Validate Control using javascript
<p>I have asp.net web application where controls are getting loaded dynamically on the web page. Lets say I have a comboBox in my aspx page and on value change event of the ComboBox I am doing Postback. ComboBox is having validator associated with it. Also there are other controls in the web page with validators.</p>

<p>I want to validate the comboBox control before I do postback. I am using the following javascript to do so</p>

<pre><code>  function(s, e)
{ 
    if (typeof (Page_ClientValidate) == 'function') 
    { 
        Page_ClientValidate(); 
        if (!Page_IsValid) { return; } 
        Callback.PerformCallback();LoadingPanel.SetText(settingCtlPropText); LoadingPanel.Show(); 
    }
    else
    {
        Callback.PerformCallback();LoadingPanel.SetText(settingCtlPropText); LoadingPanel.Show(); 
    }
}
</code></pre>

<p>But this java script is validating the comboBox along with the other controls in the page. 
I want to validate ONLY comboBox and not other controls when any value chanded in the comboBox , before I do postback.</p>

<p>How can I achieve this ??</p>
