vb.net microsoft reporting servicesprojects 2022 动态代码连接sql数据库，显示预览报表，另外有多项数据时可分页

以下是VB.NET Microsoft Reporting Services Projects 2022动态代码连接SQL数据库，显示预览报表，以及分页的示例：

首先，您需要创建一个报表，并在其上设置数据源。然后，使用以下代码将报表加载到ReportViewer控件中：

Dim reportPath As String = "YourReportPath.rdlc"
Dim reportDataSource As New ReportDataSource("YourDataSetName", YourDataTable)
ReportViewer1.LocalReport.ReportPath = reportPath
ReportViewer1.LocalReport.DataSources.Clear()
ReportViewer1.LocalReport.DataSources.Add(reportDataSource)
ReportViewer1.RefreshReport()

其中，`YourReportPath.rdlc`是您的报表路径，`YourDataSetName`是您的数据集名称，`YourDataTable`是您的数据表。

接下来，您可以使用以下代码设置ReportViewer控件的分页：

Dim pageSettings As New System.Drawing.Printing.PageSettings()
pageSettings.Landscape = False '横向打印
pageSettings.PaperSize = New System.Drawing.Printing.PaperSize("A4", 827, 1169) '纸张大小
pageSettings.Margins.Left = 10 '左边距
pageSettings.Margins.Right = 10 '右边距
pageSettings.Margins.Top = 10 '上边距
pageSettings.Margins.Bottom = 10 '下边距
Dim pageCount As Integer
Dim warnings As Warning()
Dim streamids As String()
Dim mimeType As String = ""
Dim encoding As String = ""
Dim extension As String = ""
Dim bytes As Byte() = ReportViewer1.LocalReport.Render("PDF", Nothing, mimeType, encoding, extension, streamids, warnings)
pageCount = streamids.Length

其中，`pageSettings`是打印页面设置，您可以根据需要更改其值。最后，`pageCount`将包含报表的总页数。

希望这可以帮助到您！
