Passing value from one to another form

Introduction:

Here, I am creating a window form application and passing value from one form to another form. For doing this, set the "Modifiers" property of control and assign value to it from another form.

Now, take a window form application. Here I am taking Form1 and arrange UI controls as given in below figure.



Add another form in your application and take a Label control on new form. Screen - shot is given below.



Now, go to "Modifiers" property of label and set it to "Public".



Write the following code on button click event of Form1.

private void btnok_Click(object sender, EventArgs e)
         {
             Form2 obj = new Form2();
             obj.label1.Text = "Hi, " + textBox1.Text;
             obj.Show();
         }

Now run the application.

Output:



Click the "ok" button. It will show the textbox value on Form2 from Form1.
