Web Forms :: Inline Expression Or Binding Expression In The Server Head Section?
Aug 25, 2010
I write inline expression and binding expression in the server head section:
[Code]....
[Code]....
But both kinds of expression aren't parsed or executed except the ResovleUrl menthod. The html renders like this:
<head><link rel="stylesheet" type="text/css" href="<%= Request.ApplicationPath %>themes/style1.css" /><link rel="stylesheet" type="text/css" href="<%# Request.ApplicationPath %>themes/style2.css" />
<link rel="stylesheet" type="text/css" href="/themes/style3.css" />
<script type="text/javascript" src="/js/jwork.js"></script>
</head>
As I know, the inline expression in the attributes of server control can't be parsed but the binding expression should if we invoke the DataBind method. But the above case breaks the rule.

I'm trying to use the validator to work on a email form to ensure that they enter a valid from email address. That part works. I also want to add to the expression the text that I pre-populate in the txtbox ("Enter your email address") so on postback, after sending the message, I can clear the fields and repopulate that box.
How do I add that wording to the current expression: w+([-+.']w+)*@w+([-.]w+)*.w+([-.]w+)*

I am using Regular Expression validator for a text box. The below is working fine.It is not performing validation when I enter values like 0000..001.How can I modify validation expression? But it would allow values like 100,...5000 i.e zeros after a number.
<asp:RegularExpressionValidator ID="reg2" runat="server" ControlToValidate="rng2"
ValidationExpression="^[0-9]+" ErrorMessage="*Please Enter a Valid Number for Second Range."
ForeColor="Red" Font-Bold="True"></asp:RegularExpressionValidator>

I'm just testing a simple databind expression with:
<div>
Now: <%# DateTime.Now.ToString()%>
</div>
According to MSDN:
[URL]
literal text <%# data-binding expression %>
should work.
When I compile, it's OK but I got a blank instead of Now DateTime.

Code Behind has function which looks like

The whole reason for passing the reference is to save round trip to database and not to use SESSION

i have to check if an input string is valid based on the given regular expression.. this is the regular expression.
(a(bb+aaa+((ab)*bb+(aba)*aa)(a+b)*) + (b(aa+bbb+((ba)*aa+(bab)*bb)(a+b)*)
+ is an OR
* is a LOOP, it is optional, it may be done as many as a user wants.
i've tried many ways to solve the problem that my professor gave me but my knowledge isn't that enough to solve this problem..

I have seen on various websites how developers version their css/javascripts files by specifying querystrings similar to:
<head>
<link rel="stylesheet" href="css/style.css?v=1">
<script src="js/helper.js?v=1">
</head>
How is that done? Is it a good practice? I've been searching around but apparently, I'm not looking for the right terms. If it matters, I'm using ASP.NET.Edit:: I just noticed (via Firebug) that if I "version" my files (?v=1) they will always be loading and will always override the cache. Is there a way around that?

I'm trying to use the Response.Write() method to dynamically insert content in the < head > section of an aspx page. I need to inject a string value from a property on a code-behind object which is a link to my CSS file. However, it is not being processed properly at run time. The object is public on the class and is hydrated in the Page_Load() event. Down in the body of the page I can successfully inject other properties from the Corpoartion object with no problem at all.Why does this not work in the < head > section?This is the part that does not expand correctly:
<link href="<%= Corporation.PageStyleSheet %>" rel="stylesheet" type="text/css" />
Here is the entire < head > section:
<head runat="server">
<title></title>
<link href="<%= Corporation.PageStyleSheet %>" rel="stylesheet" type="text/css" />

Is it possible to set the property of a server tag from a c# expression, i.e. something like <asp:TextBox Width='<%= [some c# expression] %>'/> I though this would be pretty straightforward, but I can't get such an expression to run.

I'm writing a SQL query where I need to detect if the value of an integer column in one table is contained within the value of a varchar column of another table. For example:
Table1 has columns A, B, C
A = 1
B = 2
C = 3
Table2 has columns D, E, F
D = "1,2,3,4,5"
E = "2, 5, 10, 15"
F = "1, 3, 49"
How would I write SQL SELECT statement to determine if the value in Table1.A is in Table2.D, Table1.B is in Table2.E, and Table1.C is in Table2.F?

I'm trying to build a webpage without using any asp.net data binding controls ( listview, repeaters etc.)that I'm trying to do is to use stored procedure to get all necessary items, loop through them, and bind to labels, images etc.The problem is when i want to repeat .aspx code. I'm able to do everything i want in c#, but it's really pain to create all the necessary html elements such breaklines, spans, textboxes and so on.I tried to use expression builders, but it only repeats the last value from database.
Here is my code(ASPX):

I have a regular expression validation set on text box. I have a grid on the same page with edit and delete buttons. In some cases I don't want the regular expression to fire. For example, I have a scenario where the text box will be disabled but I can still enter data in to the grid and modify it, but the regular expression fires when I modify the grid and the changes in the grid are not processed.how can I stop the validation when I am working on grid. I can see a property causes validation for button to stop validation but don't know how can I stop for the grid.
