I use a simple master-detail form using Visual basic 2005 express edition and ms sql server 2005 express edition, as well.
The master table is dept (deptno int, dname nvarchar(50)) .
The deail table is emp (empno int, deptno int, ename nvarchar(50)).
The primary key for the dept table is deptno and for the emp table is empno.
There is also a foreign key (deptno on emp table).
I created a new project, connected to a db (called test.mdf) and created a data source consisting the two of the above reffered tables.
I dragged and dropped these tables on the form and i noticed the following:
1)When the form opens... the system queries the database and displays the data on each block on the form.
2)I insert and/or update a record on the master table (dept) and everything goes well...
3)I try to insert and/or update a record on the detail table (emp) and nothing is changed on the detail table - without any error.
4)When i try to insert and/or update a record on the detail table (emp) which violates the primary key constraint or foreign key the system complaints...(as expected).
I have a large form that is set up from master-detail datasets in Visual Studio 2008.I havene master table with a large amount of detail tables. Several of the detail tables also have detail tables linked.Now I need to add a master table that sits on top of my existing master table making it a detail table.
View 7 RepliesI am using MS-SQL and I am trying to write a query which fetches rows from the master table and related rows from the detail table. Now, the thing I want is that it must only fetch the first row from the master table and related field from the detail tables should be blank in that first row, now if there are related rows found in the detail tables, they must be shown in the separate rows. I have been trying using the following query but it is not giving the desired result.

I would like to know how I can make this happen?
When I double click on a row on a datagrid, a form will appear like the above screenshot.
When I double click on the row which consist of Brian/Kendall, a form will appear and should show Brian in the First Name text box and Kendall should appear in the Last Name textbox.
I have a product table with ProductId,ProductName,ProductCode as fields. I've populated a combobox with productnames. Next I have two other tables called Result_Header and Result_Detail. The Result_Header table has ProductId as a foreign key and BatchNo,TestDate etc. The Result_Detail table has ResultId as a foreign key which is the ResultHeaders Primary Key and other fields such as Result,SpecHi etc. What I need is when I select a Product from my combobox my two datagridviews must be populated via the Result_header and Result_detail tables respectively.

I have made several posts on here lately regarding master/detail or parent/child data setups but no one has been able to help. It seems like a subject people don't like to tackle BUT I really need help.
I'm having a real hard with the DataView.RowFilter functionality and it is driving me insane.
For the most part, I have the basic master/detail functionality working. When you select a record in the first grid, it shows the correct data in the second grid. When you enter a record in the first grid, you can enter related data in the second grid. I accomplish this by using a dataview and row filter bound to the 2nd grid. When you change the record in the first grid, the rowfilter for the 2nd grid is restated and reapplied.
The problem arises when I overwrite the primary field value in the first grid and the detail records become orphaned. You would think all I have to do is change the ID in the 2nd grid to match the new ID in the 1st grid but this is where I am having problems. I wrote a loop to change the ID of each record currently loaded in the 2nd grid to match the newly changed ID in the first grid. The code is here:
Code:
Dim I As Integer
For I = AuthorizationGroupsDGV.Rows.Count - 2 To 0 Step -1
AuthorizationGroupsDGV.Rows(I).Cells(0).Value = StrEmployeeID
Next
I have used this code before and it works great. It has to step backwards through the grid because when the ID's are changed, they no longer match the RowFilter criteria and they disappear from the grid. They still exist in the dataset. The problem is, while the code "works" the intended effect does not. Some of the records completely disappear from the dataset and do not reload when I restate the row filter against the new ID number.
There are a lot of master/detail databinding examples with detail form on the same window than the master, I can't find any example where detail is in a new window.

I have a dataset containing 2 tables,Customers and Contacts. Just showing the master-detail is not a problem. Problem occurs when I try to search the master table to bring in the detail table. Searching the master table shows only the master record, but not the related detail records. Adding a 'findby' query on the detail table only shows the records.url.. Normally when the master table is filled, the detail record shows in a form.

View 1 RepliesI can do this easily with table adapter, but I can't seem to use variables in the table adapters connection string, or specify the connection string to use before "filling". Is there a way to populate the form without using any sort of binding? Currently I've used this method - a search form that populates a list box, and on the double click action I have this:
Private Sub lstResults_CellMouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles lstResults.CellMouseDoubleClick
'Fills Main Form
Dim firstcellvalue As String = lstResults.Rows(e.RowIndex).Cells(0).Value.ToString()
frm_IMT.intPendingID = CInt(lstResults.Rows(e.RowIndex).Cells(0).Value.ToString())
frm_IMT.Show()
Then When the form loads:
Me.PendingTableAdapter.Fill(Me.Phone_memo_backendDataSet.Tables("Pending"), intPendingID)
