having problems getting the extended WPF toolkit to work - WYSIWYG designer breaks

Aug 4, 2011 at 3:45 PM

Hi, I've been trying to get this working for over a day now.

I'm installing the toolkt as instructed (Win7, .Net 4, VS2010):

  1. Install .NET Framework 4.0
  2. Download the ExtendedWPFToolkit_Binaries
  3. Unzip the ExtendedWPFToolkit_Binaries.zip
  4. Reference the binaries in your project:
  5. Reference WPFToolkit.Extended.dll in your project
  6. Add a using statement ("using Microsoft.Windows.Controls;") to the top of .cs files
  7. Add a new xmlns (for example, xmlns:extToolkit="http://schemas.microsoft.com/winfx/2006/xaml/presentation/toolkit/extended") to the top of XAML files
  8. Remember to use the namespace prefix (in the above example, <extToolkit: ...>) in the body of your XAML

My apps run fine, but the WYSIWYG WPF Window editor won't work as soon as I reference a toolkit control - I get no compilation errors, but the editor says Problem Loading / Reload The Designer.

My XAML is this:

<Window x:Class="FileNameChanger.Misc.XAMLPlay"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:wpftoolkit="http://schemas.microsoft.com/winfx/2006/xaml/presentation/toolkit/extended"
Title="XAMLPlay" Height="300" Width="300">
<Grid>
<wpftoolkit:Calculator>

</wpftoolkit:Calculator>
</Grid>
< /Window>

Does anyone have any help / advice please?

Thanks a lot!
