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并asp:DataPager喜欢我发现的一些示例，但是分页使用 javascript 并且我希望分页将是友好的。

我怎样才能把我的一些代码？

[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>

这是后面的代码：

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，如果我从中学习，我将不胜感激。我发现的所有示例都是针对 SQL 的，并且我的数据需要处于可访问状态。

这是一个 asp listview 示例，您必须按如下方式定义查询字符串。

    <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"

    </SelectedItemTemplate>
</asp:ListView>

QueryStringField="pid" 会变魔术。
