RadEditor with embedded video hangs IE6

[Phil]

Hi All,

I have an issue where if I use the MediaManager to link in a wmv file to the RadEditor it hangs IE6 on the following Reponse.Redirect.

On the Button_Click event I am calling a method to save to the database.

<asp:Button runat="server" ID="SubmitButton" Text="Submit For Approval" CausesValidation="true" OnClick="SubmitButton_Click" OnClientClick="javascript:window.scrollTo(0,0);" />

Which calls the method in the code behind.

    Protected Sub SubmitButton_Click(ByVal sender As Object, ByVal e As EventArgs) Handles SubmitButton.Click
        CreateNewArticle()
    End Sub
 
    Private Sub CreateNewArticle()
 
        Dim newArtID As Int32 = 0
        Dim body As String = String.Empty
        Dim art As Article = Nothing
        Dim artBody As ArticleDetail = Nothing
 
        Try
            'create the new article
            art = Article.CreateArticle(-1,
                                        articletitle.Text,
                                        articlesummary.Text,
                                        False,
                                        Date.Now,
                                        System.Web.HttpContext.Current.User.Identity.Name.Remove(0, InStr(System.Web.HttpContext.Current.User.Identity.Name, "\")).Replace(".", " ").ToUpper,
                                        GetVisibiliy)
            art.UpdatedDate = Date.Now
 
            If articlebody.Content.Contains("<img") Then
                art.ThumbnailImage = Mid(articlebody.Content, InStr(articlebody.Content, "src=") + 5, InStr(InStr(articlebody.Content, "src=") + 5, articlebody.Content, "/>") - (InStr(articlebody.Content, "src=") + 5)).Replace(Chr(34), "").TrimEnd
            Else
                art.ThumbnailImage = "~/Content/Images/JCBLogo.png"
            End If
 
            'create the article detail
            artBody = ArticleDetail.CreateArticleDetail(-1, -1, articlebody.Content.Replace("&nbsp;", " "))
 
            'save to the db
            Using insertContext As New JCB_IntranetEntities
                insertContext.AddToArticles(art)
                insertContext.AddToArticleDetails(artBody)
                insertContext.SaveChanges()
            End Using
 
            newArtID = art.ArticleID
 
        Catch ex As Exception
            ErrorLogging.AddNewErrorLogEvent(ex)
            Throw
        Finally
            If articlebody.Content IsNot Nothing Then
                articlebody.Content = Nothing
                articlebody.Dispose()
            End If
            If artBody IsNot Nothing Then artBody = Nothing
            If art IsNot Nothing Then art = Nothing
        End Try
 
        'If the save worked then redirect to the article
        If newArtID > 0 Then
            Response.Redirect(String.Format("~/Articles/Article.aspx?ArticleID={0}", newArtID))
        End If
 
    End Sub
 

The data saves correctly but hangs on the Response.Redirect at the bottom of the method. I have checked the Page Load in the called page and the code runs through as expected. I did check to see if it was a problem with the target page by changing the redirect to www.google.com and experienced the same behaviour.

This only seems to happen if I embed a video into the editor, if I use just text & images the save and redirect works without issue. I have also confirmed that it works in Firefox & IE7/8.

Any thoughts you have would be welcome.

Anyone have any ideas?

Hi Phil,

Unfortunately, I am not aware of such a problem and you are the first to report it. It is definitely an IE6 browser bug, because it does not exist in the newer versions.

The problem is most likely related to the submitted content. Could you please perform a test by replacing RadEditor with a normal Asp:TextBox control and submit the same content and redirect the page to the new page?

If you are unable to reproduce the problem with the textbox, please isolate it in a sample working project and send it for examination by opening a support ticket. I will debug it and find what part of the content is hanging the browser.

Best regards,
