I have a field with product name
abc® product1
If I get the data from the database and databind it to the dropdownlist. It becomes
<option value="2">abc ® product1</option>
I don't want ASP.net to escape the ® to %amp;reg.
I need to be able to navigate through the file system from an asp.net page and gather metadata on files, directories ... The simple code I've put together makes a list of directories/files in a given location and has everything displayed as a link button. My problem is with link buttons under which I have paths that include ampersands and blanks. Here's a sample of code:
[Code]....
The Response.Redirect("aPage.aspx?d="+ e.CommandArgument.ToString()); line has the problem ... the e.CommandArgument.ToString() shows a truncated path that stops just before the first ampersand detected. I tried escaping the ampersand with a backslash but it did not work ... somehow I guess it's not exactly the character that's causing the problem ..
What is the escape sequence for &-sign in string literals in web.config?
View 2 RepliesI am trying to insert dynamic data into a onclick property for a control the code looks like this
onclick="openRadWindow('<%#Eval("ID";) %>','<%#Eval("ParentObjectID") %>');"
I cant get it to fire and the trouble seems to be the double quotes, what is the correct method on escaping the quotes so that this fires.
In my program, I want to make database connectivity, but when i write a connection string, complier says that it is unrecognized escape sequence(which is bolded in the following string), the string is :
Data Source=HIMANSHUSQLEXPRESS;Initial Catalog=Himanshu;Integrated Security=True
EDIT1:
btnDelete.Attributes.Add("onclick", String.Format(@"return DeleteRow('{0}',{1},{2},{3});", e.Row.ClientID, e.Row.RowIndex, DataBinder.Eval(e.Row.DataItem, "Id"), "'" + DataBinder.Eval(e.Row.DataItem, "Name") + "'"));
edit:
i get this error:

I have such code:
<%# (int)Eval("Favorites") > 0 ? "<a href="history.aspx?visitorid=<%# Eval("VisitorID") %">Favorites</a> / " : ""%>
where I show a link if value>0 .. However it gives me a bad url(history.aspx?visitorid=%3C%#%20Eval) when I put visitorID=<%#...%>inside another Eval<%#..%>
Are the any functions in C# that handle escape/unescape like JavaScript?
I have a JSON string like this:
{"Feeds":[{"Url":"www.test.com","FeedType":"Twitter"},{"Url":"www.test2.com","FeedType":"Youtube"}]}
Which looks like this after escape()
%7B%22Feeds%22%3A%5B%7B%22Url%22%3A%22www.test.com%22%2C%22FeedType%22%3A%22Twitter%22%7D%2C%7B%22Url%22%3A%22www.test2.com%22%2C%22FeedType%22%3A%22Youtube%22%7D%5D%7D
In my C# code I would like to unescape this string so that it looks exactly the same as it did before the escape()
buildLetter.Append("</head>").AppendLine();
buildLetter.Append("").AppendLine();
buildLetter.Append("<style type="text/css">").AppendLine();
Assume the above contents resides in a file. I want to write a snippet that removes any line which has empty string "" and put escape character before the middle quotations. The final output would be:
buildLetter.Append("</head>").AppendLine();
buildLetter.Append("<style type="text/css">").AppendLine();
The outer " .... " is not considered special chars. The special chars may be single quotation or double quotation. I could run it via find and replace feature of Visual Studio. However, in my case i want it to be written in c# or VB.NET
<asp:Button ID="myButton" runat="server"
OnClientClick='confirm("How do you escape this apos'trophe?")' />
what is an alternative for javascript escape function in c# for e.g suppose a string:"Hi Foster's i'm missing /you" will give "Hi%20Foster%27s%20i%27m%20missing%20/you" if we use javascript escape function, but what is the alternative for c#. i have searched for it but no use.
View 4 RepliesI find myself doing a ton of jquery these days so I started to abstract out some of the common things I do into snippets. I look forward to sharing these with the community, but i'm running into an issue right now. The literals in snippets are defined by adding dollar signs ($) around the name of the literal to delimite where the value you would like to provide will go. This is difficult because jQuery uses the dollar sign notation in order to use a lot of it's functionality. Does anyone know the escape sequence for snippets so I am able to use the dollar sign, and have my snippets still function?
View 7 RepliesI'm doing some databinding inside a ListView ItemTemplate, but I suspect this is a problem for any databinding/template situation. I want to write something like:

