Passing Eval Through Command Argument in Listview - asp.net

Question

I have a link button that I am trying to pass a parameter through into the OnClick event handler. To do this I am using the CommandArgument field.
I have this link button within a listview so I am retireving the data using Eval, so I want to pass that value into the CommandArgument as such:
<asp:LinkButton id="BTN_ApproveTicket" runat="server" CommandArgument="<%#Eval("TicketNum").ToString()%>" OnClick="BTN_ApproveTicket_Click">
</asp:LinkButton>
I am doing this exact think with some table elements in my page, but this one is not working.
The error that I am getting is it is taking the <%#Eval("TicketNum").ToString() as a literal, so I am getting a server tag is not well formatted error. Any ideas on how to fix this would be greatly appreciated.
This is the AlternatingItemTemplate that is in question:
<AlternatingItemTemplate>
<td style="<%#setTicketClass(Eval("TicketNum").ToString(), Eval("UnitID").ToString(), Eval("TicketDate").ToString())%>" >
<asp:LinkButton id="BTN_ApproveTicket" runat="server" CommandArgument='<%#Eval("TicketNum").ToString()%>' OnClick="BTN_ApproveTicket_Click">
<i class="fa fa-check-square-o" style="<%#setCheckBoxClass(Eval("Approved").ToString())%>" ></i>
</asp:LinkButton>

It might have to do with quotes - you are using double quotes everywhere, which may confuse parser. Try replacing outer ones with single quote:
CommandArgument='<%#Eval("TicketNum").ToString()%>'
