You can add a form to a tab page by setting its TopLevel property to false and then using Controls.Add in the normal way.

I think our Forms were hosted on a Panel inside the TabPage, try that.

TabPage tab1 = tabCtrl.TabPages["TabName"];

Form.TopLevel = false;
Form.FormBorderStyle = FormBorderStyle.None;

Form.Parent = tab1;
Form.Visible = true; // this is what most solutions on other web sites lacked

tab1.Controls.Add(Form);
