Have Mdi Child change a label.text on Mdi Parent

Question

Hello: I would like to have something in the MDI Child change something in the MDI Parent. Can someone tell me of sample or where to look?

Suppose Parent form 1 Form1 and child Form is Form2 then write following in child form private void button1_Click( object sender { (( Form1 ) Application .OpenForms[ Form1 ]).Lable1.Text = Your Text  ; }

Hi Giorgio You can get the ParentForm from the MDI Child form and then either iterate through the controls collection and change the text of a label (for example) or you can set a property on the parent form which sets the label's Text. I have attached a sample for your reference.

Nainil: Thank much... I like the sample. Now I have to implement it into my projects. Karan: I tried your but it gave me an error. I will read up on your sample and try to make it work. Its always nice to have several ways of doing something. Thanks. Kirtan: I get an error also on yours. Its probably something that I am doing or missing. ??? Is it maybe that I am trying to change the text of a button on the Parent? (( FormICEPack ) Application .OpenForms[ FormICEPack ]).buttonGio.Text = Your Text  ; Anyways... All three of you gave me the basics to figure out my issue... Thanks all.

i think you are going to change label text in parent form....from you child form...so for this here is code. // write in child form private void button1_Click(object sender EventArgs e) { this.ParentForm.Controls[label1].Text=HI... }
