How to change form2 color on button click , calling the changeColor method of form1:

[snehasismishra1]

Hi,

I have two forms. Let say, form1 and form2. in form1 class, i have method ChangeColor() and i am calling this method in button click event of form2. But it is not changing the color of form2.

Please find the below code:
Below code is for form1, where on click of Button1, form2 is opening.

public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
 
 
        private void button1_Click(object sender, EventArgs e)
        {
            Form2 fm2 = new Form2();
            fm2.Show();
        }
        public void changecolor()
        {
 
            this.BackColor = Color.Red;
            this.Refresh();
        }
 
 
    }

Below code is for form2, where on click of button2, changecolor() i am calling. But unable to change the color of the form2.

public partial class Form2 : Form
    {
        public Form2()
        {
            InitializeComponent();
        }
 
        private void button1_Click(object sender, EventArgs e)
        {
              Form1 frm1=new Form1();
              frm1.changecolor();
        }
    }

Please suggest.

Thanks,

Pass an object to changecolor() of form1 then make changes to changecolor() like this in form1.

  public void changecolor(Form2 frm2) 
        { 
 
            frm2.BackColor = Color.Red; 
            frm2.Refresh(); 
        }
