}

You can use semicolon separated values in the CommandArgument property of lnkRowSelection. Let's say you want to pass values of emp_id, days_worked, total_absents, and days_marked, here's what you need to add in the aspx code:

<asp:LinkButton ID="LinkButton1" 
    runat="server" 
    Text='<% # Eval("FullEmpName") %>' 
    CausesValidation="false"
    CssClass="navigationlink" 
    CommandName='<% # Eval("FullEmpName") %>' 
    CommandArgument='<%#Eval("emp_id") + ";" + Eval("days_worked") + ";" + Eval("total_absents") + ";" + Eval("days_marked") %>'
    OnClick="ButtonLink_Click" 
    ForeColor="black" 
    Font-Underline="false" />

then in ButtonLink_Click:

protected void ButtonLink_Click(object sender, System.EventArgs e)
{
    LinkButton lnkRowSelection = (LinkButton)sender;
    string[] arguments = lnkRowSelection.CommandArgument.Split(';');
    string emp_id = arguments[0];
    string days_worked = arguments[1];
    string total_absents = arguments[2];
    string days_marked = arguments[3];

    // pass emp_id, days_worked, total_absents, and days_marked to another page via query string
    Response.Redirect(string.Format("ManualAttendance.aspx?id={0}&daysworked={1}&totalabsents={2}&daysmarked={3}", emp_id, days_worked, total_absents, days_marked), false);
}
