WPF bind usercontrol's property to parent's property
===

I have created a usercontrol, which has 2 dependency properties. I want to bind those dependency properties to the mainViewModel's property, so that whenever something gets changed in the user-control the parent's property gets updated.

I tried, binding it normally but it didn't work. How can I bind the user-control's DP to the parent's property.

I tried this: 
<myUserControl UCDependencyProp1="{Binding Path=parentsProp1, Mode=TwoWay}" />

Thanks
