Temporarily hide modal dialog

Question

I have a modal dialog displayed with the main application window set as the owner (as in dialog.ShowDialog(mainAppWindow)), and I would like to temporarily allow the user to interact with the main application window before returning to the modal dialog again.

How can i do this? I am using Windows Forms.

Edit: AutoCAD does it well.

Answer 1

Just close the modal dialog. This is not like regular Form instances, so you just push it back by calling ShowDialog () again. Note that calling Hide () in a modal dialog box also closes it.

Answer 2

Then I don’t think you want a modal dialogue ...

The whole purpose of a modal dialogue is that the user cannot do anything until he gets rid of it in any way. I think you should just create your own form class to act the way you would like.

void ShowDialog()
{
  var dialog = new MyModalForm();
  dialog.NeedInteraction += (sender, eventArgs) =>
  {
    dialog.Hide();
    Enabled = true;

    //wait till user finishes working with main window

    Enabled = false;
    dialog.Show();
  }

  Enabled = false;
  dialog.ShowDialog();
  Enabled = true; //don't forget to make it enabled afterwards
}

This may not be a clean solution (since you do not need to hide the modal dialog), but it works, at least for my situation.
