I don't think that's possible. It is, however, possible to intercept validation by setting <code>OnClientClick</code> on the controls that do postbacks. Then you can check the global JavaScript variable <code>Page_IsValid</code> for the validation result.

One thing to keep in mind is that, when there are no validators on a page, <code>Page_IsValid</code> will be undefined.

blocks|key|333990|text|您需要调用javascript函数Page_ClientValidate()来启动连接到页面控件的ASP.NET验证。调用此函数后，将正确设置Page_IsValid布尔值。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|333991|下面是我如何使用它的一个例子。如果ASP.NET验证成功，我将禁用该按钮，否则该按钮将保持启用状态，并向用户显示验证摘要。按钮来自ASP：OnClientClick控件。|333992|OnClientClick="javascript:Page_ClientValidate();+if+(Page_IsValid==true)+{+this.disabled=true;+}"|code-block|syntax|javascript|333993|entityMap^0|H|L|1Z|C|0|1X|D|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@$9|P|A|Q|B|C]|$9|R|A|S|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|T|8|@$9|U|A|V|B|C]]|D|@]|E|$]]|$1|H|3|I|5|J|7|W|8|@]|D|@]|E|$K|L]]|$1|M|3|-4|5|6|7|X|8|@]|D|@]|E|$]]]|N|$]]

You will want to call the javascript function <code>Page_ClientValidate()</code> to initiate the ASP.NET validation wired to your page controls. Once this is called, the <code>Page_IsValid</code> boolean value will be properly set.

Here is an example of how I am using it. If ASP.NET validation is successful, I disable the button, otherwise the button remains enabled and the validation summary is displayed to the user. The <code>OnClientClick</code> is from a ASP:Button control.

<pre><code>OnClientClick="javascript:Page_ClientValidate(); if (Page_IsValid==true) { this.disabled=true; }"
</code></pre>

blocks|key|169876|text|我开始通过@EverettEvola来实现这个解决方案，但也会多次调用验证逻辑并显示多个ValidationSummary弹出窗口。我的解决方案如下：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|169877|在按钮上(在我的例子中，按钮是一个提交按钮)|169878|OnClientClick="return+CustomValidationOnClick()"|code-block|syntax|javascript|169879|和CustomValidationOnClick()|169880|function+CustomValidationOnClick(source,+args)+{

I started to implement the solution by @EverettEvola but also where the validation logic was being called multiple times and displaying multiple ValidationSummary popups. My solution was as follows:

On the button (in my case the button was a submit button)

<pre><code>OnClientClick="return CustomValidationOnClick()"
</code></pre>

And the CustomValidationOnClick() 

<pre><code>function CustomValidationOnClick(source, args) {

 //Manually kickoff page validation
 //This call will display the Validation summary popup if page is invalid
 Page_ClientValidate();

 //Page_IsValid set by the result of the Page_ClientValidate() call
 if (Page_IsValid == true) {
 this.disabled=true;
 return true; //if Submit button return true to continue form submit
 }
 else {
 //do whatever here
 return false; //if Submit button return false to cancel form submit
 }
}
</code></pre>

i have a validationSummary in my page. i want to call a javascript function after the validationSummary is filled. how can i achieve this? 

i think i should add an attribute in the code behind, but i can't figure out what is the attribute's key. 

any help?

how can i call a javascript function when an ASP.net validation summary is filled

我的页面中有一个validationSummary。我想在填充validationSummary之后调用一个javascript函数。我如何才能做到这一点？我想我应该在后面的代码中添加一个属性，但是我不知道属性的键是什么。有什么帮助吗？
