HtmlInputSubmit Class

Note: This class is new in the .NET Framework version 2.0.

Allows programmatic access to the HTML <input type= submit> element on the server.

Namespace: System.Web.UI.HtmlControls
Assembly: System.Web (in system.web.dll)

'Declaration
Public Class HtmlInputSubmit
	Inherits HtmlInputButton
	Implements IPostBackEventHandler
'Usage
Dim instance As HtmlInputSubmit

public class HtmlInputSubmit extends HtmlInputButton implements IPostBackEventHandler
public class HtmlInputSubmit extends HtmlInputButton implements IPostBackEventHandler

The HtmlInputSubmit class is derived from the HtmlInputButton class and is used to create a button control on a Web page that submits a form. The HtmlInputSubmit control is often used with the HtmlInputReset control, which resets form controls to their initial values.

For a list of initial property values for an instance of HtmlInputSubmit, see the HtmlInputSubmit constructor.

The following code example demonstrates how to use the <input type=submit> HTML control declaratively on a Web Forms page.

The following code example demonstrates how to add the same HTML control programmatically during a call to the Page_Load method.

<%@ Page Language="VB" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">

  Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
    
    If (IsPostBack) Then
      ' Add code to process the Login.
    End If

  End Sub

  Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs)
    
    Dim userText As HtmlInputText = New HtmlInputText
    userText.MaxLength = 20
    Placeholder1.Controls.Add(userText)

    Dim passwordText As HtmlInputPassword = New HtmlInputPassword
    passwordText.MaxLength = 20
    Placeholder2.Controls.Add(passwordText)

    Dim submitButton As HtmlInputSubmit = New HtmlInputSubmit
    submitButton.Value = "Submit"
    Placeholder3.Controls.Add(submitButton)

  End Sub
</script>

<html xmlns="http://www.w3.org/1999/xhtml" >
