Question

I have the following problem:

I open multiple modal forms in a stack (for example, form1 opens modal form form2 which in turn opens modal form form3, etc.). I would like to hide the entire stack.

I tried calling the Hide method or setting the Visible property on the parent, but this only hides the parent. I also tried hiding every form individually, but then I have to call ShowDialog on each of the forms which locks the thread in which I call the aforementioned method.

Is there be a way to set the modal dialogs so that they inherit the status of the parent and get hidden in a cascade just by setting the property on the first form?

I’m also open to other suggestions.

Answer 1

To re-show a form you hid by setting obj.Visible = false just set obj.Visible = true, not ShowDialog.

ShowDialog initiates a message loop, which will cause confusion since the dialog is already running a message loop.
