DataSource Controls :: Assign Dataset Values Retrieved From Database To Session Variables
Aug 16, 2010
I am looking to retrieve data from a database and assign those values to class objects which in turn will be turned into session variables. I am using an object datasource to retrieve the data from the database but I cannot find anywhere that shows how to assign these values to variables. The data is returned in a dataset. There is the added problem that there will be mulitple items returned which will have to be assigned to different arraylists of objects based on the a primary key in the database.

I am looking to cache a dataset and then filter the results as they will be used repeatedly. However, I don't know how to assign values in the filtered dataset to variables in C#. I have looked on the internet for the past few hours but all I can get in binding the dataset to a control.

I recently installed the latest Oracle Data Provider for .NET(ODP.NET 11.2.0.1.2), due to the fact that Microsoft Oracle Client is deprecated. Ever since the new installation, my SqlDataSource control stopped working. When I try to configure the data source of the SqlDataSource and test the connection, it always gives me the following error message:Database schema could not be retrieved for this connection. Please make sure the connection settings are correct and that the database is online.
OCIEnvCreate failed with return code -1 but error message text was not available. at DataObjectSupport(721,6)
I know for sure the connection settings are definitely correct and the database is online for sure, because any databinding I did manually works perfectly well. I can manually bind to a Gridview, ListBox controls and display the data without any problem. The only problem I have is using the SqlDataSource. This is painful because Gridview and Listview have a lot of cool built-in features. When you databind the controls in the code behind file, you lose all the features.
I have added ASPNET to the Oracle home directory and granted it full control access and retarted the computer but it doesn't work. I'm using Visual Studio 2010 and the database is Oracle 10g. Does anybody know why I'm having problem with SqlDataSource only?

I hope I can explain myself properly. What i'd like to do is be able to add a Search form where users can search various criteria based on my Orders table. I was hoping to add the capability to click on one of the OrderID's to display the fields from the Orders in the various text boxes on my form. This would allow the users to search, and update all in the same page. I have the data retrieval portion down pat, but am not really sure how to give them useful links. Is this possible? Or is there a better approach that I could take?

I need to declare a variable xyz, then, using a select statement, pass a variable into it so I can then insert it into a table.
Dim @xyz As
Integer
set @xyz = (select xyz
from systable)
1. I get a squiggly line below the @.
2. I get informed that set and let are no longer supported.
3. When I remove the @ I get the squiggly below select.

I have a gridview in a page, and some Texboxes along with a button(for issuing a command) in the same page. The TextBoxs were inputted values and the values could be assigned to the selected row of the gridview, some fields are the same values along the rows, and the values are inputted in the TextBoxes for using several times without change.
Well, I need to know: how can I assign the values of the TextBoxes to the selected row of the gridview. in another words, how can I access the cell members of the gridview when it is in edit mode? (Q1)
If the row is not selected, I have no way to know which row should be assigned values, since there is no such things like "current row".
So, if the selecting button(or link) of the gridview is not selected, the button along with the TextBoxes should keep disabled, until a row's "Edit" button is clicked. (Q2: How can I find if the Edit button is clicked? I guess I can use the property "mode" of the gridview to indicate the situation. )
And the last question is (Q3), how can I ensure the values are updated to the database? Maybe I dont need to do more things than just click the uppdate button of the row of the gridview.

I've got some ASP pages where the session variable values get blown away BEFORE the session times out. I can't understand it. For example: if a user logs into my ASP app using his password which is stored in a session variable, it will be fully accessible for a few minutes and then all of a sudden.....Wham session variable with password value is gone. And the session timeout is far from expired. The session variable is not being touched in any way after it gets initialized with a value.

I have 5 textboxes in my webpage for entering address, i.e,
door no, village, city, district, pincode.
These are concatenated by comma (,) and stored into the database field address. at the time of retrieving, the concatenated address, should be separated and assign to each textboxes.

We are working in a web application using Session variables to store the clients ID to operate with them in all app (making orders, reports, etc....) but randomly users get the client ID of another user in any moment using the application.
I have tried to solve it in a first step adding to system.web section in the web.config file this:

ASP.NET State Service is running in server normally, It began run just before this last change, but we have not solved the problem either with this solution.
The server is Windows Server 2003 Standard Edition SP2 32bits running IIS 6.0, and the application is made with Framework 2.0

I'm fairly new to asp.net and I'm trying get my arms around the data entry and update. I have created a nice data entry formusing a stored procedure. It works well but for a test database, it's pretty much overkill, but worthwell in learning how. I'm going through the ADO.NET quick start tutorial and I've ran across a couple of questions that I've not be able to answer. In my website,I'm wanting to edit the database by creating a separate form that is filled with the existing database information for that particular id. My main question is how to I take the information from the dataset and get it into my form. The code below is not fillingmy form. Not sure what I should be using here:

I have successfully created a strongly typed dataset. And trying to assign my user input values to the columns of my StronglyTypedDataset but having no luck with it
[Code]....
In the above code 'PlantInventoryAccuracy' is the name of the Strongly Typed Dataset and 'PlantInventoryAccuracyDataTable' is the dataTable. when I try o debug this to see if my user input values are being assigned to te currentRow I see blue squuiggly line under the 'new' key word when I mouse hover it says
'The type PlantInventoryAccuracy.PlantInventoryAccuracyRow has no constructors defined.'
This is the first time I am trying to use Storngly typed datasets. I am not sure if I am trying to use it right. The above code is in my code behind page and my idea is to fill this row with the user input values then pass this to my data layer where I need to assign these values as the parameters to the stored procedure I have created and then store them to the database.

I'm working with an asp.net application that stores most data in a database and not session. I'm wondering of the pros and cons of each and which is the better way to go. For example, you have a pretty busy site and instead of storing user specific variables in session, there is a DB table called user data and it can store all user specific data that can be accessed from any page by querying the database. Which is the better way to go, session or database?
