You can try this:

In the form_closed event of form2, write:

Form1 frm1 = new Form1(); 
frm1.ShowDialog();

Hope this helps. :)

As the name suggests, this method is the handler of the "fictive" event Load. You should never call it directly!, it will mess-up things. Do you simply need to show another form? Instantiate form class and show instance? What you want to do makes no sense.

If you explain the purpose of it, you might get an advice on what to do.

I want when closed form2 submit my changes in form1 .
example : back color changes

Sorry, first this is not the purpose. Why do you want it? Are you saying in form2 the user edits some changes, and they are updated in form1? As the user editing or when the form2 confirmed and closed? Is it modal or not? Why not having a master-detail controls on one form; with detail hidden when not used?

Solution 2

If you have form1 as your main entry point for the program (i.e. it's always open as long as your program is running), you won't want to reshow the form1 form.

In uday's example above, this assumes you want to create a new instance and how form1.

Instead, I'd recommend making a public method on form1 that form2 calls when form2's formClosing event is triggered.

Put what you want to run in the public method.

Does this "jive" with your thinking?

No, I need change something in form1.loading form1 for submit my changes

jchoponis 26-Jun-11 21:53pm

I see... I would still argue you could just expose a public property in form1 that would hold your result from form2. What exactly are you passing back to form1? Can you provide a snippet of your project so I can comment?

Solution 4

I think this is what you want:

in from1 write this:

C#

public void Form1_Load(object sender, EventArgs e)
        {
            MessageBox.Show("hi");
        }

and in from2 write this:

C#

private void Form2_FormClosed(object sender, FormClosedEventArgs e)
{
    Form1 frm = new Form1();
    frm.Form1_Load(sender,e);

}

hope it helps :)

Eroro:Form1_load(object,System.eventArgs) is Inaccessible due to its protection level
