亲爱的所有人，

正在使用asp.net，c#，SqlServer2005.

我有一个Gridview充满了成千上万的记录.而且我也为此做了分页.

就像1 2 3 4 5 6 7 8 9 10 ........... 500

在gridview下方，它必须显示标签消息您正在查看第2页(共100页).

我需要通过编码来实现.

推荐答案

在此示例中，我将"ProductInfo"类用于GridView数据源，将"dtgView"用于我的GridView，将"lblPageInfo标签"用于显示页面信息.您需要GridView AllowPaging ="True"并生成OnPageIndexChanging ="dtgView_PageIndexChanging"事件以分页GridView. br/>
然后需要在页面上将GridView绑定到下面的代码中:

here an example i use "ProductInfo" class for GridView DataSource, "dtgView" my GridView and "lblPageInfo Label for display page information. You need to GridView AllowPaging="True" and generate OnPageIndexChanging="dtgView_PageIndexChanging" Event for paging your GridView.

then need to Bind GridView on page load code below:

protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                List<productinfo> list = new ProductInfo().SelectAll4Grid();
                // Collection of Product.
                dtgView.DataSource = list; 
                dtgView.DataBind();
                lblPageInfo.Text = "you are viewing page 1 of " + dtgView.PageCount.ToString();
                // Display Page Information.
            }
        }
</productinfo>

那么您需要在页面索引更改事件上绑定GridView并在下面收集您的页面信息代码:

then you need to Bind GridView on page index changing event and collect your page information code below:

protected void dtgView_PageIndexChanging(object sender, GridViewPageEventArgs e)
        {
            List<productinfo> list = new ProductInfo().SelectAll4Grid();
            dtgView.PageIndex = e.NewPageIndex;
            lblPageInfo.Text = "you are viewing page " + (e.NewPageIndex + 1).ToString() + " of " + dtgView.PageCount.ToString();
            // Page Index Start from 0 so we need +1
            dtgView.DataSource = list;
            dtgView.DataBind();
        }
</productinfo>

它正在我的项目上.尝试使用它.

it''s working on my project. try use it.
