So, I have never seen such constructions in HTML

<pre><code>&lt;%= ddlConviction.ClientID %&gt;
</code></pre>

It's looks like scriplets on server side and on the client it should be transformed into something different.

I think you have a JS error on the page, because JS can't find 

<pre><code>&lt;%= ddlConviction.ClientID %&gt;
</code></pre>

and your 

<pre><code>txtConDetail 
</code></pre>

for example is NULL, so the construction 

<pre><code>txtConDetail.disabled
</code></pre>

will cause the error.

Try to use DevTools in Chrome or FireBug in FireFox, also see the page source in browser.

disable your validators when you don't need textboxed to be required:

<pre><code>function DisableEnable2() {

 var ddlCnovict = document.getElementById("&lt;%= ddlConviction.ClientID %&gt;")
 var txtConDate = document.getElementById("&lt;%= txtConvictDate.ClientID %&gt;")
 var txtConDetail = document.getElementById("&lt;%= txtConvictionDetails.ClientID %&gt;")

 var txtConDateValidatior = document.getElementById("&lt;%= txtConvictDateValidatior.ClientID %&gt;")
 var txtConDetailValidatior = document.getElementById("&lt;%= txtConvictionDetailsValidatior.ClientID %&gt;")

 if (ddlCnovict.options[ddlCnovict.selectedIndex].text == "No") {
 ValidatorEnable(txtConDateValidatior, false);
 ValidatorEnable(txtConDetailValidatior, false);
 txtConDate.disabled = true;
 txtConDetail.disabled = true;
 }

 else {
 ValidatorEnable(txtConDateValidatior, true);
 ValidatorEnable(txtConDetailValidatior, true);
 txtConDate.disabled = false;
 txtConDetail.disabled = false;
 }


}

I know there are validations by the author's comment response:

Instead of disabling the control use the attribute function to add the disable attribute:

txtConDate.Attributes.Add("disabled","true");

and on selecting "YES" do this,

txtConDate.Attributes.Clear("disabled");

I am facing a strange programming problem. 

I've a page for user registration. 
I am using JavaScript code to disable text boxes when user selects no from option.

But after the selecting Option 'No' from drop down list, page is not getting submitted and not redirecting to next page. 

And surprisingly, if I select every 'Yes' &amp; fill text box, then it submits smoothly and redirect to next page. 

I suspect this is JavaScript problem. Need help please !

<hr>

Here is my javasctipt code sample

function DisableEnable2() {

<pre><code> var ddlCnovict = document.getElementById("&lt;%= ddlConviction.ClientID %&gt;")
 var txtConDate = document.getElementById("&lt;%= txtConvictDate.ClientID %&gt;")
 var txtConDetail = document.getElementById("&lt;%= txtConvictionDetails.ClientID %&gt;")


 if (ddlCnovict.options[ddlCnovict.selectedIndex].text == "No") {

 txtConDate.disabled = true;
 txtConDetail.disabled = true;
 }

 else {
 txtConDate.disabled = false;
 txtConDetail.disabled = false;
 }


 }
</code></pre>

我正面临一个奇怪的编程问题。我有一页可供用户注册。当用户选择no选项时，我使用JavaScript代码禁用文本框。但是，在从下拉列表中选择“No”选项之后，页面将不会被提交，也不会重定向到下一页。令人惊讶的是，如果我选择了“是”和“填充”文本框，那么它就会顺利地提交并重定向到下一页。我怀疑这是JavaScript的问题...
