Question

我想在我从List创建的网格视图上启用页面索引。

列表如下所示

public class SearchResults
    {
        public string fname { get; set; }
        public string mname { get; set; }
        public string lname { get; set; }

    }

我通过以下方法将数据添加到此列表和GridView中：

SearchResults result= new SearchResults();// Class Variable      
Void Search()
{

result.fname="John";
result.mmane="Cody";
result.lmane="lname";
SearchResults.Add(result);
Gridview1.DataSource=result;
Gridview1.DataBnd();
}

因为，我想为此页面启用分页索引，我为它创建了一个事件，看起来像下面的代码

protected void On_PageIndexChanging(Object sender, GridViewPageEventArgs e)
    {

        GridView1.PageIndex = e.NewPageIndex;
        Gridview1.DataSource=result;
        Gridview1.DataBnd();


    }

即使在页面索引事件中绑定gridview后它也无法正常工作，

对可能发生的事情有所了解？有人可以解释我如何将列表结果绑定到网格视图页面索引？

感谢。

您可以使用以下代码：

public class SearchResults
{
   public string fname { get; set; }
   public string mname { get; set; }
   public string lname { get; set; }
}

在.aspx页面中设置这样的标记：

<asp:GridView runat="server" ID="Gridview1" AllowPaging="True" OnPageIndexChanging="PageIndexChanging" PageSize="4">
    </asp:GridView>

在代码后面编写以下代码（.aspx.cs）：

    protected void Page_Load(object sender, EventArgs e)
    {
      if (!IsPostBack)
      {
         // Get list of search and bind data with Grid
         this.Search();
      }
    }

    private void  Search()
    {
        var searchResults = new List<SearchResults>();
        var search = new SearchResults { fname = "John" };
        searchResults.Add(search);
        search = new SearchResults { fname = "John2" };
        searchResults.Add(search);

        search = new SearchResults {fname = "Micheal" };
        searchResults.Add(search);

        search = new SearchResults { fname = "Sara" };
        searchResults.Add(search);

        search = new SearchResults { fname = "Jenne" };
        searchResults.Add(search);

        search = new SearchResults { fname = "Mac" };
        searchResults.Add(search);

        this.Gridview1.DataSource = searchResults;
        this.Gridview1.DataBind();
    }

    protected void PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        this.Gridview1.PageIndex = e.NewPageIndex;
        this.Search();
    }

在GridView上启用页面索引，将List作为其数据源
