  Hey guys,
  
  We have used a RadTextBox in our master page for search. I want to disable a particular button based on the string present in the box or not. I have used below javascript which I call on the keyup event of the RadTextBox. However it is not returning a proper value of characters present in the RadTextbox while I am typing in it. If I enter a letter "a" it returns me nothing. But if I further type "b" then it returns me "a". So it returns my typed word - last character. Such is not the case with the normal asp textbox.
  The reason being that I am using ClientID property of the RadTextBox. It is rendered as below.
  

  <span id="txtSearch_wrapper" class="RadInput RadInput_Default" style="white-space:nowrap;">

          <input type="text" size="20" id="txtSearch_text" name="txtSearch_text" class="riTextBox riEnabled" onkeyup="disableSearchButton();" style="width:125px;" />

          <input id="txtSearch" name="txtSearch" class="rdfd_" style="visibility:hidden;margin:-18px 0 0 -1px;width:1px;height:1px;overflow:hidden;border:0;padding:0;" type="text" value="" />

            <input id="txtSearch_ClientState" name="txtSearch_ClientState" type="hidden" />

  </span>

  I need the "txtSearch_text" as ClientId, however the code is returning "txtSearch". Is there any way I can do that.
  
  

  function disableSearchButton() {

              var searchButton = document.getElementById("<%= txtSearch.ClientID %>");

              alert(searchButton.value);

          }

  <telerik:RadTextBox ID="txtSearch" EnableViewState="false" onkeyup="disableSearchButton();" runat="server" />

  
  Note: Do not worry about the getElementById() that I am using to get the reference to the search box in javascript. I am pretty much sure it is correct.
  
  Thanks,
  Manoj

  Hello Manoj,
  
  Please use the following code in order to achieve the desired functionality:
  

  function disableSearchButton() {

      var searchButton = $find("<%= txtSearch.ClientID %>");

      alert(searchButton.get_textBoxValue());

  }

  
  I hope it helps.
