I was running on a bit older version of telerik, but now I upgraded to the most resent version get_value() on radtextbox don't work anymore! 

<telerik:RadTextBox ID="txtRecherche" runat="server" Width="335px" style="margin: 10px 0px;"
            onkeyup="visibilite()"></telerik:RadTextBox>
 
 
 <script type="text/javascript">
        function visibilite() {          
            var chaine = $find("<%= txtRecherche.ClientID %>").get_value();
      }
 
</script>

get_value always return an empty string except when make the focus on another control and then I return in this one.

Hi Tommy,

On onkeyup event the value is still not updated, since it is not applied. The new value gets applied on blur/pressing enter or using set_value client side method.
Before applying the new value, it is considered just as DisplayValue (which can be EmptyMessage/ ErrorMessage/ Formated Text. etc.)

You can still access this text using get_textBoxValue() property during the keyup event. And you can force the control to consider this as actual value using textbox.set_value(textbox.get_textBoxValue());

Thanks Vasil.
I was having issues with this, i had to check for a textBox' s content.
On my side i can't do
someTextBox.set_value(someTextBox.get_textBoxValue());
because this will set the empty text value to the actual value. This will let my validation pass, which shouldnt.
What i did is this:
if($.trim(someTextBox.get_textBoxValue()) == '' || $.trim(someTextBox.get_textBoxValue()) == someTextBox.get_emptyMessage())
{
  alert('Empty');
}
else
{
  alert('Has content.');
}
And this works like a charm :)

THANK YOU!

 So I can NOW avoid passing the EmptyMessage to a popup window...

 

 

  var oInput = document.getElementById('<%= tbNotes.ClientID %>');
            var oText = "";
            var emptyMessage = $find("<%= tbNotes.ClientID %>").get_emptyMessage();
            //'value' will send the EmptyMessage if nothing has been typed, which we do not want to see in the popup, so we null it out.
            if (oInput && (oInput.value !== emptyMessage)) {
                oText = oInput.value;
            }‚Äč
