Hi,
I am using a webform with one text box to pass a string parameter to a CR. The code is below.
When the page loads it asks..
The report you requested requires further information.
--------------------------
and has a textbox for the param. If I ignore this and enter my param the CR opens and displays correctly. I thought setting
CrystalReportViewer1.Enabl
Missing parameter values.
Anyone have any suggestions?
Private Sub GenerateRPT(ByVal ProductID As String)
' Declare variables needed to pass the parameters
' to the viewer control.
Dim paramFields As New ParameterFields()
Dim paramField As New ParameterField()
Dim discreteVal As New ParameterDiscreteValue()
'Dim rangeVal As New ParameterRangeValue()
' The first parameter is a discrete parameter with multiple values.
' Set the name of the parameter field, this must match a
' parameter in the report.
paramField.ParameterFieldN
' Set the first discrete value and pass it to the parameter
discreteVal.Value = ProductID
paramField.CurrentValues.A
paramFields.Add(paramField
' Set the parameter fields collection into the viewer control.
CrystalReportViewer1.Param
CrystalReportViewer1.Repor
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim ProdId As String
ProdId = txtProductID.Text
GenerateRPT(ProdId)
End Sub

When does this appear?
The report you requested requires further information.
I think I know the order of events
You open the page with the viewer
It prompts for information
You enter the information into your text box
You click a button to generate the report.
Is the viewer somehow associated with a report before you open the form? I suspect it is and the report requires parameters. When you enter a value then press the button it overrides the original request and you don't get prompted again.
Setting EnableParameterPrompt to False works to disable parameter prompting when the report opens but only if a parameter has been supplied. If the viewer has a report it may be trying to load the report as the form/viewer loads but no parameter has been passed or entered at that point so the report prompts.

I suspect the name is incorrect or the value is the wrong type.
From VB the names are of the form {?ParamName}. I don't know if the ASP interface requires you to use the { } or the ?. you might try that.
Here are some CR9 ASP examples. I don't think much changed.
