C# – Child Form Size Set to the MDI Form’s MDI Container’s Size

cformsmdi

I'd like to know how I can have a child form load up with it's size covering the complete MDI Parent's MDI container space (the dark-gray thing)? Setting the child form's WindowState to Maximized is not an option as it'll maximize any other form too. Suggestions?

I think this code should do it:

Form childForm = new Form();
f.Left = 0;
f.Top = 0;
f.Size = ParentForm.ClientRectangle.Size;

.net – Problem with icon on creating new maximized MDI child form in .NET

A slight modification to Calanus' solution:

    private void MdiBase_Load(object sender, EventArgs e)
    {
        // Fixes bug where loading form maximised in MDI window shows incorrect icon.
        this.Icon = Icon.Clone() as Icon;
    }

This allows you to set the icon at design time (just as you would for other forms), and does not need any hard-coded file or resource accessing.

Delphi MDI – handling open/close/activate child form

I wrote a Taskbar type of component a bunch of years ago that does just this type of thing. It's called TrmMDITaskbar. You can find a copy of it on Torrys, it's a part of the rmControls library package. It handles activation, minimizing, maximizing etc.

The gist of how it works is that it hooks the MDIParents window handle looking for MDIChild events and does stuff based on those events.

If you're looking to write your own I would suggest that as a good place to start.

P.S. The version on Torrys is a little older but should still work. I do have a newer version available on my support website. (Mills Enterprise)
