'GridView1'触发了未处理的事件PageIndexChanging

Question

我正在使用gridview，我想使用分页。我已经设置允许分页为true，页面大小为5.我可以在gridview的底部看到数字，但是当我点击一个数字移动到各自的页面时，它会抛出一个错误消息：

The GridView 'GridView1' fired event PageIndexChanging which wasn't handled.

代码：

<asp:GridView ID="GridView1" runat="server" CellPadding="5" 
    AutoGenerateColumns="False" AllowPaging="True" DataKeyNames="contact_id" 
    onrowcancelingedit="GridView1_RowCancelingEdit" 
    onrowediting="GridView1_RowEditing" onrowupdating="GridView1_RowUpdating" 
    PageSize="5"> 
    <Columns> 
     <asp:TemplateField HeaderText="contact_id"> 
      <ItemTemplate> 
       <asp:Label ID="Label3" runat="server" Text='<%# Eval("contact_id") %>'></asp:Label> 
      </ItemTemplate> 
     </asp:TemplateField> 
     <asp:TemplateField HeaderText="name"> 
      <ItemTemplate> 
       <asp:Label ID="Label4" runat="server" Text='<%# Eval("name") %>'></asp:Label>

Answer 1

你将不得不处理PageIndexChanging事件网格

喜欢的东西

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e) 
{ 
    GridView1.PageIndex = e.NewPageIndex; 
    //Bind grid 

} 

Answer 2

你会需要编写 “PageIndexChanging” 事件，使其工作。为PageIndexChanging添加一个事件处理程序，您可以在其中设置GridView.CurrentPage = e.NewPage ...

Answer 3

如果启用了分页，它将不起作用。您还需要为PageIndexChangeEvent编写事件处理程序。检查此链接：http://forums.asp.net/post/1177923.aspx

Answer 4

再添加一个事件在HTML标记为pagging。

OnPageIndexChanging="GridView1_PageIndexChanging" 

现在从代码处理相同的事件背后

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e) 
{ 
    //Your code 
}
