Question

I have a main window and a toolstrip on it with different command buttons. In these commands, I’ve a ‘Print’ button too (See Below). When I click on ‘Print’ button , I need to show sub-form as Modal Less Dialog. Because, I’ve few option on sub-form. If user select them then he/she can interact with Main Form too.

Meanwhile, on show() method I disable all controls on Main Form (see below) as it will be done if I use ShowDialog() method to show sub-form. When I click the Print Button, it’s color changed which shows it is focused/selected.

On click sub-form is show like below pic.

Logically, it should return to previous mode when I close sub-form. But, even sub-form is showing… that ‘Print’ button on Main-Form is still focused/selected. When I close the sub-form, that ‘Print’ Button still focused/selected like below.

What Event/ Property needs to be changed to make this ‘Print’ Button to show like as it is in initial state.

I’ve tried Invalidate(), change BackColor but didn’t meet the requirement yet. Any Guidelines ?

Well, Selected Property in ToolStripButton is read only. Anyone, needs to clear the selection of toolstrip buttons can use below method which is invoked via reflections.

MethodInfo method = typeof(ToolStrip).GetMethod("ClearAllSelections", BindingFlags.NonPublic | BindingFlags.Instance);
            method.Invoke(yourToolStripName, null);
