    I have an radtext box as a field in a list box. I am not sure how I go about getting that field to update. After the user fills in the field, what could I use to trigger the update?

    See screen show of what it looks like

    <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="ReviewFormProjects.aspx.cs" Inherits="Helpers.RFP" %>
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

        <style type="text/css">
         /* The default display: inline needs to be overrided to resize the container to hold with the content */
         div.RadListBox .rlbTemplate

    Hello Najid,

    Thank you for contacting Telerik Support.

    In general the RadListBox does not support automatic database update when templates are used.
    In your case you can use TextChanged event of the RadTextBox control (make sure that AutoPostBack is set  to true). In the event  handler function you can update your database.

    I will be glad to assist you further.

    Best wishes,
    Peter Filipov
