Hello,

When a window is closed, what is the next window to get activated, and how
is that determined?

Thanks,

Schneider
 
Hi Schneider,

When a window is opened, Windows tracks its position in the Z order.
Generally, the currently activated window is positioned at the top of the Z
order. If this window is close, Windows seeks the next window positioned in
the Z order and activate it.

Hope this helps.
If you have any question, please feel free to let me know.

Sincerely,

Thats not what I'm seeing.

The problem I'm having is, When a specific form is closed, a different form
steals to focus.

Example:

Visual zorder:

Form A
Form B
Form C


Form c gets closed and Form A gets activated, when I want Form B to be on
top.

Form B, C are not modal.

Is there a way to stop Form C from causing the activation of Form A?

Thanks,

Schneider
 
Hi Schneider,

Thank you for your reply!

In your example, I consider this behavior would happen only in the case
that you set the TopMost property of Form B to true and after you show Form
C, you activate Form A and then activate Form C again.
Is there a way to stop Form C from causing the activation of Form A?
Click to expand...

It's Windows that tracks and determines which form would be activated next.
In the above case, to prevent the activation of Form A after Form C is
closed, a workaround is to set Form A as the owner of Form B and set Form B
as the owner of Form C. Handle the Activated event of Form A and Form B and
activate its owned form in the event handler.

The following is the code in Form A.
public partial class FormA : Form
{
public FormA()
{
InitializeComponent();
this.Activated += new EventHandler(FormA_Activated);
}

void FormA_Activated(object sender, EventArgs e)
{
if (this.OwnedForms.Length > 0)
{
this.OwnedForms[0].Activate();
}
}
private void button1_Click(object sender, EventArgs e)
{
FormB frm = new FormB();
frm.Owner = this;
frm.Show();
}
}

Hope this is what you want.
If you have any question, please feel free to let me know.
