I want to retreive some data from an SqlDataSource using it's Selected event I've tried
DataView dv = (DataView)SqlDataSource1.Select(DataSourceSelectArguments.Empty)
but here it's going into in infinite loop and then it gives me an StackOverflowException error in ASP.Net Development Server (my dev machine) and if I publish to IIS it requires me an user name and password to connect to server and gives an InternetExplorer error "Sys.WebForms.PageRequestManagerServerErrorException. An unknown error ... status code returned was 400. The SqlDataSource is in an UpdatePanel. Maybe this is why I get this.

how one would retrive a value stored among several values in a single database field?
For example, the MS Customize CreateUserWizard walkthrough [URL] adds the ability to save the users preference for subscribing to a newsletter and allowing their info to be shared as 1 value in the comment column of the membership database. The result ofaspnet_Membership.Comment is Subscribe=TRUE&ShareInfo=FALSE.
My question is if Subscribe=TRUE&ShareInfo=FALSE is in one field of the database, how would you retrieve just the Subscribe=TRUE value from the field and use it to send a newsletter to the proper users while ignoring the ShareInfo=FALSE value?

View 5 RepliesI need to retrieve data based on 3 different selections(current year, 5 years, 10 years). If the user select current year, then I need to pull data with the most up to date year, if the user selects 5 years, then I need to pull data for 5 years from the most up to date year in database. I am trying to accomplish this in sql due to using object DataTables in asp.net 3.5. I am able to do this with separate queries but I need to accomplish this with one query. I was going to use CASE statements but not really sure if I am approaching this correctly.
View 9 RepliesI want to retrieve sqldatasource row from database and if = 1/0 set checkbox to checked or not
I am using the sqldatasource and formview. The sqldatasource is bringing in 1 database item via querystring id
I want to read the row entitled 'IsCharacter' which is either 1 or 0 value. If it is 1 I want the checkbox in my formview to be checked. If it is 0, I want it to not be checked.
I could do this with a dropdownlist with value of 1 or 0 which would be easier for me, however, I don't think it would be as user friendly as a checkbox.
Perhaps a radiobuttonlist would be better?

Is there any method by which we can retrieve random data from a dataset or rather directly from a table.
For example, I have around 30 questions in my table, I just wanted to display 20 among them and that too in a random order without the same item repeating. Can we achieve this using SP or through some Dataset manipulation?
I have a page in my website where there is very little code-behind. I only have two lines of code in Page_Load() and the rest of the code is declarative ASP.NET code. I have a FormView control which uses a SqlDataSource to get some order information. The SqlDataSource calls a stored procedure called usp_GetOrderDetails, here's the code for the SqlDataSource:
[Code]....
<truncated>
What I want is to grab the screenshotId from the SqlDataSource when the usp_GetOrderDetails stored proc gets called and populate it into a field on the page called screenshotId. I then want to use this screenshotId to get an image from the database based on Id. populating the screenshotId field. How do I do this - do I need to have something like OnDataBound or something like that?
