IE11 & RadTextBox

[Daniel]

Hi, I've come across a bug, I think, with IE11 and RadTextBox. If I set the properties to MultiLine with a MaxLength (of any length) I am unable to paste into that input. It works fine on IE10 and below and also okay on FireFox and Webkit. Thanks. Daniel.

Hi, you can replicate the problem, under Windows 8.1 with IE11, by going to the RadTextBox Input demo and "Set Max Length" and then try to paste something into the Multi-line. Thanks. Daniel.

Hi Daniel,

Thank you for contacting Telerik support.

Unfortunately I have to confirm that this is an issue caused by changes introduced by Microsoft to IE11 and the API it uses. I have forwarded your report to our development department and they will be working on fixing this browser related behavior.

Until this limitation gets fixed there is a workaround and it is using the following JavaScript function on your page:

<script type="text/javascript">
   Telerik.Web.UI.RadInputControl.prototype._onTextBoxPasteHandler_ = Telerik.Web.UI.RadInputControl.prototype._onTextBoxPasteHandler;
            Telerik.Web.UI.RadInputControl.prototype._onTextBoxPasteHandler = function (e) {
                if ($telerik.isSafari || document.selection) {
                    this._onTextBoxPasteHandler_(e);
                }
            }
</script>

Make sure it is defined in <script> tags with the correct type ("text/javascript") set – as shown in the code snippet.

Give this approach a try and let us know how it goes.
