How to add click handler to a button dynamically in Windows Phone?

Hello everyone….

This post is a simple example showing how to add eventHandlers to a button dynamically in windows phone or windows mobile.
We know programming for windows phone is done in C# or Visual Basic. Here I am going to explain in C#.

I assume that you have dragged a button control in your interface.
Then in the code do this

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Microsoft.Phone.Controls;

namespace Dynamic_Events
{
    public partial class MainPage : PhoneApplicationPage
    {
        // Constructor
        public MainPage()
        {
            InitializeComponent();
            addEventHandler();
        }

        void addEventHandler()
        {
            button1.Click += new RoutedEventHandler(button1_Click);
        }

        void button1_Click(object sender, RoutedEventArgs e)
        {
            MessageBox.Show("Button Clicked");
        }
    }
}

This is the line that adds the dynamic click handler to the button named “button1”.

button1.Click += new RoutedEventHandler(button1_Click);

Just type button1.Click” and hit two tabs and Visual Studio does the rest for you.
