Sample : In Form 1 Load place the below code : private void Form1_Load(object sender EventArgs e) { Form2 form2 = new Form2(); form2.Owner = (Form)this; form2.Show(); } In form 2 button click place : private void button1_Click(object sender EventArgs e) { this.Owner.Controls.Find(textBox1 true).First().Text = Hello; } This way we are trying to assign value to a text box in form 1 from form 2 . Thanks Priyan

Ok you may ask : What the hell is this man doing? But that is my problem. It appears string does not contain definition for BeginUpdate Items EndUpdate I try this because your code passes textBox1.Text from form1 to form2 I want to pass textBox1.Text from form2 to form1 (by cliking a form2 button) Is there a way to fix this? Thanks
