I have an MDIChild that has a toolstrip. When I open the window the toolstrip is displayed alongside the toolstrip of the MDIParent. The searching I have done suggests that this is normal behaviour unless the child is opened modally. Can I not stop this from happening and fix the toolstrip to the window it is meant to be displayed on?
This is the MDI Parent
This is the MDI Child
This is what happens when I open the child and what I want to stop happening.
Set the AllowMerge Property of the MenuStrip of the Child form to false.
From MSDN
Use the AllowMerge property to enable multiple-document interface (MDI) children to combine their respective menus in the MDI parent.
When this property is set the true, the menus will combine (just like in your case). When false, they won't

When I click maximize in control box on child form, control box buttons are disappearing. How can I prevent that? I want to show that control box part like when I do this :
"Form1.Dock = DockStyle.Fill"
Example:
Take a look at the XtraForm.AllowMdiBar property that control whether an MDI bar is allowed for this form:
P.S. This property is in effect for a parent MDI form, when the title bar skinning feature is enabled.
P.P.S. See also the Remarks section.
I am using an MDI form in which I have given option tool strip menu item as a call to a new child form. On the child form I have some buttons and DataGridView. But when I click the child form option the buttons and DataGridView are not displaying correctly. Provided I have already set the isMdiContainer property to true of MDI form.
The scenario runs successfully when I simply show a form, but the problem occurs when I use the form as a child form. Here is the code which I wrote in a tool strip menu item click:
frm_bank_master myfrm = new frm_bank_master();
myfrm.MdiParent =this;
myfrm.Show();
I got a strange problem. My mdi child form has 2 close buttons and 2 maximized buttons.
A screenshot of the problem:
I create the mdi child like this:
summaryForm.MdiParent = ContainerForm;
summaryForm.WindowState = FormWindowState.Maximized;
summaryForm.Show();
If I get rid of "summaryForm.WindowState = FormWindowState.Maximized;", the window style is correct. But I hope to make the mdi child form maximized when created.
It's a bug in Winforms. This will happen when the child is created by the parent's constructor. Move it to the Load event.
try this:
childform.ControlBox = false;
I've had so much luck developing my application... until now.
My application's main form is a MDI parent, and I didn't think of adding any MDI children in my tests until tonight.
To my surprise, the MDI parent seems to never "get focus" now. The Focus event and the OnFocus method are never called! I mean... it appears focused but none of the in-code focusing events/methods work. Instead a MDI child reports the focus.
How do I fix this?
This is by design. A form acts as a container for other windows, controls. The controls get the focus, the user interacts with, say, a button or text box. Only when the form doesn't have any controls will it get the focus, only because there's nothing else that can get it. The same thing will happen with the MDI child form as soon as you put a control on it. Or with a Panel or UserControl, other container control types.
A form has the Activate and Deactivate events. ActiveForm tells you with one is currently active. Note the distinction between active and focused.
i'd like the following code to work (where this. is a MDI child form)
this.HelpButton = true;
this.HelpButtonClicked += HandleHelpButtonClicked;
this.Refresh();
this code is being called after the mdi child form is displayed.
I wonder if i need to find some way of redrawing the title bar?

From the MSDN docs:
The value of the HelpButton property is ignored if the Maximize or Minimize buttons are shown.
