'设置数据加载条件
Dim nms() As String = {"DateTimePicker1","DateTimePicker2","ComboBox1","ComboBox3","TextBox1","ComboBox2","TextBox2"}
Dim sps() As String = {"'","'","'","'","'","'","'","'"}
Dim bjf() As String = {" >= "," <= "," = "," = "," like "," = "," = "}
Dim fds() As String = {"认证日期","认证日期","客户区域_省或直辖市","客服分配_分配状态","客户信息_行业类别","客服分配_客服小组","客服分配_客服人员"}
Dim Filter As String
For i As Integer = 0 To nms.length - 1
    If e.Form.Controls(nms(i)).Value IsNot Nothing Then
        If Filter > "" Then
            Filter = Filter & " and "
        End If
        Filter = Filter & fds(i) & bjf(i) & sps(i) & e.Form.Controls(nms(i)).value & sps(i)
    End If
Next
