Web Forms :: .Net 4.0 Attributes.Add Encoding Bug?
May 4, 2010
.Net 4.0 is encoding values when using Attributes.Add. In previous versions it didn't. With the new behaviour it is no longer possible to write attributes containing single quotes.Here's an example.
I have written a web mailer that can send and receive emails and display them on a webpage.I have a problem displaying special characters though. Like Russian, and Greek and chinese.I am using openpop.net and I can get the encoding of the incoming email as one of my variables.Thing is, how do I display it? Do I set the content encoding of the whole page to what that specific email encoding is?I've got it UTF-8 at the moment and I get garbage.
Im pulling out a text field from the database which has and 's in it for line breaks. Which I have left there for pupose of being able to edit the fields later on.
So when i try to display the text I need to replace them which I have done with:
[Code]....
Simple enough. Only when I run the page the source code I get for it is:
<br />
So it seems its not encoding the < as a encode but into the form <
Does anyone know how to stop this happen. Or a method around it?
I am accessing this xml file by using LINQ to XML in asp.net by using C#. I am able to access all the attributes of an XML node by explicitly specifying the name of the attribute. I want to write query on this xml file which reads all the attribute values of the xml node (In our example the node is SERVER) dynamically means I want to write the query which can read the read the value of the attribute Name & ID from first node, only name from second row, Name, ID & Parent from the third row , Name & ID from the fourth row, Name, Parent & Value from the fifth row & only Name from the sixth row without modifying the existing code every time. Once I add one of the attribute ( for example if I add the attribute ID in the sixth row ) in the above xml file then I dont need to modify my LINQ to XML query. My query should dynamically fetch the total number of attributes & display their values. Is their any way to do this ?
Can someone lead me to understanding when to set the encoding for the email step when sending new member emails. For instance what is the default or how can I tell what it is or if I want to set it in the SendMail event in code. See the thing I am wondering is when is it applied? If I set the MailDefinition-From in the html part then in code using the SendMail event set the encoding using
e.Message.From = new MailAddress("foo@bar.com","foo",System.Text.Encoding.UTF8);
then I assume that it must actually get applied when the email is sent. Is that correct?
I have a browser-like software application that logs in to my asp.net site through the login control. Depending on the user info used, the application gets redirected to a text file in the server. The content of the file is then displayed in the application.
The files are created using vb.net streamwriter createtext.
I can get the content of the file correctly the first time the application logs in to the website, but the the 2nd and succeeding attemps results in garbage data (different encoding maybe?). I didn't get this problem when I was hositng the asp.net site locally using (IIS 5.1) - the site is currently hosted using II 6 remotely. what could be wrong? Could it be because I don't log-out of the site?
I have spent quite a bit of time researching this here on Asp.Net's Forums, but also on the web in general, and I am still drawing a blank.
The problem: I am trying pass a values such as ... "Jacob's Carpentry" as a query string to another page. However, the other pages keeps seeing "Jacob\s Carpentry".
What I have tried: I have tried using both the Server.UrlEncode and HttpUtility.UrlEncode, and neither have worked. I have also tried using them twice as was suggested in this article, but still with no luck. Finally, I went so far as to try and encode the string, but then do a String.Replace on the " ' " apostrophe and substitute with a "%27". This also did not work, as it appeared that the String.Replace wiped out the encoding.
So I am stuck/lost. It appears the standard PHP functions easily encode the apostrophe, but for some reason the .Net function isn't working.
Here is the code I am using ...
[Code]....
I notice, however, then if I put a breakpoint where the PostBackUrl is set, the encoded string is still only showing "Jacob's+Carpentry", no %27.
For some reason the encoding on my website has gone wrong. Turkish characters that were working before are now coming out in '?'. I have not touched anything. Our regular developer is away so I'm not sure if he touched anything. The text has been working on this page till recently and on the previous years page. That has now been affected to. I have set the following statement in the <head> section:
< meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> Unicode UTF-8 has worked in the past.
When I view the encoding in Internet Explorer 8 tools menu it is saying 'Western European(ISO)'. In my test environment, encoding is showing up as Unicode UTF-8 and hence the code is correct. So my question is, why is the encoding change to Western European (ISO) and how can I change?
I would like to make sure that everything that goes into my database is safe, i.e. protection from sql injection.
What I want to do is type something in a textbox, "<b>hello</b>" for example, it be encoded before it's put in the database, but when I retrieve it, I want it to display "hello" in bold.
I've tried the obvious of server.encode on input and server.decode on the output (to a label and a literal control), but couldn't get it to display the text in bold without having unencoded text in the database.
I am starting work on an already fully developed site. This site has no input encoding or output encoding. If some one ebters <input type="text"> in an insert form it is displayed as a real tex box when viewing that form details.
So how can i apply encoding at input or output to the WHOLE SITE?
turning on validate request is not an option as the cms wud need it off.
also this is .net 3.5 so no question od using <%: tags.
In my application i have gridview that I export it to excel. When exporting I have the option to select if show the data with images or with no images. The application run well, but when i try export Hebrew data I got gibberish letters. The second thing is that if I select the option "with no images"
Sometimes the Hebrew seems good, and sometime not. Of course I add the Response.ContentEncoding. I thing maybe I should encoding one of this rows

