如何在特定的行索引之后过滤高级数据网格视图？

Question

我有一个高级数据网格视图，即NameTable。在高级Datagrid视图中使用过滤器选项时，前两行不应进行过滤或排序。过滤器选项应仅在第二行之后适用。

Public Class Form1
    Public DtTable As DataTable
    Private SBind As BindingSource = New BindingSource()
    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load

        DtTable = New DataTable
        With DtTable
            .Columns.Add(" Name", GetType(String))
            .Columns.Add("Age" + vbLf + " (kg/hr)", GetType(String))
            .Columns.Add("Subject ", GetType(String))
            .Columns.Add(" Marks")
        End With
        Dim dr As DataRow
        For i = 0 To 1
            dr = DtTable.NewRow()
            dr(0) = vbNullString
            dr(1) = vbNullString
            Select Case i
                Case 0
                    dr(2) = "Maths"
                Case 1
                    dr(2) = "Science "
            End Select
            DtTable.Rows.Add(dr)
        Next
        dr = DtTable.NewRow()
        dr(0) = "Mark"
        dr(1) = "18"
        dr(2) = vbNullString
        dr(3) = "98"
        DtTable.Rows.Add(dr)

        dr = DtTable.NewRow()
        dr(0) = "Rachel"
        dr(1) = "18"
        dr(2) = vbNullString
        dr(3) = "60"
        DtTable.Rows.Add(dr)

        SBind.DataSource = DtTable
        DataGridView1.DataSource = SBind

    End Sub
 Private Sub IPFSourceADGV_SortStringChanged(sender As Object, e As EventArgs) Handles IPFSourceADGV.SortStringChanged

        Me.SBind.Sort = Me.IPFSourceADGV.SortString
    End Sub
     Private Sub datagridview1_SortStringChanged(sender As Object, e As EventArgs) Handles datagridview1.SortStringChanged

        Me.SBind.Sort = Me.datagridview1.SortString
    End Sub

    Private Sub datagridview1_FilterStringChanged(sender As Object, e As EventArgs) Handles datagridview1.FilterStringChanged
        Me.SBind.Filter = Me.datagridview1.FilterString
    End Sub

End Class

SampleTable

这只是过滤整个表。

Dim DtTable As DataTable = New DataTable

With DtTable
    .Columns.Add(" Name", GetType(String))
    .Columns.Add("Age" + vbLf + " (kg/hr)", GetType(String))
    .Columns.Add("Subject ", GetType(String))
    .Columns.Add(" Marks")
End With

For Each row As DataRow In DtTable.Rows
    If DtTable.Rows.Count <> 0 Then
        If DtTable.Rows.IndexOf(row) > 2 Then
            ' filter
        End If
    End If
Next

我不知道我是否正确理解...

这样，您可以在表格的第二行之后工作。告诉我。
