You just need to read the data from the database and put it onto the querystring. Maybe if you posted some relevant code we can be more specific.

Solution 2

Hi, Use datalist to show your product images, datalist have property that 'DataKeyField' set this property is equal to your ProductId, and use ItemCommand Event to go to the Product details page.

Solution 3

Its probably best to use UrlEncode[^] with your query string. This encodes the string during transmissions and protects from injection attacks.

Dear Pandya
It seems that you have problem in to fetch the data from database and forward it to the next page with the use of Query String
So for that purpose firstly bind your data in ListView(I am taking an example with the help of Eval)
Suppose From your requirement There is and product id(From DB) Which you want to take with your page
So

ASP.NET

<asp:listview id="list" runat="server" groupitemcount="1" xmlns:asp="#unknown">
        EnableModelValidation="True">
    <emptydatatemplate>
        No Data Is Available Right Now
    </emptydatatemplate>
    <layouttemplate>
        <table>
            <tr runat="server" id="groupPlaceholder" />
        </table>
    </layouttemplate>
    <grouptemplate>
        <tr>
            <td runat="server" id="itemPlaceholder" />
        </tr>
    </grouptemplate>
    <itemtemplate>
       <tr>
            <td colspan="2">
                 <a href="Preview.aspx?articleid=<%# Eval(" product_id=") %>">
           <asp:label id="title" runat="server" text="<%# Eval("Title") %>" />
                     </a>
                </td>
           </tr>
           <tr>
           <td colspan="2">
          
    </td></tr></itemtemplate>
</asp:listview>

Do not forget to bind this list view in code behind
Hope You got the solution
