删除用户后刷新gridview [英] Refresh gridview after I delete a user
问题描述
我有一个GridView，我尝试了不同的方法来刷新它，以便在我点击删除按钮后立即显示结果。我看到结果的唯一一次是手动刷新浏览器。有人可以告诉我为什么gridview不会更新？
任何帮助都将不胜感激..
我尝试过：
<％@ Page Language =C＃AutoEventWireup =trueCodeFile =Administration .aspx.csInherits =AdminPages_Administration％>
<！DOCTYPE html>
< html xmlns =http ：//www.w3.org/1999/xhtml>
< head id =Head1runat =server>
< meta charset =UTF-8/>
< meta http-equiv =X-UA-Compatiblecontent =IE = edge>
< meta name =viewportcontent =width = device-width，initial-scale = 1>
< title> Gridview< / title>
< link href =AdminStyles / AdminStyles.css =stylesheet/>
< / head>
< body>
< form id =form1runat =server>
< asp：ScriptManager ID =ScriptManager1runat =serv呃>
< asp：HyperLink ID =HyperLink1runat =serverNavigateUrl =〜/ Default。 aspxImageUrl =〜/ Images / NFI-Logo.png/>
I have a GridView and I tried different ways to refresh it to show the results right after I click the delete button. The only time I see the results is when I manually refresh the browser. Could someone please let me know why the gridview won't update?
Any help would be appreciated..
