I think you need to set direction property for <asp:Parameter> under <UpdateParameter> section. for more information visit the below link :

Thanks for your help, I was missing
<asp:Parameter Name="EmployeeID" Type="Int32" /> , but also the validation control I had in the top search was not allowing my function to update!!!

#
Enter Employee Name&nbsp;&nbsp;
#
<asp:TextBox ID="txtName" runat="server"></asp:TextBox>
#
&nbsp;&nbsp;<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
#
ControlToValidate="txtName" ErrorMessage="* "></asp:RequiredFieldValidator>
#
&nbsp;&nbsp;
#
<asp:Button ID="Button1" runat="server" Text="Search" />
#
<br />
<asp:Button ID="Button1" runat="server" CausesValidation="false"  Text="Search" />
