In my MDI application i have changed the size of its MDI client to avoid the scrollbars that appear when a portion of an MDI child form is moved out of the view of the client area of the MDI parent form (i made the MDI client size bigger than the size of the screen).
I know i can use an API using ShowScrollBar to hide these scrollBars but it flickers and i prefere not to use an API.
Now i have a problem that when minimizing any of the MDI child Forms its location is set by default to the bottom of the MDI client (which its size is bigger than the size of the screen) so the minimized MDI child form doesn't appear.
So how can i change the location of a minimized mdichild form?
Thanks in advance.
Try to read the ClientRectangle from the parent and apply the location to the child accordingly before minimizing. I think you ca implement the Form Minimized or minimizing events.

I have a MDI Parent Form 1 and an MDI Child Form 2
The Form 2 has a MinimumSize = new System.Drawing.Size(568, 453); set.
And as long as the MDI Child is not maximized everything works fine(the MDI Parent shows scrollbars).
As soon as I maximize the MDI Child, the scrollbars disappear and i cannot access the rest of the Controls on the Form 2 in the lower Right Corner(the MDI Parent doesnt show Scrollbars).
I couldn't find any solution for this problem, i would be glad for any help or pointers. I would even be open for an other approach.
The MDI parent never shows scroll bars if the MDI children are maximized, as then technically no MDI child leaves the MDI client area (either no or all MDI children are maximized).
If you need automatic scrolling for maximized MDI children, you need to configure your MDI children to perform auto scrolling, too.
my question is that there are any ways to drag / show mdi child form in the another monitors. i want to drag child form and show it in another monitors.
The whole idea of MDI is that MDI children are contained within the parent.
If you want to show one form on screen A and another form on screen B, then you need to stay away from mdi app.
So the answer to your question is no, can not be done.
I have an MDI application with child windows. It's possible for the user to move the child window's title bar up high enough so that it is placed underneath the toolbar for the application, and the control box for the window is obscured, making it impossible to close. There is sometimes so little room to "grab" the window and pull it back down that the user has to restart the application altogether. How can I limit the positioning of an MDI child window so that it stops when it bumps up against the bottom of the MDI parent's toolbar?
If that's too confusing, here's the simplified version: how can I constrain the movement of an MDI child form to a certain portion of the screen or parent form?
Register to the MDI child's Move event and make sure that the Top is greater than 0.
By the way, when I move a MDI child too high, I get a scrollbar letting me scroll up.
Hi i am stuck in MDIform with panel control.
I have one panel control Docked (fill) to parent MDI form. When i try opening new child form with menu click event the child form doesn't show up in MDI container.
After debugging few times, i set the visible property of panel control to false, the child form shows up now.
what is causing this? is there any way that i can leave panel control as docked (fill) inside MDI container form and show the child form on top of that panel?
MDI child windows are always shown as a child of the MDI client area. The dark gray window in an MDI parent. You cannot cover this up with a docked panel, the child windows will show behind the panel. Obviously not visible. You must leave room for the client area, a hard requirement.
After the call to the Show method for the MDI child form, add the childForm.BringToFront() statement. The child form will show in front of the parent form controls.
It might be, that the panel control is shown in front of the MDI child. Try to move the MDI child to the foreground or the panel to the background.
I have a form which is a mdicontainer and has a menu strip at the top. I add a child form to my mdi container and when I maximize the child it maximizes over the menustrip. I want to know how to limit the child to maximize below the menustrip. Any help would be appreciated.
Your child form is being maximized in the way that child forms are supposed to be maximized in MDI. It's not really covering the menu strip of the parent form - it's actually merging its own menu strip with that of the parent form.
To make the child form take up only the available child area in the MDI parent (and not merge its menu with the parent's menu), put something like this code in the child form's Resize event:
if (this.WindowState == FormWindowState.Maximized)
{
this.WindowState = FormWindowState.Normal;
this.Size = this.MdiParent.ClientSize;
this.Location = new Point(0, 0);
}
which will prevent the child window from being actually maximized.
I say "something like this code" because this snippet doesn't work exactly right. The ClientSize property of the parent form gives the overall size of the form, whereas you want to use the size of just the MDI client area. I don't know how to get that, and apparently it's not super-easy. See this question:
Size/Location of Winforms MDI Client Area
You could set the MaximumSize property so that it doesn't fill up the entire container.
I know this an old question, but I just ran into this on an old project I'm working on, so here's an answer for anyone seeing this. Setting the Dock to DockStyle.Fill will give you the behaviour you want.
Just be aware that the window will act/look strange if you try to reposition or resize the window while it has that DockStyle.
To accomplish this, I subscribed to the MDI client window's resize event and if the window had just been maximized, I set its DockStyle to Fill, set the FormBorderStlye to FixedDialog(to prevent resizing), and set the window state to normal to prevent the maximization from occurring.
To prevent the user from moving the window while it is in this "maximized state" I simply overrode the WndProc method and handled when the window was being moved(SC_MOVE) and placed a return to prevent the action from taking effect.
