hi,

I  have  3 tables in my database  1.Prouct(ProductId,Productname)

                                                2.Problems(ProductId,PoblemID,ProblemDesc)

                                                3. Solutions(ProblemId,Solutiondesc)

Now in my first page I have to display all the Productnames in a gridview with hyperlink to each product name.

On clicking  th productname i should pass the product id of the product to second page.

In second page i should display the problems relateds to product id 1 and so.
In the gridview i Used Hyperlinkfield.Now how do i Pass the product id  of the product to second page during the navigation?

 
 

Assuming you already have your datatable binded to your gridview, instead of using hyperlink, try this...

<asp:TemplateField HeaderText="Product Id">
    <ItemTemplate>
 <a href="page2.aspx?prod_id=<%# DataBinder.Eval(Container.DataItem, "ProductId") %>">
     <asp:Label ID="lblProductId" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "ProductId") %>'></asp:Label></a></ItemTemplate>
</asp:TemplateField>

Here, i'm passing the product id through the querystring. in your page 2, just add:

String strProdId = Request.QueryString["prod_id"].ToString()

 hi,
