        {

          

                switch (c.GetType().ToString())

                {

                    case "System.Web.UI.WebControls.TextBox":

                        ((TextBox)c).Text = "";

                        break;

                    case "System.Web.UI.WebControls.CheckBox":

                        ((CheckBox)c).Checked = false;

                        break;

                    case "System.Web.UI.WebControls.RadioButton":

<script language="javascript" type='text/javascript'>

 

        function CLSEvent()

        {

              for (i=0; i<document.forms[0].length; i++)

              {

                    doc = document.forms[0].elements[i];

                    switch (doc.type)

                    {

                        case "text" :

                                break;               

                          case "select-one" :

doc.options[doc.selectedIndex].selected = false;

                                break;                     

                          case "select-multiple" :

                                while (doc.selectedIndex != -1)

                                {

                                      indx = doc.selectedIndex;

                                      doc.options[indx].selected = false;

                                }

                                doc.selected = false;

                          default :

                                break;

                    }

</script>

 

 

JQuery:

function clear_form_elements(ele) { 

     $(ele).find(':input').each(function() {  
         switch(this.type) { 

             case 'password': 

              case 'select-multiple': 

            case 'select-one': 

             case 'text': 

              case 'textarea': 

                $(this).val(''); 

                 break; 

             case 'checkbox':
