Crystal Report Viewer doing Postback on page change

Hi,

We are trying to buld some crystal reports for our reporting purposes. We are using VS 2010, and the add-on Crystal Reports available for VS 2010.

The report design is complete and data is retrieved. We have used the Crystal Report Viewer which comes with the plug in.

The first page displays accurately, but since the amount of data returned is large, the report flows into multiple pages.

When we try to navigate to the next page, the page Posts back, and this forces us to retrieve the data again. We tried binding the dataset to a ViewState just to make it faster, but the postback is still disturbing.

Is there any way to avoid the viewer from Posting Back.

Use IsPostBack and handle the postbacks appropriately.

Kethu, I do not want crystal viewer to postback for every page change of the report. Cannot it load the entire report at one go.

I am not sure how you are loading your crystal report viewer but i have done something like this and not got the problem mentioned by you....

string lstrFileName = Server.MapPath("rptSalesOrder.rpt");
ReportDocument reportDocument = new ReportDocument();
reportDocument.Load(lstrFileName);
DataSourceConnections dataSourceConnections = reportDocument.DataSourceConnections;
IConnectionInfo connectInfo = dataSourceConnections[0];
connectInfo.SetConnection("BITS_01_07", "MOBILE_TEST", "sa", "");
CrystalReportViewer1.ReportSource = reportDocument;
CrystalReportViewer1.RefreshReport();
