Use of Repeater asp.net with datatable Jquery

I'm new to ASP.NET techonology and I'm trying to use datatable Jquery with a repeater.
But it doesn't work with the value inside the table. It work with just the head (see below). These data come from a database.
<asp:Repeater ID="Repeater1" runat="server" DataSourceID="Model2">
<HeaderTemplate>
<table id="table_id">
<thead>
<tr>
<th>Nom</th>
<th>ip</th>
<th>askit</th>
</tr>
</thead>
</HeaderTemplate>
<ItemTemplate>
<tbody>
<tr>
<td><%# Eval("Li_Id")%></td>
<td><%# Eval("Li_ip")%> </td>
<td><%# Eval("Li_nom_askit")%> </td>
</tr>
</tbody>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>
And here it's what I get
Screen of what I have
So for example the line with id '594' is not in the datable that I have create.
I try to use a ListView but it doesn't work.
Does anybody know why ?
Thanks

You're creating a separate tbody around each row. Move the opening tbody tag to the end of the header template and the closing tbody tag to the beginning of the footer template.
(I'm assuming you're referring to the datatables.net jQuery plugin.)

How to get Dynamic Span id in jquery?

Iam using jquery in asp.net
I have one user control in which i have div and in div table and in table tr and in tr td and in td i have lables.
ASCX :
<div ID="Container" runat="server" class="dvContainer">
<table ID="Table" class = "Tablecs">
<thead><tr>
<td colspan="2">
<asp:Label ID="lbl1" Text="Swiss" runat="server" /></td>
</tr>
</thead>
<tr>
<td>ABC</td>
<td>DEF</td>
</tr>
<tr>
<td><asp:Label ID="lblPA" Text="SUN 12/21 05:04" runat="server" /></td>
<td ><asp:Label ID="lblPD" Text="SUN 12/21 19:00" runat="server" /></td>
</tr>
<tr>
<td><asp:Label ID="lblAA" Text="SUN 12/21 05:04" runat="server" /></td>
<td ><asp:Label ID="lblAD" Text="SUN 12/21 19:00" runat="server" /></td>
</tr>
</table>
i want to bind data dynamically to these user control. i.e., binding data to lables in user contol.
my Jquery
$div.find(".Table").text(oPorts[iCount].Name); // my result is an array of oPorts and i have filed as Name
But this is not working fine.
when i checked into code dynamically its generating SPAN for each and every lable
How to find that SPAN id dynamiccaly in a loop and bind data to lables??
Any help is appreciated. Thanks in Advance.

suppose you have a usercontrol with a markup like given below
<%# Control Language="C#" AutoEventWireup="true"
CodeBehind="WebUserControl1.ascx.cs" Inherits="DOTNET_FORMS.WebUserControl1" %>
<div id="Container" runat="server" class="dvContainer">
<table id="Table" class="Tablecs">
<tr>
<td>
<asp:Label ID="lblPA" Text="SUN 12/21 05:04" runat="server" />
</td>
<td>
<asp:Label ID="lblPD" Text="SUN 12/21 19:00" runat="server" />
</td>
</tr>
</table>
</div>
and you have registered this usercontrol on your .aspx page like this:
<%# Register TagPrefix="UC" TagName="Test" Src="~/WebUserControl1.ascx" %>
and used it like this:
<UC:Test ID="uc1" runat="server" />
then, when you run your page, your elements get rendered something like
<div id="uc1_Container" class="dvContainer">
<table id="Table" class="Tablecs">
<tr>
<td>
<span id="uc1_lblPA">SUN 12/21 05:04</span>
</td>
<td>
<span id="uc1_lblPD">SUN 12/21 19:00</span>
</td>
</tr>
<tr>
<td>
<span id="uc1_lblAA">SUN 12/21 05:04</span>
</td>
<td>
<span id="uc1_lblAD">SUN 12/21 19:00</span>
</td>
</tr>
</table>
</div>
see how ids of your labels and other elements (elements with runat="server" attribute ) got changed i.e.
lblPA > uc1_lblPA
lblPD > uc1_lblPD
Container > uc1_Container
so, you have to look out for these changes, because only then you can grab these elements using jQuery, cause jQuery is a client side language, it executes, after the server side code (runat="server") has executed.
However, if you do not want to look out for modified id, you can do following
remove runat="server" attribute, and make sure your ids are unique, all of them
let the runat="server" attribute be their, place an attribute clientidmode="static" on all of your server side controls. and Ids wont change.
use ClientId i.e. in your jQuery selector, grab an element like this: $('#"+'<%= lblPA.ClientID %>');
now, since your IDs are unique, you don't need to find, directly grab the elements like this:
$('#lblPA').text();
or if you want to loop through all the tds of your table with class Tablecs, do this:
$('.Tablecs tr td').each(function(index, item){
alert($(item).text());
});

