Totally fed with crystal web and paramters

[Trainingjason]

I am newbie to vb.net and crystal.net but not crystal. I am passing a date range parameter to crystal by overwriting a preexisiting parameter. I have a dropdown list with date ranges, and a button to show the report.

Works OK until I want to see the data in page 2. No data appears, even though I now there is.

So I now try to Then hell breaks loose. Iniatially I added code to the page_load event
If IsPostback=true then
With CrystalReportViewer1
.reportsource="c:\test\test.rpt"
.visible=true
end with
end if

Obviously I had not passed any values to the parameter. When the form loads, errors occur for currentparametervalues. So I now need to pass a null or a fictious date which returns no data, on start up, or returns the parameterised values for page 2 onwards.

I hate crystal.net

Jason - I hear ya - I have never been a Crystal fan myself, although I suppose if one can master it, it is quite a tool (something like Photoshop, if you know what you're doing you can carry out some serious graphic feats).

I can tell you that there have been some posts here at the ASP.NET forum over the months on Crystal reports, so you might do a quick search - alternatively, if you don't get much response here, you might want to post at the Crystal forum and carry out a more limited search at sites specializing in Crystal reports.
