Add New Child Form to Parent MDI from Child Form

[Derek Price]

I have a tabbed MDI form that contains one form, say MyChildForm1. When MyChildForm1 is focused/active, I would like to launch another child form, say MyChildForm2 that gets added to the tabbed MDI form. Is there a recommended way of doing this?

Thanks in advance!

Hi Derek,

I feel like it is not a very usual way of approach. Could you please provide me an exact scenario you need and more details regarding this post? Then it will be convenient for us to work with.

Consider the VS.NET IDE. It opens with a start page with links to recently opened projects. If you click on one of those links, it opens that project and opens any previously opened files in new tabs. But it keeps the start page open.

Does this help?

Hi Derek, Thanks for the details. You should set the child form''s MDIParent to the main form as follows to achieve the behavior. private void buttonAdv1_Click(object sender, System.EventArgs e) { Form3 f1 = new Form3(); // Set the new form''s MDI parent to main form f1.MdiParent = (Form1)this.Parent.Parent; f1.Show(); } Please refer to the sample attached and let me know if this meets your requirements.

Thanks - that works great! I didn''t realize that there was a parent property until late last night! :)
