主题：自定义加载树，错误提示！！

Dim Filter As String

If e.Node.Text = "加载所有数据" Then
    Filter = ""
Else
    Dim dr As DataRow = e.Node.DataRow '获取生成此节点的行
    Dim pname As String = dr("派单完成")
    Dim Year As Integer = dr("年")
    Dim Month As Integer = dr("月")
    Select Case e.Node.Level
        Case 0
            If dr.IsNull("派单完成") = False Then
                Filter ="[派单完成] = " & dr("派单完成") & ""
            End If
        Case 1
            Filter ="Year(日期) = " & Year
        Case 2
            Filter ="Year(日期) = " & Year & " And Month(日期) = " & Month
    End Select
End If

With DataTables("生产派单")
    .LoadFilter = Filter
    .LoadPage = 0
    .LoadTop = 10
    .Load()
    e.Form.Controls("TextBox1").Value = 1 & "/" & .TotalPages
End With

 

 如果是sqlserver数据源，可能要这样改。

 

Dim Filter As String

If e.Node.Text = "加载所有数据" Then
    Filter = ""
Else
    Dim dr As DataRow = e.Node.DataRow '获取生成此节点的行
    Dim pname As String = dr("派单完成")
    Dim Year As Integer = dr("年")
    Dim Month As Integer = dr("月")
    Select Case e.Node.Level
        Case 0
            Filter ="[派单完成] = " & iif(dr("派单完成") = False, 0, 1)
        Case 1
            Filter ="Year(日期) = " & Year
        Case 2
            Filter ="Year(日期) = " & Year & " And Month(日期) = " & Month
    End Select
End If

With DataTables("生产派单")
    .LoadFilter = Filter
    .LoadPage = 0
    .LoadTop = 10
    .Load()
    e.Form.Controls("TextBox1").Value = 1 & "/" & .TotalPages
End With

 

 

sqlserver的逻辑列，不能用false和true，要用0和1
