Question

为什么它不会使用此代码向表单2上的reportviewer显示参数。

Imports Microsoft.Reporting.WinForms
Public Class Report
Private Sub Report_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

    Dim parmlist As New List(Of ReportParameter)()
    parmlist.Add(New ReportParameter("CompanyName ", Form1.TextBox1.Text & "Report"))
    parmlist.Add(New ReportParameter("ClientName", Form1.TextBox2.Text))
    parmlist.Add(New ReportParameter("ClientAdress", Form1.TextBox3.Text))

    ReportViewer1.LocalReport.SetParameters(parmlist)

    Me.ReportViewer1.RefreshReport()
    End Sub
End Class

代码没有显示问题。我还添加了具有相同值的参数，并设计为图片。 Image

通过使用此代码，它可以完美运行。

 Dim ime As New ReportParameter("CompanyName", Form1.TextBox1.Text) 
    Dim imec As New ReportParameter("ClientName", Form1.TextBox2.Text) 
    Dim adresa As New ReportParameter("ClientAdress", Form1.TextBox3.Text)  
    ReportViewer1.LocalReport.SetParameters(ime)     
    ReportViewer1.LocalReport.SetParameters(imec) 
    ReportViewer1.LocalReport.SetParameters(adresa) 
    Me.ReportViewer1.RefreshReport()

Microsoft报告的参数
