}
protected void Page_Init(object sender, EventArgs e)

if (Session["report"] != null)
{
CrystalReportViewer1.ReportSource = (RptEmployee)Session["report"];
}
}
protected void Button1_Click(object sender, EventArgs e)
{
MPEmployeeTableAdapters.EMP_DATATableAdapter da = new
MPEmployeeTableAdapters.EMP_DATATableAdapter();
MPEmployee ds = new MPEmployee();
MPEmployee.EMP_DATADataTable dt =
(MPEmployee.EMP_DATADataTable)ds.Tables["EMP_Data"];

da.Fill(dt);

rpt = new RptEmployee();
rpt.SetDataSource(ds);
CrystalReportViewer1.ReportSource = rpt;
Session.Add("report", rpt);

}

}
}

What I have tried:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="EmpReport.aspx.cs" Inherits="MPOffice.EmpReport" %>

<%@ Register assembly="CrystalDecisions.Web, Version=13.0.3500.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" namespace="CrystalDecisions.Web" tagprefix="CR" %>

The quickest way is figure out why it's not displaying is to use the debugger to step into your code. You would need to see the DataSource for your Report if it contains data or not.

Quote:
<Report FileName="C:\Users\ACER_VERITON\source\repos\MPOffice\MPOffice\RptEmployee.rpt">

Another thing to notice is that you were referencing a file that is outside your Project root which can potentially cause an access issue. Try to move your Report file .rpt within your project root and reference it from there.

Here are a couple of tutorials I found on google on how to work with Crytal Reports in ASP.NET:
