Discovered a problem on the latest editor, latest Firefox. If the editor is initially hidden when loaded, an extra <br> will be added to the existing content.

The behavior does not exist in Chrome or IE. The behavior does not exist in the previous version of the editor that we had (2012.2.724.40)

This is a significant problem for us.  Can you provide a solution?

Thanks,
Trevor.

Hi Trevor,

Unfortunately I couldn't replicate the issue on latest telerik version of  RadEditor in latest FireFox. Please have a look into the sample code snippet which works fine at my end. Please provide a sample code where I can reproduce the issue for further help.

ASPX:
<telerik:RadEditor ID="radeditorHidden" runat="server" Visible="false">
</telerik:RadEditor>
<telerik:RadTextBox ID="radtxtCheckText" runat="server" Text="This is an exmaple line">
</telerik:RadTextBox>

Thanks,
Princy.

Hi,

I'll include the aspx file for a simple test that demonstrates the problem. It's not hard to reproduce and it is unfortunate I have to prepare a sample for you.

As I mentioned, this is a critical issue, since every time the user saves their content, another BR tag is added.  We can't unconditionally remove the BR tag because we have no way of knowing whether the user added it or the Editor added it.

Please provide a solution to this problem.

Thanks,
Trevor.


ASPX:

<%@ Page Language="vb" AutoEventWireup="false" Codebehind="TelerikTest.aspx.vb" Inherits="IronPoint.TelerikTest" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<html>
<body>
<form runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<h2>BR tag added when editor is initially hidden - Firefox only - editor version 2014.1.403.45</h2>
<h2>click button then switch to HTML mode - you will see a BR tag at the bottom</h2>
<div id="divWrapper" style="display:none">
<telerik:RadEditor runat="server" ID="RadEditor1">
    <Content>
        <p>this is line one</p>
        <p>this is line two</p>
        <p>this is line three</p>
        <p>this is line four</p>
    </Content>
</telerik:RadEditor>
</div>
<input type="button" onclick="document.getElementById('divWrapper').style.display='';" value="Show Editor" />
</form>
</body>
</html>

Hello Trevor,

The mentioned behavior is encountered becuase of the initially hidden state and a logic in the RadEditor because of which the onParentNodeChanged() method is called automatically. 

This method has an already logged bug and I suggest following the public feedback portal item for a possible resolution.

Also, when it comes to programmatic showing and hiding of the Editor, it is recomended to use the repaint() method to fix layout issues. More about this is explained in this help article.
