Hello,
I have a problem where the characters like "VIAÇÃO COMETA" comes as junk in the text box. This does not happen IE 6. Where as this happend in IE 7. Let me explain the scenario properly.
1. I have a parent page where in I get this value and set to a text box. (This comes perfectly all right).
2. I have to open a popup page which is basically a search page and the text becomes search criteria. Hence I am passing this as querystring.
var customerName = document.getElementById("txtCustomerName").value;//Read this into variable
var url="SampleSiteSearch.aspx?SCREENTYPE=POPUP&CUSTOM ERNAME="+customerName;//Pass QueryString.
I have given Alert to check this and it comes fine.
3. In the popup I am reading this value as below.
txtCustomerName.Text = Server.UrlEncode(Request.QueryString["CUSTOMERNAME"].ToString());
Here the junk character comes. Hence the popup shows junk characters and my search does not work.
I have tried giving URLDecode/HTMLdecode but no result.Can any one help me in this.

I'm not sure I understand what you are attempting to accomplish.

If it is your intention to URL-encode the string, you should be doing that before passing it on the querystring. URL-encoding a string that is already in a URL doesn't really make sense.

Hello,
Yes this Decoding is not applicable. Also please note that I am using Javascript to Form the URL and then Use window.open method to open.

But when am trying to read the Querystring Value it returns me as Junk Characters. In some systems it is working in some systems it does not work. Not sure if IE / some setting of IE could be the reason.

Yes, obviously. That's because you are calling the Server.UrlEncode method, which replaces non-alphanumeric characters with URL-encoded characters.

The point that I was trying to make before is that it makes no sense to Url-encode a value you are getting off the querystring. In other words, why are you even calling Server.UrlEncode?

Hello,
Perhaps I didnt clarify you properly. Am not doing URLdecode. I am simply reading the query string. Request.QueryString["CUSTOMERNAME"].ToString()

I had tried URLDecode to check if this helps. Actually my code does not have this still it returns me junk characters.

Okay, you're not following me at all here.

From your original post, you said you were doing the following:

txtCustomerName.Text = Server.UrlEncode(Request.QueryString["CUSTOMERNAME"].ToString());

When you call Server.UrlEncode on a string such as "VIAÇÃO COMETA", you get the following:

VIA%ef%bf%bd%ef%bf%bdO+COMETA (in IE 8)

VIA%c3%87%c3%83O+COMETA (in FF3)

The ASCII characters are not altered. However, the non-ASCII characters (Ç and Ã) are altered. The [space] is also changed to a +.

What I am trying to tell you is that there is no need to call Server.UrlEncode here. It makes no sense, since you are reading the string OUT of the querystring. The Server.UrlEncode method is only meant to be used when you are putting the string INTO the querystring.

I don't know how to explain it any more plainly than this. Maybe someone else could jump in at this point and try to make it clearer.

Dear Lee,
There is still confusion in this. Perhaps this is with the code I have given in query( Original Query). As I had explained in the last reply I am actually not using URLDecode in the code. It's that I was trying putting the URLDecode and test and I pasted that code in the original query. Hence below is the correct code which is present in my solution and this below code itself returning the Junk Characters like "VIA??O COMETA"

txtCustomerName.Text =Request.QueryString["CUSTOMERNAME"].ToString();
