Type 'RadToolBar' Was Not Found

[KKalik]

I'm creating a RadToolBar user control. When I run the control in my application I get the below error.

Error:
{System.Windows.Markup.XamlParseException: The type 'RadToolBarTray' was not found. [Line: 8 Position: 63] ---> System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.
   at System.Collections.Generic.Dictionary`2.get_Item(TKey key)
   at System.Windows.ResourceManagerWrapper.GetResourceForUri(Uri xamlUri, Type componentType)
   --- End of inner exception stack trace ---
   at System.Windows.Application.LoadComponent(Object component, Uri resourceLocator)
   at Application.Presentation.Controls.DataSetToolBarCtrl.InitializeComponent()
   at Application.Presentation.Controls.DataSetToolBarCtrl..ctor()}

My simple RadToolBar Xaml:

<UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
        xmlns:telerikQuickStart="clr-namespace:Telerik.Windows.Controls.QuickStart;assembly=Telerik.Windows.Controls"
         x:Class="Application.Presentation.Controls.DataSetToolBarCtrl"
        HorizontalAlignment="Center" VerticalAlignment="Center">

    <telerik:RadToolBarTray VerticalAlignment="Center" Margin="10,0,0,0">
        <telerik:RadToolBar>
            <Button Tag="Print" x:Name="btnPrintGrid" ToolTipService.ToolTip="Print Grid">
                <Image Width="16" Height="16" Source="/Application.Client;component/Images/print.png" />
            </Button>
            <Button Tag="Excel" x:Name="btnExportGrid" ToolTipService.ToolTip="Export Grid to Excel">
                <Image Width="16" Height="16" Source="/Application.Client;component/Images/excel.png" />
            </Button>
        </telerik:RadToolBar>
    </telerik:RadToolBarTray>

</UserControl>

Hi Katelin,

We are not aware of such an existing issue. Could you please take a look at the attached project and let me know if I am missing anything. I'd be glad to further assist you. 

All the best,

Hi Kiril,

I plugged in your solution and it did not solve the issue. I did notice that the RadToolBar is missing from my VS Toolbox. I have attached a photo of what I'm seeing.

Hi Katelin,

We are already aware of the issue where RadToolBar does not appear in the VS toolbox. Unfortunately we are not aware of an existing workaround. We will contact you as soon as we manage to fix the issue. Thank you for the cooperation and understanding.

Kind regards,

Eureka!!

This turned out to not be a specific Telerik control issue, but an integration of controls into LightSwitch issue. The examples provided for the control do not include the "x:Name" property for the RadToolBar or RadToolBarTray which are required to load controls into a LightSwitch application. I have attached the modified code below:

<UserControl x:Class="Application.Presentation.Controls.TEST"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
        xmlns:telerikQuickStart="clr-namespace:Telerik.Windows.Controls.QuickStart;assembly=Telerik.Windows.Controls"
        HorizontalAlignment="Center" VerticalAlignment="Center">
    <telerik:RadToolBarTray x:Name="myToolBarTray" VerticalAlignment="Center" Margin="10,0,0,0">
        <telerik:RadToolBar x:Name="myToolBar">
            <Button Tag="Print" x:Name="btnPrintGrid" ToolTipService.ToolTip="Print">
                <Image Width="16" Height="16" Source="/Application.Client;component/Images/print.png" />
            </Button>
            <Button Tag="Excel" x:Name="btnExportGrid" ToolTipService.ToolTip="Export to Excel">
                <Image Width="16" Height="16" Source="/Application.Client;component/Images/excel.png" />
            </Button>
        </telerik:RadToolBar>
    </telerik:RadToolBarTray>
</UserControl>

Thank you for your help Kiril.
