Working with a data grind in visual studio-Visual Basic 2008 with an SQL 2008 database.

                 Here’s the deal. This is a VB 2008 Windows Application project with an SQL 2008 database, and I am comparing what I can do with a “data grid view”, with what I can do in a “details view” from the data sources.
                  When I use the details view, I notice that the cells are actually text boxes which gives me access to their contents programmatically speaking. I could code in a multiplication function like

Dim Result_A As Integer
Result_A  =  textbox_A.Text * 110
Label_A = Result_A

                   Is there a way for me to get access to the contents of the cells in a row (record) if the view is a Data Grid View, and write functions similar to those in the Details view?

Yes.  Here is an example I have used that allows me to retrieve the contents of a particular DGV cell:


    Private Sub dgvMembers_and_Guests_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles dgvMembers_and_Guests.Click
        'First test for rows present then select the appropriate tab on the form based on the Membership Type
        If dgvMembers_and_Guests.RowCount > 0 Then
            mKey = Trim(dgvMembers_and_Guests.CurrentRow.Cells(0).Value)
            mMember_Type = Trim(dgvMembers_and_Guests.CurrentRow.Cells(1).Value)
            srFill_Screen()
        Else
            mKey = ""
            mMember_Type = ""
            srClear_Screen()
        End If

        btnExit.Focus()
    End Sub


This returns the values of the first and second cells on the current row that the user clicks in the Data Grid View.

EYoung,
      Just wanted to let you know that I am working on this. So far I replaced your dgv name with mine, and I had ti declare mine.  I added:
Dim dgvCreditorAccounts As New dgvCreditorAccounts
Now I have to some how define dgvCreditorAccounts  I admit I am not a pro and I have to research things every now and then.

EYoung,
I am working with Dollars & Cents which means I need the Decimal data type. RowCount is not a member of Decimal. There probably is a way of getting around this though.

Now sure why you want to use a RowCount as a member of Decimal.  I only use RowCount to confirm that there are rows in the DGV.

You can define a memory variable as a decimal, i.e.
Dim mDecimal_Value As Decimal

Then:
mDecimal_Value = Trim(dgvCreditorAccounts.CurrentRow.Cells(0).Value)

EYoung,
 
As a way of declaring and defining I wrote:
Dim dgvCreditorAccounts As Decimal
If dgvCreditorAccounts .RowCount > 0 Then                  < problem on this line [Rowcount is not a member of Decimal]
Is there another type that will allow 2 decimal places to the right of the decimal point? The data will be money.

Are you trying to define your DataGridView control as a decimal value?  If yes, you can't do that.  You need to define the DGV as a DGV and the variable separately as a decimal.  That is why the RowCount is not a member.
