推荐答案

因为你没有使用数据源控件 [ ^ ]，你没有使用新的.NET 4.5模型绑定功能 [ ^ ]，你需要为每个网格提供一个 DataSource 页面索引更改的时间。 通常，代码看起来像这样： Since you're not using a data source control[^], and you're not using the new .NET 4.5 model binding features[^], you need to provide the grid with a DataSource every time the page index changes. Typically, the code would look something like this: protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { BindGrid(); } } protected void Grid1_PageIndexChanging(object sender, GridViewPageEventArgs e) { Grid1.PageIndex = e.NewPageIndex; BindGrid(); } private void BindGrid() { Grid1.DataSource = LoadSomeDataHere(); Grid1.DataBind(); }
