Mapping column in currow of datagrid

I have a datagrid where I have successfully been able to get the current row number to match the selected row. I can also delete a row by an ID number.

What I need to do is match the ID number to the ID number in the currow so I can delete it with my Delete From Statement.

Here is my code so far. What do I need to do?

VB Code:

Dim curRow As Integer
curRow = DataGrid1.CurrentRowIndex
MsgBox(curRow)
 
Dim strDataBaseName As String = "C:\path\dbname.mdb"
Dim cnn As New OleDb.OleDbConnection( _
    "Provider=Microsoft.Jet.OLEDB.4.0;" & _
        "Data Source=" & strDataBaseName)
Dim cmd As New OleDb.OleDbCommand
cnn.Open()
cmd.Connection = cnn
Try
    cmd.CommandText = "Delete From TimeGr Where ID = " & 33 ' map this
        ' to the ID in the current row instead of having it hardwired in
        ' the code.
        cmd.ExecuteNonQuery()
Catch exError As Exception
        MessageBox.Show(exError.Message)
End Try

Imagine the ID column in your grid is the first column for example, then:

VB Code:

Dim ID as Integer
ID=Datagrid1.Item(DataGrid1.CurrentRowIndex,0)

Thank you Lunatic3 that did the trick :D One more question. Is there a built in command to refresh the datagrid after the delete to relect the change?

I am Googling it now but wanted the question out there just in case I don't find anything.

Thanks again!

To refresh the data in datagridgrid you have to refresh the underlying datasource. There is a Refresh method in the Datagrid (available for generic control object) that just refreshes the control, i.e invalidates and repaints it. So Don't confuse these two.

Ok I am lost. It would seem that I need to reload the Datagrid but so far I have not been able to accomplish that while the form is open. The only way I can get the changes to show is to close the form and reopen.

Here is the code but I can't figure out how to refresh the adapter. Requesting a refill does nothing because, my guess, is that it is not hitting the database the second time. It is using the data from memory. Do I need to create a second dataset?

VB Code:

Private Sub Button1_Click(ByVal sender As System.Object, _
        ByVal e As System.EventArgs) Handles Button1.Click
 
        'This fills the data adapter the first time.
        OleDbDataAdapter1.Fill(DsPayroll1)
 
    End Sub
 
    Private Sub cmdDeleteLine_Click(ByVal sender As System.Object, _
        ByVal e As System.EventArgs) Handles cmdDeleteLine.Click
 
        Dim strDataBaseName As String = "c:\path\dbname.mdb"
        Dim cnn As New OleDb.OleDbConnection( _
            "Provider=Microsoft.Jet.OLEDB.4.0;" & _
            "Data Source=" & strDataBaseName)
        Dim cmd As New OleDb.OleDbCommand
        Dim getID As Integer
 
        getID = DataGrid1.Item(DataGrid1.CurrentRowIndex, 21)
        MsgBox("Rec # " & getID & " has been deleted.", _
            MsgBoxStyle.OKOnly, "Record Deleted")
 
        cnn.Open()
        cmd.Connection = cnn
        Try
            cmd.CommandText = "Delete From TimeGr Where ID = " & getID
            cmd.ExecuteNonQuery()
        Catch exError As Exception
            MessageBox.Show(exError.Message)
        End Try
        cnn.Close()
 
        ' This should refill the data adapter but so
        ' far it has not worked at all.
        OleDbDataAdapter1.Fill(DsPayroll1)
 
    End Sub
