Question

I have a flowlayoutpanel, and I’m adding a user specifcied number of custom controls to it at runtime. What I want to do is detect when the flowlayoutpanel’s children lose or change focus.

So, in other words, how can I tell when one child control loses focus? I need to be able to see this at the flowlayoutpanel’s form, so I can do some calculations.

Answer 1

private void flowLayoutPanel1_ControlAdded(object sender, ControlEventArgs e)
{
    e.Control.LostFocus += new EventHandler(Control_LostFocus);
}

void Control_LostFocus(object sender, EventArgs e)
{
    Control c = (Control)sender;
    //some code you want write for controls that lost focus
}
