RadEditor inside UpdatePanel

[Renato]

Hi, actually I have the code below working fine, but when I put the RadEditor inside an UpdatePanel to make it asynchronous, the code-behind dont get the RadEditor content value. Is it possible to pass the value inside an UpdatePanel, how? thanks

<telerik:RadEditor ID="reComment" runat="server" EditModes="Design" ToolbarMode="ShowOnFocus" ToolsWidth="170px" Width="412px" Height="72px">

                    <Tools>
                        <telerik:EditorToolGroup>
                            <telerik:EditorTool Name="Bold" />
                            <telerik:EditorTool Name="Italic" />
                            <telerik:EditorTool Name="StrikeThrough" />
                            <telerik:EditorTool Name="Underline" />
                            <telerik:EditorTool Name="InsertUnorderedList" />
                            <telerik:EditorTool Name="InsertOrderedList" />
                        </telerik:EditorToolGroup>
                    </Tools>
                </telerik:RadEditor>
                <input id="inpHide" name="inpHide" type="hidden" runat="server" />
                <span class="exp-bout-comm">
                    <asp:Button ID="btSubmit" runat="server" Text="Valider" OnClick="btSubmit_Click" /></span>

if (!IsPostBack)
{
    base.OnLoad(e);
    GetExistingComments();

    if (ScriptManager.GetCurrent(Page) == null)
    {
        ScriptManager sMgr = new ScriptManager();
        Page.Form.Controls.AddAt(0, sMgr);
    }

    btSubmit.Click += new EventHandler(btSubmit_Click);

    if (reComment == null)
    {
        reComment = this.FindControl("reComment") as RadEditor;
    }

    string content = reComment.Content;
}

Hello,

The reported problem is described in the following article: RadEditor Content Not Saved After Ajax Update in IE9, Firefox, Google Chrome and Safari. You can fix it using this code:

<asp:Button UseSubmitBehavior="false" ID="btSubmit" runat="server" Text="Valider" OnClick="btSubmit_Click" />

Hi Renato,

I reproduced the problem using the RadEditor control in an Update panel in SharePoint 2013 and I can confirm that this is a bug and I logged it in our database for fixing.

As a token of gratitude I am updating your Telerik points.

Also you could follow this feedback portal item, where you could track the bug status, vote or comment

Was this ever fixed in a particular version? I have this same issue running a SharePoint 2010 web part in SharePoint 2016 (obviously runs in 2010 mode). Same code is fine in 2010 native.

Hello Des,

The FIX RadEditor in an UpdatePanel is not ajaxified and loses its content after a post back in IE10/IE11, the same result occurs in a custom WebPart for SharePoint 2013 scenario item has been closed due to lack of popularity - it doesn't have a single vote in it.

What you can try is to:
- get the content prior the postback/callbeck on the client editor.get_html(true) and set it with editor.set_html(editor.get_html(true)); in the OnClientSubmit event.
- not ajaxify RadEditor, i.e. exclude it from RadAjaxPanel, RadAjaxManager or the UpdatePanel.
- vote for the bug report in the feedback portal. The more users request it, the bigger the chance to get fixed is.

Best regards,

Thanks Rumen.  I have updated the portal and I didn't know about the new PostBackControls tag in RadAjaxPanel which I'm hoping will fix the problem.
