I have a RedEditor with the ID radEditor1 and the following javascript function:
// Character and Word Counter for Telerik RadEditor
//   Parameters:
//     ID of the RadEditor
//     Maximum number of words allowed
//     Returns false if maxWords is exceeded, true otherwise
 
function LimitWordCount(editorId, maxWords)
{
    var content = $find(editorId).get_text();
    var words = 0;
    var chars = 0;
    LimitWordCount = true;
    if (content) {
        punctRegX = /[!\.?;,:&_\-\-\{\}\[\]\(\)~#'"]/g;
        content = content.replace(punctRegX, "");
        if (content) {
            splitRegX = /\s+/;
            var array = content.split(splitRegX);
            words = array.length;
            chars = content.length;
        }
    }
    if (words > maxWords) {
        alert("Cannot exceed maximum word count.  Please shorten text.\nTo undo a paste, click the undo button at the top of the text area.")
        LimitWordCount = false;
    }
}

I call this function from the following link in a formview:
<asp:LinkButton ID="UpdateButton" runat="server" CausesValidation="True" CommandName="Update" Text="Save" CssClass="linkbutton" OnClientClick='LimitWordCount("RadEditor1", 30)' />

When the javascript is hit, $find(editorId) returns null.

How would I get the text in this instance?  I have tried all the examples I can find, but all return null or give some other error. 

Help is appreciated!

Hello,

I tested the provided code/markup and I was unable to reproduce the problem. You can see my test in the following video: http://screencast.com/t/YYjCwX8KCp. Am I missing something?

Please, test the attached project and if it works use it as a base to implement your scenario.

Best regards,
