Question

i want to make the edit button visible for only those users who has the same user id as the data extracted from database. for this I'm using repeater and I'v extracted data using repeater but when i compare the user log in value and data from database inside repeater,i don't get the value inside button.can anyone help please. here's my code;

<asp:LinkButton ID="lbtnDelete" runat="server" CommandName="delete" 
  CommandArgument='<%# DataBinder.Eval(Container.DataItem, "id") %>' 
  OnClick="lbtnDelete_Click" Visible='<%# lLoggedUser.Text == DataBinder.Eval(Container.DataItem, "user_id") %>'>Edit</asp:LinkButton>

here lLoggedUser is login user id and "user_id" is id of user in database. But the value of lUserLogged get null.

Answer 1

Compare it to the data you bind to LoggedUser , not the value of LoggedUser itself. Like

Visible='<%# Eval("user_id").ToString() == Session["user_id"].ToString() %>

or

Visible='<%# Eval("user_id") == MyUserIDVariable %>
