Determining the Active Control

[Joe Hanna]

Hi Everyone,

Just wondering how you can determine the Active Control on a form in the absence of the ActiveControl Member from .NET CF Forms?

Tried Google, but there was nothing on .NET CF.

Thanks in advance,
Joe

You're going to have to loop through the controls, starting with the main
Form, checking the Focused property to see which control has focus. Adding
the following property and helper method to your Form should do what you
want:

public virtual Control ActiveControl
{
get
{
return GetFocusedControl(this);
}
set
{
if (!value.Focused)
{
value.Focus();
}
}
}

private Control GetFocusedControl(Control parent)
{
if (parent.Focused)
{
return parent;
}
foreach (Control ctrl in parent.Controls)
{
Control temp = GetFocusedControl(ctrl);
if (temp != null)
{
return temp;
}
}
return null;
}
