Focus on Control of Child's Form

[khurram]

Hi All,
I am working on a windows form application and we have an MDI form
with Toolbar on it. On click event of toolbar we are creating a specific
instance of a child form and showing it. Now on the child form we want to
set the focus on the first field and for that purpose we set the tab order
as well as calling the control.Focus method at the end of form constructor
method.
For some reason the child forms first field does not get the focus. On
inspection we find out that the Main MDI form is getting the focus and then
the focus moves to the child form but the first field does not get the
focus. I think it has something to do with MDI behaviour. Does anybody have
any idea ?
FYI, I am using .Net infragistics windows control (Tool bar etc.) and
running Visual Studio 2003 on Windows XP.Any help would be greatly
appreciated.

Thanks,
Khurram

You didn't mention which field eventually got focus. However I believe you
are probably calling the control.focus too early if you do it in the ctor.
Try the form load event instead. As a last resort I'd try the Form.GotFocus
event if Form.Load wont do it for you. I've not done much MDI with .Net, but
I doubt its got anything to do with MDI. Have you got any other stuff going
on in the ctor that is maybe firing events you don't want?
