How can I select all items in a reportparameter when loading the report in the reportviewer?
I know I can set the value as follows:
Dim rep As New webreports.reportname
rep.ReportParameters("Period").Value = "aaa"
But I want to select all items when the reports loads for the first time, after that the user can drop any selected items.
rep.ReportParameters("Period").Value = "aaa; bbb"
but that doesn't work.
