error loading hyperlink in usercontrol from web page

[Ramon]

I get this error when the page with this hyperlink control on datalist loads.
Can't seem to find the source of problem

CS0019: Operator '&' cannot be applied to operands of type 'string' and
'object'

<asp:HyperLink id="HyperLink1" runat="server" NavigateUrl='<%#
"../default.aspx?DepartmentID=" &amp; DataBinder.Eval(Container.DataItem,
"departmentID") & "&DepartmentIndex=" & Container.ItemIndex %>' Text='<%#
DataBinder.Eval(Container.DataItem, "Name") %>'
CssClass="DepartmentUnselected">

DataBinder.Eval() returns an object.

Try:

<asp:HyperLink id="HyperLink1" runat="server" NavigateUrl='<%#
"../default.aspx?DepartmentID=" &amp;
DataBinder.Eval(Container.DataItem, "departmentID").ToString() &
"&DepartmentIndex=" & Container.ItemIndex %>' Text='<%#
DataBinder.Eval(Container.DataItem, "Name") %>'
CssClass="DepartmentUnselected">

I just added the ToString() method to convert the object to a string.

Hi,

Try the following:

<asp:HyperLink id="HyperLink1" runat="server"
NavigateUrl='../default.aspx?DepartmentID=<%#DataBinder.Eval(Container.DataItem,
"departmentID")%>&DepartmentIndex=<%#Container.ItemIndex%>'
Text='<%#DataBinder.Eval(Container.DataItem, "Name") %>'
CssClass="DepartmentUnselected">Link</asp:HyperLink>
