Child windows open behind the main parent window

[alag20]

Hi All,

I am facing a weird problem when opening multiple windows in my C# Winform application.

In the application I have a parent window and multiple child windows which are opened as and when user interact with the main window.

For some weird reason the child window appear for an instance and disappear behind the parent application.

I tried all of the following but nothing works -

ChildForm.Show( );
ChildForm.Focus ();
ChildForm.Bring ToFront();
ChildForm.Activ ate();

I am calling these from parent window. My main application is MDI, however these child windows are not MDI child - they are seperate windows.

Can anyone please help on this?

Thanks!

Hello

If your parent form is MDI parent and childs are not MDI childs ,then when ever the focus moves out of the child form ,ultimately the forms which is active will be displayed .if you want to display some thing like only one child at a time then you can use ShowDialog() method instead of Show();

if your child forms are not MDI you may also get another problem ,like when you close the main Parent MDI form with child forms open ,then the child forms still remains open. better make child forms also MDIchilds or use ShowDialog();

Hi

Infact these child windows were MDI child of the main window. But the requirements changed and I had to make them separate windows.

Apart from that there can be multiple child windows open at the same time so that user can browse through them and do various operations. Hence ShowDialog() is not ideal solution.

Hello

if you want to open many forms at a time , i suggest if number of forms are less

then better use Tab control ,which may solve your problem,Tab control allow user to browse all the available Tabs, but it is feasible only for a limited number of forms.
