Forms Data Controls :: Retrieving Data From Database To Populate CheckBoxList - C#
Feb 24, 2011 I am somewhat new at C# so forgive me if I have something listed wrong. This is what I got:
I am working on a school project designing a car dealership website. I have an inventory list that allows you to edit any car in the inventory. When you click on the edit button it takes you to the edit page and populates the controls with selections from the database. I have an options table that stores the VehicleID and Option ID. When the page loads it fills all the DropDownLists for the vehicle info with the data and selects the correct item according to the database selection but the CheckBoxList does not select the items that are on the Options table. I checked the query in SSMS and it returns the correct data. I have stepped through the method and it works till the "(currentCheckBox != null) if statement. It doesn't throw any errors but it also doesn't select items when the page renders.
I thought it might have been something with the page life cycle since databound controls don't render until the end but the DropDown's I have fill and selects the correct item according to the database.

LINQ-to-SQL Retrieving Data From A Different Query!
Jun 28, 2010I have a web application that uses LINQ-to-SQL. It has a very strange issue, where a LINQ command retrieves the data that is supposed to be returned by another, totally different query that runs in a different thread. What could be the cause of this?
Specifically, a user accesses the application from his machine, opening a certain page. At the same time, another user accesses a different page from his (different) machine. One of the queries throws an exception, while the other returns the data of the first one, which comes from a very different table!
The case is always reproducible, whenever we stress the application with these two users. I've checked but I don't see any shared variables of any kind. What else could the problem be? What should I be looking for?

DataSource Controls :: Data Retrieving And Checking Queries?
Jul 28, 2010I'm currently working on a FOREX Live Trading project that I'm implementing.
I already have a database that stores the CURRENCY PAIR, BUY/SELL, PRICE AND QTY.
But I have a huge problem.
Scenario that is:
A person BUYS EUR/USD at a PRICE of 1.29900 @ quantity 100,000. (This will be recorded in the database table)
Then he BUYS EUR/USD at a PRICE of 1.29950 @ quantity 100,000. (This will then be recorded in the database also)
Then he decides to SELL his EUR/USD at a PRICE of 1.31000 @ quantity 200,000 all out. (How can I check from the database if he previously had make a transaction of BUY/SELL, so that I can do my necessary calculations for the P/L Statement)

DataSource Controls :: Retrieving And Displaying Only Current User's Data?
Jan 21, 2010Having trouble with a web page and connecting to SQL DB. Basically I have a form view table connected up to a SQLDataSourceControl and what I want displayed in the form is only data that has been assigned to the user that is logged on now. I have a "ViewAll" page, which lists EVERY field, regardless of who it is assigned to, but the "MyTasks" page should only retrieve the data of the current user.
I have two tables in my DB, the "Users" table, with user data (including an ID number) - this is used again in the "Tasks" table as a foreign key called "AssignTo". Therefore if user Joe Bloggs with ID number 5 logs on, whenever someone assigns a task to him, they will select number 5 in the "Task" table, as this relates to his User ID.

DataSource Controls :: Retrieving SQL Filestream Data With Visual Studio SQLDataSource?
Jun 4, 2010Is there anything special you have to do to retrieve Filestream data using a SqlDataSource? I'm using VB and have this as my sqldatasource:
<asp:SqlDataSource ID="SqlDataSourceReadPD" runat="server" etc...
SelectCommand="SELECT [PDIPAttachment] FROM [PositionDescriptions] WHERE ([CP_IDString] = @CP_IDString)">
<SelectParameters>
<asp:Parameter Name="CP_IDString" Type="String" />
</SelectParameters>
</asp:SqlDataSource>
PDIPAttachment is a FILESTREAM column in my table called PositionDescriptions
and this is some of my VB cod:
Dim dv As DataView = DirectCast(SqlDataSourceReadPD.Select(DataSourceSelectArguments.Empty), DataView)
Dim dr As DataRowView
For Each dr In dv
Dim data as Byte() = System.Text.Encoding.ASCII.GetBytes(dr("PDIPAttachment").ToString())
Next
The Filestream data has a PDF file in it, but what I"m getting back in "data" are 13 bytes consisting of: "System.Byte[]".

Mar 16, 2011On my webpage, jobs.aspx, I have a gridview which is populated from my database. I would like it so that when a row in the gridview is clicked, the ID of the row from my database can then be passed through as a query string to a second webpage, details.aspx, where more information about what was clicked on will be displayed.
