No ReportViewer Parameter Prompt

ReportViewer Parameter

I have a ReportViewer on my ASP.NET 3.5 web page.

In my VB code I set a report parameter for the report:

Dim parameters() As ReportParameter = (Session("Resident_ID"))
ReportViewer1.SetParameters(parameters)

The last line of code gives me this error msg. in the design environment: "SetParameters is not a member of Microsoft.Reporting.Webforms.ReportViewer"

Any ideas what I should do?

 

ReportViewer Parameter

I changed the code to:

Dim p1 As New ReportParameter("Resident_ID", ToString()) 'Session("Resident_ID")))
p1 = Session("Resident_ID")
ReportViewer1.LocalReport.SetParameters(p1)

Now I get a different error:

"Unable to cast object of type 'System.String' to type 'Microsoft.Reporting.WebForms.ReportParameter'."

Any idea what I'm doing wrong?

 

Hi,
Browse these forums, I've seen a few threads there for this, at times it appears to be a cast type, array, etc.

ReportViewer Parameter

I am trying a different approach using the following code:

ReportViewer1.ShowParameterPrompts = True
ReportViewer1.ShowPromptAreaButton = True
ReportViewer1.ShowToolBar = True

Yet when I run the page I don't get the prompt and I get the following error in the ReportViewer:

"The 'Resident_ID' parameter is missing a value"

This parameter is specified in the report .rdlc

 

I have a ReportViewer tied to an .rdlc report with a parameter named Resident_ID. In the VB code of the PageLoad event I have the following code:

ReportViewer1.ShowParameterPrompts = True
ReportViewer1.ShowPromptAreaButton = True
ReportViewer1.ShowToolBar = True

Yet when I run the page I don't get the prompt and I get the following error in the ReportViewer:

"The 'Resident_ID' parameter is missing a value"

Any ideas what I am doing wrong?
