Paste problem with TextMode="MultiLine" and MaxLength set

[BiBongNet]

Hi,

I have a problem with RadTextBox, version 2012.3.1113.40. I cannot paste into the textbox when setting TextMode="MultiLine" and  MaxLength. This issue happens with IE 10 only.

Thanks.

Hi,

I have upgraded to the version 2012.3.1205.40, the problem still exists.

The console of IE Developer tools display the following error each time Control + V is pressed:

Telerik.Web.UI.WebResource.axd, line 12945 character 2
SCRIPT5007: Unable to get property 'selection' of undefined or null reference

The line 12945 is in bold in the code block below:

try{a=window.clipboardData.getData("Text");
}catch(d){c=false;
}if(c&&a!=""){if(d.preventDefault){d.preventDefault();
}var g=this._textBoxElement.document.selection.createRange();
var f=this._maxLength-this._textBoxElement.value.length+g.text.length;
var b=this._escapeNewLineChars(window.clipboardData.getData("Text"),"%0A").substr(0,f);
g.text=b;
}

Hi,

I tried to replicate the issue on my end in our online examples but to no avail. See the movies below which demonstrates my local test and let me know if I'm missing something.

Hello,

There is an issue with the RadTextBox when setting MultiLine to true and MaxLength when running in IE11.
I get the error on my test page, with is running under .NET 4.5.1 and using Telerik.Web.UI build 2013.3.1114.45

You can reproduce it here in this demo:

http://demos.telerik.com/aspnet-ajax/input/examples/radtextbox/firstlook/defaultcs.aspx

Set MaxLength to 255 for example then try to paste something into the Multi-Line box.  

I get a JavaScript error:  
Line: 474
Error: Unable to get property 'createRange' of undefined or null reference

Hi Gavin,

This seems to be an issue with Internet Explorer 11 due to some changes introduced by Microsoft. Please have a look into this forum thread which deals with the same issue and how to fix that.

Thanks,
Shinu.

Hi Shinu,

Thank you for the prompt response.  The work-around solved the Issue,

[DevTeam]

This workaround did not work for me.

<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>

Error:

JavaScript runtime error: Unable to get property 'prototype' of undefined or null reference



Using Q32013 control set.

Hello Robert,

Please try to download the latest version of the control where the issue is already fixed. Give it a try and verify if it works for you.
