ReportViewer 및 Global.System.Diagnostics.DebuggerNonUserCodeAttribute가 포함 된 무한 루프

Question

텍스트 상자 1 개와 Reoprt Wizard에서 만든 ReportViewer가 포함 된 간단한 webForm을 작성했습니다. 보고서를 실행하려고 할 때 오류가 발생하지 않지만 보고서가로드되지 않습니다. 나는 .rdlc 파일을 두 번 체크했다. (.xsd 파일 미리보기를 통해 예상되는 데이터를 표시한다.) 그래서 문제를 식별 할 수 있는지를 알기 위해 내 코드에 중단 점을 설정했다. 어떻게 든 코드가 성공적으로 완료되고 ReportViewer 코드를 새로 고친 다음 4 개의 함수를 실행하기 위해 Designer.vb 파일로 이동 한 다음 다시 ReportViewer 코드로 돌아갑니다. Designer.vb 코드에서 어떤 일이 발생하는지 이해하지 못합니다. 내가 잘못 했어 내가 ASP.net, 뒤에 VB 코드 및 Designer.vb 파일에서 코드의 4 개 블록을 포함 할 수 있습니다

ASP.net 코드 :?.

VB 코드 뒤에 :

Imports Microsoft.Reporting.WebForms 

Public Class VacationSick_EmployeeReportByArea 
Inherits System.Web.UI.Page 

'Declare Variables 
Dim Choose_Year As String 

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 
    'Default the Year in ddl to this year 
    If (Page.IsPostBack) = False Then 
     ddl_Year.SelectedValue = Now.Year 
    End If 

    'When the page loads, fill the report with the current year's data 
    Choose_Year = ddl_Year.SelectedValue.ToString() 
    rv_EmployeeReportByArea.LocalReport.ReportPath = "VacationSick\VacationSick_ReportByArea.rdlc" 
    Dim Param As New ReportParameter("Year", "2014") 
    rv_EmployeeReportByArea.LocalReport.SetParameters({Param}) 
    rv_EmployeeReportByArea.ServerReport.Refresh() 
End Sub 

파일 Dilbert_VacationSickByArea.Designer.vb에서이 4 개 코드 블록이 실행 된 후 그것은의 ReportViewer에 대한 PageLoad 코드로 돌아갑니다 :

Answer 1

보고서에만 If Not Me.Page.IsPostBack을 인쇄 해보십시오.

LocalReport을 사용 중이기 때문에 rv_EmployeeReportByArea.ServerReport.Refresh()을 삭제할 수도 있습니다.
