According latest post in the thread, You actually need to pass the ClientId of your textbox into the validate method. And your method should be like
function Validate(txtClientId)
{
if (doucment.getElementById(txtClientId).value == "") {
alert("you must enter the List name");
return false;
}
}
and you can call the method on aspx page
Validate("<%=txtListname.ClientID %>")

I dont think that this is a issue.
Is your button, textbox are on the same content page?
One other way is, Register a javascript variable and assign the ClientId of textbox from Server side (C# code) and use that variable to get the ClientId of textbox in the validate method.

Since I am new to working on C# webforms 2010, I have the following questions to ask so I can understand what is occuring in the following code:
1. In the code listed below, what does the '|' mean in the line 'rowState | DataControlRowState.Edit'? In addition can you explain what is occuring in the line of code for <pre> 'row = base.CreateRow(rowIndex, dataSourceIndex, rowType, rowState | DataControlRowState.Edit);'
protected override GridViewRow CreateRow(int rowIndex, int dataSourceIndex, DataControlRowType rowType, DataControlRowState rowState)
{
GridViewRow row;
if (this.BulkEdit)
row = base.CreateRow(rowIndex, dataSourceIndex, rowType, rowState | DataControlRowState.Edit);
else
row = base.CreateRow(rowIndex, dataSourceIndex, rowType, rowState);
return row;
}</pre>
2. In the aspx file, I see the following Namespace="BulkEditGridView". Can you explain or point me to a reference show I can understand how the "BulkEditGridView" namespace is wired into making the webpage work?
<pre>
<%@ Page Title="" Language="C#" MasterPageFile="~/ModuleBase.master" AutoEventWireup="true" CodeBehind="Manage.aspx.cs" Inherits="Support.Manage"
<%@ Register Assembly="Support" Namespace="BulkEditGridView" TagPrefix="test" %> </pre>
3. When I step through the code, I see the following items being referred to in the .aspx file. Can you explain what is occurring?
<pre>
<ItemTemplate>
<asp:CheckBox ID="chkL" OnCheckedChanged="CheckRoleChanged" AutoPostBack="true"
Checked='<%# Convert.ToBoolean( Eval ("L")) %>' runat="server" />
</ItemTemplate
</pre>
The code is called from ' row = base.CreateRow(rowIndex, dataSourceIndex, rowType, rowState | DataControlRowState.Edit);' that was listed above.

It is a bitwise OR of the two values.

Are you asking about the pre tag or the function call to CreateRow?? I am assuming it is about the tag since the other code seems to be fairly self documenting.
pre tag explained here[^]
Namespaces and their explanations is something you can google and get all sorts of information.
google c# namespaces[^]
classy_dog wrote: I see the following items being referred to in the .aspx file
I am unclear what you mean by referred to?? That is a part of the gridview that you have defined in your code.
I don't mean to pry or sound rude but the level of your questions in consideration with the code you have written leads me to wonder if all this is for a code interview you are taking part in. It just seems odd that you have all this stuff created yet you know so very little about it.

The following is in response to the answers that you provided so far:
1. Thank you very much for your answer for the bitwise operator.
2. I did NOT wirte this code. This is code in another part of company website. I need to write similar code in a new webpage for the company. I was just promoted to this position in my company. There are no other programmers here.
3. I am trying to understand this code so I can write code were data connects to the formview control. When looking online, microsoft recommends using a datasource control to directly connect with a web form control. However a datasource control like linq to sql will not work for me. My data will come from 2 tables that are not related and what users select in several dropdownlist boxes.
Thus can you show me how to bind data to a formview control, where the data comes from several different locations?

sorry it just seemed so weird... 
ok so you have one control that you want bound to two different data sources?? sounds kind of crazy and my recommendation would be for your server code to pull the two pieces of information together into a single source that can be bound on your page.
are your two different tables in the same sql server??

I want to let you know that I appreciate your help!
The following explains what I am doing in the process:
1. There are two pages that I will explain (the page not mentioned is just a summary page)
The first page (which I already completed) is where the user selects company, several dates, and all applicable subcompanies. A row was inserted into the 'master' table. The user click the next button, and now the user is on the second webpage that I am working on.
2. On the second web page, I need to display the following on the formview or possibly a detailsview
control in the following different stages:
a. stage 1 is what was entered on the first webpage into the web control. I also need to display the organization name. I can get the previous page information from the row that was just inserted into the master table. However the organization name is not a column in the 'master' table. The organization name is a session varirable I can pass. However, I need to bind that 'organization name' to the web control somehow. This what I am looking for.
b. stage 2 the user is going to select a payment month and year from a dropdownlist control embedded in the detailview or formview control. At that point, values from a schedule due date table will populate more date fields in the webform control.
There are more stages, but they are not relevant right now.
**In answer to your question, yes the tables are on the same database server. However the two tables are on different namespaces in different datacontext objects.

if all (99%) of your information can come from that one table and all you need to do is to associate a session variable then do that. I am not sure if you are aware of this but you can embed session variable values into a page.
<p>
the value of my session variable variableName = <%=Session[variableName] %>
</p>
does that help??

