Hi,
I've created a partial class : Control for designing the shape of my polygon.
It works well but there's one problem that I tried to find on net but I get nothing.
I've created one int named 'size'. Then I created a function named 'Growing' for 'get' and 'set'.
When I created an object from that class, I just type on the object name.Growing, then I can 'get' the size and 'set' the size.
This no problem.
The problem exist when I created as follow:
private void Grow(object sender, EventArgs e)
{
Control controlAll = (Control)sender;
}
This 'controlAll' is use to track which polygon I choose.
but when I run this line of code, it seems like controlAll can't get to the function I declared in the class "Growing"
controlAll.Growing = 50; // ERROR WENT HERE
Is there any ways to make the control to identified the function that I created in the class ? Any idea ?

As the Control class doesn't have a Growing property, you need to cast it to the actual type of the Control. If the class name is MyControl then the offending line would need to be:
((MyControl)controlAll).Growing = 50;
