accessing controls on another form

Here are two ways In both cases you have to declare a member of the second form in your main form so you can access the second one in your button Eventhandler protected Form2 secondForm = null; ------ Make the controls on the second form public so you can access them private void button1_Click(object sender, System.EventArgs e) { this.secondForm = new Form2(); this.secondForm.Show(); } private void button2_Click(object sender, System.EventArgs e) { if(this.secondForm != null) this.secondForm.button1.Visible = false; } I dont think this is good but depends on you to use it or not ------- Or add Properties for the second form like this public bool HideButton { set { this.button1.Visible = !value; } } and then call the property private void button2_Click(object sender, System.EventArgs e) { if(this.secondForm != null) this.secondForm.HideButton = true; } I#ve tried the second one, cause this is the better way i think, but the first 'll also work. prie
