为什么lnkbtnlike.visible = false在ASP.NET C＃实体框架中没有工作onclick事件？ [英] Why lnkbtnlike.visible = false is not working onclick event in ASP.NET C# entity framework?
本文介绍了为什么lnkbtnlike.visible = false在ASP.NET C＃实体框架中没有工作onclick事件？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
问题是，当我点击LnkbtnLike的OnClick事件时，属性lnkbtnLike.visible = false无法正常工作。我调试代码并检查其值，它成功地取值false但是当点击事件后页面加载lnkbtnLike仍然可见为true。我无法理解为什么会发生这种情况？
我也在该页面上使用了转发器控件，但这些链接按钮不在重新开始。我想可能是因为转发器控制lnkbtnLike可见属性不起作用..请让我清楚这一点。谢谢！
我的尝试：
The Problem is when i click OnClick event of lnkbtnLike the property lnkbtnLike.visible = false is not working. i debug the code and check its value , it successfully takes the value false but when page loads after click event lnkbtnLike is still visible to true. I can't understand why this is happening?
I am also using a repeater control on that page but these link buttons are out of reapeater body . I Think may be because of repeater control lnkbtnLike visible property is not working.. Please let me clear this. Thank you !
What I have tried:
<div class="row">
<div class="col-sm-12">
<asp:Label ID="lblLike" runat="server"></asp:Label>
<asp:LinkButton ID="lnkBtnLike" runat="server" Style="color: darkgray" OnClick="lnkBtnLike_Click">Likes</asp:LinkButton>
<asp:LinkButton ID="lnkBtnUnlike" runat="server" OnClick="lnkBtnUnlike_Click" Visible="false">Liked</asp:LinkButton>
<asp:Label ID="lblComment" runat="server"></asp:Label>
</div>
</div>
<asp:Panel ID="Panel1" runat="server">
<div class="row">
<asp:Repeater ID="rptComment" runat="server">

推荐答案
Response.Redirect(Request.Url.AbsoluteUri, false);
由于您将事件重定向到同一页面，因此会重新加载页面。因此可见性将设置为默认值。尝试删除该行并检查。
Since you are redirecting the event to the same page, it reloads the page. so the visibility will set to the default value. try removing the line and check.
