SSRS - Pertahankan tabel dengan lebar yang sama saat menyembunyikan kolom secara dinamis?

Satu-satunya cara saya tahu bagaimana mencapai ini, adalah dengan mengubah file RDLC Anda selama runtime. Pada dasarnya, Anda dapat memuat file RLDC Anda ke dalam memori (hanya file XML), cari node XML yang berisi lebar tabel Anda - lalu ubah pengaturan di memori. Setelah Anda selesai melakukannya, Anda dapat menyegarkan kontrol reportViewer Anda menggunakan file RDLC yang dimuat di memori.

Dan ya, saya sudah melakukannya, dan berhasil.

Contoh kode berikut adalah mengubah data file RDLC di memori, melalui XMLpath-nya.

  Private Sub ModifyRDLCInMemory()

    Dim xmlDoc As XmlDocument = New XmlDocument
    Dim asm As Reflection.Assembly = Reflection.Assembly.GetExecutingAssembly()
    'create in memory, a XML file from a embedded resource
    Dim xmlStream As Stream = asm.GetManifestResourceStream(ReportViewer1.LocalReport.ReportEmbeddedResource)

    Try
      'Load the RDLC file into a XML doc
      xmlDoc.Load(xmlStream)
    Catch e As Exception
      MessageBox.Show(e.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error, MessageBoxDefaultButton.Button1)
    End Try

    'Create an XmlNamespaceManager to resolve the default namespace
    Dim nsmgr As XmlNamespaceManager = New XmlNamespaceManager(xmlDoc.NameTable)
    nsmgr.AddNamespace("nm", "http://schemas.microsoft.com/sqlserver/reporting/2005/01/reportdefinition")
    nsmgr.AddNamespace("rd", "http://schemas.microsoft.com/SQLServer/reporting/reportdesigner")

    'Loop through each node in the XML file
    Dim node As XmlNode
    For Each node In xmlDoc.DocumentElement.SelectNodes(String.Format("//nm:{0}[@rd:LocID]", "Value"), nsmgr)  'XPath to LocID node.. You will want to change this to locate your Table Width node. You may need to read up on XMLPath
      Dim nodeValue As String = node.InnerText  'Gets current value of Node
      If (String.IsNullOrEmpty(nodeValue) Or Not nodeValue.StartsWith("=")) Then
        Try
          node.InnerText = YOURNEWVALUE

        Catch ex As Exception
          'handle error
        End Try
      End If
    Next

    ReportViewer1.LocalReport.ReportPath = String.Empty
    ReportViewer1.LocalReport.ReportEmbeddedResource = Nothing
    'Load the updated RDLC document into LocalReport object.
    Dim rdlcOutputStream As StringReader = New StringReader(xmlDoc.DocumentElement.OuterXml)
    Using rdlcOutputStream
      ReportViewer1.LocalReport.LoadReportDefinition(rdlcOutputStream)
    End Using

  End Sub