Error in table when adding runat=server

I have a html table in my ASPX page and would like to use it in code-behind for some processing. The table is shown as below:
<table class="hovertable" id="tblData">
<tr>
<th>ID:</th>
<td colspan="3" style="font-weight: bold">
<%= Eval("ID") %>
</td>
</tr>
<tr>
<th>Date:</th>
<td><%# Eval("Date", "{0:dd-MMM-yyyy}") %></td>
<th>Amount:</th>
<td><%# Eval("Amount", "{0:C}") %>
</tr>
</table>
However, when I add the runat="server" attribute to my table, I am produced with the following error:
CS1502: The best overloaded method match for 'System.Web.UI.HtmlControls.HtmlTableRowCollection.Add(System.Web.UI.HtmlControls.HtmlTableRow)' has some invalid arguments
Any ideas what may be wrong here? Am I missing out anything?

An html table (which is not a pure asp.net server control) can't contain asp.net server controls. Take a look at this answer:
http://forums.asp.net/t/1524580.aspx/1
In my opinion, you should ask yourself the following question?
Do i need to solve this client or server side?
if your answer is client, you should implement the update logic with Ajax, otherwise you could use the ASP.NET server control and implement it server side.

OK guys, I have solved this issue by myself. The problem causing it was because of a <td> not having the corresponding <tr> element.
It was something like below:
<table class="hovertable" id="tblData">
<tr>
<th>ID:</th>
<td colspan="3" style="font-weight: bold">
<%= Eval("ID") %>
</td>
</tr>
<tr>
<th>Date:</th>
<td><%# Eval("Date", "{0:dd-MMM-yyyy}") %></td>
<th>Amount:</th>
<td><%# Eval("Amount", "{0:C}") %>
</tr>
<td colspan='4'>
Some data....
</td>
</table>

I think you can use this for the same purpose
<asp:Table ID="Table1" runat="server">
</asp:Table>
What you are trying to do is adding runat="server" attribute to a HTML control

Try adding <asp:Labels> where you need to manipulate data.
<table>
<tr><td><asp:Label id="lblRow" runat="server" /></td></tr>
</table>
Table columns and rows cannot be accessed via code behind if you have runat="server" in the tag because they are pure html.
Another way is to use a StringBuilder to create the html table in the code-behind and and asp:LiteralControl to output the table.

Also if we remove the tbody element it will not throw error for td mismatch

Insert data into asp.net table through code

I have a table in asp.net page and i want to insert the data which will be recieved from service call through c# code behind. Any idea on how to do this.
Below is my table.
<table id="DataTable" class="style1">
<tr>
<td>
</td>
<td>
</td>
<td>
</td>
<td>
</td>
</tr>
</table>
I just need to insert values recieved from service call in place of &nbsp.

In your aspx page asp:Label controls and assign the values from code behind by accessing them using Id.
Inside .aspx
<asp:Label Id="lblName" runat="server">
In code behind
lblName.Text = "Value from Service";
If you need to repeat this table use GridView.

