Hello,

i try to use the RTE inside an updatepanel, but i always get the error:

updatepanel could not be set on property contenttemplate

The RTE runs fine in Browser, but the updatepanel is not working.

Any help would be very nice!

Greetings Matt 

Dear customer,

For html post on aspx page,

you should add the following code

1.  add  ValidateRequest="false" to <%@ Page %>, like <%@ Page Title="Contact" Language="C#" MasterPageFile="~/Site.Master" ValidateRequest="false" AutoEventWireup="true" %>

2. if you use asp.net 4.0,  need to add the following snippets to system.web section of web.config

<httpRuntime requestValidationMode="2.0" /> 

Regards,

Jeff 

Hello Jeff,

thank you for  fast response, but your suggestions did not help. I tested the cuteditor before and that was working fine.

Page EnableEventValidation="false" ValidateRequest="false" Title="" Language="vb" AutoEventWireup="false" MasterPageFile="~/content.Master" CodeBehind="content_add.aspx.vb" Inherits="zutzu.content_add" 

As soon i delete the editor:

<RTE:Editor id="cedi" Text="" runat="server" EditorBodyClass="../../css/site.css" Width="100%" Height="500" AutoFocus="True" /> 

it works again!

hi comb,

Can you try the example page below? Does it get the same error?

 Hi Kenneth,

no that works :-/

So it is something else wrong... I try to solve it myself.

Thanks alot!

Ok, that was easy :-)

The Problem was the Text = "". After removing it, the UpdatePanel throws no more Errors.

Thanks alot to all that tried to help!
