Hello,
When a form2 is shown with showdialog  it disables the form1.
How can I disable the form but enable 3 buttons on form1.

Cheers

Are you trying to show a msgbox or a form? Are you using Win Forms or WPF?

for a msgbox you cannot show it modeless. You could create a new Thread and show the msgbox in that thread.  You would then need to "block" usage of form2 but form1 would be usable.

Otherwise if you have a form then Form.Show will make it modeless.

Here are some examples of Modal and Modaless

You will have to make make sure the the whole form is enabled (meaning there is nothing modal affecting it) and then disable everything on the form except the 3 buttons.

There may be other ways of doing what you want.

You need to use
form2.Show

Open in new window

There is no ready made way of doing this. You will have to do it yourself.

1. To enable only 3 buttons on a form you must DISABLE all other controls.
2. If your form1 is blocked by calling showdialog then you cannot call it.
3. use Show, disable form2 and disable everything on form1 except your 3 buttons.

NUmber 3 is maybe not the best solution but it is the best based on your limited information so far.
