Database
Here I am making use of Microsoft’s Northwind Database. You can download it from here
 
1. Add Typed DataSet to the ASP.Net Website
Since I am using disconnected Crystal Reports we will make use of Typed DataSet to populate the Crystal Reports with data from database.

2. Adding DataTable to the Typed DataSet
Our next step would be to add a DataTable to the Type DataSet.

3. Adding Columns or fields to DataTable
In the DataTable we need to specify the column names that we want to display in the Crystal Report.
 
Note: The Column Names of the DataTable must exactly match with the actual Database Table column names.

By default all the columns are of String Data Type but you can also change the data type as per your need.
 
4. Adding the RDLC Report
Using the Add New Item option in Visual Studio you need to add new RDLC Report. I am making use of Report Wizard so that it make easier to configure the Report.

5. Choose the DataSet
Now we need to choose the DataSet that will act as the DataSource for the RDLC Report. Thus we need to select the Customers DataSet that we have created earlier.

6. Choose the Fields to be displayed in the RDLC Report
Next we need to choose the fields we need to display, we need to simply drag and drop each fields into the Values Box as shown in the screenshot below

7. Choose the Layout
The next dialog will ask us to choose the layout, we can simply skip it as of now as this is a simple Report with no calculations involved.

8. Choose the Style
Finally we need to choose the style, i.e. color and theme of the Report.

Once you press Finish button on the above step, the Report is ready and is displayed in the Visual Studio as shown below

9. Adding Report Viewer to the page
In order to display the Report we will need to add ReportViewer control to the page from the Toolbox. The ReportViewer controls requires ScriptManager on the page.

Once you add the ReportViewer control to the page, your page must look as below
<%@ Register Assembly="Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
    Namespace="Microsoft.Reporting.WebForms" TagPrefix="rsweb" %>
 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager>
    <rsweb:ReportViewer ID="ReportViewer1" runat="server" Width="600">
    </rsweb:ReportViewer>
    </form>
</body>
</html>
 
 
10. Populating the RDLC Report from Database
Below is the code to populate the RDLC Report from database. The first statement notifies the ReportViewer control that the Report is of type Local Report.
Then the path of the Report is supplied to the ReportViewer, after that the Customers DataSet is populated with records from the Customers Table is set as ReportSource to the Report.

    {
        ReportViewer1.ProcessingMode = ProcessingMode.Local;
        ReportViewer1.LocalReport.ReportPath = Server.MapPath("~/Report.rdlc");
        Customers dsCustomers = GetData("select top 20 * from customers");
        ReportDataSource datasource = new ReportDataSource("Customers", dsCustomers.Tables[0]);
        ReportViewer1.LocalReport.DataSources.Clear();
        ReportViewer1.LocalReport.DataSources.Add(datasource);
    }
}
 
private Customers GetData(string query)
{
    string conString = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
    SqlCommand cmd = new SqlCommand(query);
    using (SqlConnection con = new SqlConnection(conString))
    {
        using (SqlDataAdapter sda = new SqlDataAdapter())
        {
            cmd.Connection = con;
 
            sda.SelectCommand = cmd;
            using (Customers dsCustomers = new Customers())
            {
                sda.Fill(dsCustomers, "DataTable1");
                return dsCustomers;
            }
        }
    }
}
