Add Custom UserControl on same application page

[RaoBase]

I would like to create a simple wpf control with a textbox and OK and Cancel button
This tool will be accessed from the Menus and display on top of the current map i.e. on same page similar to the Measure tool.
Any suggestions?

I understand you would like to use a UserControl just like the Measure Tool, but I simply use a MessageBox, it has label and you can choose between which buttons you want on it.

You can pick between the System.Windows.Forms.MessageBox or use the WPF version.