But I get a YSOD with an error message that the server tag is not well formed. How do I persist non-visible data inside my ListViewItem?
I have a web application.
I user Forms authentication and set Login.aspx as the Login url.
So when I try to enter any other page in my address bar Iam redirected to Login page as per its setting.
But now I need to give a link called Register in Login.aspx page.
Clicking on Register link should take me to Register.aspx page.
But as per authentication settings Iam redirected to Login page.
So is there a way to omit or escape the register.aspx page from this authentication setting.
I hope someone has a good answer to this stupid question I have. I'm trying to use impersonation in my asp.net 3.5 application within the web.config file to connect to my sql server 2008 database so I use:
When I run my app, I get this:
Configuration Error
Description: An error occurred during the processing of a configuration file required to service this request. review the specific error details below and modify your configuration file appropriately.
Parser Error Message: Could not create Windows user token from the credentials specified in the config file. Error from the operating system 'Logon failure: unknown user name or bad password.
Source Error:
impersonate="true" userName="testUser" password="test(ampersand sign, this forum actually does render it properly)amp;test" />
So basically it posts the password with the actual escape for ampersand rather than the actual ampersand. This leads me to believe it's processing it as a literal but validating it as xml, unfortunately I can't just use "test&test" in the web.config file because visual studio just won't compile it since it's marked as an error.
i have an asp.net controller that output Json as the results a section of it is here
returnString += string.Format(@"{{""filename"":""{0}"",""line"":[", file.Filename);
what i get returned is this:
"{"DPI":"66.8213457076566","width":"563.341067","editable":"True","pricecat":"6","numpages":"2","height":"400","page":[{"filename":"999_9_1.jpg","line":[]},{"filename":"999_9_2.jpg","line":[]}]]"
i have tried to return with the following methods:
return Json(returnString);
return Json(returnString.Replace("\","");
return Json will serialize my string to a jSon string, this i know but it likes to escape for some reason, how can i get rid of it? for info this is how i call it with jQuery:
$.ajax({
url:"/Products/LoadArtworkToJSon",
type:"POST",[code]...
I'm where am i going wrong with my hyperlink?

i get a compilation error, Unrecognized escape sequence.
I'm trying to connect to my sql server 2008 database and I'm using impersonation within my asp.net 3.5 application
<identity impersonate="true" userName="testUserName" password="test&test" />
Naturally the compiler won't compile until I use the escape character:
<identity impersonate="true" userName="testUserName" password="test&test" />
So it compiles, unfortunately when I run my app, it get this:
Parser Error Message: Could not create Windows user token from the credentials specified in the config file. Error from the operating system 'Logon failure: unknown user name or bad password.
Source Error:
<identity impersonate="true" userName="testUserName" password="test&test" />
need to show up 4 columns whenever user press keys in textbox, i need to collect these keys and send it to the service which will give us result as xml. then i convert xml to dataset and binded with datagird. for this i used jquery. after the result displayed ( i mean the result in datagrid which is placed in div), then i need to hide the div when the user clicks outside of the div or press escape key...
function showList() {
if(document.getElementById("txt1").value.length > 3) {
$("#divList").hide("slow");
$("#divLoading").show();

I've got a gridview with a hidden field, i'm trying to set a value as follows:
value='<%# DataBinder.Eval(Container.DataItem, "Name")%>'
which works in most cases except when the name has an apostrophe like O'Neil. I need to escape the ' if possible.
so i tried: value='<%# DataBinder.Eval(Container.DataItem, "Name").ToString().Replace("'", " /' ")%>' and
value='<%# DataBinder.Eval(Container.DataItem, "Name").ToString().Replace("'", " //' ")%>'
which doesn't work because of the final apostrophe in the notation i.e. %>' It truncates after the word e.g O'Neil Someone becomes O' which is incorrect.
This works like a charm: value='<%# DataBinder.Eval(Container.DataItem, "Name").ToString().Replace("'", "'")%>' which isn't good practice as I don't want to hardcode '
I have data that I am trying to read in from a .csv file. Some of my fields however have their own commas. For instance my file may look like:
Name, City, Country
And my data may have:
Walmart, New York, USA
"My store, and more", New York, USA
If you look at the second row of my data you will notice the first field has a comma in it: "My Store, and more".
It is surrounded by double quotes to distinguish that the field includes the comma, but when I read it into a table in MSSQL it splits that field into two. How do I tell MSSQL to leave everything in the double quotes as one field?
I'm trying to output some Twitter handles in ASP.NET MVC3 in conjunction with the Twitter @Anywhere API, and I haven't been able to figure out how to actually escape the "@" symbol in a Razor view. Does anyone know what the syntax is for escaping the "@" character in Razor? I've tried using <text></text> and that results in a JIT error.

I know that most people store the Database connection string inside the web.config file.
But my question is if we move the web.config file from dev to prod then we have to change the connection everytime.
how can we have a connection string that we do not have to change when we move our code from dev to prod.
I have a database (SQLExpress) to populate my web page with some products.
Some times, I want to perform an if else function to the result (which seems to be very difficult in asp.net for some reason - compared to asp.classic).
The code works fine
string PN = (Convert.ToString(ds.Tables["B2B"].Rows[0]["PartNumber"]));
Is there a better way to do this? Or is this the correct way?
Second question is:
ds.Tables["B2B"].Rows.Count;
also works. correct my terminology but the ds parameters(?) Tables, Rows and Count all belong to ds. How does any one know this? How would I know what else I can use with ds? I have viewed the microsoft website to try to work out what I can and can't apply and have gotten no where! Is there a site which says if you use XX, then you can use the following parameters.
