Introduction :
  Hi, Here i will explain how to create the RDLC reports using ReportViewer by getting data from Database.   I have created a TextBox and a Button control by entering a ID in the Textbox, on Button Click, the details  of the students are Shown in the ReportViewer with RDLC Reports.

Step 1 : Create the Database,Table for Which you are going to insert

Step 2 : Create New project 

Step 3 : Create New Page and Add ScriptManager and ReportViewer to the created page, as images Shown below.

After Adding ScriptManager and ReportViewer your page looks as Below.

Step 4 : Create a Dataset file as below in your project.

Step 5: Create the DataAdapter by Right Click in the Dataset File as below.

 Complete the DB Connection wizard as below  :

Your Dataset File looks as below. You can create one or More number of Adapters for a Dataset File

Step 6 :  Create a RDLC File in your Solution as Below.

Then go to Menu of visual studio View > ReportData.

Here you need to create a new Dataset as below

Three Steps to follow from here.
1.       Give the name of the Dataset you have created.
2.       Select the Datasource name as the file name of DataSet file which you previously created.
3.       Select the appropriate Dataset listed in Available Datasets.

Step 7 : Now lets start design the RDLC File as shown below.

Here I will show report by entering ID of the user which is in the Database.
As your Aspx page Should looks Like below.

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Page1.aspx.cs" Inherits="RDLCReport.Page1" %>

<%@ Register Assembly="Microsoft.ReportViewer.WebForms, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
    Namespace="Microsoft.Reporting.WebForms" TagPrefix="rsweb" %>

<!DOCTYPE html >
<head runat="server">
    <form id="form1" runat="server">
    <asp:TextBox ID="txtID" runat="server"></asp:TextBox>
    <asp:Button ID="btn1" runat="server" Text="Generate report"
        onclick="btn1_Click" />
        <br />
        <br />
        <asp:ScriptManager ID="ScriptManager1" runat="server">
        <rsweb:ReportViewer ID="ReportViewer1" runat="server" Visible="false">
        <LocalReport ReportPath="Report1.rdlc"></LocalReport>

Note: <LocalReport ReportPath="Report1.rdlc"></LocalReport> should be given inside your report viewer, Give your RDLC page name as ReportPath where I have given as Report1.rdlc

Your Code Behind ( C# ) :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Microsoft.Reporting;
using Microsoft.ReportingServices;
using Microsoft.Reporting.WebForms;
using System.Configuration;
using System.ComponentModel;
using System.Drawing;
using System.Text;
using System.Data;
using System.Data.SqlClient;

namespace RDLCReport
    public partial class Page1 : System.Web.UI.Page
        protected void Page_Load(object sender, EventArgs e)


        protected void btn1_Click(object sender, EventArgs e)
            ReportViewer1.Visible = true;
            int id =Convert.ToInt32(txtID.Text);
            ReportViewer1.ProcessingMode = ProcessingMode.Local;
            ReportViewer1.LocalReport.ReportPath = Server.MapPath("~/Report1.rdlc");
            DataSet ds = new DataSet();
            ds = GetData(id);
            if (ds.Tables[0].Rows.Count > 0)
                ReportDataSource rds = new ReportDataSource("DatasetName", ds.Tables[0]);

        private DataSet GetData(int id)
            SqlConnection con = new SqlConnection("Your Connection String");
            SqlCommand cmd = new SqlCommand("select * from Table1 where ID="+id+"");
            using (con)
                using (SqlDataAdapter da = new SqlDataAdapter())
                    cmd.Connection = con;
                    da.SelectCommand = cmd;
                    DataSet ds = new DataSet();
                    return (ds);

Add if the below lines of code is not available in your web-config File :

      <add path="Reserved.ReportViewerWebControl.axd" verb="*" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
