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.

<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
