Hi all,

In my project I have a MDI_Parent form where I can show several MDI_Child.

When opening any Child_Form it is running well but when closing the one at the front, only the MDI_Parent appears and the Child_Form titles appear with the boxes minimize , maximize and Exit.

On maximize box click the child form appears but with errors in design.

that's my code when showing the form at the beginning.

Child_Form Child = new Child_Form();
Child.MdiParent = this;
Child.Show();

Please can anyone help me ?

Thanks in advance.
:)

You can start by making sure any third party your child form uses are installed.
Try to open the form in design mode and post the error that occurs here and maybe someone can help you.

I am sure there will be more help available if you were to post some of the code.

Hard to know what is going on without it, but are you calling the forms correctly? Are there any DLLs attached to the form? Where is the Focus?

More information = More Help.

Each child form appear very clear when trying to show it, there isn't any problem here .
My problem is when opening more than one child and closing the one at the front , the mdi parent only appears and the other child form is not appearing only ribbon which include the title and the minimize,maximize and close boxes of the child form is still there.

I think you are using like follow:

At an event of a control of MDI use follow:

child ch=new child();
 ch.MdiParent = this;
ch.Show();

First you should have a Form, enable it's IsMdiContainer=true.
child is a normal form.

I found the solution by assigning the Start position property of the child form to "center parent"
