one Click event for multiple buttons with Text property

Question

I want to make a click event for a bunch of buttons. The problem is that I want to use the button's Text, and pass it to a function. Now the click event is passed a object sender. When I tried changing that to Button sender, it gave errors. But I don't know how else I can work with the senders Text.

Here is the normal code, which gave a single error:

private void guess_Click(object sender, EventArgs e)
{
     guess(sender.Text);
}

I changed it to this, which gave errors:

private void guess_Click(Button sender, EventArgs e)
{
     guess(sender.Text);
}

Question: How can I work with the Button's Text property within this click event, which is a single click_event for multiple buttons?

Answer 1

Step 1: You need to subscribe to the Button Click event of all your buttons to the same EventHandler. so that button click on all your Buttons will fire the same `Event Handler.

Step 2: You need to cast the object sender into Button and then access its Text property to get the Button Text.

Try This:

button1.Click += new System.EventHandler(MyButtonClick);
button2.Click += new System.EventHandler(MyButtonClick);
button3.Click += new System.EventHandler(MyButtonClick);

private void MyButtonClick(object sender, EventArgs e)
{
  Button btnClick =  (Button)sender ;
  guess(btnClick.Text);
}
