Question

If I create a partial class of Form1 is there a way to access the controls that are on the form designer thru intellisense?

namespace PracticeUI1
{
    public partial class Form1 : Form
    {
        Button1.Text = "blah";
    }
}

Answer 1

It will depend where you will initialize your button, lets say you are declaring in the same class and you do it as

private System.Windows.Forms.Button button1; 

inside Class Form, than you will be able to reach only from this part of class Form or from another partial class form in another file, but you woudnt be able to access it from the same namespace. I think you got the logic.

By the way for the answer with

this.button1

it’s actually doesn’t matter if you will include this. or you will not
