In a TableLayoutPanel I need to maximize a panel by double-clicking on it. I mean it to become a one panel control and others get temporarily hidden. In this case, the table layout panel control gets a control which includes only one panel or shows only one panel which fills inside it. Then if the panel which is now maximize will be double-clicked again, the original table of panels appear again. Is there any straightforward way for this purpose? What can I do to manipulate it better?

What I have tried:

Now I manually remove controls from the TableLayoutPanel control and then recreate it after going to restore. But this method has side-effects which I need to avoid.
In the next try, I changed the code to:
private int _columnCount, _rowCount;

private void player_DoubleClicked(object sender, IDisplayable displayable)
{
    if (tableLayout.ColumnCount == 1 && tableLayout.RowCount == 1)
    {
        tableLayout.ColumnCount = _columnCount;
        tableLayout.RowCount = _rowCount;
        foreach (var ctrl in tableLayout.Controls)
        {
            var panel = ctrl as UserControl;
            if (ctrl != sender)
                panel.Visible = true;
        }
    }
    else
    {
        foreach (var ctrl in tableLayout.Controls)
        {
            var panel = ctrl as UserControl;
            if (ctrl != sender)
                panel.Visible = false;
        }
        _columnCount = tableLayout.ColumnCount;
        _rowCount = tableLayout.RowCount;
        tableLayout.RowCount = 1;
        tableLayout.ColumnCount = 1;
    }
}

it doesn't change size of panel which remains shown

Well you need also to add the code to resize it when making it visible.

i need a way not to change anything regard to visible panels. they get hidden and automatically exposed when i maximize one of them and restore it back.

Yes, using the visible property should achieve that. If you just change the size of a panel inside your window it will affect the size of all the other but not cover them up. You need to move the maximised panel so it covers all the other controls. Then when you close it or make it invisible the others will be shown again.

I updated the question. Please refer to the code. It works partially. When I double-click the panels in the first row, they get maximized, but when I click on the 2nd row panels, they expand in the second row. I don't know why they don't get maximized in the whole panel!

Sorry, I don't have an answer. Perhaps my experiences were using a simpler layout.

can't be simpler than a 2x2 layout ;D

True, but that has nothing to do with your issue.
