Forms Data Controls :: Synchronize GridView With Database After Changes?

Jan 31, 2010

I have a Gridview that is populated with and ObjectDataSource set up to allow anonymous users to populate it. After logging in, the database is filled with the Gridview's data using the following:

[Code]....

The database's primary Key is filled by the "lblItemID" string at the beginning of the loop.

deleting the item from the database keying on this primary key. The gridview deletes the proper row using it's DeleteMethod, but obviously I don't have it set up properly to delete the same PK row from the database.

I really don't want to mess with the DataSource's DeleteMethod (and I'm not sure if this would help at all anyway), so is there a way to look for these deleted ItemId's and remove them from the database while executing this Loop statement?

Architecture :: How To Synchronize The Data With Server

Jun 23, 2010

I have the following scenario:

A server with a number of different clients on different networks. Clients will have to synchronize data with the server.

Just imagine we have a simple data table on the server. The client has the same table schema and works locally but at a certain time of the day it must upload and synchronize with the server.

Was thinking maybe in doing the following. On the client have two extra columns:

Ej:

- synchronized (Boolean, default to false)
- Time it was synchronized (date time).
- Have a wcf service on the server.

Whenever it needs to synchronize it calls the service. The service then updates data on the server. The client will wait for a response which will inform whether the synchronization took place or not. If it did it updates its local table, setting synchronized to true and the time.

DataSource Controls :: Can Synchronize The Design Of Two Databases

Jan 17, 2010

I used the Database Publishing Wizard to create a copy of my live SQL Server database for testing purposes. Both the live and test databases are hosted by my ISP.

What is the easiest way to transfer design changes from one database to the other without altering the data (assuming that the design changes are compatible with the existing data in the target database)?

Any proposed solution would have to be available via Visual Web Developer 2008 Express or SQL Server 2008 Development Edition.

Forms Data Controls :: Gridview Recalculate, Then Repopulate Gridview Without Going Back To Database?

Mar 26, 2010

I want to make sure I go about this in an efficient manner. I have a gridview. On the gridview, I have some columns that are read only values . These values go through calculations based on values in a database. The stored procedure takes information in the database, does some simply calculations (this value * that value / another value type of stuff) then returns a recordset as a datasource for the grid.

Other columns on the gridview have values the users can enter data. I want to be able to provide a recalculate button that will run calculations based on the entered values which will change the readonly values and then repopulate the gridview's read only values without going back to the database. This recalculate button is not the save to the database button. The save to the database button will take the values in the user entered columns and save them to the database. Then, the next time the grid is called, the page calls to the database and loads the grid.

So, what I'm looking to do is allows for recalculations on a gridview, a gridview with about 24 columns and about 1000 rows. My first thought is to create a class that reads the gridview and then applies the business rules, then updates the gridview some how. Or, maybe have a dataset table thats i read the value from the user inputs, then apply business rules and then bind the gridview to the dataset table. Do any of you have thoughts here, maybe have done something like this?

Web Forms :: How To Synchronize Users Requests / Threads

Feb 6, 2011

I have what I consider a pretty complex situation that I am not sure if it can even be accomplished via an ASP.NET web application. (I am using aps.net 4.0) But what I want to do is design a "online auction site" that can handle many autions running at the same time. So I can only imagine eBay and all the other millions of auction sites out there are all doing this someway or another. My biggest concern is that I want to make sure the design here to make the site as effiecent as possible. Here is specifically what I am trying to figure out.

I think I need to create an object (per active auction) that stays in memory for the life of the auction. This object would have at least the following information:

Aution ID, time remaining, highest bidder id, bid price, Thread Control Variable, etc...

Now here is the tricky part that I think is vital for auction sites. Lets say you have 500 users on my website that are all watching the same auction and it is getting down to the last second of the auction and they all click to place a bid at the same time. Keep in mind this may also be at the same time hundreds of other users are placing bids for other auctions going on all at the same time.

How do I get all these requests (bids), for a single auction, lined up so that they are processed "one at a time"? But some how I need to be able to make all requests wait in a queue until it is their "turn" then I would need to be able to update the in memory object, write a record into a SQL database and then begin returning information back to each user.

Based on other development languages I have used in the past I know their were objects that I could create that could be used to get multiple threads to run in order (in other words syncronized). Usually it would be a case where I would be listening on a server socket and could do something like ThreadVariable.Lock, <process the request>, thenThreadVariable.Unlock. What that would do, is force all threads that tried to call ThreadVariable.Lock to wait until no other threads had the variable locked then it could proceed. Obviously the code it processes between the lock and unlock should be as quick and effecient as possible so it does not create a major traffic jam.

Because my thinking is this "object" I am referring to as being in memory, most likely will play a big role in answering the question about getting the requests in a "one at a time" situation it may be the focus of the question is more like how would I create "an object" and store it in memory to be quickly and easily accessed?

And even more generically does this even sound like I am on the right track

I think the topic of "communication to and from users" will need to be a completly different thread.

Forms Data Controls :: Updating Encrypted Data To SQLServer Database With GridView

May 31, 2010

I'm just wondering if anyone has come across a good, easy method for updating a SQL Server 2000 DB table using the edit feature in GridView. The catch here is that I need it to encrypt, send to database, then decrypt when the page calls it to be displayed. I have successfully implemented an insert method using FormView with encryption. For some reason, I just can't seem to figure out the edit/update.
