How to get the selected color title on the server side

[Jonathan]

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

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,
