Get the ID of a Selected row in a Gridview

[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
