You normally wouldn't care about the row index in the DGV. What are you trying to do with it?

Hi Dave
thanks for your reply.
basically my DGV has only a few bound columns and what i intend to do is retrieve further data from table based on the select DGV row.
so if rowindex 0 is selected from the grid i want to be able to talk to the table based on the same index making sure its the same record. i dont want to add more bound columns in the grid because there are too much.
any tips or advice would be appreciated.
Robby

OK. Then you're looking for the SelectedRows or SelectedCells. They return a DataGridViewRow and DataGridViewCell respectively. These will contain the data that the user clicked on, regardless if the DGV is bound or not, sorted or not.
Private Sub DGV1_SelectionChanged(blah, blah) Handles DGV1.SelectionChanged
For Each row As DataGridViewRow In DGV1.SelectedRows
For Each cell As DataGridViewCell In row.Cells
Debug.Write(cell.FormattedValue.ToString() & " | ")
Next
Debug.WriteLine(String.Empty)
Next
End Sub
Each DataGridViewCell object knows which DataGridViewRow contains it, through its OwningRow property. If the user clicks on any cell, the OwningRow property of that cell will give you the DataGridViewRow that the user clicked in. Using that, you can get the ID column of the row and use that value any way you want.
For Each cell As DataGridViewCell In DGV1.SelectedSells
Debug.WriteLine(String.Format("Cell Data: {0} Parent Row ID: {1}", _
cell.FormattedValue.ToString, _
cell.OwningRow.Cells("IDColumnName").FormattedValue.ToString))
Next

Thank for your patience dave.
I just need clarification on something.. realisticly what im trying to do is clone a record and rewrite columns so that essentially its not a duplicated record after all when its written to a table but I havent been able to work that out. (any advice you can give me will save you reading below and helping me along where im at right now)..
so imagine in my DGV i have surname , firstname , address . if i select a particular record showing these columns and rows respectively i want to additionally go to the table and also get "phone number" etc.
i guess what im asking is based on the DGV selection how can i go to the table and pickout the rest of the fields i need for that same row of data selected in the DGV.
e.g. SELECTED ROW IN DGV(IN BOLD)
[SURNAME]-[FIRSTNAME]-[ADDRESS]
CHAN,...........ALEX,.......mamre drive.............[AT INDEX 0}
Bloggs,.......JOE,.......2 Hollywood st , hollywood..INDEX 1
if i sort this by FIRSTNAME IN DESCENDING. it would be
[SURNAME]-[FIRSTNAME]-[ADDRESS]
Bloggs,.........JOE,.....2 Hollywood st , hollywood... INDEX 0
CHAN,.............ALEX,.....mamre drive .....................INDEX 1
im trying to use the below line
where "i" is the row number coming from DGV select row index.
dim value as string
value = ds.tables("customers").rows(i).item("phone")
* if i use the index from the DGV after i sort it it doesnt return the correct record to match the phone number...
just a reminder.. If i dont sort the DGV at all. I can use the DGV.index and use it here :
dim value as string
value = ds.tables("customers").rows(i).item("phone") it WORKS CORRECTLY. its just after i sort the DGV that I cant get
ds.tables("customers").rows(i).item("phone") to return the correct row from the table..
sorry about this dave .. thanks for your patience.

You do not need the row number at all. Once you have to DataGridViewRow, you have the ENTIRE record that was clicked on. Every field that the grid was bound to in is that row object. So
Dim phone as String = cell.OwningRow.Cells("phone").Value
gives you the Phone column of the row that was clicked on. The example, of course, assumes that the Value property in that column returns a String. You'll have to change it to match whatever you're expecting.
You don't need to go to the table to get the rest of the fields.

If you didn't retrieve all the data you wanted in the first fetch, you need to change the first fetch to include the primary key in the table you bound the DGV to. When the use clicks on a row, you grab the PK value from the DataRow object and use that value in a second request to get the columns you need specifying the PK in the WHERE clause of the SQL SELECT.

You're getting this error message because your trying to add a reference to a .DLL that is not COM-based, just like the message says.
In order to use the functions in that .DLL, you do NOT add a reference to it. You call the functions through P/Invoke. Define the function headers in your code using the Declare statement and setting up the arguments that the function is expecting. For example, to call the Win32 Beep function found in kernel32.dll:
Declare Function Beep Lib "kernel32.dll" (ByVal frequency As Integer, ByVal duration As Integer) As Boolean
Then later in your code:
Dim r As Boolean
' Make a sound at 4000Hz, for 250 millisecond (1/4 second)
r = Beep(4000, 250)

First of all, txt speak just makes you look like an idiot
Second of all, we're here to help people trying to program. People who say 'I don't know anything, so tell me from scratch how to do these tasks', don't get much help.
Third, VB6 is a dead language, and a terrible one. Microsoft withdrew all support some time ago, why would you learn this intead of VB.NET ?

I am trying to help, seriously. Your question is just annoying, because of how you typed it. others will tell you the same, or just ignore you. We're not 12 years old here.
And, VB6 *is* a dead language. Why are you learning it ? I suspect it's a class, in which case, you really need to do your own homework.
