How to Call a window form into a tabcontrol in wpf

Question

hi everyone,

 

I am new to wpf , and have a little knowledge in C#.

I designed a form with some buttons on the left dock of dock panel, and the center part with a tabcontrol.

 

So when i click a button in the  left dock, i need to have a tab in the center dock, with controls I designed in other forms with exact positions.

 

For eg:

 

If I click the user button, I need the user.xaml form to be displayed in the tabcontrol.

If I click the customer button, I need the customers.xaml form to be displayed.

 

I have done it in C# but I have no idea in wpf.

 

Thank You
