Can I have asp:Repeater inside asp:Table?

I want to create asp:Table where I can add rows using asp:Repeater like:
<asp:Table runat="server" ID="tblRepeater">
<asp:Repeater runat="server">
<ItemTemplate>
<asp:TableRow runat="server">
<asp:TableCell runat="server" Text=""></asp:TableCell>
<asp:TableCell runat="server" Text=""></asp:TableCell>
</asp:TableRow>
</ItemTemplate>
</asp:Repeater>
</asp:Table>
But when I try to do this It gives me error:
System.Web.UI.WebControls.TableRowCollection must have items of type 'System.Web.UI.WebControls.TableRow'.
'asp:Repeater' is of type 'System.Web.UI.WebControls.Repeater'.
Am I doing somethig wrong or it is impossible to use Repeater in Table?

I'm not sure if your example is slimmed down or represents your actual use case, but in this case you'd be better of using either a GridView which will generate a table structure based off of a given Data Source, or creating the <table> structure yourself and then placing a repeater inside it:
<table>
<asp:Repeater runat="server">
<ItemTemplate>
<tr>
<td><asp:TextBox runat="server" /></td>
<td><asp:TextBox runat="server" /></td>
</tr>
</ItemTemplate>
</asp:Repeater>
</table>

Display repeater data horizontally

In continuation to my last question, I was suggested to use Repeater for displaying data fetched from SQL Db in horizontal layout.
https://stackoverflow.com/questions/25447351/asp-net-c-sharp-customized-gridview/25458682#25458682
As per suggestion I implemented a repeater control. The data was displayed in horizontal layout but only second column fetched from the DB.
How to get the first column too:
<asp:Repeater ID="RepDetails" runat="server">
<HeaderTemplate>
<asp:Literal ID="litRowStart" runat="server"></asp:Literal>
<td>
<asp:Label ID="lblExpID" runat="server" Text='<%#Eval("Exp_ID") %>' Font-Bold="true" />
</td>
<asp:Literal ID="litRowEnd" runat="server"></asp:Literal>
</HeaderTemplate>
<ItemTemplate>
<asp:Literal ID="litRowStart1" runat="server"></asp:Literal>
<td>
<asp:Label ID="lblExpAmt" runat="server" Text='<%#Eval("Amt_Allocated") %>' Font-Bold="true" />
</td>
<asp:Literal ID="litRowEnd1" runat="server"></asp:Literal>
</ItemTemplate>
</asp:Repeater>

Create your repeater like this:
<table>
<tr>
<asp:Repeater ID="repTest" runat="server">
<ItemTemplate>
<td>
<div>
<b>
<%#Eval("NameofColumnYOuWantToShowAsHeader") %>
</b>
</div>
<div>
<%#Eval("YourColumnValue") %>
</div>
</td>
</ItemTemplate>
</asp:Repeater>
</tr>
</table>

Try this one using AlternateingItemTemplate:
<asp:Repeater ID="RepDetails" runat="server">
<ItemTemplate>
<td>
<asp:Literal ID="litRowStart" runat="server"></asp:Literal>
<asp:Label ID="lblExpID" runat="server" Text='<%#Eval("Exp_ID") %>' Font-Bold="true" />
<asp:Literal ID="litRowEnd" runat="server"></asp:Literal>
</td>
</ItemTemplate>
<AlternatingItemTemplate>
<td>
<asp:Literal ID="litRowStart1" runat="server"></asp:Literal>
<asp:Label ID="lblExpAmt" runat="server" Text='<%#Eval("Amt_Allocated") %>' Font-Bold="true" />
<asp:Literal ID="litRowEnd1" runat="server"></asp:Literal>
</td>
</AlternatingItemTemplate>
</asp:Repeater>
Assuming that you're getting 2 rows in your datasource.

