I have label controls and textbox controls in the details page to which clicked GridView row data will be displayed, but when I click on a GridView row, it redirects the GridView row data to details page but in the details page it does not display the record of the GridView row data of the previous page, on the details page.
Here is my HTML and code
<asp:ScriptManager runat="server" />
<asp:UpdatePanel runat="server" ID="paneltemp">
<ContentTemplate>
<asp:GridView ID="GridView1" runat="server" GridLines="None" AllowPaging="true" HeaderStyle-ForeColor="#eeeeee" HeaderStyle-Font-Bold="true" HeaderStyle-BackColor="#224f6d"
AutoGenerateColumns="false" OnSelectedIndexChanged="OnSelectedIndexChanged" OnPageIndexChanging="OnPageIndexChanging" OnRowDataBound="OnRowDataBound" class="table" Width="100%"
HeaderStyle-HorizontalAlign="left" RowStyle-HorizontalAlign="Left">
<Columns>
<asp:BoundField DataField="ContactName" HeaderText="Contact Name" />
<asp:BoundField DataField="City" HeaderText="City" ReadOnly="true" />
<asp:BoundField DataField="Country" HeaderText="Country" />
</Columns>
</asp:GridView>
