this to display the grid (depends upon the radio value)

function callback2()

        if (req.status == 200)
        {
            mygrid2.clearAll(false);
            mygrid2.loadXML('<%=appPath%&gt;/tsp/xml/gridpal3.xml');
            mygrid.clearAll(false);
            mygrid.loadXML('<%=appPath%&gt;/tsp/xml/gridpal.xml');
            
        }
    }
}

Problem is if select radio continuously grid value is not changing or refresing continuously. if there is no value for particular radio means(selecting query depends upon the radio(vendorid) , last selected radio's values in the grid itself displaying.

Please suggest me to refresh or to delete the xml file and to recreate the file depends upon the option selected from the radio button.  (checked by giving destructor method) no use.
Expecting reply @ the earliest

>>Please suggest me to refresh or to delete the xml file and to recreate the file depends upon the option selected from the radio button.  (checked by giving destructor method) no use.

Basically the best approach is to use some kind of server side script instead of static XML file
Such server side script may generate necessary XML contents based on current environment ( radio button states or some other params )
