title: JQGrid, Search related issue
body: <p>Is there anyway to validate the search field (I'm using custom search) before sending request to server? Validation is working fine with row editing and adding mode. Let say I want to search column price and error message should occur when user enters a text in search field.
  If search returns no data, I want to post a message on the screen. I see no events in search function that can get the server response. The onClose event happened when the search box is closed, but I don't know how to get the server response from this?</p>
  
  <p>Another question, I've tried to use gridResize but it's not working,  everything else is working just fine, I see no resize icon in bottom right corner. Please take a look at my code below:</p>
  
  <blockquote>
    <p>jQuery("#list").jqGrid('gridResize',{minWidth:350,maxWidth:800,minHeight:80,
    maxHeight:350});</p>
