[vuyiswam]

Good Day All

I have a Grid defined like this

<asp:GridView ID="GrdOrdersinProcess" runat="server" 
                                       AutoGenerateColumns="False" BackColor="White" BorderColor="#3366CC" 
                                       BorderStyle="None" BorderWidth="1px" DataKeyNames="OrderID" CellPadding="4" 
                                       DataSourceID="SqlDataSource1" 
                             
                         
                                        >
                                       <RowStyle BackColor="White" ForeColor="#003399" />
                                       <Columns>
                                           <asp:TemplateField HeaderText="Order No">
                                               <ItemTemplate>
                                                   <asp:Label ID="lblOrderID" runat="server" Text='<%# Eval("OrderID")%>'></asp:Label>
                                               </ItemTemplate>
                                           </asp:TemplateField>
                                           <asp:TemplateField HeaderText="Order Amount">
                                               <ItemTemplate>
                                                   <asp:Label ID="lblOrderAmount" runat="server" Text='<%# Eval("OrderAmount")%>'></asp:Label>
                                               </ItemTemplate>
                                           </asp:TemplateField>
                                           <asp:TemplateField HeaderText="Order Date">
                                               <ItemTemplate>
                                                   <asp:Label ID="lblOrderDateTime" runat="server" 
                                                       Text='<%# Eval("OrderDateTime")%>'></asp:Label>
                                               </ItemTemplate>
                                           </asp:TemplateField>
                                           <asp:TemplateField>
                                               <ItemTemplate>
                                                   <asp:LinkButton ID="lbkProcess" runat="server" OnClick="lbkProcess_Click" 
                                                       Text="Process">
                             </asp:LinkButton>
                                               </ItemTemplate>
                                           </asp:TemplateField>
                                       </Columns>
                                       <FooterStyle BackColor="#99CCCC" ForeColor="#003399" />
                                       <PagerStyle BackColor="#99CCCC" ForeColor="#003399" HorizontalAlign="Left" />
                                       <SelectedRowStyle BackColor="#009999" Font-Bold="True" ForeColor="#CCFF99" />
                                       <HeaderStyle BackColor="#003399" Font-Bold="True" ForeColor="#CCCCFF" />
                                   </asp:GridView>

and now as you can see i have a link Button and i have its handler. Before i used to have a Check box and i could find with row has been selected, but now my style is different , i want to get value of "lblOrderID" for the selected record. I dont use a Checkbox to get the selected item because i dont allow multi select into functionality.

How can i get that on the server or client side.

Thanks
