Determining object sender name in click event

[Ian Ornstein]

I am coding a windows form. The form has several labels and I hoped to use
one click event because the processing to be done is very similar.

I just tried this:
void lblDayNoClick(object sender, System.EventArgs e)
{
MessageBox.Show(sender.ToString() );
}
and the result displayed in the MsgBox was
System.Windows.Form.Label, Text:13

How can I take the sender and determine the name of the object that
was clicked to cause this event?
I expect that since the actual object is sent, its properties should
be available.

If not, please suggest alternate approaches.

Thanks in advance,

You should be able to cast the sender to the Control class and access
properties for the object such as Name.

Okay, I was able to get the Name of the control that invoked the Click event by:
void lblDayNoClick(object sender, System.EventArgs e)
{
System.Windows.Forms.Control lblTmp;
// lblTmp = (Control)sender; // This works
lblTmp = (System.Windows.Forms.Label) sender; // This also works
MessageBox.Show(lblTmp.Name);

However, if I want to do something with the control other than show its
Name, I need some other construct. The following code shows that I can
access the collection.

foreach (Label lbl in panel2.Controls)
{
MessageBox.Show(lbl.Name);
}

But this code still doesn't compile.
Can someone Please give me some correct syntax that will allow me to
change the properties of the clicked label?
panel2.Controls(lblTmp).BorderStyle = None;
}
