How to identify checkboxes of a specific column in a grid using javascript
<p>i already posted this question.Sorry that i failed to add any code.That thread is closed. Apologies. I'm bothering you all again. </p>

<p>Anyways, i just want to identify checkboxes of a specific columns in a radgrid? i have two columns. and two buttons.if i click one button i need to check/uncheck checkboxes of that particular column alone.Kind help please?i already tried this. Now all checkboxes in the grid are getting checked/unchecked.</p>

<p>Please find the code below.</p>

<pre><code>var inputs = document.getElementsByTagName("input"); //or document.forms[0].elements;

   for (var i = 0; i &lt; input.length; i++) 
   {
       if (input[i].type == "checkbox") 
       {
           if (input[i].checked) {
               input[i].checked = false;
           }
           else
