Hello Guys

I created a WebForm in Visual Studio. I would like to show a question (Text: "Are you sure, you want to delete this datarecord?" -Yes - No - Cancel) after clicking the button "buttonDelete".

Is it possible to do this?


I appreciate every help.

推荐答案

最简单的方法是使用HTML元素的事件 onsubmit 形式。请参阅，例如：

http://www.w3schools.com/js/js_form_validation。 asp [ ^ ]。



如您所见，如果处理程序返回false，则不会提交表单。您可以通过询问用户确认来实现此验证。获得用户确认的最简单方法是使用JavaScript 弹出 确认框。它会询问确定/取消问题，这实际上就是你要做的事情：

http://www.w3schools.com/js/js_popup.asp [ ^ ]。



你可以做更多花哨和定制的事情。首先，您可以将jQuery Dialog与模态确认一起使用： http://jqueryui.com/ dialog / #modeal-confirmation [ ^ ]。



如果您需要学习jQuery（强烈推荐），请参阅：

http://en.wikipedia.org/wiki/JQuery [ ^ ]，

http://jquery.com [< a href =http://jquery.com/target =_ blanktitle =New Window> ^ ]，

http://learn.jquery.com [ ^ ]，

我想我列出了所有你需要的元素。有问题吗？

The simplest way which comes to mind is using the event onsubmit of the HTML element form. Please see, for example:
http://www.w3schools.com/js/js_form_validation.asp[^].

As you can see, if the handler returns false, the form will not be submitted. You can implement this "validation" by asking a user confirmation. The simplest way to get a confirmation of the user would be using JavaScript popup confirm box. It will ask an OK/Cancel question, and this is actually what you are trying to do:
http://www.w3schools.com/js/js_popup.asp[^].

You can do anything more fancy and customized. First of all, you can use jQuery Dialog with a modal confirmation: http://jqueryui.com/dialog/#modal-confirmation[^].

If you need to learn jQuery (highly recommended), please see:
http://en.wikipedia.org/wiki/JQuery[^],
http://jquery.com[^],
http://learn.jquery.com[^],
http://learn.jquery.com/using-jquery-core[^],
http://learn.jquery.com/about-jquery/how-jquery-works[^] (start from here).

I think I listed all the elements you need. Any questions?

如果您使用的是jquery ..

http://jqueryui.com/dialog/#modal-confirmation [ ^ ]

If you are using jquery ..
http://jqueryui.com/dialog/#modal-confirmation[^]

我发现了另一种不使用javascript的解决方案或像其他解决方案一样jquery。

I found another solution without using javascript or jquery like the other solutions.

<asp:button id="_buttonDelete" runat="server" onclick="ButtonDeleteClick" text="Delete" cssclass="btn" onclientclick="return confirm('Sure you want to delete this datarecord?');" xmlns:asp="#unknown" />

此代码是我所寻找的，它显示两个按钮确定和取消。单击确定按钮后，您将进入ButtonDeleteClick功能。

This code is all I was looking for, it shows two buttons "OK" and "Cancel". After clicking the button "OK" you'll get to the function "ButtonDeleteClick".

OnClientClick="return confirm('Sure you want to delete this datarecord?');"
