HTML Markup:

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
        <rsweb:ReportViewer ID="ReportViewer1" runat="server" Font-Names="Verdana" Font-Size="8pt" WaitMessageFont-Names="Verdana" WaitMessageFont-Size="14pt" Width="793px">
            <LocalReport ReportPath="Mainreport.rdlc">
                <DataSources>
                    <rsweb:ReportDataSource DataSourceId="ObjectDataSource1" Name="DataSet1" />
                </DataSources>
            </LocalReport>
        </rsweb:ReportViewer>
        <asp:ObjectDataSource ID="ObjectDataSource1" runat="server" SelectMethod="GetData" TypeName="DataSetTableAdapters.GetStatePopulationTableAdapter"></asp:ObjectDataSource>
    </div>
    </form>
</body>
</html>

Now write the code in code file.

Add the namespace

C#.net code
using System.Data;
using System.Data.SqlClient;
using System.Configuration;
using Microsoft.Reporting.WebForms;

VB.net code:
Imports System.Data
Imports System.Data.SqlClient
Imports System.Configuration
Imports Microsoft.Reporting.WebForms


C#.net code

   SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["TestDatabaseConnectionString"].ToString()); 

    protected void Page_Load(object sender, EventArgs e)
    {
        if(!IsPostBack)
        {
            Bindreport();
        }
    }

    public void Bindreport()
    {
        DataTable dt = new System.Data.DataTable();
        SqlDataAdapter adp = new SqlDataAdapter("GetStatePopulation", con);
        adp.SelectCommand.CommandType = CommandType.StoredProcedure;
        adp.Fill(dt);
        ReportViewer1.LocalReport.DataSources.Clear();
        ReportDataSource reportdatasource = new ReportDataSource("DataSet1", dt);
        ReportViewer1.LocalReport.DataSources.Add(reportdatasource);
        ReportViewer1.LocalReport.SubreportProcessing += new SubreportProcessingEventHandler(SubreportProcessing);
    }

    void SubreportProcessing(object sender, SubreportProcessingEventArgs e)
    {
        int stateid = int.Parse(e.Parameters["stateid"].Values[0].ToString());
        DataTable dt = new System.Data.DataTable();
        SqlDataAdapter adp = new SqlDataAdapter("GetDistrictPopulation", con);
        adp.SelectCommand.CommandType = CommandType.StoredProcedure;
        adp.SelectCommand.Parameters.AddWithValue("@stateid",stateid);
        adp.Fill(dt);
        ReportDataSource dts = new ReportDataSource("DataSet1", dt);
        e.DataSources.Add(dts);
    }

VB.net code:

Private con As New SqlConnection(ConfigurationManager.ConnectionStrings("TestDatabaseConnectionString").ToString())

    Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
        If Not IsPostBack Then
            Bindreport()
        End If
    End Sub

    Public Sub Bindreport()
        Dim dt As DataTable = New System.Data.DataTable()
        Dim adp As New SqlDataAdapter("GetStatePopulation", con)
        adp.SelectCommand.CommandType = CommandType.StoredProcedure
        adp.Fill(dt)
        ReportViewer1.LocalReport.DataSources.Clear()
        Dim reportdatasource As New ReportDataSource("DataSet1", dt)
        ReportViewer1.LocalReport.DataSources.Add(reportdatasource)
        AddHandler ReportViewer1.LocalReport.SubreportProcessing, AddressOf SubreportProcessing
    End Sub
   
Private Sub SubreportProcessing(sender As Object, e As SubreportProcessingEventArgs)
        Dim stateid As Integer = Integer.Parse(e.Parameters("stateid").Values(0).ToString())
        Dim dt As DataTable = New System.Data.DataTable()
        Dim adp As New SqlDataAdapter("GetDistrictPopulation", con)
        adp.SelectCommand.CommandType = CommandType.StoredProcedure
        adp.SelectCommand.Parameters.AddWithValue("@stateid", stateid)
        adp.Fill(dt)
        Dim dts As New ReportDataSource("DataSet1", dt)
        e.DataSources.Add(dts)
    End Sub

Build the website and run.
