How to use Button, LinkButton, and ImageButton in ASP.NET?

In ASP.NET, Button, LinkButton, and ImageButton are commonly used controls for triggering specific operations or events. Their usage is as follows:

1. Button control:
   The Button control is used to trigger server-side events. In an ASPX file, the following syntax can be used to add a Button control:

<asp:Button ID="btnSubmit" runat="server" Text="Submit" OnClick="btnSubmit_Click" />

Event handling procedures can be written in the Code Behind file.

protected void btnSubmit_Click(object sender, EventArgs e)
{
    // 处理点击事件的逻辑
}

1. LinkButton control:
   The LinkButton control is a hyperlink button that can also trigger server-side events. In ASPX files, you can add the LinkButton control using the following syntax:

<asp:LinkButton ID="lnkSubmit" runat="server" Text="Submit" OnClick="lnkSubmit_Click" />

Event handling procedures can be written in the Code Behind file.

protected void lnkSubmit_Click(object sender, EventArgs e)
{
    // 处理点击事件的逻辑
}

1. ImageButton control:
   The ImageButton control is an image button that can also trigger server-side events. In an ASPX file, you can add the ImageButton control using the following syntax:

<asp:ImageButton ID="imgSubmit" runat="server" ImageUrl="~/Images/submit.png" OnClick="imgSubmit_Click" />

You can write event handlers in the Code Behind file.

protected void imgSubmit_Click(object sender, ImageClickEventArgs e)
{
    // 处理点击事件的逻辑
}

The examples above demonstrate how to use Button, LinkButton, and ImageButton controls in ASP.NET, and how to add click event handlers to them. These controls can have styles, events, and logic added to them as needed to achieve rich interactive effects.
