The code I found on this board does not work, any idea why ?

It returns the error,

An unhandled exception of type 'System.NullReferenceException' occurred in System.Windows.Forms.dll

at line ,

if(f.GetValue(((Control)SourceControl).Parent).Equals(SourceControl))
        return f.Name;

The object I pass to it is a textbox from a pageframe.

-------------------------------------------------------------------------------------------
public static string GetControlName(object SourceControl)
{
FieldInfo[] fi = ((Control)SourceControl).Parent.GetType().GetFields(BindingFlags.NonPublic | BindingFlags.Instance |
BindingFlags.Public | BindingFlags.IgnoreCase);

foreach(FieldInfo f in fi)
{
        if(f.GetValue(((Control)SourceControl).Parent).Equals(SourceControl))
        return f.Name;
}

return null;
}
