Hi,
Not sure what are you fighting with...
You can just delay second form creation till the button click
from1button_Click()

{

  if(this.form2 == null)

    this.form2 = new Form2(this);
 

  this.form2.Show(this);

}

Open in new window

In the Form1 Load, you need to add code to show Form2:

Form2 frm2 = new Form2();
frm2.Show();

zverjuga:
My Form2 has a treeview and a recursive function, it takes about 1 minute to load the Form2 on my PDA (it is a little bit long and this is samrt device application).  Therefore, I want to load the two forms together at first and hide Form2, when we need it, click a button to show it.  It save some time to wait for Form2 to load.

digital:
Where should I put the following code? I put this code in the public Form1(), and then try to show Form2 from Button1_Click, but it doesn't recognize the frm2 there.

public Form1()
{
Form2 frm2 = new Form2(this);
frm2.Hide();
}


public void Button1_Click(object sender, EventArgs e)
{
frm2.show();             <---- It doesn't recoganize frm2 here.
}

Hi,
I would not recommend populating the whole the tree view at once, especially for PDA screen as you cannot see it all anyway.
I would have initial tree view with all nodes except root collapsed, then populate a tree node as user opens it.
Also I noticed that form object creation takes most time for my forms (not the Show() method), so if this is the case for you then you can create Form object during system Idle time and call Show once object is done.

You would need to make frm2 a variable for the class to be able to access it in both the page load and the button click.