Use the asp:Table control instead.. It gives you much more control from server side than a normal html tag :)
And it ofc render as a normal table client side

If you persist on working with pure html table you can use an new/old style to control it.
like so:
<table>
<% foreach ( var o in objects ) { %>
<!--UserControl -->
<tr>
<td> can put here data like so: <%= o.Id %> </td>
</tr>
<!--UserControl -->
<%}%>
</table>
or you can use Repeater and Bind data if it's dynamic.
If data is not dynamic and your table will not grow or change size, you can use a little OOP for this.
like so:
create in your class properties and then populate them.
public string MyLabel { get; set; }
put something in page load.
in aspx do it like so..
<table>
<tr>
<td> <%= MyLabel %> </td>
</tr>
</table>
or
<table>
<tr>
<td> <asp:Label ID=|"myText" runat="server"/> </td>
</tr>
</table>

Make the table Html server side control. Try this:
<table runat="server" id="DataTable" class="style1">
<tr>
<td id="td1" runat="server">
</td>
<td id="td2" runat="server">
</td>
<td id="td3" runat="server">
</td>
<td id="td4" runat="server">
</td>
</tr>
Now in the code behind
td1.InnerText="xx" or td1.InnerHtml=..

Using asp.net in html pages

If I want to combine asp.net code with html (mark up) file, I need to open <% %> and execute teh code.
What If I want to iterate over a database with select query while feeding information and creating rows. For example:
<table>
<%
foreach(DataRow dr in dataset.Tables["empoloyees"].Rows)
{
%>
<tr>
<td>
<asp:Label runat="Server" Text="<% dr[FirstName].toString(); %>"/>
</td>
<td>
<asp:Label runat="Server" Text="<%dr[LastName].toString();%>"/>
</td>
</tr>
<%
}
%>
</table>
Is the syntax correct..and is that practice good (it is always used in php) ? or should I bind the data to the label somehow?(no idea how. but somehow)?

If you're trying to take a set of data and display it in a table then try using control like the GridView or the Repeater.

First and most important thing - do not mix business logic and data access functionality with the data representation markup!
Supposing you are using WebForms, you can use Repeater control which is bound in the code behind of a page/control (aspx.cs/ascx.cs) so View stay decoupled and just bound to specific properties of data source:
ASPX:
<asp:Repeater ID="employees" runat="server">
<HeaderTemplate>
<table>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td>
<asp:Label runat="Server"
Text="<%# DataBinder.Eval(Container.DataItem, "FirstName") %>"/>
</td>
<td>
<asp:Label runat="Server"
Text="<%# DataBinder.Eval(Container.DataItem, "LastName") %>"/>
</td>
</tr>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>
Code Behind: (Page_Load() for instance)
employees.DataSource = dataset.Tables["empoloyees"].Rows;
employees.DataBind();

I suggest using a Repeater control if you want a piece of markup to iterate over and bind to it.
<asp:Repeater id="Repeater1" runat="server">
<ItemTemplate>
<tr>
<td> <%# DataBinder.Eval(Container.DataItem, "FirstName") %> </td>
<td> <%# DataBinder.Eval(Container.DataItem, "LastName") %> </td>
</tr>
</ItemTemplate>
</asp:Repeater>
Alternatively, use a GridView, though I find that Repeater gives you more control over the emitted markup.

You are almost there. Try this:
<table>
<%
foreach(DataRow dr in dataset.Tables["empoloyees"].Rows)
{
%>
<tr>
<td>
<%= dr[FirstName].toString(); %>
</td>
<td>
<%= dr[LastName].toString();%>
</td>
</tr>
<%
}
%>
</table>

You should use a repeater instead something like this
<table>
<asp:Repeater runat="server" ID="userRepeater" >
<ItemTemplate>
<tr>
<td><%#DataBinder.Eval(Container.DataItem,"FirstName")%></td>
<td><%#DataBinder.Eval(Container.DataItem,"LastName")%></td>
</tr>
</ItemTemplate>
</asp:Repeater>
</table>
and in your codebehind
userRepeater.DataSource = dataset.Tables["empoloyees"];
userRepeater.DataBind();
for a list of all types of <% %> take a look here

You don't have to use <% %> at all. Just put your code in between tags with runat="server", and then go ahead and use standard ASP.NET tags (e.g. asp:TextBox runat="server"). Just make sure it's an *.aspx page.
FWIW, your question seems a little backwards to me. If you are creating *.aspx pages then you can just use standard HTML anywhere you want. If you are trying to somehow squish ASP.NET into an *.html page - then you are misunderstanding how ASP.NET works.
