Exporting with Programming Code Using the built-in export feature of the Crystal Reports viewer is nice, but as in most things related to programming, what you get in ease of use you give up in functionality. To get the most functionality for exporting a report, you have to write the programming code yourself. It is […]
18.04 Server Side Modifications
Making Server Side Report Modifications The last section showed how the client is limited to using the viewer control for making runtime modifications. This doesn’t give you many options for making runtime modifications. But that doesn’t mean that it is impossible to make changes using the ReportDocument class. You just have to do it on […]
18.03 Client Side Modifications
Making Client Side Runtime Modifications Report web services can have a minor number of modifications made to them during runtime. As you learned in Chapter 14, the most flexible way to make runtime report modifications is by using the ReportDocument class. It is far more robust than the viewer control which only has a few […]
18.02 Consuming the Report Service
Consuming the Report Service The second part is creating an application to consume the report’s web service. To create an application that consumes the web service, open a new instance of the Visual Studio IDE and create a new Windows application (or an ASP.NET application). Add a CrystalReportViewer control to your form and bind it […]
18.01 Web Services
Creating reports as Report Web Services (RWS) enables you to deliver reports using SOAP via an HTTP protocol. There are no issues with worrying about the report being blocked by security or network constraints. There are two parts to viewing reports as a web service. The first part is to build the web service application […]
17.19 Caching Data
Caching Data If you are building an ASP.NET website, it is important to optimize the web server’s memory. Reports can be quite large, and when you have many users on the site then they can consume a lot of the server’s resources. You can optimize reports by caching them. This saves them to memory so […]
17.18 DLLs and DataSets
Reporting from DataSets in a DLL Crystal Reports also gives you the ability to report from DataSets that are within a separate DLL. In a multi-tier architecture, this lets you build reports directly from the data layer without having to write extra code to encapsulate the dataset in a local object variable. The steps for […]
17.17 DataReaders
Reporting from the DataReader Many people process data using the DataReader class and they want to run reports from it as well. Crystal Reports gives you the ability to do this. The DataReader class is another one of the many data types that can be passed to the SetDataSource() method. Using the DataReader as a […]
