Editor Clipboard issue

[Afroz khan]

Hello Team

I am using Telerik RadEditor where I set the max length using JavaScript but when I paste the data from Clipboard to Editor, I gets the message
" Do you want to allow this webpages to access your Clipboards?" if I click Don'tAllow and do the paste again then JavaScript which using to control the max length gets fail and user can paste large amount of data on Editor.

<telerik:RadEditor ContentAreaCssFile="~/Styles/EditorContentAreaCss.css" ID="txtDetails" MaxTextLength="8000"
runat="server" EditModes="Design" EnableResize="false" Height="150px" OnClientLoad="EditorMaxLengthvalidation8000"
OnClientPasteHtml="OnClientPasteHtml8000" NewLineBr="false" NewLineMode="P" Style="border: 1px solid Navy;
background-color: White;" ToolsFile="~/App_Data/RadControls/Editor/ToolsFile.xml"
Width="503px">

<telerik:EditorCssFile Value="~/Styles/Editor.css" />
</CssFiles>
</telerik:RadEditor>


JavaScript

function OnClientPasteHtml8000(editor, args) {
var limitCharacters = 8000;
OnClientPasteHtml(editor, args, limitCharacters);
}

function OnClientPasteHtml(editor, args, limitCharacters) {
try {
var commandName = args.get_commandName();
var value = args.get_value();
var lengthWithOutHtml = 0;
var lengthWithHtml = 0;
var lengthDifference = 0;
var messagePaste = 'Max length exceeded to ' + limitCharacters + ' characters. Content cannot paste.';
lengthWithHtml = value.length;

//This condition raise when user paste only text which does't contains any HTML code.
//So due to this we don't suppose to update the 'value' field.
if (value != "") {
//value = $(value).text();
lengthWithOutHtml = value.length;
lengthDifference = lengthWithHtml - lengthWithOutHtml;
}
if (commandName == "PasteFromWord"
|| commandName == "PasteFromWordNoFontsNoSizes"
|| commandName == "PastePlainText"
|| commandName == "PasteAsHtml"
|| commandName == "Paste") {
var textLength = CalculateLength(editor, value);
var updatelimitCharacters = lengthDifference + limitCharacters;
if (textLength > limitCharacters) {
args.set_cancel(true);
alert(messagePaste);
}
                        
        }
}
catch (e) { }
}

function EditorMaxLengthvalidation8000(editor, args) {
var limitCharacters = 8000;
EditorMaxLengthvalidation(editor, args, limitCharacters);
//Hide the tabbing
HideTabbingInEditor(editor);

}

function EditorMaxLengthvalidation(editor, args, limitCharacters) {
var rtfEditor = editor;
var currentMode = rtfEditor.get_mode();
rtfEditor.set_stripFormattingOptions(Telerik.Web.UI.StripFormattingOptions.NoneSupressCleanMessage | Telerik.Web.UI.StripFormattingOptions.MSWordNoMargins);
AttachHandlers(currentMode, rtfEditor, limitCharacters);
editor.get_contentArea().className = "fs-editor";
   
}

function HideTabbingInEditor(editor) {
editor.removeShortCut("InsertTab");
var buttonsHolder = $get(editor.get_id() + "Top"); //get a reference to the top toolbar zone of the editor
var buttons = buttonsHolder.getElementsByTagName("A"); //get a reference to all A elements on the toolbar and disable the tabbing trough them
for (var i = 0; i < buttons.length; i++) {
var a = buttons[i];
a.tabIndex = -1;
a.tabStop = false;
}
var element = editor.get_element();
editor.get_contentAreaElement().tabIndex = element.tabIndex;
element.tabIndex = -1;
}
