Design side look like this
Default page : Server side
Insert data into the two different table using below code
using System.Data;
using System.Data.SqlClient;
using System.Configuration;
public partial class _Default : System.Web.UI.Page
{
SqlConnection sqlcon = new SqlConnection(ConfigurationManager.ConnectionStrings["Con"].ToString());
SqlCommand sqlcmd = new SqlCommand();
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btnSubmit_Click(object sender, EventArgs e)
{
try
{
sqlcon.Open();
sqlcmd = new SqlCommand("insert into emp(eno,empname,sal,desig) values('" + txteno.Text + "','" + txtempname.Text + "','" + txtsal.Text + "','" + txtdesign.Text + "')", sqlcon);
sqlcmd.ExecuteNonQuery();
sqlcmd = new SqlCommand("insert into empdet(eno,add1,add2,city,state,country) values('" + txteno.Text + "','" + txtAdd1.Text + "','" + txtAdd2.Text + "','" + txtcity.Text + "','" + txtstate.Text + "','" + txtCountry.Text + "')", sqlcon);
sqlcmd.ExecuteNonQuery();
Label1.Text = "Record insert successfully";
clear();
}
catch (Exception ex)
{
}
finally
{
sqlcon.Close();
}
}
void clear()
{
foreach (Control c in form1.Controls) //This loop takes all controls from the form1
{
//Clear all textbox values
if (c is TextBox)
((TextBox)c).Text = "";
//clear all check boxes
if (c is CheckBox)
((CheckBox)c).Checked = false;
//Clear all radio buttons
if (c is RadioButton)
((RadioButton)c).Checked = false;
}
}
}Create Dataset with fields
Now right click on the project name add DataSet1.xsd into the App_Code folder and right click on the designer to add new datatable with the table fields like below
Create Crystal Report
Now right click on the Project name again and add new crystal report in the project name it as CrystalReport.rpt
Then right click on the Field Explorer and choose database expert choose newly created DataSet1 -> DataTable1 and click ok button to add that DataSet1 Fields in the crystal report designer.
Design Crystal report
Design your crystal report with the Field explorer fields and follow below steps to create sub report
1) Right click on your section choose Insert section below 
2) Right click on details section choose -- > Insert sub report 
3) If you design already design sub report then choose a crystal report in a project otherwise choose Create a sub report with report wizard
4) Now double click on the sub report to open sub report 
5) Design sub report using field explorer and after that right click and close sub report
6) Desgin your primary report to using datatable1 
That's all now create one page to display crystal report in web pageDefault2 Page: Client side
