Hello,
I tested the OnClientPasteHtml event and the onpaste events in Firefox 9 and verified that both events are fired in this browser.
<script type="text/javascript">
var maxTextLength = 30;
var messageText = 'You are not able to type more than ' + maxTextLength + ' symbols!';
function isAlphaNumericKey(keyCode) {
if ((keyCode > 47 && keyCode < 58) || (keyCode > 64 && keyCode < 91)) {
return true;
}
return false;
}
function LimitCharacters(editor) {
editor.attachEventHandler("keydown", function (e) {
e = (e == null) ? window.event : e;
if (isAlphaNumericKey(e.keyCode)) {
textLength = editor.get_text().length;
if (textLength >= maxTextLength) {
alert(messageText);
e.returnValue = false;
return false;
}
}
});
}
function CalculateLength(editor, value) {
var textLength = editor.get_text().length;
var clipboardLength = value.length;
textLength += clipboardLength;
return textLength;
}
function OnClientPasteHtml(editor, args) {
var commandName = args.get_commandName();
var value = args.get_value();
if (commandName == "PasteFromWord"
|| commandName == "PasteFromWordNoFontsNoSizes"
|| commandName == "PastePlainText"
|| commandName == "PasteAsHtml"
|| commandName == "Paste") {
var textLength = CalculateLength(editor, value);
if (textLength >= maxTextLength) {
alert("You are not allowed to enter more that 30 symbols");
args.set_cancel(true);
}
}
}
</script>
<telerik:RadEditor id="RadEditor1" OnClientPasteHtml="OnClientPasteHtml" OnClientLoad="LimitCharacters"

<script type="text/javascript">
var limitNum = 250;
var message = 'You are not able to type more than ' + limitNum + ' characters!';
var counter = $get('counter');
function LimitLength(mode)
{
var rtfEditor = $find("<%=RadEditor.ClientID %>");
if (mode == 2){
var oValue = rtfEditor.get_textArea().innerHTML.trim().length;
}
else{var oValue = rtfEditor.get_html(true).trim();}
if (oValue.length >= limitNum)
{
rtfEditor.set_html(oValue.substring(0, limitNum - 1));
alert(message);
}
counter.innerHTML = "Characters left: " + ( limitNum - oValue.length );
}
function AttachHandlers(mode)
{
var rtfEditor = $find("<%=RadEditor.ClientID %>");
if(mode==1)
{
rtfEditor.attachEventHandler("onkeyup", LimitLength);
rtfEditor.attachEventHandler("onpaste", LimitLength);
rtfEditor.attachEventHandler("onblur", LimitLength);
}
else
{
var textarea = rtfEditor.get_textArea(); //returns a reference to the textarea in Html mode
if(window.attachEvent)
{
textarea.attachEvent("onkeydown", LimitLength);
textarea.attachEvent("onpaste", LimitLength);
textarea.attachEvent("onblur", LimitLength);
}
else
{
textarea.addEventListener("keyup",LimitLength, true);
textarea.addEventListener("paste", LimitLength, true);
textarea.addEventListener("blur", LimitLength, true);
}
}
}
function OnClientLoad(editor, args)
{
rtfEditor = editor;
AttachHandlers(1);
LimitLength(1);
editor.add_modeChange(function(sender, args)
{
var mode = sender.get_mode();
if (mode == 1 || mode == 2)
{
AttachHandlers(mode);
LimitLength(mode);
}
});
}
</script>
My suggestion is to install the latest version of Telerik.Web.UI.dll and test again. It is Q3 2011 SP1 (2011.3.1305).
