I have a datagrid that fills from a load button then  we will scan a barcode label in the first column of the datagrid i want it to validate that value against DSBC1 dataset to see if it is valid. how do i get the current cell value and validate that value.


here is my load code for the datagrid.
  Private Sub LoadBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LoadBtn.Click
        Me.SqlSelectCommand1.Parameters("@Cuttxt").Value = Me.CutIdtxt.Text
        Me.lblmarker.DataBindings.Clear()
        Me.lblmarker.DataBindings.Add(New System.Windows.Forms.Binding("Text", Me.CutDetailsDS1, "VwCutTicketDetails.Actual Marker"))
        Me.SqlSelectCommand2.Parameters("@Cuttxt").Value = Me.CutIdtxt.Text
        Me.ScrapDS1.ScrapTable.Columns("CutID").DefaultValue = Me.CutIdtxt.Text
        Me.SqlDataAdapter1.Fill(Me.ScrapDS1)
       
 
        Me.SqlDataAdapter2.Fill(Me.CutDetailsDS1)
        Me.ScrapDS1.ScrapTable.Columns("Item").DefaultValue = Me.lblfab.Text
        Me.lblfab.ForeColor = System.Drawing.Color.Red
        If Me.lblmarker.Text = Me.ToString.Empty Then
            Me.lblmarker.DataBindings.Clear()
            Me.lblmarker.DataBindings.Add(New System.Windows.Forms.Binding("Text", Me.CutDetailsDS1, "VwCutTicketDetails.Marker"))
        End If
 
        Me.DataGrid1.Focus()
 
    End Sub

When do you want to validate? At what event? Would it be selected row only or for the whole data grid?

I do not understand your code fully but here is an example. I hope you can modify it according to your requirements.

btnValidate.Press:

if grid1.Selectedrows.count = 1 Then
   DSBC1.tables(0).defaultview.rowfilter = "ClientID=" & grid1.SelectedRows(0).Cells(0).Value
   if DSBC1.Tables(0).DefaultView.Count > 0 then
      'The ClientID exists
   Else
      'The ClientID does not exist
   End if
   DSBC1.Tables(0).DefaultView.RowFilter = ""
End If

Try this then

if grid1.CurrentRowIndex >= 0 Then
   DSBC1.tables(0).defaultview.rowfilter = "ClientID=" & grid1.Item(Grid1.CurrentRowIndex, 0)
   if DSBC1.Tables(0).DefaultView.Count > 0 then
      'The ClientID exists
   Else
      'The ClientID does not exist
   End if
   DSBC1.Tables(0).DefaultView.RowFilter = ""
End If
