LinkButton to set url parameter

I have a form with two panels. The first has a set of five link buttons. Each when clicked needs to set a URL parameter that can be read by the second panel when clicked. This will be a parameter value in the object data source for a data grid on the second panel. This is probably very easy but it is eluding me at this time. Thanks for your help

I think this should get you started. Simply let the OnClick event set a hidden field that is used as a parameter in the ObjectDataSource.
<asp:LinkButton id="Link1" runat="server" OnClick="Link1_Click" Text="My Link 1"/>
<asp:HiddenField id="ParameterVal1" runat="server" visible="false" /> <!-- visible="false" will only show this field in the encrypted viewstate and will help prevent hack attempts -->
 
 
protected void Link1_Click()
{
     ParameterVal1.Value = "SomeValue";
}
