Get the front most control

I have an old system here, that loads user controls into a type of panel, then when a user clicks on a menu item, they find the control, then they call the BringToFront method on the control, making it the visible user control in the panel.

I need to know how to get the current Front control in the panel ?

kind regards

As Joe White mentioned in a comment, BringToFront changes the order of the elements in the Controls collection of a container. So if you do

container.Controls[0]

it will give you the topmost control in that ControlCollection.

I think you are looking for GetChildIndex, this will give you the value of the z-oder of the control. So you can test this value for each child control in the current form controls collections, then:

The control with an index value of zero is at the top of the z-order, and higher numbers are closer to the bottom.

Something like:

foreach (Control x in parent.Controls)
{
    if(parent.Controls.GetChildIndex(x) == 0)
    {
        //x is the front most control
    }
}