sql Query to select three of each referenced id

I'm using a SqlDataSource to bring back data to be displayed in a drop down. The headers of each drop down is the brand and in the drop down I want three products of each brand to be brought back.
<asp:SqlDataSource ID="Categories" runat="server" ConnectionString="<%$ ConnectionStrings:Categories %>" SelectCommand="SELECT * FROM CATEGORY WHERE CategoryID <5"></asp:SqlDataSource>
<asp:ListView ID="ListView2" runat="server" DataSourceID="Categories">
<LayoutTemplate>
<ul>
<asp:PlaceHolder ID="itemPlaceHolder" runat="server"></asp:PlaceHolder>
</LayoutTemplate>
<ItemTemplate>
<asp:SqlDataSource ID="images" runat="server" ConnectionString="<%$ ConnectionStrings:Categories %>" SelectCommand="SELECT * FROM ITEM ORDER BY Category_ref"></asp:SqlDataSource>
<li id="<%# Eval("CategoryName") %>">
<%# Eval("CategoryName") %>
<div class="dropDown">
<div class="listItem">
<asp:ListView ID="listview3" runat="server" DataSourceID="images">
<LayoutTemplate>
<asp:PlaceHolder ID="itemPlaceHolder" runat="server"></asp:PlaceHolder>
</LayoutTemplate>
<ItemTemplate>
<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# Eval("ItemID","Product.aspx?id={0}") %>'>
<p class="<%# Eval("Category_ref", "brand{0}") %>">
<asp:Image ID="image" CssClass="dropImg" runat="server" ImageUrl='<%# Eval("PhotoPath", "images/products/{0}") %>' />
<br />
<span><%# Eval("ItemName") %></span>
<%# Eval("ItemID").ToString() %>
</p>
</asp:HyperLink>
</ItemTemplate>
</asp:ListView>
</div>
</div>
</li>
</ItemTemplate>
</asp:ListView>
That is my entire navigation with the brand names coming back from database as well as the product information.
The second SqlDataSource query is where I need to fix up so it only selects 3 product. If there is a fourth it will leave it out.

In SQL Server:
SELECT TOP 3 * FROM ITEM ORDER BY Category_ref
In MySQL:
SELECT * FROM ITEM ORDER BY Category_ref LIMIT 3
You should always specify your database of choice with your question, and reduce the problem to the essence (all that ASP code is irrelevant and just scares people from your question).

Displaying search results in a Website

I am working on a website where i need to search for items from database and display it in page.I am using Datalist for displaying all the items .Now i need to display all the items according to some category.For example if i search for a two-wheeler it may have many categories or manufacturer's.Now I want to display it separately according to the categories.I can use many datalist to do that,but it will slow down the site.Instead which control can i use to do this.I searched the web but got no idea.So please give me sugessions to go about it.Any sugessions will be appreciated.
Code:
<asp:DataList ID="Dlitems" runat="server" RepeatDirection="Horizontal" RepeatColumns="4"
CellPadding="0" CellSpacing="15">
<ItemTemplate>
<table>
<tr>
<td>
<asp:ImageButton ID="ImgbtnProductImage" CssClass="imgdisp" ImageUrl='<%# Eval("ImagePath") %>'
CommandArgument='<%#Eval("ProductCode") %>' runat="server" CommandName="cmdView" />
</td>
</tr>
<tr>
<td>
<table>
<tr>
<td width="20px"></td>
<td>
<img src="../Database/images/inr.jpg" alt="addtocart" />
<asp:Label ID="lblproductprice" runat="server" Text='<%# Eval("Price") %>' CssClass="lbl" />
</td>
<td>
<asp:ImageButton ID="imgbtnaddtocart" runat="server" Height="25px" Width="25px" ImageUrl="~/Database/images/addtocart.JPG"
ToolTip="Add to Cart" CommandArgument='<%#Eval("ProductCode")+","+ Eval("ProductName")+","+ Eval("ImagePath")+","+ Eval("Price")+","+ Eval("LongDescription") %>'
CommandName="addtocart" />
</td>
</tr>
</table>
</td>
</tr>
</table>
</ItemTemplate>
</asp:DataList>

You can take benefit of gridview.
Bind you gridview data.
And letter merge the rows.
For an example you can use the below link

How to display group data separately using DataList in ASP.NET?
http://aspnettuts.wordpress.com/2010/10/21/asp-net-repeater-group-recordsdata-delete-selected-rows/

You should go for a Repeater control.
Example on Repeater
<asp:Repeater runat="server" ID="Repeater1">
<ItemTemplate>
<asp:ImageButton ID="ImgbtnProductImage" CssClass="imgdisp" ImageUrl='<%# Eval("ImagePathForTwoWheeler")%> + <%# Eval("ImagePathForCategory") %>'
CommandArgument='<%#Eval("ProductCode") %>' runat="server" CommandName="cmdView" />
</ItemTemplate>
</asp:Repeater>

How to add paging capabilities to the Repeater control in ASP.Net?

