从搜索引擎优化友好的网址访问数据

Question

我需要一些关于如何从访问数据库中分页数据的帮助。 我使用asp:ListView和asp:DataPager像我发现的一些例子，但与JavaScript的分页工作，我希望分页将是友好的。

我怎么能把我的一些代码？

[编辑] 这是代码：

<asp:ListView ID="tblProjects" runat="server" OnPagePropertiesChanging="tblProjects_PagePropertiesChanging"> 
<LayoutTemplate> 
    <ul class="ulProducts"> 
     <asp:PlaceHolder ID="itemPlaceholder" runat="server" /> 
    </ul> 
</LayoutTemplate> 
<ItemTemplate> 
    <li> 
     <div class="divProduct"> 
      <a rel='pics' href='GalleryEditor/pictures/<%# Eval("BigImageName") %>'> 
       <img src='GalleryEditor/pictures/<%# Eval("SmallImagesName") %>' 
        alt='<%# Eval("ImageDetail") %>' title='<%# Eval("ImageDetail") %>' /> 
      </a> 
     </div> 
    </li> 
</ItemTemplate> 
<EmptyDataTemplate> 
    no data 
</EmptyDataTemplate> 

这后面的代码：

protected void tblProjects_PagePropertiesChanging(object sender, PagePropertiesChangingEventArgs e) 
    { 
     //set current page startindex, max rows and rebind to false 

     imagesPager.SetPageProperties(e.StartRowIndex, e.MaximumRows, false); 

     string page = Request.QueryString["p"]; 
     if (!(FormValidator.IsNumber(page))) 
      page = "8800"; 

     buildProducts(page); 

    } 

    void buildTitleAndDescription(string page) 
    { 
     // set page title 
     OleDbConnection conn0 = new OleDbConnection(@"Provider = Microsoft.Jet.OLEDB.4.0; Data Source =" + Server.MapPath("GalleryEditor\\App_Data\\projects.mdb")); 
     OleDbCommand comm0 = new OleDbCommand("select ProjectName from Project where PlaceID=" + page, conn0); 
     OleDbDataReader reader0; 

     conn0.Open(); 
     reader0 = comm0.ExecuteReader(); 
     reader0.Read(); 

     Page.Header.Title = reader0["ProjectName"].ToString(); 

     reader0.Close(); 
     conn0.Close(); 

     //if (IsPostBack) 
     //{ 
     // string Script = "<script type='text/javascript'>goToEnd();\n</script>"; 
     // Page.ClientScript.RegisterStartupScript(this.GetType(), "onload", Script); 
     //} 

    } 

    void buildProducts(string page) 
    { 

     // set page content 
     OleDbConnection conn = new OleDbConnection(@"Provider = Microsoft.Jet.OLEDB.4.0; Data Source =" + Server.MapPath("GalleryEditor\\App_Data\\sb.mdb")); 
     OleDbCommand comm = new OleDbCommand("select SmallImagesName, BigImageName, ImageDetail from Images where PlaceID=" + page, conn); 

     conn.Open(); 

     DataSet ds = new DataSet(); 
     OleDbDataAdapter da = new OleDbDataAdapter(comm); 
     da.Fill(ds); 

     tblProjects.DataSource = ds; 
     tblProjects.DataBind(); 

