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 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.

Another question. . I pull this infor from a view via tableadapter and it comes from several different tables.. How could I save my changes and insert the new records to the appropriate tables>?
What I am trying to do is update existing records in a dataset with an unbound datagridview. It updates just fine but I have added a simple backcolor change for errors. What I don't understand is it will update fine but throw the backcolor = red at the same time. Am I overlooking something here?

I'm trying to get this working in a test application before adding it to my main project, so that's why the names of controls are the way they are.The errors I'm trying to show are if "Inventory ID", "Cart" and "Shelf" do not match. When they don't match it doesn't update, which is what it is supposed to do. However, if they do match they update just fine but also show the Inventory ID error. If I comment out that ElseIf for the Inventory, it throws the Cart error. It's like the ElseIf blocks get called even if the If statement is true...
I created a database (.mdf) file. I added data to it after running the program in debug mode. When I closed it and opened it up again, the data I got was stored and loaded again.I closed my whole Visual Basic Express program. When I opened it up again, all the data had disappeared.
Can you tell me what I am doing wrong with the program? I can't get queries to work either. It worked when I used the NOrthwind dataset this past weekend but it is not working when I use my own or empty dataset.
I have a graphics application I'm working on that displays full screen so there's no control in the upper right to close the application. I have it set up so that a right click closes the application but I noticed that a right click menu comes up on the desk top after my application closes which is no big deal. You could ignore it but I was wondering if there's a way to turn off the right click menu so that it wouldn't come up though I would want it to be enabled after that first click that closes my program.
So the right click would close the program disable the right click menu and then enable it again so that the next right click would show the menu. Haven't come up with anything on searches. I could use something else to close my application but if there's a convenient way of doing this I would like to find out what it is. I have almost every key on the keyboard doing something though I haven't used F1 through F12 at the top of the keyboard. Maybe I'll use F1 if I don't find out how to do this. How to use F1 to F12 to close or do something?
I've been using keypress events to do a lot in my application but for
Select Case e.KeyChar
Case "F1"c
isn't valid.
I tried other things. {F1} etc. I have option strict on. Thus the little c is necessary for characters like "a"c or "b"c.
I managed to displayed records from two tables in one datagridview and the first column being a combobox. Now, I would like to get those records displayed and save it to another table. this what I did.
For i As Integer = 0 To dtgLoad.Rows.Count - 1

"VALUES (@Teacher, @Subject)", cnn)
With command.Parameters

I would like to loop through the records of the datagridview and then save the same to a table.
I need to use a virtual drive (ram disk) to save data temporarily. Which ram disk program is good to use.
View 6 RepliesI am having a problem trying to save records in a parent / child data relation. I have to tables tblContacts & tblMember. There is a fk relation on the ContactID field. The tblContacts table is the master record. I am using a set up bound windows forms controls to do the data collection. The problem that I am having is in saving the child record. After the form is populated in both the fields and hitting the save button the items in the child record get deleted. It does add a row in the child record but only the ContactID (from the master table) and the key for the tblMember table. This program will not be using a datagrid. I did experiment with datagrids and it works well. The problem is when I try to use detail views in the form of textboxes that are bound to the bindingsource.

I can see that since the new master record incites the addition of a new row, the data is abandoned. Once there is a save done to the master / child record I can go back and modify the fields and it saves it successfully. I know I must be missing something small. I am not sure how to work around this so that the controls are read into memory and then completed in the new row. I have an example of my code:

My client recently got this error but I can't reproduce it on my pc. Any Idea what the problem could be. I have a master/detail scenario. So I have a grandparent/parent relationship, so when I select a product from my product combobox it displays the relevant results from the Result_Header table in my first datagridview.
Then I have a parent/child relationship so that when I select a result_header item from my first datagridview it displays the child records from the Result_detail table. If i'm adding a new Result_Header and then click save, I search for existing tests for the chosen product and insert them as new datarows into the Result_detail table. then I can update the child rows and click the second save button and it saves what I edit. Quite complicated.

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).
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 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 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'.
