Help me to getting value in another form (C#)

Hi ctlatd2,

C# is an object oriented language, evry form is a class.

You Need To this :

1. In form2 you need to writh a PUBLIC function that return a value.

2. In the new form "f" you need to call the function like this :

a. ((FrmMain)this.MdiParent).fnGetValue(); // if it's mdi form

b. Form2 f= new Form2() ;
f.fnGetValue() // in your case

Either you add a parameter of type TextBox to your Form2's constructor, so when you create an instance of your Form2, you simply calling it as:

private void button1_Click()
{
Form2 f = new Form2(textBox1);
f.Show();
}

Or simply change the modifier of your textBox1 from private (default) to internal; so your Form1's textBox1 will be visible for all the Forms within your project.

Example:

private void button1_Click()
{
Form2 f = new Form2(textBox1);
f.Tag = this;
f.Show();
}

On your Form2, you can simply make a call:

((Form1)Tag).textBox1

To get the TextBox from Form1.
