Display Two Relational Tables In A DataGridView
Jan 1, 2011
I have two tables: One wich contains the columns "first_name", "last_name" and "status_id". The other table contains "status_id" and "description".
Now, I want to display "first_name", "last_name" and "description" in one DataGridView. What is the best way to do this?
What I'm doing now, is that I'm manually adding a datacolumn to the first table. Then I'm looping through each row and filling the new column manually. Now, that doesn't seem very smart and efficient, but I haven't found any better solution.

I am attempting to read an XML and display certain portions of the XML in a datagridview. I was able to get one table at a time, but I am having trouble figuring out how to get ALL the info I want from the XML and not just one table at a time.
I was speaking to someone and they told me that my issue is that the dataset contains datatables and it's not just one big piece of information that I can use. I looked into merge code, but I haven't managed to get anything working the way I would like.[code...]

I've been trying to use lookup tables to display names instead of ID's in a DataGridView using a DataGridComboBoxColumn and have even copied the example shown in the Forms over Data videos produced by Microsoft but still get the following error message:System. =Argument Exception:DataGridView ComboBoxCell value is not valid..Everything was done in the designer and the problem only occurs with the DataGridView; lookups work fine using a combo box when displaying single records.Also the error message only pops up when I close the form. Prior to that all the names are displayed correctly for each record, the drop down list shows the names correctly and I can edit, add and delete rows and save all my edits with no problems. Its just when I close the form that the problem occurs.Each time I press OK in the message box the names in the combo boxes are removed, one by one.

I want to see if anyone has used one table that has a primary key (not displayed) in the DataGridView. Then use a text box on the same form to call and group what if viewed in the DataGridView table. I want to group the displayed data of the DataGridView by the primary key of both tables.

SQL statements:
SQL = "SHOW TABLES;"
Try
conn.Open()
The remarked area works fine when I'm accessing a specific table. I've successfully inserted the products_model field into the combobox too. The datagridview does show the table names in the db using the SHOW TABLES sql statment, but I'm not understanding how to get this info into the combobox instead.

I've read a few threads here but can't seem to get a grip on this. I want to get Vendor data from an access table. And in a datagrid, I want to have a plus sign next to each vendor and when expanded, show the employees of that particular vendor.

I have two relational tables: the Profiles table which contains 3 kinds of user roles (Manager, Developer, Common User) and the Users table which contains information about the user and their roles ID (Profile_ID field) in the Access 2010 database.
I created a Webform in ASP.NET which should simply register users, asking for their names, selecting their roles in a dropdown list and inserting it all in the Access database. As in the following code:
Dim cs As String = ConfigurationManager.ConnectionStrings("Access 2010").ConnectionString
Dim cn As New OleDbConnection(cs)
[Code].....
It happens that I can't insert in the database because they have a relationship between each other, it gives me an error. Actually, I just need to insert data in the Users table 'cause the roles are fixed. How can I do it?
EDIT
The error I get is You can not add or change records, it is necessary that they have a related record in table 'Profiles'.

I'm writing an assignment in VB for a class which displays records from an Access database. It goes as follows:
From a "Rooms" table, I get the rooms to be displayed in a combo box along with 3 checkboxes which will tell me if they have a jacuzzi, private access of a fire place. From a different table in the same database I need to display in text boxes the bed size, weekday and weekend prices for booking each room. The text boxes should display the correct information according to what was selected in the combo box, but I can't get that to work! The checkboxes work fine, but the text boxes stay the same.
Here's what I have so far:
Private Sub Rooms_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Try
Dim RoomsData As New RoomsDataTier
Dim RoomsDataSet As New CottagesDataSet
RoomsDataSet = RoomsData.GetRooms

I am writing a UserControls that display different database tables in textboxes. At present, I change which table the UC looks at by means of a Property that is in byte format and the Set part of the Property calls a subroutine to fix various functions.
Public Property csrCategory() As Byte
Get
Return category
End Get
[code].....
When, say Line 2, is selected the value 2 is passed to the value in the UC.

