Hi!

I have a RadEditor in an InsertTemplate in a RadGrid. The problem is: If I click a save-button i have in the same template and try to insert the text from the editor to the database, then the grid performs a callback, and all text is removed from the editor.

The same happens if I try to set a text in the editor when I click the button in the grid which opens the InsertTemplate, and also if I try to save the text from the editor directly to a grid when I save.

It seems that the editor clears all text and settings at each callback. Could it be that it is cleared when I declare it through the following in the ItemCommand of the grid:
RadEditor editTTNewThread = (RadEditor)editFormItem.FindControl("editTTNewThread");

I had the same problems with edit and callback in earlier versions. I tried the same in IE8, and there I manage to set the text programmatically, just after the declaration above, but the same happens when I click the save-button. The editor is cleared.

Edit: In the previous version of the RadControls, I had to use postback instead of callback for it to work, but I really hope that can be avoided.

Another edit: I have now tried the editor in other pages as well, and it seems that every time I use callback on an editor, all the content is cleared.

Any ways to fix this issue?

Cheers,
Erlend Haukland

Hi!

Below is the code I am using just to test this

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="EditorTest.aspx.cs" Inherits="EditorTest" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<!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>Untitled Page</title>
</head>
<body>
    <form id="form1" runat="server">
    <asp:ScriptManager ID="smMaster" runat="server" />
    <div>
        <telerik:RadAjaxPanel runat="server" ID="test">
            <telerik:RadEditor runat="server" ID="editTTNewTT" ToolsFile="Skins/Scorpion/Editor/ToolsFile.xml"
                Skin="Office2007" Width="500" Height="350" EditModes="Design">
            </telerik:RadEditor>
            <br />
            <br />
            <asp:ImageButton runat="server" ID="btnTest" ImageUrl="Img/Buttons/save.png" />
        </telerik:RadAjaxPanel>
    </div>
    </form>
</body>
</html>

I have stripped down my page to a minimum of controls, just the editor and a button. The funny thing is:

If I use an ImageButton to save, the text in the editor is cleared. If I use a regular asp:Button, however, it works just fine. The button does nothing at this point. It just performs a callback. Could you please look into this, and see if you can find any issues with this?

Cheers,

Hi Erlend,

I am aware that this problem appears in Firefox. Does the problem appear in IE8 beta too?

The solution for the problem is described in the following article: RadEditor Content Not Saved After Ajax Update in Firefox.

When the editor is placed in RadGrid, you can use the following code to fix the problem.

        protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
        {
            GridEditFormItem item = e.Item as GridEditFormItem; //get a reference to the Edit Image button
            if (null != item && item.IsInEditMode)
            {
                ImageButton but = item.FindControl("UpdateButton") as ImageButton;
                but.Attributes.Add("onclick", @"javascript:__doPostBack(this.id,'');");
            }
        }

Please, test the code in both IE and Firefox and let me know if you still experience any problems.
