/* How to access Parent Form Methods from Child Form in .NET C#?
There may be 101 ways.
Simplest way I know is to create a Public Static variable to Carry your Parent form. :)
Here it is. */
//Add this code in the parent form
//declare the public static variable.
public static Parent ParentInstance;
//before you call the ChildInstance.Show(), assign the parent form to ur variable.
ParentInstance = this;
ChildInstance.Show();
//Add this code piece in the Child form
Parent.ParentInstance.YourMethodName();
/* Beauty is you don't need to declare your method as Static, which is not possible in most of the occasions [when u access form controls in ur method]*/
