My question of "selected gridview1 data swap in gridview2 on button click and vice versa" but did not used the DB connection for that.
I want the same problem to be implemented using database connection i.e values in gridview1 should come from database table and then swapping shold be done from gridview1 into gridview using the 2 buttons.
is there a way to swap rows in a gridview up and down. if so, what would be the easiest way to do this?

View 1 RepliesI am using VS2008 and oracle 10g ODP.Net. The oracle database that I used in the connection is working and tested it using sql plus.The connection string when used in a GriDView works perfectly. Now when I created a new listview control with the same connection it gives an error.Database schema could not be retrieved for this connection. Please make sure connection settings are correct and the database is online
Object reference not set to an instance of an object at VSDataObjectSupport (478,6)
change the connection between data controls and database table?
View 2 RepliesI'm currently developing an ASP.net application w/ VB as the code behind. I have a page that shows all the user name currently assigned to the system. The problem now is that the page does not communicate directly to the database. Instead, I use HTTPrequest to get all the user names from a different sever. Now I want to populate the listview control w/ the response that I got (and not directly from the database).

I'm having a problem, which I haven't had with other projects, in setting up membership. I have set up a aspnetdb database using the asp.net confirguration tool. The database is in the app data folder and I can set up users and roles etc from the web site administration tool. However, trying to log in within the application, using the login control I get "Login attempt was not successful".
I have noted the following :-
1. On the home page of the Web site administration tool the application:/ shows no application where as normally it would show the name of the application.
2. Clicking the AspNetSqlProvider test button, I get the error "could not establish a connection to the database"
3. Although various lines have been added to the web config file, no connection string has been created to the aspnetdb file in the app data folder.
4. If you right click on the aspnetdb file within the solution explorer, there is an option of "include in project". Selecting this doesn't however solve the problem.
I'm trying to weigh up which is the better most reliable database connection for use on a vb.net/ms sql site. I've previously experienced problems catching and closing db connections with the using statement if an error occurs, but do like the fact it doesn't need to use any global variables. Both examples use a general Database class file which opens and closes a connection.my current examples are: TRY CATCH EXAMPLE:

I try to connect my database for so long so i wrote two type of codes. Let's discuse first on.
I have database called PhoneDirectory.
It have only one table named Residents.
I have button wiht ID="Button1".
I want when i click this button to see all of my residents.
I want to see the result in DetailsView and to be able to edin, delete and add new resident.
First try with SqlDataSource so i wrote this:
<asp:SqlDataSource ID="Resident Details" runat="server" ProviderName="System.Data.SqlClient" ConnectionStrings="<%$ ConnectionStrings:ThisIsTheConnection%>"
I am using a adapted version ofhttp://www.mikesdotnetting.com/Article/45/Programmatically-accessing-data-from-DataSource-controlsDon't we need something like a closing-routine / close connection command after getting data from the database?If yes: What is the correct closing command?
View 2 RepliesMy website is working but when I host it up, the connection are all screw up. Is it because my connectionString are all linked via SqlDatasource and is for local files only?

View 11 RepliesI am designing a web application and have separate layers for UI, BAL, DAL and DB, while using custom business objects and collections. The app will be used by over 10,000 + registered used and it becoming more complex as I add new functionality such as inline editing and batch processing of collections with transactions ... which has me up late at night trying to design the best approach for this ...In some UI web forms, I bind say 3 controls to 3 different collections. The UI calls the BAL classes for the required collections, then binds the collection returned. So for each collection I want, a db connection is opened and closed. As I understand database connectivity adds overhead so Is there anyway I can design this so 1 database connection is created for a unit of work in a 3-tier or n-tier architecture?

View 1 Repliesam writing a series of WSS/MOSS webparts amongst which one will need to detect the current SQL Server database connection, prompt the user to setup a new connectionstring, and fire appropriate stored procedures to create a new database if needed. The user needs to be presented a textbox or label control with the current database connection. I've never had to detect current database connection, what methods do I call for this? If the desirable connection is not present, the web application needs to prompt the user to make a new database. The user really won't make the database, they simply need to click the command button which will fire the stored procedure to create the database.
View 1 RepliesI 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?

I'm using an ODBC connection to connect a SQL 2005 database to my ASP.NET app in Visual Web Developer Express. I'm finding that the expected functionality that tutorials review does not work for ODBC connected databases the same way as it does for SQL databases created in the Web Developer. For example, I can't use stored procedures because the option to create one is disabled in the Web Developer, and if I create the stored procedure in SQL Server Management Studio Express, it doesn't show up in Web Developer because Web Developer only finds the system stored procedures, not the user-defined ones. I've seen other cases as well where database management options in Web Developer don't work with ODBC databases.
Am I missing something in my setup, or is there an inherent limitation with ODBC connected databases? Or, is this a limitation with using the Express versions of these development tools?
