steps:
• Add a new web project
• Add a new item to the project “crystal report”
• Choose “Using the report wizard” to create a new report or simply choose “From an existing report” if you already have an existing crystal report. You could choose a “blank report” to create a report form scratch”.
• Choose the data source
• Browse data and fields that you want to show in the report.
• And choose finish
• Now you can design the report and customize it
If you want you add crystal report in web/windows forms as well using crystal report viewer control.

The .RPT files are created using the Crystal Reports Designer, which is available as a stand-alone program, or an add-in to Visual Studio. Many versions of Visual Studio ship with a version of the Crystal Reports designer add-in, meaning you can create Crystal Reports within Visual Studio without having to buy additional software or licenses.
After you have created the Crystal Report file, the next step is defining a data schema. After you have “informed” the Crystal Report file of the data schema, a list of fields obtained from the data schema, will appear in the field explorer. Once the fields appear in the field explorer, you can "drag" the field to the report.
Below is what the EmployeeData.xml contains. You will notice each field is listed with the data type.
Listing:-
To "inform" the Crystal Reports file of the data schema, click on the Database Expert option in the toolbar, click Create New Connection and select ADO.NET (XML) , and select the data schema that was just generated.
Once your data schema has been defined, you should see a list of columns in the Field Explorer under Database Fields.
Now that the Crystal Reports file has been created, you need to display the report in your project. For our example, we will be using the Crystal Reports ASP.NET controls. The methods outlined here are very similar to the Win Forms controls as well.
To view your newly created Crystal Report file in your custom application, you will need to use the Crystal Report Viewer control as shown in the code below.
Untitled Page
Now that the control is on the page, we need to “inform” the Crystal Reports Viewer control of the Crystal Reports file. We can do this in the code behind with the code that follows.
ReportDocument employeesReport = new ReportDocument();
crvMain.ReportSource = employeesReport; After this step has been completed, we need set the data for the Crystal Report file that was loaded in the viewer. We simply use the SetDataSource method on the ReportDocument object.
ReportDocument employeesReport = new ReportDocument();
employeesReport.Load(@"\Employees.rpt");
employeesReport.SetDataSource(employees);
crvMain.ReportSource = employeesReport; When all is said and done, you should have some type of method that looks similar to the LoadReport method below.
private void LoadReport()
{
List employees = GetEmployeesAsList();
DataSet employeeDataSet = ListToDataset(employees);
ReportDocument employeesReport = new ReportDocument();
try
{
employeesReport.Load(@"Reports\Employees.rpt");
employeesReport.SetDataSource(employees);
crvMain.ReportSource = employeesReport;
}
catch (Exception ex)
{
lblError.Text = string.Format
("A system error has occurred while loading the report {0}", ex.Message);
}
finally
{
employeesReport = null;
}
}
If you have followed all the steps above, you should now have your Crystal Report rendering in your custom application.