All of your answers definitely help!
I do want to metnion the following:
1. The information comes from two tables and what the user enters.
2. can you bind a session variable to a detailviews control somehow before you call the databind method for the detailview control?
3. Can you accomplish what I am trying to do on one webpage or would you break the stages I listed previously to being generated on separate pages?

classy_dog wrote: 2. can you bind a session variable to a detailviews control somehow before you call the databind method for the detailview control?
Yes, you can bind a control whether it's a part of detailsview control or just on the form to a session variable.
<asp:Textbox runat='server' ID='txtBoxControl' Text='<%=Session[varname] %>' />
the code <%=Session[varname] > is run when the page is rendered and is being sent to the client browser.

One web page but it requires some 'magic'... =)
all of these separate web pages you are talking about can really be inside of their of own div and then you can stack them like a deck of cards by controlling the css display property. you can simplify your client side development with some jQuery which might make your world a little easier.
you have to remember though that each time you are going back to the server is a post and get operation. in my opinion you want to minimize these transactions as much as possible.

With the help of Jquery you can call code behind function somthing like this
HTML Part:
<script src="jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
function confirmSubmit() {
$.ajax({
url: '/WebSite2/Default.aspx/SecretFormula',
type: 'POST',
contentType: 'application/json',
data: '{}',
success: function(result) {
alert(result.d);
}
});
alert("I am in ");
}
</script>
</head>
<body onbeforeunload="confirmSubmit()">
<form id="form1" runat="server">
<asp:scriptmanager id="ScriptMgr" runat="server" enablepagemethods="true">
<asp:button id="Button1" runat="server" text="Button">
</form>
</body>
</html>
Code Behind Function:
<WebMethod(EnableSession:=True), ScriptMethod()> _
Public Shared Function SecretFormula() As Integer
Return 42
End Function

I am looking for addititonal references for how to bind data to a C# detailsview 2010 web form control. Some of the links I have located so far are the following:
http://www.learn-asp.net/asptutorials/DetailsView.aspx
http://www.asp.net/data-access/tutorials/using-templatefields-in-the-detailsview-control-cs.
A standard linq datasource control can be connected to the detailsview control in standard situations as listed above. For data that is loaded into the detailviews control, I need to add 2 dropdown list controls values, data from an excel spreadsheet, and data obtained from tables not in the production database. Thus in this case, I am looking for additional refernces on how to bind these other references to the detailsview control when data is first loaded into the control.

Problem: I want the "TextBoxOrgName.Text" of a detailview control to contain the organization name.
I am working on a C# asp.net 2010 webform application. In a detailview control I want to place the organization name into the cell called "TextBoxOrgName.Text". The problem is I do not have the 'organization name' in the LinqDataSource1 listed below. I want setup a new linq data source to obtain the organization name value value listed below or place the value from a session variable here. Can you tell me how I could accomplish this goal?
[^] <asp:DetailsView ID="DetailsView1" runat="server" Height="50px" Width="125px"
EnableModelValidation="True" GridLines="Both"
AutoGenerateRows="False" DataSourceID="LinqDataSource1" BorderStyle="Solid"
HorizontalAlign="Center">
<Fields>
<asp:TemplateField HeaderText="Organization Name" >
<ItemTemplate>
<asp:TextBox ID="TextBoxOrgName" runat="server" Text='' BorderStyle="None" ></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
</Fields>
</asp:DetailsView>[^]
Here are a few additional notes:
1. I know the best solution probably would be to bring in value in linqdataource1. However the organization name column is not part of the table that I want to update in the sql server 2008 r2 database. I am thinking linqdataource1 should only be the table I want updated from this particular webpage correct?
2. This is a data entry application and the user enters the organization name on the first webpage. The user clicks the next button from the first page and now we are on the second data entry page. I have the organization name available on the second page as a session varirable obtained from the first page

Please use the correct tags (<pre></pre>) around your code; I don't understand why you think [^] is correct?

I thought [^] as the samething as (<pre></pre>) to put around the code. In the future, I use will (<pre></pre>) to put around my code.
