Hi,

I am using the container in my form. Inside that I am using the HTMLEDITOREXTENDER for the text box when I run the application in IE7 the form is not loading. When I run the application Firefox and chrome the Toolbar is displaying bottom of the textbox. In IE7 I am getting the error as :

"Object doesn't support the property or method".

Here is the code:

<td align="left" colspan="3">

 <asp:TextBox ID="editorConsultantDetails" runat="server" TextMode="MultiLine" 
                                                                    Width="600px">                                                            <asp:HtmlEditorExtender ID="HtmlEditorExtender1" runat="server" Enabled="True" 
TargetControlID="editorConsultantDetails">
<toolbar>                                                                        <asp:Bold />                                                                        <asp:Italic />                                                                        <asp:Underline />                                                                        <asp:InsertOrderedList />                                                                        <asp:InsertUnorderedList />                                                                        <asp:Indent />                                                                        <asp:Outdent />                                                                        <asp:FontNameSelector />                                                                        <asp:FontSizeSelector />                                                                    </toolbar>