But don't know how. Here is my application printscreen. and this is my code
Has anyone else encountered a problem with Framework 4 automatically html encoding multilingual characters?I am uploading a spreadsheet with both English and Spanish characters. When I preview it on the page everything looks great however as soon as I attempt to pass it to the stored procedure the non-roman characters are being automatically converted to, what looks like, html encoding.This code worked flawlessly in 3.5 and has not been touched. The only change is that I switched to framework 4 however I haven't seen anything indicating that this would be a problem for me.
wanting to add the freetextbox from freetextbox.com to it.But before i add that I want to get html encoding working with out having to put the pagevalidation to false.This is what I've been reading and trying to work. I have the encoding from the database to teh site working fine. Its the encoding to the database that is being a pain in my back.http://dotnetslackers.com/articles/aspn /Encode_and_Display_HTML_Securely_in_ASP_NET_2_0.aspxI've added the validaterequest to false and encoding my text by the following.

I have discovered that the NavigateUrl is encoding the URL when it render it. It is a bit of a problem for me in Denmark because we have domianname with special charters. ex. [URL] the hyperlink control render it like [URL]
In a website I'm working on, there is a link to ~/Products/1/2%20Inch%20Tube.aspx (1/2 Inch Tube.aspx). As I'm using a fake path the name of the URL is not a problem appart from the fact that there is a slash in the name. The URL safe code for it is %2F, and I use a replace to check for this in my SQL query (REPLACE(ProductName, '/','%2F')) AS Link, and before that in the eval statement (NavigateURL='<%# "~/Products/" & Eval("Link").ToString.Replace('/','%2F') %>'). Sadly when databinding this using an eval to a Hyperlink, the %2F changes back to a / (Slash)
Is there a work around for this or should I just not allow for slashes when saving products.
My question is whether it is possible or not to extract the "is_tube_mailer" field from the Treeview's Treenode. I attempted to cast the node.DataItem to an Xmlnode, however that only seemed to work in the TreeNodeDataBound event. I need to do this within a Button.Click event routine.
I have a dropdown list where I need more than just a bound value and a display value. I am using this in the page load event to add a custom attribute:

I'm actually looping through a sqldatareader for a list of employees, but for simplicity just consider the single option added above. When I go to check the attribute EmpNum for the selected option, I am getting "null":
[Code]....
Now the really weird part...If I add an option in the HTML source identical to the one that gets added in the codebehind, the javascript function works for that row, but not the row added from codebehind. Here is the rendered HTML for the SELECT:
[Code]....
If I select the 1st record (added from HTML source at design time) the alert says "12345". If I select the 2nd record, the alert says "null". I CAN get the value ("999-99-9999") and the displayed text ("John Doe") for either record, just not the EmpNum attribute, even though the HTML is exactly the same. I am completely stumped on this one.
I just want to add and attribute called "pubID" to an image button with the value I give it and then call that value on the image button click event. This image button was created dynamically as well. At the moment this code is not working. When debugging it looks like Pubid is getting assigned a value but on the click event, the attribute isn't being retrieved correctly.
tried many approaches like below to determine which web page form buttons are checked and then get all the attributes for those checked buttons, getting nowhere fast, note on the sample code below, a button was checked but nothing was found with this code, there's got to be a way to this, yes?
Dim MyControl As Control Dim MyRadioButton As RadioButton For Each MyControl In Page.Controls If MyControl.GetType().FullName.ToString = "System.Web.UI.WebControls.radio" Then MyRadioButton = MyControl If MyRadioButton.Checked = True Then foo = MyRadioButton.Attributes("name") End If End If Next
this is what the radio buttons are like they have unique id's and values, its the name attribute that groups them
I have a web user control (wcCmdBtn.ascx) which has an asp.net button and i need to add an additional attribute from the form page that the user control is linked on. My button name is btnExport and my language is vb.
