I have two buttons on a messaging form. A "To" (who's going to get the
message) and "Cc" (who's going to get a copy). The user choose the names from
a listbox that popup when the "To" button is clicked. When the user click the
"Ok" button the name is moved to the "To" label.

If the user now wishes to CC someone how do I get the "ok" button to know
I've click the "CC" and not the "To" and to put the name on the "CC" label?

I tried switch statement but was not working

view plaincopy to clipboardprint?
string text = btnTo.text;
switch (text.trim())
{
case "To":
Do something
break;
case "Cc":
Do something
break;
default:
Label1 += "Please choose To.";
}

string text = btnTo.text;
switch (text.trim())
{
case "To":
Do something
break;
case "Cc":
Do something
break;
default:
Label1 += "Please choose To.";
} view plaincopy to clipboardprint?

Although Alexey's suggestion will work, its usage is not encouraged. A much
better method (IMO) is to use CommandButtons rather than ordinary Buttons
and specify their CommandName and/or CommandArgument properties.
CommandButtons were designed precisely for this sort of scenario.

So, you create three buttons, set their OnClick property to the same
server-side method, but specify different CommandName properties for each
button:
