    [CLOSED] Html editor text update

    Hi
    whats the best way to append a text to an html editor.
    The editor is a messaging panel that receives a new message after every 10 seconds and we need also to scroll to the last message that was appended to the editor.

    At the moment I am doing this to append the message.
    editor.setValue(String.format('{0} {1}',editor.getValue() messages));
    But I believe there shoould be a more efficient way of appending new text to the html control

    Hi,

    There is the append method.

    How to scroll please look at the example.

    Example
    <%@ Page Language="C#" %>
 
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Ext.NET Example</title>

    <script type="text/javascript">
        var onUpdate = function (editor) {
            var b = editor.getEditorBody();

            editor.append('new message<br/>');
            b.scrollTop = b.scrollHeight;
        };
    </script>
</head>
<body>
    <form runat="server">
        <ext:ResourceManager runat="server" />
        <ext:HtmlEditor ID="HtmlEditor1" runat="server" />
        <ext:TaskManager runat="server" AutoRunDelay="1000">
            <Tasks>
                <ext:Task Interval="1000">
                    <Listeners>
                        <Update Handler="onUpdate(HtmlEditor1);" />
                    </Listeners>
                </ext:Task>
            </Tasks>
        </ext:TaskManager>
    </form>
</body>
</html>
