In the crystal report to create the report, we start out
with the report wizard. For a data connection, choose Create New Connection,
ADO.NET. Once you select that you will be prompted for the location of your
class library wrapper. Using the File Path ellipses prompt, find and put the
location of your DLL into the connection information or you can just cut and
paste it in (see Figure 1).
Figure 1
Also specify the Class name (this should show up in the drop
down) and then specify using the dataset from class. This should be the
wrapper method you set up that returns a dataset. The code would be something
like in Listing 2.
Listing 2
using System;
using System.Collections.Generic;
using System.Data;
using System.Text;
namespace WrapperCrystalXIWebService
{
public class Class1
{
public DataSet ReturnWS_Info(String strUrl)
{
DataSet dsToReturn = new DataSet("WebService");
WS_MySharepointWS wsSP_WebService = new WS_MySharepointWS();
// Populate the Dataset from Webservice Results here
return dsToReturn;
}
}
}This code in ReturnWS_Info should populate your dataset with
the data returned from the web service. Then simply return the dataset and
Crystal XI will interpret the results into a familiar Grouping like you would
see from a SQL query.
From here using the field explorer, you can place your
fields on different bands in the designer create groupings and other features
you have come to expect from Crystal. You will want to designate a default
parameter to your datasource or you will get prompted many different times when
trying to view the data or the fields.
