You mean MDI? or just you need to open Form2 from Form1 and use some values in Form1 user entered in Form2??

For second case, just create another Form let say it called Form2, some public members (TextBox, ListBox, etc...)

Add this code in Form1 to open Form2
c# Syntax (Toggle Plain Text) 
  1. Form2 form2 = new Form2();
  2. fom2.ShowDialog();//enforces user to not back to form1 unless finishing work on form2

Get the value of form2's textbox
c# Syntax (Toggle Plain Text) 
  1. string str = form2.textbox2.Text;

Set properties in the form2, and then retrieve them when form1 becomes active again.

Its displaying blank values for entered textboxes in Form2.
When Form2 will disappear after entering the values, then how it will load the textbox values in Form1?
What we need to add in Form2?

Please suggest me for this.

Thanks a lot,
Anjali.....

I get this:

private void button2_Click(object sender, EventArgs e)
        {
            Form3 form3 = new Form3(); form3.ShowDialog();
            string str = Form3.textBox1.Text;
        }
It tells me that "Mail.Form3.textBox1 Is inaccesable due to its pro tsction level."

PLEASE HELP!!!

Because you said "Form3.textBox1.Text" you're not accessing the variable of the form you just created... you're trying to access the class direct, change "Form3.textBox1" to "form3.textBox1"

c.v.burgess, you may need to set protection level of textbox to private or declare properties/functions to get its text. To change protection level, select the control and from properties window change the value of "Modifiers" from private to public.
