b) button.AddEventHandler(Button_Clicked);
c) button.OnClick(Button_Clicked);
d) button.Subscribe(Button_Clicked);

Answer 1

To add a click event handler in C# code-behind, use the syntax 'button.Click += Button_Clicked;' This subscribes the method 'Button_Clicked' as an event handler to the button's Click event, which will be triggered when the button is clicked.

Step-by-step explanation:

To add a click event handler in C# code-behind, you would typically use the following syntax:

button.Click += new EventHandler(Button_Clicked);

or simply:

button.Click += Button_Clicked;

Here is a step-by-step explanation of how to wire up a button click event in C#:

First, you have the button control in your user interface that you want to respond to click events.

Next, in your code-behind file, you create a method that matches the signature of a button click event handler. This usually looks like:

private void Button_Clicked(object sender, EventArgs e) { // Your code here }

Finally, you associate this method with the button click event by adding it as an event handler:

button.Click += Button_Clicked;

This subscribes the 'Button_Clicked' method to the button's Click event, and whenever the button is clicked, the 'Button_Clicked' method will be called.
