Child Forms are those forms that are found inside another form (parent form). There are multiple ways to create child forms - most of them require to use a MDI Container.
Child Forms without MDI Container
I, personally, had lots of problems when I used it (parent form’s controls were going over the child form), so I decided to create child forms without involving a MDI Container. This method will let you solve the problem with the controls that go over child forms, by allowing you to use BringToFront().
The main trick here is to treat child forms as Controls. You’ll create a child form just like any other control. When you use this method, you have to set it’s TopLevel to false - otherwise it won’t work.
The following lines of code are used to create a child form:
1 2 3 4 5 6 7 8 9 Form childForm = new Form(); //initialize a child form childForm.TopLevel = false; //set its TopLevel to false Controls.Add(childForm); //and add it to the parent Form childForm.Show(); //finally display it childForm.BringToFront(); //use this to render your newly created form over the controls