I have an asp.net Repeater control .I have to display only 5 rows in the repeater. I searched about it in Google but most of the resources are talking about how to do it with DataSet. In my case, I am using SqlDataSource. So I can have paging in this Repeater control?
ASP.NET Code:
<asp:Repeater ID="Repeater3" runat="server" DataSourceID="SqlDataSource3">
<HeaderTemplate>
<div>
<table border="1">
<thead>
<tr>
<td colspan="3">
<center> <strong>Safety Quizzes Record</strong> </center>
</td>
</tr>
<tr>
<td>
<center> <strong>Quiz Title</strong> </center>
</td>
<td>
<center> <strong>Date & Time</strong> </center>
</td>
<td>
<center> <strong>Score</strong> </center>
</td>
</tr>
</thead>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td>
<p>
<%# Eval("Title") %>
</p>
</td>
<td>
<p>
<%# Eval("DateTimeComplete") %>
</p>
</td>
<td>
<p>
<%# Eval("Score") %>
</p>
</td>
</tr>
</ItemTemplate>
<FooterTemplate>
</table>
</div>
</FooterTemplate>
</asp:Repeater>
<asp:SqlDataSource ID="SqlDataSource3" runat="server"
ConnectionString="<%$ ConnectionStrings:testConnectionString %>" SelectCommand="SELECT dbo.Quiz.Title, dbo.UserQuiz.DateTimeComplete, dbo.UserQuiz.Score
FROM dbo.employee INNER JOIN
dbo.UserQuiz ON dbo.employee.Username = dbo.UserQuiz.Username INNER JOIN
dbo.Quiz ON dbo.UserQuiz.QuizID = dbo.Quiz.QuizID
WHERE (dbo.employee.Username = #Username)">
<SelectParameters>
<asp:Parameter Name="Username" />
</SelectParameters>
</asp:SqlDataSource>
UPDATE:
What I want is showing only 5 items in the Repeater and the others will be listed on the other pages of the Repeater. So how I can have Pagining with SqlDataSource as mentioned above.

The Repeater control does not support paging out-of-the-box.
You could however implement it but it would require you to manually code it.
I would like to recommend you to change the Repeater control for the ListView control
Differences:
Repeater. This control does not support paging, updating, inserting or deleting operations out-of-the-box, if you want these features you would need to manually code them.
ListView. This is the most flexible of all data-bound controls. It's based on templates like the Repeater and DataList controls. It does support CRUD operations automatically mapping the operations agains your data source control. It does support server paging, and you can customize pretty much everything
BTW, since you are using a SqlDataSource, you would have to manually add paging code to your queries or store procedures, you could change that behavior if you use a LinqDataSource or an EntityDataSource
This is a simplified ListView markup:
<asp:ListView runat="server" ID="lv"
DataSourceID="lds" DataKeyNames="emp_id"
EnableModelValidation="false"
EnablePersistedSelection="false"
>
<LayoutTemplate>
<br />
<br />
A static header
<div runat="server" id="itemPlaceHolder"></div>
<br />
<asp:DataPager runat="server" PageSize="4">
<Fields>
<asp:NextPreviousPagerField
ButtonType="Button"
ShowFirstPageButton="true"
ShowLastPageButton="true"
/>
</Fields>
</asp:DataPager>
</LayoutTemplate>
<ItemTemplate>
<div style="background-color:Gray">
First Name
<div><asp:Label runat="server" ID="lbl" Text='<%# Eval("fname") %>'></asp:Label></div>
<br />
<asp:GridView ID="GridView1" runat="server" DataSource='<%# Eval("Achivements") %>' />
<br />
<asp:LinkButton ID="LinkButton1" Text="Select" CommandName="Select" runat="server" />
<asp:LinkButton ID="LinkButton2" Text="Edit" CommandName="Edit" runat="server" />
<asp:LinkButton ID="LinkButton4" Text="Delete" CommandName="Delete" runat="server" />
</div>
</ItemTemplate>
<ItemSeparatorTemplate>
<hr />
</ItemSeparatorTemplate>
</asp:ListView>

Please use the PagedDataSource shown at link http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.pageddatasource.aspx
