Working on a heavy ajax based site with over 100 methods from all the ajax calls inside each of each controller all with basically the same code.Was thinking of changing them to a big case statement for readability which would keep the code a bit more dry and make it easier to read.What I am wondering is: Will there be a performance hit and is there a better way to deal with it?

View 4 RepliesI have been working on a stored procedure to calculate likert scales for course evaluations. I have the stored procedure done but I ran into an interesting but frustrating situation.
I used a case statement along with a select query to count the number of responses of a given value. Likert scales are usually 5 point scales 5 being the highest and 1 being the lowest. The value that gave me the trouble was null values. In my evaluation page the instert query puts a null value in the field instead of leaving the response blank. These are the two queries I used both are syntactically correct but one works and the other doesn't. #1 Null query that works
[Code]....
Can anyone explain the differences and why one works but the other doesn't? Can it be as simple as switching the WHEN and the column name and if it is would it be advisable the other ones around?

I'm facing a problem in our current running application. There is a table in database which has 67 columns,among these 18 columns are nvarchar(max) datatype and contains 30K records. Problem is now that SELECT * FROM myTable it takes around 3 to 4 seconds. Which is degrading our application's performance.
View 12 Repliesi have a FormView, it renders fields from a SQLServer database but also much static text specific to the database value I get. I dont know if this can be done in the code behind and put all this in a function . I put it in my formview
<ItemTemplate>
<% If Eval("Feature1") = "Yes" Then %>
<%# Eval("Username") %> A lot of text
<% elseIf Eval("Feature1") = "No" Then %>
<%# Eval("Username") %>
A lot of different text
<% End If %>
</ItemTemplate>
If I do the code above I get error message:
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control. Can this be done within the formview?
I have a sql datasource with the ControlParameter called ddlDropDownList.

I am working on a website in which more than a thousand users can login at a time and there may be more than 50000 total users. I am worried about the performance of the application in case of concurrent access.
what is the best way to manage that, so that my application runs without any performance issues.
I'm running a ASP.NET website on my development box (.NET 2.0 on Vista/IIS7).
The Session_Start method in global.asax.cs logs every call to a file (log4net).
The Session_End method also logs every call.
I'm using InProc session state, and set the session timeout to 5 mins (to avoid waiting for 20 mins).
I hit the website, wait for 5 minutes unit I see the Session_End logging. Then I F5 the website. The browsers still has the session cookie and sends it to the server. Session_Start is called and a new session is created using the same session id (btw: I need this to be the same session id, because it is used to store data in database).
Result:
Every time I hit F5 on a previously ended session, the Session_Start method is called.
When I open a different browser, the Session_Start method is called just once. Then after 5 minutes the Session_End each F5 causes the Session_Start method to execute.
Update:
After the Session timeout, all subsequent requests have a session start & session end. So in the end my question is: why are the sessions on these subsequent request closed immediatly?

I wanted to create a CurrentUser object to be accessible in every Action of Controller, I initialized it in Constructor but User.Identity was not available in Constructor. I followed the following link on stackoverflow:
Defining a User with User.Identity.Name in controller constructor
But after inheriting my Controllers from BaseController, my Action methods are not even executed, the execution stops at Execute of BaseController and I get blank pages in the browser.

View 4 RepliesI want to insert a large amount( approx 7000 records) of data into a table, My scenarios is that i need to check whether the record already exists then it will not insert it. Currently i am using a stored procedure for this which gets called for each record.
IF EXISTS(SELECT 'True' FROM MYTABLE WHERE ID = @ID)
BEGIN
--This means it exists, return it to ASP and tell us
SELECT 'This record already exists!'
END
ELSE
BEGIN
--This means the record isn't in there already, let's go ahead and add it

View 1 RepliesI have an ASP.net VB Web app I'm working on that has a requirement to provide a list of all our component part numbers to our engineers for selection into a custom Bill of Materials for reworking of an assembly. The list of part numbers is currently generated from a stored proc in our MRP systems/SQL database. The number of records being generated is slightly over 39K part numbers.
Although the SP only takes a few seconds to generate the data the web page is taking a couple of minutes to load, primarily because of the time to fill the control presenting the records to the engineers. I've bound the data to a combobox control to the engineer. They want to be able to type the first few characters of the part number if they know it and have the list filtered or be able to just scroll the data to find the part they are looking for.
I've read elsewhere that they may be a way to only populate a certain quantity of records rather than all 39K then filter based on the users actions. Unfortunately the discussions about doing this didn't provide any examples, references, etc.
My questions are these...
Is there a better way to handle this quantity of records than a stored proc and combobox? A
ny examples of a method to populate a certain number of records then filter based on user action?
