Private Sub ToolStripButton1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ToolStripButton1.Click
    Dim cryRpt As New ReportDocument

    cryRpt.Load("D:\Orly\workspace\HMIS\01.26.15\HoMISv2.0\CRMedicalRecords.rpt")

    Dim crParameterFieldDefinitions As ParameterFieldDefinitions
    Dim crParameterFieldDefinition As ParameterFieldDefinition
    Dim crParameterValues As New ParameterValues
    Dim crParameterDiscreteValue As New ParameterDiscreteValue

    crParameterDiscreteValue.Value = Nurse.SelectedPatient
    crParameterFieldDefinitions = cryRpt.DataDefinition.ParameterFields
    crParameterFieldDefinition = crParameterFieldDefinitions.Item("PCode")
    crParameterValues = crParameterFieldDefinition.CurrentValues

    crParameterValues.Clear()
    crParameterValues.Add(crParameterDiscreteValue)
    crParameterFieldDefinition.ApplyCurrentValues(crParameterValues)

    CRMedicalRecords.ReportSource = cryRpt
End Sub

我希望你能帮我解决这个问题。

请在 Crystal Reports 或 Visual Studio 中打开报表并检查 文件 > 报告选项 要关闭“只读”选项。

这可能会阻止您编辑报告，就像添加参数一样。
