将变量放入Gridview中的LinkBut​​ton的PostBackUrl中

Question

Can anyone tell me how to get this to work please? It is a LinkButton in a row in a Gridview (in an ItemTemplate)

<asp:LinkButton ID="lbOrder" runat="server" PostBackUrl='EditOrder.aspx?OrderID=<%# Eval("OrderID") %>' Text='<%# Eval("OrderID") %>'></asp:LinkButton>

It appears okay on screen. When I click it - the OrderID is not being passed.

On the EditOrder page the querystring looks like:

http://mysite/Orders/OrderID.aspx?OrderID=<%# Eval(\"OrderID\")%>

I have tried plenty of permutations of single inverted commas and double inverted commas - but I can't get the OrderID to appear in the queryString correctly.

Is a post-back really necessary? I suggest you to use asp:HyperLink instead.

<asp:LinkButton ID="lbOrder" runat="server" NavigateUrl='<%# String.Format("~/EditOrder.aspx?OrderID={0}", Eval("OrderID"))%>' Text='<%# Eval("OrderID") %>'></asp:LinkButton>
