title: Find textbox in gridview in JQuery
body: <p>I have a gridview which contains image buttons. On click of that image button, another grid gets filled which contains some textboxes. I want to fire JQuery validation for those textboxes on lost focus if the value inserted in textbox is greater than one of the column value of gridview. That column value is using bound field to bind data.</p>
  
  <p>How can I achieve this using Jquery? I am new in JQuery.</p>
  
  <p>I have tried something like this.</p>
  
  <pre><code>&lt;script type="text/javascript" language="javascript"&gt;
      $(function () {
  
          var GridView = $('#grdSalesOrder tr').each(function () {
              var btn = $(this).find('img[id*=imgdesign1]');
              alert(btn);
          });
  
      });
  &lt;/script&gt;
  </code></pre>
  
  <p>First I am finding the main gridview and imagebutton of that grid view. When button is clicked, another gridview gets filled. So i think I should write code to find another grid on click event of this image button because at the time of page load event, another grid will not be available. But in this code I am not getting the button which is there in main grid view. Plz edit my Jquery if I am making any mistake.</p>
