I installed the wpftoolkit.msi and added a reference to it, but it doesn't get dipslayed in the toolbox, is there anything else that needs to be done? I followed the instructions from the code plex site, I can access some of the controls from code, only a few, I added WPFToolkit as a reference, does any other reference need to be added for the chart controls and so that they can be accessed from the toolbox?
EDIT: I added all dlls in the folder and still cannot access the chart control.
Answer: I provided an answer bellow you neeed to include a different namespace for the charts the default one from the codeplex site doesn't include all controls.
I believe this is the answer if you want to add the charting controls to your toolbox. If you just add a reference to what the codeplex site says you won't get all controls.
using Microsoft.Windows.Controls
doesn't work you need to include the reference name, if you click on properties for the reference name you can copy name, for charting it is:System.Windows.Controls.DataVisualization.Toolkit
For the toolbox:
Go to your toolbox, right click create a new tab. In the new tab right click choose items add all the controls from the
System.Windows.Controls.DataVisualization.Toolkit
namespace. You should have all of them in the toolbox.