    } 

我不介意将代码更改为更好的代码，如果我学习了它，我将不胜感激。 我发现的所有例子都是针对SQL的，我的数据需要被访问。

这里是一个asp列表视图的例子，你将不得不按如下定义查询字符串。

<asp:ListView ID="ListView1" runat="server" DataKeyNames="bd_book_code" 
    DataSourceID="SqlDataSource1" EnableModelValidation="True"> 
    <AlternatingItemTemplate> 
     <tr style=""> 
      <td> 
       <asp:Label ID="bd_book_codeLabel" runat="server" 
        Text='<%# Eval("bd_book_code") %>' /> 
      </td> 
      <td> 
       <asp:Label ID="bd_isbnLabel" runat="server" Text='<%# Eval("bd_isbn") %>' /> 
      </td> 
      <td> 
       <asp:Label ID="bd_titleLabel" runat="server" Text='<%# Eval("bd_title") %>' /> 
      </td> 
     </tr> 
    </AlternatingItemTemplate> 
    <EditItemTemplate> 
     <tr style=""> 
      <td> 
       <asp:Button ID="UpdateButton" runat="server" CommandName="Update" 
        Text="Update" /> 
       <asp:Button ID="CancelButton" runat="server" CommandName="Cancel" 
        Text="Cancel" /> 
      </td> 
      <td> 
       <asp:Label ID="bd_book_codeLabel1" runat="server" 
        Text='<%# Eval("bd_book_code") %>' /> 
      </td> 
      <td> 
       <asp:TextBox ID="bd_isbnTextBox" runat="server" Text='<%# Bind("bd_isbn") %>' /> 
      </td> 
      <td> 
       <asp:TextBox ID="bd_titleTextBox" runat="server"

    <EmptyDataTemplate> 
     <table runat="server" style=""> 
      <tr> 
       <td> 
        No data was returned.</td> 
      </tr> 
     </table> 
    </EmptyDataTemplate> 
    <InsertItemTemplate> 
     <tr style=""> 
      <td> 
       <asp:Button ID="InsertButton" runat="server" CommandName="Insert" 
        Text="Insert" /> 
       <asp:Button ID="CancelButton" runat="server" CommandName="Cancel" 
        Text="Clear" /> 
      </td> 
      <td> 
       <asp:TextBox ID="bd_book_codeTextBox" runat="server" 
        Text='<%# Bind("bd_book_code") %>' /> 
      </td> 
      <td> 
       <asp:TextBox ID="bd_isbnTextBox" runat="server" Text='<%# Bind("bd_isbn") %>' /> 
      </td> 
      <td> 
       <asp:TextBox ID="bd_titleTextBox" runat="server" 
        Text='<%# Bind("bd_title") %>' /> 
      </td> 
     </tr> 
    </InsertItemTemplate> 
    <ItemTemplate> 
     <tr style=""> 
      <td> 
       <asp:Label ID="bd_book_codeLabel" runat="server" 
        Text='<%# Eval("bd_book_code") %>' /> 
      </td> 
      <td> 
       <asp:Label ID="bd_isbnLabel" runat="server" Text='<%# Eval("bd_isbn") %>' /> 
      </td> 
      <td> 
       <asp:Label ID="bd_titleLabel" runat="server" Text='<%# Eval("bd_title") %>' /> 
      </td> 
     </tr> 
    </ItemTemplate> 
    <LayoutTemplate> 
     <table runat="server"> 
      <tr runat="server"> 
       <td runat="server"> 
        <table ID="itemPlaceholderContainer" runat="server" border="0" style="">

         </tr> 
         <tr ID="itemPlaceholder" runat="server"> 
         </tr> 
        </table> 
       </td> 
      </tr> 
      <tr runat="server"> 
       <td runat="server" style=""> 
        <asp:DataPager ID="DataPager1" runat="server" QueryStringField="pid"> 
         <Fields> 
          <asp:NextPreviousPagerField ButtonType="Link" ShowFirstPageButton="True" 
           ShowNextPageButton="False" ShowPreviousPageButton="False" /> 
          <asp:NumericPagerField /> 
          <asp:NextPreviousPagerField ButtonType="Link" ShowLastPageButton="True" 
           ShowNextPageButton="False" ShowPreviousPageButton="False" /> 
         </Fields> 
        </asp:DataPager> 
       </td> 
      </tr> 
     </table> 
    </LayoutTemplate> 
    <SelectedItemTemplate> 
     <tr style=""> 
      <td> 
       <asp:Label ID="bd_book_codeLabel" runat="server" 
        Text='<%# Eval("bd_book_code") %>' /> 
      </td> 
      <td> 
       <asp:Label ID="bd_isbnLabel" runat="server" Text='<%# Eval("bd_isbn") %>' /> 
      </td> 
      <td> 
       <asp:Label ID="bd_titleLabel" runat="server" Text='<%# Eval("bd_title") %>' /> 
      </td> 
     </tr> 
    </SelectedItemTemplate> 
</asp:ListView> 

QueryStringField =“pid”会做魔术。
