why I couldn't get the variable from the URL.
<meta property="og:title" content="<% Response.Write(Request.QueryString["title"]); %>"/>
For some reason the code, <% Response.Write(Request.QueryString["title"]); %>, does not retrieve the data in this case. It works fine if I put it in the title tag though.
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">

I am unable to capture the textbox in JavaScript
I have a page where it is getting overwhelmed with code like:ar textBox = $get("<%=textState.ClientID%>");This requires me to have my JavaScript inside the page instead of nicely tucked in a js file. Is there a better approach to this?
document.getElementById doesn't work because then I end up with code like this:
var textBox = document.getElementById("originDestinationControl_textState");
var textBox = document.getElementById("ctl00_ContentPlaceHolder_originDestinationControl_textState");
So far it seems like I get something figured out then run into another issue... Anyways, I was finally able to grab an ID from a table and enter the value into a Label using this code:
[Code]....
Now i want to make things trickier by grabbing the last value enterd. Now there will possibly be multiple people using the application simultaneously, i think it is still possible to do this. Here is the statement that enters VALUES into the table that generates the CaseID that i want to grab from:

From what i have researched, I may need to do a WHERE some where to grab the @@IDENTITY. I am having trouble figuring out where the @@IDENTITY goes, and possibly the correct syntax as well.
I have a registration form which is working perfectly well, I need to enhance it slightly from where it is. As it is users are able to register for an account wether the email has been previously used/allocated in the user db.A client side call to the IsEmailAvailable function works great, just not working correctly server side. Here is the code.
My function:
[Code]....
And my if statement:

So my question is, how can I pass the end value of the IsEmailAvailable function to my if statement correctly.
I'm using asp.net - I need to grab live data from a website. Here's an example:

That website provides live data share prices. I need code to retrieve the share price from the website and display it in my own page. I know you can get share price widgets online but all I need is a simple way to retrieve the share price values.
I have a number of 0-12345-67890 and I want to capture 0123456789 in a named capture group. I got this far:
@"(?<upc>d-d{5}-d{5})"
Which captures the string as-is. How do you skip the dashes while grabbing the number as a single named group? BTW, this is ASP.NET Regex.
In one of my web app's pages, the code behind needs to grab the UserId of the person logged in, so that it can then be inserted into a table which was added to the original aspnetdb.mdf. This table contains a column with a uniqueidentifier primary key which is in direct relationship with the aspnet_Users table; however I seem to have trouble retrieving the UserId. This table contains the additional information of a user which is not included in the provider, and it has a one-to-one relationship with aspnet_Users.
I hope this makes sense. I haven't written any code for it yet; I'm only at the thinking part of this stage. But my mind keeps going blank.(perhaps I need a break from the solution???).
I am using C# in my Web app's code behind.
I created a base Controller for the other Controllers to derrive from, and in that controller I overrode the OnActionExecuting method so that each time any Controller executes a method, I can run some code. In that code I added a value to ViewData, and in the Master View I want to either display certain items or not based on the value of the ViewData item set. The problem is, once I get to the Master View, the ViewData doesn't have anything in it. I am not sure what I'm doing wrong.

I have a Gridview where some columns are populated with numbers of type nvarchar() and some columns are filled with numbers of type int I am trying to grab the a cell from a selected row that corresponds to a Table's KeyID and assign it to a label like so:
Label1.Text = MyGridview.SelectedRow.Cells(8).Text.ToString
Problem: If the Gridview column 8 has numbers of type nvarchar() it works fine But if column 8 has numbers of type int , it does not work. It's probably simple, but I dont see it.

View 16 Replieswhats the exact use of static variables in overall programming in .net and for asp.net...
Recently i went for the interview where interviewer asked me 2 question which i was not sure for the same..
whats the use of session object, i said sessions are the server side object, they are used when you want to store user specific data at server side, then he asked what if i want to use static variables for the same, i was mum, can anyone tell me how asp.net will behave if i store the user specific information in static variables.If i use cookies which are the best option to store the data at client side (not sensitive one), but what if user has disabled cookies on his machine, will my application would crash.

But if I pass the IP2 as shown in the line commented out, it tells me No such host is found. It's like it thinks "IP2" is the host name. How can I pass a variable in there?

Aif i have a choice between static veriable and session for just storing an integer which one of these should i prefer??
I have some WCF services. These services run in ASP.NET. I want these services to be able to access a static variable. My problem is, I'm not sure where the appropriate server level storage mechanism is. I don't want to use the database because of speed. But, I want the static variables to stay in memory as long as possible. In fact, I'd like it to stay until I restart my server if it all possible.
