Access usercontrol public methods from parent form

Question

Hi,

 I have a parent form named 'MainForm' & usercontrol as a child named UcTxView. UcTxView has a public method called 'Save()'. I want to call this 'Save()' method from parent form (MainForm). 'UcTxView' wil be added on demand only, it means not in GUI designing time. How I can solve this.

 

all the comments & ideas will be appreciated.