I have multiple tables that I need to pull and display data from. I have created a new query in the TableAdapter of one table to pull data from related tables based on a parameter. In the Query Designer I can run my query and see all of the columns requested in my SELECT statement, however when I bind this table to a DataGridView and call the new query, it only returns the original columns from Table1.How do I see all of the columns I selected in my query?

I have a datagridview who's datasource is a BindingSource. The problem that I need to resolve is that the DGV has 6 columns, 5 of which come from the same database table, while the other column comes from another database table. Is there anyway of configuring the BindingSource that will make it contain all 6 columns?
The same grid in Part 1 works in the way that when a user selects a row, textboxes and comboboxes are populated with the DGV Row of data in order for the data to be modified. When the user makes any changes, this modified data needs to update the DGV row or BindingSource. How do I associate the changed values back to the BindingSource or the DGV?

I have a database with three tables:
stock
orders
order_details
Stock and Orders are self explanatory. Order_details is a lookup table, holding basically just the orderID, stockID and quantity for each item in the order. That's not very friendly for the user however, so what I want to show is a DataGridView with some elements from order_details, and some from stock, i.e.:
Part_Code, Item_Name, Description, Quantity, Price
I can create a database view for this easily enough, and bind it to a datagridview. It shows existing items in the order fine, but the problem is the view doesn't update when I add new elements to order_details in the dataset. It appears that it's bound to the main database, and so won't update until I save the record. That also has the problem that it's now much harder to update the database. A simple datagridview bound to order_details would make it easy for the user to enter quantities and for me to save the record, this one now needs a custom update statement.
In summary:
- I want to show data from two tables
- I want the datagridview editable (well, the quantity column anyway)
- I want the datagridview to update when I add entries in the dataset
What is the best/easiest way to do this? Is my current approach of a view in the database and custom update statements sensible? How can I get the datagridview to refresh whenever there's a change to the local dataset?

I have 3 related tables in a DataSet - Customers, Products and Orders.I am trying to create an "editable" DataGridView which, ideally, will contain columns from all the tables. I have tried creating the joins in the TableAdapter SQL, but this results in a read-only data grid.
Customers and Orders are joined in a 1:M relationship by CUSTID.
Products and Orders are joined in a 1:M relationship by PRDID.
When the user adds a new Order record they will key the ORDERID, CUSTID, PRDID and QTY.I would like the DataGridView to display the related CUSNAM and PRDDES as soon as the user has keyed the Order record.The data must be displayed on a single data grid row. I am not interested in drill down or multiple data grids.My data looks like this:
Orders: ORDERID, CUSTID, PRDID, QTY
Products: PRDID, PRDDES
Customers: CUSTID, CUSNAM
The data grid should look like this:
ORDERID, CUSTID, CUSDES, PRDID, PRDDES, QTY
My SQL would look like this:
SELECT Orders.ORDERID, Orders.CUSTID, Customers.CUSNAME, Orders.PRDID, Products.PRDDES, Orders.QTY
FROM (ORDERS
INNER JOIN CUSTOMERS ON Orders.CUSTID = Customers.CUSTID)
INNER JOIN PRODUCTS ON Orders.PRDID = Products.PRDID;

this is for VS 2008 w/ an Access database.My database has 3 simple tables, Customer, Services and Workorder.
-Customer table = Customer ID (Customer Name, Address)
-Services table = Service ID(Service type, Cost,)
-Workorder table = Workorder ID(Service ID FK, Customer ID FK, Cost FK, Description, Date)
How I have my database set up is the Workorder table is like a linking table linking all three tables together. This is what I need out of my Windows Form.
-List view 1 contains customers names. Selecting it shows all of the customers previous workorders in the Datagrid view. (This works fine)
-List view 2 contains available services. Selecting it filters the datagrid view that was previously filtered by list view 1(customers). (This I cant figure out)
-In the end the Datagrid view would show all certain records for an individual. You when then be allowed to add the needed information and it would populate the database.All relationships were created to reflect the FKs in the workorder table.What function or coding should I be looking at to accomplish this task?
