  {

      //Get the GridEditFormInsertItem of the RadGrid     

      GridDataInsertItem insertedItem = (GridDataInsertItem)e.Item;

      //string EmployeeID = (insertedItem["EmployeeID"].Controls[0] as TextBox).Text;   

      try

      {

              //load the lookup

              Stage _stage = new Stage();

              //change the name

              _stage.Name = (insertedItem["Name"].Controls[0] as TextBox).Text;

              _stage.Code = (insertedItem["Code"].Controls[0] as TextBox).Text;

              _stage.Color = (insertedItem["Color"].Controls[1] as RadColorPicker).SelectedColor.ToArgb();

              //_stage.CssStyle = (insertedItem["Color"].Controls[1] as RadColorPicker).SelectedColorTitle;

              _stage.Active = (insertedItem["Active"].Controls[0] as CheckBox).Checked;

              StageService.Save(_stage);

              radGridStages.Focus();

      }

      catch (Exception ex)

      {

          lblMessage.Text = "Unable to insert Stage. Reason: " + ex.Message;

          e.Canceled = true;

      }

  }

  
  The problem is that there is no attribute server side to grab the title.  I could put in a long-winded select case statement but it seems like it should be easier.
  
  Thanks
  Jonathan

  Hi Jonathan,
  The RadColorPicker control does not have a property that returns the title of the selected color picker item. You can use, however, the following method to get that title:
  

  private string GetSelectedTitle(RadColorPicker picker)

  {

      var selectedColor = picker.SelectedColor;

      foreach (ColorPickerItem item in picker.Items)

      {

          if (item.Value == selectedColor)

              return item.Title;

      }

   

      return string.Empty;

  }

  
  
  Kind regards,
