In the radgrid Itemtemplate how to use if else in the Preprocessor directives .Following code im using <%#eval("user-id)%> ,i need a check if user_id is null then #eval(secondcolumnid) so i used
<ItemTemplate>
                                                    <a href="Userinfo.aspx?User_Id=<%if(#Eval("User_Id")!=null){#Eval("User_Id")} %>">edit</a> <%#Eval("Last_Name") %>,
                                                    <%#Eval("First_Name") %>
                                                </ItemTemplate>
If i use like this it throws me an error Preprocessor directives must appear as the first non-whitespace character on a line .
So what is the best way to solve this solution.

<telerik:RadGrid ID="Grd1" runat="server" AutoGenerateColumns="False" AllowPaging="True">

<MasterTableView DataKeyNames="userid" CellSpacing="1">

<Columns>

<telerik:GridClientSelectColumn ButtonType="PushButton" />

<telerik:GridTemplateColumn HeaderText="Manager">

<ItemTemplate>

<a href="userinfo.aspx?User_Id=<%#Eval("User_Id") %>">edit</a> <%#Eval("Last_Name") %>,<%#Eval("First_Name") %>

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

<ClientSettings Selecting-AllowRowSelect="true">

<Selecting AllowRowSelect="True" />

</ClientSettings>

</telerik:RadGrid>
