get_value() issue

[Bernard]

Hello,
I have upgraded the telerik version from 2011-02 to 2012_03.

In my code behind, I set the ClientEvents.OnKeyPress value. Until the upgrade, it worked very well. But since it doesn't. it seems that the get_value() needs a delay to return the value. If I replace the get_value by document.getElementById, it works...

I would rather like to use the get_value() function.
Thanks for help...

saisie.ClientEvents.OnKeyPress = @"enterSaisie2";

function pageLoad()
        {
           textSaisie = $find("<%=saisie.ClientID %>");
        }
function enterSaisie2(e)
        {
           if (window.event.type == "keypress" && window.event.keyCode == 13)
           {
                try
                {
                    aSaisie = new String(textSaisie.get_value());
                                   // etc...

Hi Bernard,

Please take a look into the following code snippet I tried with RadTextBox, since  you havent specified which control you are using. During the OnKeyPress event the value is still not updated, therefore, sender.get_value() will return the old one. So if you want to get the newly typed value from the RadTextBox on OnKeyPress event, please try the following.

ASPX:

<telerik:RadTextBox ID="TextBox1" runat="server" Text="old value" onKeyPress="return enterSaisie2(event);"></telerik:RadTextBox>

JavaScript:

<script type="text/javascript">
    function enterSaisie2(e) {
        if (window.event.type == "keypress" && window.event.keyCode == 13) {
            textSaisie = $find("<%=TextBox1.ClientID %>");
           // you will get the old value in TextBox here
           var aSaisie = textSaisie.get_value();

          // you will get the newly typed value here
          var aSaisie = textSaisie.get_element().value;
        }
    }
</script>

Thanks,
Princy.

Hello Princy,

Many thanks for your answer. Sorry not to have specified the control. You guessed that it was a RadTextBox.

But if I understand, the behaviour of this function has changed. Otherwise it wouldn't have worked with the previous version.
Anyway, your explanation is clear. So I'm going to do like you advocate.
Have a good day...
Bernard
