Since this is the web you have to first decide if you want to change the label's text with a postback or without a postback. With a postback means you can do it in C# but it's also easy to do without a postback in JavaScript.

c# - in the button click event

C#

label1.Text = "SomeText";

javascript - onclick function of the button

JavaScript

function SomeButtonClick(){
document.getElementById("label1").value = "SomeText";
}
