RadTextBox Multiline Maxlength issue back on latest version

[Philip]

<telerik:RadTextBox ID="txtTest" runat="server" TextMode="MultiLine" Width="99%" Height="200px"
  MaxLength="1000" Skin="Windows7">
  <ClientEvents OnValueChanged="RegExpCheck" OnValueChanging="RegExpCheck" OnKeyPress="kp" />
</telerik:RadTextBox>

We previously have code using the RadTextBox on multi-line and limiting user input to 1000 characters. This has been working on version 2011.2.712.40. However we got a couple of users complaining that the field gets 'slow' when accepting user input. Users are using IE browser version 7/ 8. Those using IE 9 are fine. Upon testing with the latest version (2012.2.607.40), the 'slowness' issue got resolved, however, the maxlength value is now being ignored.

Please review and let me know if there is a fix for this. Thanks.

Hello Philip,

In 2012.2.607 version there was a bug with the max length, and we fixed it a bit later. So I tested the code without the client events, since I don't have their code:

<telerik:RadTextBox ID="txtTest" runat="server" TextMode="MultiLine" Width="99%"
    Height="200px" MaxLength="1000" Skin="Windows7">
    <ClientEvents />
</telerik:RadTextBox>

And and the max length is working correct with the 2012.2.710 version. Update your project and please confirm that there is no some JavaScript error in the handlers that prevents JS to execute correctly.

Kind regards,

Hi Lalu,

Different browsers count new line as one or two characters "\n" or "\r\n". Since there is no MaxLenght standard for textarea, we could not do solution that to be consistent in each browsers. We count the new line as 1 character. By default, you can override the _escapeNewLineChars using this code if you like to count them as 2 chars.

Telerik.Web.UI.RadInputControl.prototype._escapeNewLineChars_org = Telerik.Web.UI.RadInputControl.prototype._escapeNewLineChars;
Telerik.Web.UI.RadInputControl.prototype._escapeNewLineChars = function (text, replaceWith)
{
 return this._escapeNewLineChars_org(text, "  ");
}

Hi,
can i set this prperty from server side dynamically.Please let me know this asap.

[Vasil]

Hello Lalu,

You can not apply it server side. It is client side approach because it affects the JavaScript that is running in the browser to validate the text lengthl

I have a custom control of multiline text box.That control is used in all forms.To place the script in custom control is not possible.Because that script needs radcode block.Any other way to use this script to set enter key character as 2 in script.
Thanks

Hello Lalu,

There are some other options:

• Use the latest version.
• Modify the original code and compile the controls. (No sue about your license, and if you have the code) .
• Disable the embedded resources, and include changed with the fix resources. (You will not able to use the CDN)
• Place the script in your master page. (add check if Telerik.Web.UI.RadInputControl.prototype is not a null, to avoid exception when there is no RadInput control in your page)

Hello Franck,

Test with the latest internal build. We did some fixes for this issue. Per my tests it work correct during paste as well as typing and drag-drop. If you have any problems, let us know, so we can correct it the next release.

Testing multiline RadTextBox set to 1000 characters, and if I paste in a block of text, keep hitting CTRL-V, I can paste as much as I want.  IE 8.  The MaxLength doesn't seem to work.....I guess I'll have to truncate it to avoid a DB error.

Hi Dave,

I tested this in the latest version of our control, here in our demos. I would suggest you to upgrade if you are using old version of the controls.
Please note that this is still only client side validation and it is possible for user to turn off the JS and baypass the max length limit of textarea. So you should do server side validation in any case.

hi Vasil,

what is said in these pages(ie11 problem) did not work for me,

Hi,

Did you tried this approach disused in the bottom of the thread:

.RadInput textarea { white-space: pre !important; }

[collapse]

yes I've tried but did not work

[collapse]

with this trick,
ie11 is working properly, but also lower versions looks corrupted

[Vasil]

Hi,

You could download the latest internal build, where the issue is already fixed. If you want, you could use this workaround:

span.RadInput textarea { white-space: pre-wrap; }
