Basically value1 and value2 are two numbers from a database, when I click button1 I want to get the number in the code behind (c#) so I can add another number to it and the same for value2. I simply require the line needed in c# that will extract the Eval value.... Your help will be much appreciated.

```
<asp:Button ID="button1" runat="server" Text='Plus' OnClick="button1_Click"/> 
<asp:Label ID="value1" runat="server" Text=' <%# Eval("value1") %> ' /> 
<asp:Button ID="button2" runat="server" Text='Minus' OnClick="button2_Click" />  
<asp:Label ID="value" runat="server" Text=' <%# Eval("value2") %> '/> 

```
