MDI child form is shown behind TableLayoutPanel control
===

I have a borderless MDI Form witch fit screen size, I have placed on it 1 centered fixed size TableLayoutPanel control with 2 rows, at the top row (10%) I've placed a horizontal RibbonBar control, at the bottom row (90%) I placed a split container with 2 panels: the Left panel is used to host a vertical RibbonBar control and the right side is left to show child forms.
When I click to show the required child form, it loads behind the TabelLayoutPanel, I can see only a small part of it and cannot bring it to front.

I have tried to change FormBorderstyle property of both Parent and childs, also TopMost property of the childs. The issue remains the same.

Is someone having an idea on this matter, or maybe is there a better solution to layout The MDI Form ?

Thank you in advance.
