Construct A Master-Details Form?
Jun 21, 2010
Im having some trouble to construct a Master-Details form. When I navigate through each record on the master nothing happens on the details. This is so even if there exit a relation between the two tables in the database and in the dataset between the data table. Can anyone provide me with some samples or examples of coding how to proceed?
Furthermore I have tried to programmatically create the relation but the following error occurs: child list for field cannot be created etc

I'm reading in an XML file, to a DataSet. This contains two tables and the relationship is automatically created. I'm using two DataGridViews in an attempt to display the master and detail data.
If I set the datasource of the grids as follows, then the detail view updates correctly:

I'm trying to get a details view in ASP.NET to display the details of the logged-in user only. I have been told to use:
select * from STAFF where USERNAME = user.identity.name
I thought this was too simple to be true and I was correct as it shows no data when I attempt to run.

I have 2 datagridviews on my form. One lists products and when you click on a product in the first datagridview the other lists tests for the selected product. I have a products table with a productid,productname and productcode. I have a tests table with a testid and a testname and I have a prodtests table with a prodtestid, productid, testid and a few other fields.
Public Class frmProducts
Dim myConstr As String
Private WithEvents ProductBindingSource As New BindingSource
Private WithEvents TestBindingSource As New BindingSource
Private Sub frmProducts_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code] .....
Also I need to add a combobox column to the second datagridview that is bound to my prodtests table and to list the testnames from the test table in a combobox. In my save button, should I just call both adapter.update methods to save all changes. I will add the appropriate update commands etc.

I have two forms, A and B, as master/detail forms. A has a grid and a button. When the button is clicked, B is instantiated and shown - at this point, B is a local variable. When stuff happens on B, I want to refresh the grid on A. I had intented to declare B WithEvents and have A monitor for when the event is raised, but that doesn't work, since B is decalred locally.

I have a basic data entry form using a binding navigator and a details form. I do the validation in the dataset on the columnchanged and tablenewrow events. These work, and I check the haserrors property before saving, however if the user gets an error, when they get back to the screen, the current item has moved. Ideally, I'd like to have it stay on the item with the error: Private Sub DSHW_FACILITYBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FACILITYBindingNavigatorSaveItem.Click

I am new to VB.net and have created a simple master detail windows form. I created a two table data set and then dropped the master table on the form as a continues form or a detail form with several text boxes to hold the data. The child form is a data grid.
test data that I have added directly to the database shows up with the proper parent child relationships on the form. I can also enter new records into the database using the parent only portion of my form.
When I attempt to enter a complete record with data in both the parent form and the child data grid I get this error. The INSERT statement conflicted with the FOREIGN KEY constraint
[Code]...
I have searched for a possible reason for this error but can not find any explanation. I have noted in earlier versions of VB.net you had to enter code to save the child record, but the VB 2010 code does not seem to use the same syntax so I assumed the UpdateAll eliminated the need for the extra code

Scenario: VB2010 express + Sql Server 2008 express.
I have a master/detail form where I can modify a record. With VB 2010, I use the new Table Adapter Manager which handles all Updates/Deletes against the database inside a Transaction. Question is that before I update the modified record (only the master one), I need to insert it in another table (history table). My question is how I make both insert and update inside the same Transaction. By code? Using Stored Procedure?

i have a master detail form with databound datagridviews.my detail datagridview is bound to FKFieldSubFieldLookupTableBindingSource and it shows the linked sub-fields when the main field changes. This datagrid has only one column which is the sub-field names column. this column type is ComboBox.here are this combobox details
DataSource = subFieldLookupBindingSource
DisplayMember = sub_field_name
value Member = sub_field_id
No Problem until here.When i click on the Cell combobox I get the list of all the sub-fields. I don't want this. because once a sub-field has been associated with a Master field, it should not be available for other Master fields.What i did was, In the SubFieldLookup Dataset, i added a query to get all those sub-fields which haven't been associated yet.but this clears up the detail datagrid and shows blank comboboxes where it is supposed to have the sub-fields.
I simplly want the master-detail mechanism to work and when i want to add a new sub-field, and click the combobox in sub-fields datagrid, i want to have only those sub-fields which are marked False in database in the column 'alreadyAssociated'.
