Forms Data Controls :: Using Formview, Tables, And Access Database Along With The BLL & DAL Model?

Jul 7, 2010

Really new to C# & Web developing - but have used the DAL & BLL model from a number of the turorials. Have a situation that I not sure the best way to accomplish. I have an application dealing with courses, books, etc. utilizing an Access Database. All was going well in creating an on-line catalog using Formview and tables to display the db values stored in the Course Table (Course ID the key). User is able to use dropdown list to locate the course - dropdown list showed the Course Nbr & Name, but used the Course ID to get the detail. This issue appeared when they introduced a Prerequisite field in the Course Table. This contains the Course ID of the prerequisite course, but they want to display the Course Nbr and Name in the table field. So today it show 18 (Course ID) and they want B101 Intro to Biology. Hope I have provided enough information of what the code looks like below


<asp:FormView ID="FVGeeralidades" runat="server" DataKeyNames="ClaveAsignaturas"
<asp:TableRow ID="TableRow5" runat="server">
<asp:TableCell ID="TableCell11" runat="server" HorizontalAlign="Left" Text="<STRONG>1.6</STRONG> Prerrequisito"
<asp:TableCell ID="TableCell12" runat="server"></asp:TableCell>
<asp:TableCell ID="PrerrequisitoValue" runat="server" HorizontalAlign="Left">
<%# Eval("AsignaturaPrerrequisito")%>

Here is also the OBJECT DATA SOURCE
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server" OldValuesParameterFormatString="original_{0}"
SelectMethod="GetCourseByCourseID" TypeName="CoursesBLL">
<asp:ControlParameter ControlID="DDLCourse" Name="CourseID" PropertyName="SelectedValue"
Type="String" />

DataSource Controls :: Tables For Particular Presentation Of Data

Jun 29, 2010

Apologies if this is in the incorrect forum.. just a question about how to best structure some tables for a particular presentation of data. In the following table (2nd column) you'll see that each motorcycle product applies to a range of years. What is the best way to store this range of years in a relational db? At the moment I have a datefrom and a dateto field for the two ranges, but that may complicate things when I want to filter the table by a particular year. E.G. datefrom is 2006 & dateto is 2010 and I would like to filter by products for a 2008 model.

DataSource Controls :: Combine Data From 2 Tables

Mar 27, 2010

I have 2 tables with UserId and FirstName, LastName Columns that I want to combine the data in a Select Statement or Stored Procedure

1. The 2 tables will never have the same data, each table will be distinct

2. I want to combine first and lastnames to a full name (t1.FirstName + ' ' + t1.LastName) AS FullName

3. The statement will be used to populate a dropdownlist with UserId as Value, and Name as text

I am unsure how to accomplish this since I do not need to connect the tables, but combine the Sum of their data.

DataSource Controls :: Adding The Same Data Values Into 2 Tables

Apr 23, 2010

i have an insert statement, and what i would like to do iswhen the value of table1 is entered, that value enters into table 2, so for example, heres my insert statement

INSERT INTO Cards (Name, Desc, id) VALUES ( @Name, @Desc, @id) INSERT INTO CardTP (NameSet, Desc, id)

Now, what i would like to do is that, i will specify all those individual values myself, BUT, when it now comes to the "id" field, when an id is entered for the "Cards" table, the SAME id should also be entered in the id column of the "CardTP" table. how i could enter the value of one table, into another tables row (having the same value) as i want the Cards and CardsTP table to be related in the id fields.

I have hard time trying to find the solution to retrieve data from multiple tables in one database.

Kategorije.idKategorijais joined with Clanak.idKategorija, but that isn't the solution because I want my web site to show the Kategorije.naziv instead of Kategorije.idKategorija. This is the code I'm currently using to get idKategorije shown on my web site:

DataSource Controls :: Sum Data From Two Columns In Different Tables - SQL Query

Feb 9, 2010

I am trying to create an application in which there is a summary of outstanding payments.

One table is Table_Bills.

The other table stores records of Payments made and is called Table_Payments.

In summary i want to show 3 figures - each in separate one field datagridview with a data_source in separate data_adapter:

The first two are no problem but the last is giving me a headache.

DataSource Controls :: Left Join 2 Data Tables?

Jan 29, 2010

I have 2 different datatables. 2 datatables from 2 different servers.

My first datatable is this:

SELECT DISTINCT, a.create_date, a.Modify_Date, a.Object_Id
FROM dbname.sys.objects a

and my 2nd datatable is the same, but from a different server connection string

SELECT DISTINCT, b.create_date, b.Modify_Date, b.Object_Id
FROM dbName.sys.objects b

Basically, I want to compare which procedures are on one server and not the other (dev and prod)

So after I have my 2 datatables i want to create a data relationship on the name and then do a left join to see whats in a and not b.

DataSource Controls :: Filtering Data Based On Multiple Tables?

Mar 16, 2010

I am writting a directory website that advertises fitness classes. These classes are listed by Class Type, and Geographical Area. Each Class Type can satisfy one or more of four Fitness Goals such as Loose Weight etc...

I have a table for Classes (classid, classname, classdesc, classtypeid, geoareaid) I have a table for geographic areas (geoareaid, geoarea) And I have a table for ClassTypes (classtypeid, classtypename, classtypedesc)

Which obviously links geographic area via the classes.geoareaid as a forgien key and classtypes by classes.classtypeid as a forgien key.

I can list all classes by type and also by geo area no problem, the problem arrises when I then also want to filter by goal.

The Goals Table (goalid, goal, goaldesc) is linked to the classtypes table via another table classtypes_goals (classtypeid, goalid) as each classtype can satisfy any of the 4 goals.

I am using a DataSet to fetch the data from a Stored Procedure in the SQL Database but because the classtypes can be linked to multiple goals I am getting duplication in my list depending on how many goals a classtype satisfies.

All I need in my data list is class name, class type and area I don't even need to display the goal I just want a drop down above the table that will filter the list and show only classes of classtype that satisfy the goal chosen.

DataSource Controls :: Deleting Data From The Multiple SQL Tables With LINQ (C#)?

Apr 22, 2010

I'm looking for ideas on deleting data from the multiple SQL tables with LINQ (C#).

My existing solution does the following:

1. DeleteAllOnSubmit( Subset of the data from the child table)

2. DeleteAllOnSubmit( Subset of the data from another child table)

3. DeleteAllOnSubmit( Data from the parent table)

4. CommitChanges()

All this resides within a single method, which makes it ugly and not re-usable.

I have considered the following alternatives, but I decided not to use them:

1. Cascade delete on the tables.

2. Do a join on all tables from which I will remove the data, but I'm not sure yet whether I could pass a join query to DeleteAllOnSubmit().

3. Write stored procedure(s) to delete data from each table. I don't have the time to implement this due to a large number of tables and the time constraints.

Oop - Use Data Access Classes (Converting From ColdFusion)

Feb 17, 2011

We're converting from ColdFusion to ASP.NET 4.0 and we just don't know which route to take with setting up our classes.

In college I was taught to break everything up into separate Data Access Classes and Entity Classes that speak to the DAC. To me, that's the best option for a team that needs a lot of control over their classes and needs to reuse multiple items.

Then there is LINQ... Sure.. It's great and fast! I have no problems writing my own queries though. To me, it's not something I really need.

I would think we should be using folders that contain our DAClasses and folders that contain our Entity Classes. Then we would have our actual .aspx presentation pages.
