ASP.NET 中 ListView 的自定义 DataPager

我想获得 C# 和 VB.NET 建议。

我有以下 DataPager 来处理 ListView 的分页。

DataPager 标记

 <asp:DataPager ID="dpComputer" runat="server" 
        PagedControlID="lvComputer" PageSize="10">
        <Fields>
            <asp:NextPreviousPagerField ShowFirstPageButton="True" ShowNextPageButton="False"  />
            <asp:NumericPagerField NumericButtonCssClass="dpTimeSheet" ButtonCount="100" ButtonType="Image" />
            <asp:NextPreviousPagerField ShowLastPageButton="True" ShowPreviousPageButton="False"  />
        </Fields>
    </asp:DataPager>

处理 DataPager 事件

        Protected Sub lvComputer_PagePropertiesChanged(ByVal sender As Object, ByVal e As EventArgs) Handles lvComputer.PagePropertiesChanged
    
            LoadData()
      
        End Sub

显示/隐藏 datapager

    Protected Sub lvComputer_DataBound(ByVal sender As Object, ByVal e As EventArgs) Handles lvComputer.DataBound

        dpComputer.Visible = dpComputer.PageSize <= dpComputer.TotalRowCount

    End Sub

上面的代码产生以下输出：

第一页上一页 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 依此类推下一页最后一页

我上面的代码工作正常。然而，当ListView lvComputer的TotalRows超过200时，页面上的分页数很多。我想按以下格式显示寻呼号码：

第一页上一页 1 2 3 ..... 9 10 11 下一页最后一页
首页上一页 5 6 7 8 ..... 13 14 15 16 下一页末页

我需要以编程方式修改数据分页器以获得如上所述的所需结果例子？谢谢。

I'd like to get both C# and VB.NET suggestion.

I have the follow DataPager to handle the paging of ListView.

DataPager mark-up

 <asp:DataPager ID="dpComputer" runat="server" 
        PagedControlID="lvComputer" PageSize="10">
        <Fields>
            <asp:NextPreviousPagerField ShowFirstPageButton="True" ShowNextPageButton="False"  />
            <asp:NumericPagerField NumericButtonCssClass="dpTimeSheet" ButtonCount="100" ButtonType="Image" />
            <asp:NextPreviousPagerField ShowLastPageButton="True" ShowPreviousPageButton="False"  />
        </Fields>
    </asp:DataPager>

handling DataPager event

        Protected Sub lvComputer_PagePropertiesChanged(ByVal sender As Object, ByVal e As EventArgs) Handles lvComputer.PagePropertiesChanged
    
            LoadData()
      
        End Sub

show/hide datapager

    Protected Sub lvComputer_DataBound(ByVal sender As Object, ByVal e As EventArgs) Handles lvComputer.DataBound

        dpComputer.Visible = dpComputer.PageSize <= dpComputer.TotalRowCount

    End Sub

The code above makes the following output:

First Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 and so on Next Last

The code I have above works fine. However,when TotalRows of ListView lvComputer is more than 200, there are a lot of paging number on the page.
I want to show paging number like something in the following format:
