Refresh Table Adapter When I Have A Child Table Attached With Parent Table?
Dec 21, 2011
I have a data table whose one column is related to a column of another table. I have a listbox in a form which shows a column (which is sorted by another column value by ORDER clause) of the parent table and other columns are in textboxes. The child table is represented by a datagrid. When I add a new item in parent table and click save, the newly created item is listed at the bottom of the listbox violating my ORDER clause. When I wrote some codes to fill data again after updating, it shows an error message[code]...

I have a table (Projects) which is linked to projectVersions on projectID..projectVersions contains several columns on which I'd like to filter a returned project (and associated projectVersions) list. For example there is a "capacity" column and a "country" column. I am doing a filtered list of projects on one page and I'd like to include all projects where any one of the associated projectVersions has a capacity of 750ml and a country of "France" for example.It may be that a particular parameter is not set and so I pass a zero to indicate not to filter on that.I guess this needs some kind of subquery as when I try and do something like this: [code] it doesn't work as the "xxx" bit, being one-to-many, expects me to specify an item to get at the entities within and yet I want to query where ANY of the associated versions match one of the criteria.

Table structures:
Employees: EmployeeId(PK) , FirstName, LastName
CafeLogs: LogId (PK), CashierId, EmployeeId, Value, => CashierId and EmployeeId are the data from column EmployeeId of Empoyee table
Table relationship:
Employees 1:N CafeLogs (CashierId (FK))
[code]....
Right now I know how to select only LogId, Employee's name, and , Value, not with Cashier name yet.
Dim query = From log In db.CafeLogs _
Join emp In db.Employees On emp.EmployeeId Equals log.EmployeeId _
Select log.LogId, emp.FirsName, emp.LastName, log.Value

I have a situation where a database table is updated with records inside a loop. Every record in this table has a parent child relationship with another table. This child table is also updated subsequently inside the same loop.I am creating the datatable for Parent table and adding records inside the loop, but committing the records in the database (using SqlCommandBuilder) outside the loop only once.
Inside the loop I am also calling the function for updating records in the child table. Because the adaptor and datable objects are created inside the child table function, I need to commit records in child table inside the function only. So this happens before commit of parent table. Because there is a PK-FK constraint in the database, an error is generated.
Simplest solution would be to bring all code inside one function. But I don't want to do that. Besides this parent child relations can go upto any levels.

First I have 2 tables, for example Customer and Orders, and in the database there is a foreign key relation between both. For clarity Orders have a foreign key field to the primary key of Customers, thus Customer is the parent and Orders is the child table of the relation. My application is a Windows Form application, and I add a dataset to the project, in which I drop the 2 tables, and the relations between the 2 tables is automatic added. Now I will om a form loop through the Orders table (witch is the Child table) and show in a textbox some fields of the Orders table and also the Name field of the related record of the customers table. Regarding binding a textbox fo a Orders field I do it this way,
Dim myDs As New DataSet1
Dim myAdpCustomer As New DataSet1TableAdapters.CustomerTableAdapter
Dim myAdpOrders As New DataSet1TableAdapters.OrdersTableAdapter
myAdpCustomer.Fill(myDs.Customers)
myAdpOrders.Fill(myDs.Orders)
Dim myBindingSource As New BindingSource
myBindingSource.DataSource = myDs.Orders
myBindingNavigator.BindingSource = myBindingSource
TextBox1.DataBindings.Add("Text", myBindingSource, myDs.Orders.OrderIDColumn.ColumnName)
But now I can't find how to bind a textbox to a field of the Customers table witch is the Parent table of the relation.

I have a single table that holds my Categories
CatID, CatName, ParentID
I have often used this layout to show Root Categories where the ParentID IS NULL. I would like to be able to create a vertical Menu (using a repeater and an <UL><LI> that displays the Root Categories and ideally, a collapse panel that would expand with the subcategories. Given the above Table format, it is also easily possible to make the hierarchy unlimited.

To get an id value after a table insert into an Access database you do a SELECT @@IDENTITY. I would like to know if this will work if your INSERT query is a table adapter query? I created an INSERT query for a table in the dataset designer which is working. My concern is that if I make another query with SELECT @@IDENTITY it won't work because table adapters make a new connection each time. Can someone clear me up on this?

I have code in vb.net that was created using Visual Studio 2008. It has got queries done via data sets and table adapters. dsStagMyfileDesigner.vb and dsStagMyfile.xsd are the files having all the sql queries. They are code generated by using data table adapters I believe. Editing them might screw the system.

I'm currently trying to create a system which stores different cases for clients using Visual Studio 2010.When adding fields from the database a table adapter is automatically created.Me.TblMattersTableAdapter.Fill(Me.MJPAccessDataSet.tblMatters)Now my problem is that each case may be at a different stage. They are either 'Active', 'Closed' or 'Archived'.So my question, is there a way to filter these results? I've tried creating DataTable and only adding the archived cases but I couldn't get it to work. I was trying.
