[Solved] Loading Content From An HTML file

[John Reid]

Hi -

I am loading the editor content from an HTML file with the following code:

Private Sub LoadEditor(ByVal File As String)

 

 

Dim sr As System.IO.StreamReader

 

 

Dim fi As New System.IO.FileInfo(File)

 

 

Dim strContents As String = ""

 

 

If System.IO.File.Exists(File) Then

 

sr = System.IO.File.OpenText(File)

strContents += sr.ReadToEnd()

Editor.Content = strContents

sr.Close()

 

Else

 

 

End If

 

 

End Sub

I seem to get a few errors that I can't figure out:

1. In the HTML there is a link with a query string. e.g. 
<A href="http://www.abc.com/Default.aspx?id=118&cost=WR1841" target=_blank>
The Editor converts it to:
<A href="http://www.abc.com/Default.aspx?id=118&amp;cost=WR1841" target=_blank>

2. There are special characters like ®
The editor just displays a �

Any help will be appreciated

Hi John,

Straight to the points:

1) It is the browser's editing engine itself that changes the ampersand to &amp; in this scenario. What you can do is to use a custom content filter that will change it back.
Please check the following KB that shows how to create and use such filter:
http://www.telerik.com/support/kb/aspnet-ajax/editor/converting-unicode-symbols-to-numeric-html-entities-using-a-content-filter.aspx

For example you can use the following regex for the replacement (code is based on the KB)
newContent = content.replace(/&amp;/gi, "&;");    

2) This is an encoding problem due to that the file content is not saved with Unicode (UTF-8) formatting.
You should make sure that the file is saved with Encoding.UTF8, e.g.

Protected Sub Button1_Click1(ByVal sender As Object, ByVal e As EventArgs)
            Using externalFile As New StreamWriter(Me.MapPath(path), False, Encoding.UTF8)
                externalFile.Write(RadEditor1.Content)
            End Using
End Sub
