如果按下 html 按钮，如何在页面后面执行 C# 代码？

Question

my current code (that doesn't do anything):

if (Request.Form["delete"] != null)

and the delete button is generated in the C# behind the page:

public string delete = ""; //in the public partial class

delete += " <button name=\"delete\"/>Delete</button>";

once I click the button - nothing happens, how can I change the if (or the delete which is the button) so that after I press the button the code will execute?

for example:

when I press the button, a message will appear...

if (Request.Form["delete"] != null)
{
Response.Write("inside the if");
}

side note:

I've tried using this code

Button clickedButton = sender as Button;

    if (clickedButton.ID == "delete")

and it didn't work as well.

Answer 1

if (Request.Form["delete"] != null)
    {

and put your button in a form .

the form :

<form name="form_name" action="your_page.aspx" method="post" >
<input type="submit" name="delete" value="delete"/>
</form>

the problem? my button wasn't a submit button. you HAVE to use type=submit on it so that after it's clicked, it will actually "go to" the form .
