    <p>I'm having some problems getting a javascript registered on the page so my textbox can fire it on onBlur. I have created a simple test page to demonstrate my problem. </p> <p>Here is the backend VB.Net</p> <pre><code>Public Class Test Inherits System.Web.UI.Page Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Dim scriptText As String = "" scriptText &amp;= "&lt;script language='javascript'&gt;" scriptText &amp;= "function DisplayBlurMessage(){alert('you clicked outside the textbox');}" scriptText &amp;= "&lt;/script&gt;" ClientScript.RegisterClientScriptBlock(Me.GetType(), _ "BlurScript", scriptText, False) End Sub End Class </code></pre> <p>Here is the FrontEnd .aspx file</p> <pre><code>&lt;%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Test.aspx.vb" Inherits="WebApplication1.Test" %&gt; &lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml" &gt; &lt;head&gt; &lt;title&gt;Test Page&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;h3&gt;Test Page&lt;/h3&gt; &lt;form id="form1" runat="server"&gt; &lt;asp:TextBox id="TextBox1" columns="54" Text="Click here then outside" runat="server" onBlur="DisplayBlurMessage();"/&gt; &lt;/form&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>When i view the page, clicking out of the textbox, the javascript debugger gives me an error because the javascript isn't defined in the source. </p> <p>I can however get it to work by putting the Page_Load sub in tags in the aspx file and then accessing the Attributes of the textbox directly. But this is not what I want. </p> <p>Basically for my final page, I am going to want to iterate through all the textbox's on the page and then give them all a onBlur and onFocus methods that use their id's.</p> <p>Is this possible? I dont see where I am going wrong.</p> <p>Please help :(</p>

    1. COI have a feeling its because its not actually being included on the aspx page, but must it always be?

    2. COYes, you still need to add Codebehind and Inherits in page header(aspx).

    3. COI know this sounds kind of basic - but if you view source, do you see your script in the code?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
