How to Handle Click Events for Dynamically Created Buttons in ASP.NET?

ASP.NET dynamic button event handling

In ASP.NET, it is often necessary to dynamically create buttons at runtime. To handle events for these dynamic buttons, a slightly different approach is required.

Event handling of dynamic buttons

To attach a click event to a dynamically created button in C# ASP.NET, follow these steps:

1. Create Button Instance: Create a new Button instance.
2. Assign an event handler: Use the Click event handler to define the code that will be executed when the button is clicked. This can be done using lambda expressions or by creating a separate event handler function.
3. Add button to container: Add button to the desired container on the page.

Sample code:

<code class="language-csharp">Button button = new Button();
button.Click += (s, e) => { /* 您的代码在此处 */ };
// 或
// button.Click += new EventHandler(button_Click);
container.Controls.Add(button);

//protected void button_Click (object sender, EventArgs e) { /* 您的代码在此处 */ }</code>

By following these steps, you can dynamically create buttons and handle their click events in ASP.NET. This approach allows for greater flexibility and adaptability when creating interactive web pages.
