ASP.NET MVC ComboBox - AutoPostBack


You can automate the process of posting the page back to the server after an item is selected from the list, by using the AutoPostBack property. When it is set to true the end users don't need to click any button on the page to post the page to the server - the ComboBox will do it automatically.

Usually the AutoPostBack property is used alongside the SelectedIndexChanged server-side event, which allows you to handle the change event on the server. This event is used in this example too.
View - Aspx

    <% Html.Obout(new ComboBox("ComboBox1")
    {

View - Razor

    @Html.Obout(new ComboBox("ComboBox1")
    {   
        AutoPostBack = true
