It's been a mess to show a DialogBox at the center of its parent form. Here is a method to show a dialog.
I am positioning its parent to center but not able to center the DialogBox
private void OpenForm(Object point, Object height, Object width)
{
FormLoading frm = new FormLoading();
Point temp = (Point)point;
Point location = new Point(temp.X + (int)((int)width) / 2,
temp.Y + (int)((int)height) / 2);
frm.Location = location;
frm.ShowDialog();
}
private void btnView_Click(object sender, EventArgs e)
{
try
{
ThreadStart starter= delegate { OpenForm(currentScreenLocation,
this.Height, this.Width); };
Thread t = new Thread(starter);
t.Start();
////// Some functionality here...
t.Abort();
}
catch (Exception)
{
}
}
You might want to check the Form.StartPosition
property.
http://msdn.microsoft.com/en-us/library/system.windows.forms.form.startposition.aspx
something along the lines of:
private void OpenForm(Form parent)
{
FormLoading frm = new FormLoading();
frm.Parent = parent;
frm.StartPosition = FormStartPosition.CenterParent;
frm.ShowDialog();
}
This of course requires setting the form's parent.
form1.StartPosition = FormStartPosition.CenterScreen;
See http://msdn.microsoft.com/en-us/library/system.windows.forms.form.startposition(v=vs.110).aspx
if you are making a custom MessageBox,you can simply put this:
CenterToParent();
in your custom MessageBox formload()
method.
In addition, if you want to set up arbitrary location you can use this
FormLoading frm = new FormLoading();
Point location = new Point(300, 400);
frm.StartPosition = System.Windows.Forms.FormStartPosition.Manual;
frm.Location = location;
frm.ShowDialog();
