Controls in container form come over child form?

Question

In a container form I have menu and buttons to open ther forms.

Here I am fac

Answer 1

It appears as though that form is a sibling of those other child controls. Do you have to open it as a child of that window? Can't it be like a non-modal dialog box and not a child window of that main form?

If it has to be within that main form and a sibling of those controls, then you're going to have to set the Z-Order of it. There's no property for that, so you're going to have to look toward the Win32 API call, SetWindowPos:

[DllImport("user32.dll", EntryPoint = "SetWindowPos")]
public static extern bool SetWindowPos(
int hWnd, // window handle
int hWndInsertAfter, // placement-order handle
int X, // horizontal position
int Y, // vertical position
int cx, // width
int cy, // height
uint uFlags); // window positioning flags


const uint SWP_NOSIZE = 0x1;
const uint SWP_NOMOVE = 0x2;
const uint SWP_SHOWWINDOW = 0x40;
const uint SWP_NOACTIVATE = 0x10;

And call it something like this:

SetWindowPos((int)form.Handle,   // that form
             (int)insertAfter.Handle,  // some other control
             0, 0, 0, 0,
             SWP_NOMOVE | SWP_NOSIZE | SWP_SHOWWINDOW | SWP_NOACTIVATE);
