1    I am trying to hide a tablerow based on the data of a querystring that is passed from the products.aspx to the productdetails.aspx.
2    I am using SQL Express, VB Syntax and ASP.NET 2.0
3    
4    
5    Here is how I am passing the querystring on the products.aspx page:
6    
7    <asp:HyperLinkField HeaderText="Details" Text="view details" DataNavigateUrlFields="Product_Number" 	DataNavigateUrlFormatString="productdetails.aspx?ID={0}" >
8    </asp:HyperLinkField>
9    
10   Here is the HTML on ProductDetails.aspx that is receiving the querystring information   
11   
12   
13   <asp:SqlDataSource ID="SqlDataSource1" runat="server"  
14               SelectCommand="SELECT * FROM [Products] WHERE (dbo.products.Product_Number = @Product_Number) AND (Product_Quantity > 0)" 	
15   ConnectionString="<%$ ConnectionStrings:MaxxReliefDatabaseConnectionString1 %>">
16               <SelectParameters>
17                   <asp:QueryStringParameter Name="Product_Number" QueryStringField="ID" />
18               </SelectParameters>
19   </asp:SqlDataSource>
20   <asp:FormView runat="server" ID="productdetail" DataSourceID="SqlDataSource1">
21       <ItemTemplate>
22            <div id="productdetails">
23            <table>
24               <tr>
25                   <td>    
26                       <table>
27                           <tr>
28                               <td>
29   		#<asp:Label ID="ProductNumber" runat="server" Text='<%# Bind("Product_Number") %>'></asp:Label></td>
30                           </tr>
31                           <tr>
32                               <td><h3>
33   		<asp:Label ID="ProductName" runat="server" Text='<%# Bind("Product_Name") %>'></asp:Label></h3></td>
34                           </tr>
35                           <tr>
36                               <td><asp:Label ID="ProductCategory" runat="server" Text='<%# Bind("Product_Category") %>'></asp:Label></td>
37                           </tr>
38   
39                           <tr>
40                            	<td>
41   		<asp:Label ID="Cost" runat="server" Text='<%# "$" & Eval("Product_Cost") %>'></asp:Label></td>
42                           </tr>
43                       </Table>
44                   </td>
45               </tr>
46           </table>
47           <table id="ProductInformationTable" runat="server">
48               <tr>
49   	<td>
50   	   Description: <asp:Label ID="ProductDescription" runat="server" Text='<%# Bind("Product_Description") %>'></asp:Label>
51   	</td>
52                 </tr>
53   <tr id="InstructionRow" runat="server" visible="true" >
54                   <td> Instructions: <asp:Label ID="ProductInstructions" runat="server" Text='<%# Bind("Product_Instructions") %>'></asp:Label>
55                   </td>
56               </tr>
57            </table>
58        </div>
59   </ItemTemplate>
60   </asp:FormView>
61   </asp:Content>
62   
63   So I need to know how to code for the ProductDetails.aspx.vb page. I am trying to hide the <tr> with the ID=”InstructionRow”  when the Value of the <label id= “ProductInstructions” querystring = “books” 
64   
65   SQL Database Information:
66   Products.dbo
67   ProductID
68   Product_Number
69   Product_Category
70   Product_Cost
71   Product_Description
72   Product_Instructions
73   Etc…
74   

I'd just wrap it in a panel, like this....

<asp:Panel id="HideMe" runat="server" visible="false">
     <tr><td>.....blah.....</td></tr>
</asp:Panel>

 I have never used a panel before so I just put it around the tr's and then what do I add for the coding so it knows when the category is books the visibility = false?

Its invalid syntax to  put panel inside table tags. means you are placing rows inside panel it's not valid place whole table inside panel

 This how I figured it out,

    Protected Sub formview1_Databound(ByVal sender As Object, ByVal e As System.EventArgs) Handles formview1.DataBound
        Dim InstructRow As HtmlTableRow = formview1.FindControl("HideTR")
        Dim categlbl As Label = DirectCast(formview1.FindControl("cat"), Label)

        If categlbl.Text = "Books" Then
            InstructRow.Visible = False
        End If

    End Sub
