Request for info on MDI about windowsribbon HOT 7 CLOSED

Hi Roland,
I think the problem is the code
newMDIChild.WindowState = FormWindowState.Maximized;
You should use this code instead
Size s = new Size(this.ClientSize.Width - 8, this.ClientSize.Height - _ribbon.Height - 8); newMDIChild.Size = s;
Your MDI Child should not have a Maximimized Button

Hi,

Thanks for coming back to me. Using your code did improve a little, but when clicking on Home tab page it appeared again.

When resizing the ribbon, the issue disappeared. But came back after clicking any of the tab pages.

Behavior:

1. Once project started, no visible issues
2. No issues when I drag it to another monitor
3. Clicking between the second and third tab page will resolve the view, but clicking File makes the issue comes back
4. Minimizing and maximizing the ribbon will solve the issue as well

Weird thing is that it only occurs whenever I click the File tab page.

Hi,

I think you do maximize the mdi form in an event. Only if I do this in a test, I can reproduce your view.

Hi again,

I reproduced the steps exactly as you suggested and yes, no issues... But... but, but, but...

How can I make the MDI child maximized upon load?

from windowsribbon.

Mdi is not supported by the Ribbon directly. see: Mdi support.
This is the answer of a Microsoft member.
But you can calculate a size for the MDI client without maximizing every time when the main form changes the size.
Or you don't use Mdi. Alternatively, you can use a TabControl with some effort for closing, hiding, ....

Shame, but ok... will use that instead... Thanks anyway for trying.

I have updated the Wiki (News and Hints) with some words for MDI support
