Lets take an example of online ticket booking system. Many users could be booking the tickets at any point of time. a GridView displays the list of Allotted and Free seats If a seat gets booked, this information must get updated in all the opened pages in user's browser. User need not require to refresh the page to see if a seat is booked or not Should i put GridView in update panel and keep looking into the databse constantly ??? This could turn out to be a heavy work if databse is too large any other alternative?? or should i stick with the above approach....?

I have a C# DotNet application and an SP of SQL Server 2005. I had made changes to the SP. I found that the connection string of database in the web.config also is correct and it is pointing to the same database in the same server but after changing the SP and checking form front end I am not able to get the updated SP results. After changing the SP do we need to build dll of middle tier again? What all changes I need to make. When I run the SP individually it is giving correct updated results. i had done IISRESET also after chnaging the SP.

View 15 RepliesI was reading through this post here http://www.misfitgeek.com/op-ed/adding-asp-net-membership-to-your-own-database and thought to my self what the common practice is. What do developers using ASP.NET membership and authorization in their applications recommend as a best practice? creating the membership tables in the same database that stores their applications data or configuring a second database to store ONLY the membership information?.
My current setup is a different database for membership information ONLY but am thinking that increases the number of databases i have to maintain. If I have 5 applications using asp.net membership, then that means 5 more asp.net membership databases. So do you normally create the asp.net membership tables in your main database or you configure a separate membership table? what do you recommend.

I'm trying to use a DataSet to maintain some rows for a table, and when I've finished my changes, send all changes to the database using a SqlDataAdapter.
I find if there are no rows in the table in the database then I am getting a 'Object reference not set to an instance of an object' when I try to access the table in the Dataset.
Is there a way to work with a Dataset like this ie. I start off with an empty table and I wish to add rows, to access the structure of the table rows, build rows, then add them and do the update on the SQLDataAdapter.

I want to add custom columns to some tables created by ASP.NET. For example; I need to add two fields such as FirstName and LastName to the aspnet_Membership table.
I can add this directly by editing the table but;
Is this the right thing to do (I mean; extending the table directly) OR should I create a separate table and hold the extra user data, there?How can I see these custom database fields as properties in code completion? example: membershipuser.FirstName;
I have created a search page which outputs results in a repeater. It uses a stored procedure to search a table %like a textbox value, what's the best way to make it search multiple tables and output the results on one button click?
As i could just use seperate stored procedures and repeaters for each table i want to search, which is only 2, but this seems inefficient.
I have 2 tables in SqlServer 2008.
Table1: T1id, SomeData
Table2: T2id, T1id, SomeData
I am using DataAdapter.FillSchema to create shema of tables in DataSet. I created DataRelation on columns
T1id in both tables.
Now when i try to Update Sql Database T1id in Table2 remains 0 and not the value of T1id in Table1.
I can successfully update Sql Database if i fill DataSet with records first (Using DataAdapter.Fill), but that's not what i want to do. I don't need "old" records in my dataset. I want to use dataset just to store all imputs from user until the proccess is done and then insert all those records "at the same time".
Is there any framework or tool to generate web services (WCF) access to all the non transactional tables in my database? something like asp.net dynamic data but with web services, I need to do this for homologation with other systems.
