Sounds like you're trying to mix Ajaxified properties and DOM element properties. Leave the property Enabled = "True" when you ajaxify it, then use JS on page load to btnSend.disabled = true it. If you use pure js to disable it the function you have above should work fine to re-enable it. For example, if the ajaxify property 'Enabled' is set to true, then place the following javascript into your page:

window.onload = function(){
    document.getElementById("btnSend").disabled = true;
};

Then use the function you wrote above to enable it onkeyupontextbox(). Because javascript is disabling the button, it should be able to re-enable it. Before, you were disabling with the Ajaxified property and trying to re-enable with js.

Could following be the answer? (Dont have experiences with RadAjaxmanager)

function EnableBtnSend()
 {
    $find("<%=btnSend.ClientID %>").ajaxRequest("");
 }
