Like History box in this picture

can anyone help me!!

p/s: English is not my native English so can have some errors

Answer 1

mdiChildForm. BringToFront() should fix the issue.

Answer 2

You could try use mdiChildForm.Activate();

which is equivilant to:

this.TopMost = true;
this.Focus();
this.BringToFront();
this.TopMost = false;

Answer 3

That doesn't look like a MDI application...

At any rate, the "History" box in that image is a " Tool Window ". Set its FormBorderStyle() property to "FixedToolWindow", its ShowInTaskBar() property to false, and set its Opacity() property to 70 or 80.

Then display it by passing in the "owner" like this:

    private void MainMdiForm_Load(object sender, EventArgs e)
    {
        History hist = new History();
        hist.Show(this);
    }
