java script

Hi, try to use like this.

document.getElementsById("rdoListSearchOrder").checked

because the way you are trying to use that does bind the value at the runtime but that time control doesnot exist thats y. i think its not very clear.

you can also use your old code this 
document.getElementsByName("<%=rdoListSearchOrder.ClientID %>") [0].checked
after the body tag.

Cause: before loading the asp.net content(or body tag) you are using the the Control in the Head tag, thats y nothing is coming. you can write your javascript function after the body tag that time it will work.

below i placed the sample code it will be useful for you
function getSelectedRadio(buttonGroup) {
   // returns the array number of the selected radio button or -1 if no button is selected
   if (buttonGroup[0]) { // if the button group is an array (one button is not an array)
      for (var i=0; i         if (buttonGroup[i].checked) {
            return i
         }
      }
   } else {
      if (buttonGroup.checked) { return 0; } // if the one button is checked, return zero
   }
   // if we get to this point, no radio button is selected
   return -1;
} // Ends the "getSelectedRadio" function

function getSelectedRadioValue(buttonGroup) {
   // returns the value of the selected radio button or "" if no button is selected
   var i = getSelectedRadio(buttonGroup);
   if (i == -1) {
      return "";
   } else {
      if (buttonGroup[i]) { // Make sure the button group is an array (not just one button)
         return buttonGroup[i].value;
      } else { // The button group is just the one button, and it is checked
         return buttonGroup.value;
      }
   }
} // Ends the "getSelectedRadioValue" function
