Hello,
Using Infragistics2.Win.UltraWinToolbars.v10.3, I have been trying to host a custom WPF UserControl in the WinForms ribbon using a ControlContainerTool containing an ElementHost.
Whilst the designer correctly renders the component, when running the ElementHost region is rendered as an opaque blue colour. The component is there (you can type, copy text etc). But it is not visible.
Is this supported? Do you expect it to be able to work? Can you suggest anything to get it working?
Sample project: here.
I have been able to verify your results and am currently investigating if there is any way around to do this.
Meanwhile, please feel free to let me know if a question about our toolset comes up on your mind.
You could put the ElementHost in a Panel and assign the Panel to the Control property of the ControlContainerTool. It was Chris Shea who shed light on this, I tried it with your sample and it works fine.
Please do not hesitate to contact me if you need any additional assistance.
