New to WPF and problem with Style in Resource Dictionary

[danparker276]

I've been working with silverlight mostly, but I'm converting an app to WPF.  I'm using a mystyle.xaml resource dictionary and it's compiling ok, but I get this error message when I debug the program, 'Failed to create a 'TargetType' from the text 'telerik:RadDatePicker'. ...
The initelisense says it's ok and it compiles.  The project it configured with the dropdown Telerik->RadControls for WPF ->Configure Project and I have all the references.

Also, I don't see the Telerik controls in the toolbar to the left.  Even when I try to 'Launch Toolbox Configurator', it's doesn't do anything.  This doesn't bother me since I usually don't use the toolbox, but it may be related.  Maybe I'm missing something on my install

Seems like when I add my Source to the resource directory, I can't add the directory name or it will fail.  Must be a WPF thing

This works:

<ResourceDictionary.MergedDictionaries>
    <ResourceDictionary Source="StyleBrush.xaml" />
    <ResourceDictionary Source="StylesCommon.xaml" />
</ResourceDictionary.MergedDictionaries>

This won't (either one), I'm not sure why.  It's ok though, it was just different than silverlight

<ResourceDictionary.MergedDictionaries>
    <ResourceDictionary Source="/Application;component/StyleBrush.xaml" />
    <ResourceDictionary Source="Assets/StylesCommon.xaml" />
</ResourceDictionary.MergedDictionaries>

Hello Dan,

 

Will you please check the following thread and let us know how this works for you? 
As per your question about the missing controls in the toolbox you may review the following help article. 
In order to avoid such problems it is essential to ensure that you do not have installed multiple versions of Telerik RadControls/WPF.  



I look forward to hearing from you!
