Hi,

I always get a KeyNotFoundException when I click on a RadioTool in my XamWebRibbon

ExceptionStackTrace:

I build the Ribbon in Codebehind

my Code:

var tab = new XamWebRibbonTabItem();
tab.Name = "TestTab";
tab.Header = "TestTab";
_Ribbon.Tabs.Add(tab);

var group = new XamWebRibbonGroup();
group.Id = "TestGroup";
group.Caption = "TestGroup";
tab.Groups.Add(group);

var menuTool = new MenuTool();
menuTool.IsQatCommonTool = true;
menuTool.Id = "TestMenuTool";
menuTool.Caption = "Filtering";
menuTool.MaximumSize = RibbonToolSizingMode.ImageAndTextLarge;
group.Tools.Add(menuTool);

var radio1 = new RadioButtonTool();
radio1.Id = "FILTER_TOP";
radio1.GroupName = "FilterGroup";
radio1.Caption = "Filter Row Top";
radio1.IsChecked = true;
radio1.Checked += radio1_Checked;
menuTool.Items.Add(radio1);

var radio2 = new RadioButtonTool();
radio2.Id = "FILTER_BOTTOM";
radio2.GroupName = "FilterGroup";
radio2.Caption = "Filter Row Bottom";
radio2.IsChecked = false;
radio2.Checked += radio1_Checked;
menuTool.Items.Add(radio2);

var radio3 = new RadioButtonTool();
radio3.Id = "FILTER_MENU";
radio3.GroupName = "FilterGroup";
radio3.Caption = "Filter Menu";
radio3.IsChecked = false;
radio3.Checked += radio1_Checked;
         
menuTool.Items.Add(radio3);

var radio4 = new RadioButtonTool();
radio4.Id = "DISABLE_FILTER";
radio4.GroupName = "FilterGroup";
radio4.Caption = "Disable Filter";
radio4.IsChecked = false;
radio4.Checked += radio1_Checked;
menuTool.Items.Add(radio4);

Hope you can help me finding the problem with this code.

Thanks alot.
