ASP.NET - C# LinkButton Sender.Attributes Not Working

I am generating a list of people.  I am using the link button to allow a user to click on a person to get info on that person and continue processing on another page.

I have the below code on my .NET page
 <asp:LinkButton ID="lbPerson" runat="server" OnClick="selectPerson" 
                                EmpID='<%# DataBinder.Eval(Container, "DataItem.emp_id")%>' 
                                FirstName='<%#DataBinder.Eval(Container, "dataItem.ins_first") %>' 
                                LastName='<%#DataBinder.Eval(Container, "dataItem.ins_last") %>' >
                                <%#DataBinder.Eval(Container, "dataItem.ins_first") %>&nbsp<%#DataBinder.Eval(Container, "dataItem.ins_last") %>

Open in new window

I have the below code in my code behind page

    protected void selectPerson(object sender, EventArgs e)

        LinkButton _sender = (LinkButton)sender;
        string firstName = _sender.Attributes["FirstName"].ToString();
        string lastName = _sender.Attributes["LastName"].ToString();
        int empID = Convert.ToInt32(_sender.Attributes["EmpID"].ToString());

Open in new window

As I walk through the code all of the attributes are "NULL".  i have used this same code in numerous applications and I do not see why it's not working here.  Any ideas?

you can do it in different way like passing parameters to same function like:

<asp:LinkButton ID="lbPerson" runat="server" 
  OnClick="selectPerson('<%# Eval("DataItem.emp_id")%>', '<%#Eval("dataItem.ins_first") %>', '<%#Eval("dataItem.ins_last") %>')" >
<%#Eval("dataItem.ins_first") %>&nbsp<%#Eval("dataItem.ins_last") %>

Open in new window

and in code behind function is:

protected void selectPerson(object empid, object fname, object lname)


Open in new window

Hope this helps you.
