Gustavo

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?

Accepted answer
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 ";

        }

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.

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.

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..."
}
