Question

I am displaying a list of accounts objects in a repeater. Each object contains three fields namely studentID, studentName and studentAge. I have wrapped it with a link button. As a result the each individual item which is displayed is clickable. I have also added a click handler to the link button. The problem is that how am I supposed to know which student was clicked? Because originally I want to navigate to the next page and display that particular student’s details. Once I know which student is clicked then I can store his details in a session object and then navigate to the new page and get it back.

Thanks for your help.

Answer 1

In your case, it would be better to use a normal hyperlink, pass the ID as query string, and have the new page get the details.

<asp:HyperLink runat="server" 
               NavigateUrl='<%# Eval("studentID", "StudentDetails.aspx?id={0}") %>'
               Text="Details" />

Update:

To get the studentID on the same page, use the ItemCommand event instead and have the LinkButton as follows:

<asp:LinkButton runat="server"
                CommandName="StudentDetails"
                CommandArgument='<%# Eval("studentID") %>' />

The studentID will be stored into the CommandArgument property, which value will be passed to the ItemCommand event handler.
