I want to use FCKeditorV2 (Figure 2) http://www.mediafire.com/view/oahtm7k3883elow/website2010_10a.jpg/file
instead of FreeTextBox (Figure 1) http://www.mediafire.com/view/pdmvi0aezyqpil5/website2010_10b.jpg/file
 
The code I have edited
[CODE]
In file ArticleAddEdit.aspx 
line 5: 
original
<%@ Register TagPrefix="FTB" Namespace="FreeTextBoxControls" Assembly="FreeTextBox" %>
 
edit
<%@ Register TagPrefix="FCKeditorV2" Namespace="FredCK.FCKeditorV2" Assembly="FredCK.FCKeditorV2" %> 
 
 
 line 79:
 original: 
TabIndex="3"
toolbarlayout="FontFacesMenu,FontSizesMenu,FontForeColorsMenu,FontForeColorPicker,FontBackColorsMenu,FontBackColorPicker|Bold,Italic,Underline,Strikethrough,RemoveFormat|JustifyLeft,JustifyRight,JustifyCenter,JustifyFull;BulletedList,NumberedList,Indent,Outdent;CreateLink,Unlink|InsertTable,EditTable,InsertImageFromGallery"
runat="Server"
Width="585px" Height="200px"
/>
 
edit:
 
 
[/CODE] 
But when I change the code the following error message: http://www.mediafire.com/view/zpze8g7k7o3wm4a/website2010_10c.jpg/file
 
Line 40: txtTitle.Text = obj.Title;
Line 41: txtExcerpt.Text = obj.Excerpt;
Line 42: txtBody.Text = obj.Body;
Line 43: if (obj.Priority == 1)
Line 44: chkPriority.Checked = true;
 
For the original code
