Custom Controls In WPF

Hello All,

I am new to WPF . I want to develop a custom control. Like a rounded text box by using two ellipses.
I do not want to hardcode the height and width of the ellipses in the Custom Control itself.
I want to expose two DependencyProperties and allow the consumer of the control to set these two properties.

Is this possible. where in I add the ref to the Lib , instantiate the custom control and then assign the dependency property which I have exposed thru the CustomControl Code.

Can you share somelinks which helps me solve this issue.

Pls help
Advance thanks.
