Problem using RichTextBoxFormatBar

Apr 17, 2012 at 10:49 AM

I've been trying to use the RichTextBoxFormatBar but I can't get the project to compile and I get these two errors: 

"The attachable property 'FormatBar' was not found in type 'RichTextBoxFormatBarManager"

"The type 'toolkit:RichTextBoxFormatBar" was not found. Verify that you are not missing an assembley reference and that all referenced assemblies have been built"

I'm using the WPFToolkit.Extended.dll for .Net 4 and have a reference to it in my project. The code is as follows:

  <UserControl x:Class="TestWPF_Richtextbox.UserControl1"
             d:DesignHeight="300" d:DesignWidth="300">
                <toolkit:RichTextBoxFormatBar />


I'd be very grateful for any help, this is driving me up the wall!

On my end, everything works great.


I know you said that you have added a reference to the WPFToolkit.Extended.dll assembly in your project, but if you look at your References folder, do you see a yellow triangle next to the reference to "WPFToolkit.Extended"?  If it is the case, you have a missing assembly.  Try to remove the assembly from your project and add it again.

Thanks for your response.

The References folder contains WPFToolkit.Extended and there are no warning triangles or anything of the like. I've tried re-starting VS and removing and re-adding the reference but it doesn't make any difference.

I've also asked a colleague to create a project and have sent him the DLL to reference but he has the same problem. I'm using V. of the DLL.

Sorted - my own stupid fault. I'd forgot to unblock the zip file when I downloaded it (as per your instructions...).

Hopefully this post will stop anyone else making the same daft mistake!
