Records Do Not Show Using DataGridView?
Jul 13, 2010
Why do I cannot show my records using datagridview? The database I use is sql server 2005 with the extension of ".mdf". Also if I use the wizard to add the data source. I can add,delete records and show but when I change the startup form and run the form that connection is code to display. It doesn't show the records.
Below here is my code :
Imports System.Data.SqlClient
Public Class Form2
Dim con As New SqlConnection
Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code] .....

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.

If Not (rs.BOF Or rs.EOF) = True Then
txtSNO = rs(0) & ""

I have a dataset called KeyData made up of two tables Customers and Orders.
I have two forms, one named MainForm that shows records from Customers in details view and the related Orders shown in GridView called OrdersDataGridView. The other form is called OrdersForm and is populated with the Orders table from the keydata dataset and shows records in details view.
When I navigate the MainForm customer records the correct orders are shown in the OrdersDataGridView. So far so good.
Here's the code that was generated when I dropped the tables within KeyData dataset onto the MainForm:
Private Sub MainForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'KeyData.Orders' table. You can move, or remove it, as needed.

I have two problems with my datagridview in VB 2005 that I did not encounter in VB6. I would like to add multiple records to a datagridview by allowing the user to tab and type.When they get to the end of a record and tab it should go to the next record like Access does. The user can move to the next record and it even shows the pencil on the left leading them to believe that a new record is being created. But, it will not create the record unless they first click on my button that will add the record with the code BindingSource2.AddNew(). I use a bindingsource to populate the datagridview. Here are some snipits of my code for clarity:
DataGrid2.DataSource = BindingSource2
GetDataDetail(
"Select * from [Order Detail] Where [Order Detail ID] = Null")

I have a datagridview on my form which is not bounded to any database table.The datagridview is only used for data entry. When the user has populated the datagridview and click the save button, I want to be able to save all the rows into a table in my database.At the moment, if more than one row is populated, my code is saving only the second row of the datagridview and everything else is ignored. If only one row is populated, it works fine.I am using Oracle database 11g and a store procedure to insert the records. Below is my code.
Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
Dim cmd As New OracleCommand("MHMS_Package.Insert_Service", conn)
Dim strCmd As New OracleCommand("MHMS_Package.Insert_Service_Details", conn)[code].....

I have a DataGridView control that is bound to a dataset that I set up in design mode. This grid will contain addresses for a client. The relationship is 1 client to many addresses. So, when the user selects a client, I wish for this grid to populate with only the address records for that client. How do I set up in code a way for the grid to recognize this?
