# ASP.NET AutoPostBack Property

Complete ListControl Control Reference

## Definition and Usage

The AutoPostBack property is used to set or return whether or not an automatic post back occurs when the user selects an item in a list control.

If this property is set to TRUE the automatic post back is enabled, otherwise FALSE. Default is FALSE.

## Syntax

<asp:SomeListControl AutoPostBack="TRUE|FALSE" runat="server"/>

## Example

The following example sets the AutoPostBack property to "True" for a RadioButtonList control:

<script runat="server">
Sub Change(obj As Object, e As EventArgs)
Response.Write("You selected " & rb1.SelectedItem.Text)
End Sub
</script>
<form runat=server>
<asp:RadioButtonList id="rb1" AutoPostBack="True"
runat="server" OnSelectedIndexChanged="Change">
<asp:ListItem Text="Item 1" />
<asp:ListItem Text="Item 2" />
</asp:RadioButtonList>
</form>
