Change MDIChild buttom text from MDI Parent

set the modifiers property of child form 's control  to public and than
use code like this:
FrmChild frm = new FrmChild ();
frm .txtBox.Text = OK";
frm .Show();
 

Hello Giorgio,

On your child form declare a Button ButtonChild as public before the initializeComponent()  then in form load assign the ButtonChild to the button you want access to.

eg ButtonChild = BtnSave

You now have ALL properties etc available to you from any form...


In your mdi when you instantiate a new form you simply change the text of the public button ButtonChild and BtnSave will have the text of ButtonChild since they are one and the same.

I hope you understand what I mean.

Form1 f = new Form1();
f.ButtonChild.Text = "&Save";
f.Show();

Cant't get any simpler...

// In mdi parent form's button click

// here f1 is a child form instance.

private void button1_Click(object sender, EventArgs e)

{


Form1 f1 = new Form1();


f1.Controls["button1"].Text = "hello world";


f1.ShowDialog();

}

Hi Giorgio,
         You can probably expose a property on your MDI child form which sets the Label's Text. Just before you call Show() on a MDIChild, you can set the property of the MDI child which set's the lablel's Text. I have attached a sample for your reference.

yes giorgio,we can do
before doing a showdialog,you call a function in child form from parent form supplying arguments..assign button text to supplied argument under the function in child form...
