由于DataList不支持内建的分页机制，因此，我们必须使用 SqlDataAdapter对象的Fill方法来实现分页，Fill方法主要用来增加或刷新DataSet的记录行。Fill方法已经被重载，我们这里选用四个参数的那个重载方法：DataSet, startRecord, maxRecords 和 TableName。

CInt(intPageSize.Text)) If CInt(intCurrIndex.Text) < 0 Then intCurrIndex.Text = "0" End If DataBind() End Sub Public Sub ShowNext(ByVal s As Object, ByVal e As EventArgs) If CInt(intCurrIndex.Text) + 1 < CInt(intRecordCount.Text) Then intCurrIndex.Text = CStr(CInt(intCurrIndex.Text) + CInt(intPageSize.Text)) End If DataBind() //*************重绑数据 End Sub Public Sub ShowLast(ByVal s As Object, ByVal e As EventArgs) Dim tmpInt as Integer tmpInt = CInt(intRecordCount.Text) Mod CInt(intPageSize.Text) If tmpInt > 0 Then intCurrIndex.Text = Cstr(CInt(intRecordCount.Text) -
