Examples

This example shows two ways to create the same form in MVC. The first way uses the Using statement. The second way uses the MvcForm class directly.

<%  Using (Html.BeginForm("ProcessForm", "Home"))%>

   Enter your name: <%= Html.TextBox("name") %>
   <input type="submit" value="Submit" />

<% End Using%>

<br /><br />

<% Dim form As Html.MvcForm = Html.BeginForm("ProcessForm", "Home")%>

       Enter your name: <%= Html.TextBox("name") %>
       <input type="submit" value="Submit" />

<% form.EndForm()%>

<% using (Html.BeginForm("ProcessForm", "Home"))
   { %>

   Enter your name: <%= Html.TextBox("name") %>
   <input type="submit" value="Submit" />

<% } %>

<br /><br />

<% MvcForm form = Html.BeginForm("ProcessForm", "Home"); %>

       Enter your name: <%= Html.TextBox("name") %>
       <input type="submit" value="Submit" />

<% form.EndForm(); %>
