AntiXss.UrlEncode Vs. AntiXss.HtmlAttributeEncode Usage In Link (a Href)?
Aug 26, 2010
According to old AntiXss article on MSDN AntiXss.UrlEncode is used to encode link href (Untrusted-input in the following example):[URL]My understanding was, that UrlEncode should be used only when setting something to URL, like when setting document.location with JS. So why don't I use HtmlAttributeEncode in the previous example to encode [Untrusted-input]? On the other hand is there a security flaw if I use UrlEncode to encode HTML attributes like in the above sample?

When you can simply encode the data using HttpUtility.HtmlEncode, why should we use AntiXss.HtmlEncode? Why is white list approach better than black listing?Also, in the Anti XSS library, where do I specify the whitelist?

I have the following HTML with a databinding expression as shown below:
[Code]....
The 'title' tag's expression gets evaluated fine.
But not the one in 'href' attrib of the 'link' tag. The HTML source generated shows the literal text "..this.BaseURL.../..."
Any idea what could be happening?

My client wants to pass values through the query string, but they don't want the query string to be displayed in the browser's address bar. The values being passed are for tracking purposes. I know that postback doesn't happen after you click on href link.Is there any way I can get the value out of the query string without displaying it in the browser's address bar? I think this may be impossible, but I may be wrong; I'm hoping to see if anyone has any answers.

I have href links inside a datalist and want to make sure that the top link is clicked by default. The reason for this is that the href inside the datalist will show a different friendly url each time one is selected and also fill a seperate detailsview with data based on values from the query string. I want the user to see the friendly url and first lot of data once he navigates to a page is this possible ?.

In ASP:
Server.URLEncode("+&(). -*<>/|")
' returns %2B%26%28%29%2E+%2D%2A%3C%3E%2F%5C%7C
In ASP.NET
Uri.EscapeDataString("+&(). -*<>/|")
// returns %2B%26().%20-*%3C%3E%2F%5C%7C
HttpUtility.UrlEncode("+&(). -*<>/|")
// returns %2b%26().+-*%3c%3e%2f%5c%7c
Is there any elegant way how to mimic old ASP behavior in ASP.NET?

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.

So I have a Hyperlink called lnkTwitter:And I'm trying to set the url in the code behind:lnkTwitter.NavigateUrl = string.Format("http://www.twitter.com/home?status={0}", Server.UrlEncode("I'm Steven"));When I do that and hover over the link, the url displays correctly in the status bar as "http://www.twitter.com/home?status=I'm+Steven", but the actual url, if I click on the link or look at the link's properties, is "http://www.twitter.com/home?status=I%27m+Steven".For some reason, this only happens in Firefox; in IE, I am taken to the correct url.

What is the best way to encode the url in Hyperlink without writing code behind. I have many uses and I would like to do it in the Hyperlink statemeent if possible. Some thing such as the following would be great:
(This does not work)
<asp:HyperLink
ID="HyperLink1"
NavigateUrl=
"<%=UrlEncode(~/All_Videos.aspx?tag=full length movie&title=The Movie)%>"runat="server">Movies</asp:HyperLink>

I have two page
1-index.aspx
protected void ImageButton3_Click(object sender, ImageClickEventArgs e) {
string data = Server.UrlEncode(txtNumeric.Text);
SqlCommand _cmd = new SqlCommand("traidname", _cn);
_cmd.CommandType = CommandType.StoredProcedure;
_cmd.Parameters.Add("@BehCode", data);
[Code] ....
Here I use textbox .text for server.urlEncode according to this code it go to tName + "?BehCode=" thatÂ
SP
ALTER procedure [dbo].[traidname]
@Behcode nvarchar(30)
as
begin
select T_name
from House_Info
where Behcode=@Behcode
end
And this is code in my destination(depending to tname column in house_info tabel) page
I use below code to bind data from database in destination pages
 string data = Server.UrlDecode(Request.QueryString["BehCode"]); _cmd.Parameters.AddWithValue("@behcode", data);
Now in index.aspx page i have linkbutton that i want when users click on it, it do something like
ImageButton3_Click  eventÂ
This is my datalist code that linkbutton is in this datalist
 <asp:DataList ID="DDLstore" runat="server" RepeatColumns="3" RepeatDirection="Horizontal" "> <ItemTemplate> <table class="DDL2h"> <tr> <td style="height: 35px"> <asp:Label ID="Label3" runat="server" Text='<%# Eval("Name") %>' CssClass="TDnameH"></asp:Label> </td> <tr> <td> <asp:LinkButton ID="LinkButton2" runat="server" CssClass="LBP2" onclick="LinkButton2_Click">see all product</asp:LinkButton> </td> </tr> </table> </ItemTemplate> </asp:DataList>
Now how I can write code for linkbutton event that do same thing like ImageButton3_Click event?
and notice that both linkbutton and imagebutton are in index.aspx page ...
