Vb net datagridview cellvalidating change value

NET 2005 2.0 Framework application is using a Data Grid View for SQL data access and user data entry.

As part of exception/error handling, the app wants to advise the user when he/she enters a value into a DGV field that is inappropriate; for example, an alpha character in a cell containing an integer value.

When the user types in the alpha and hits enter, Begin Edit fires off, realizes the cell is dirty, and can see the previous/old cell . Data Error then promptly frags the entry (interdicting Cell Value Changed execution), but again can't say what value/ character(s) the user entered that were inappropriate.

Since the entered characters persist on the DGV (until . End Edit are called), they must be somehow accessible; can anyone explain how to grab them? Hey Roach, If you handle validation on a cellular level you can access the formatted value or cancel the validation and value being changed at all...

look into the Data Grid View Cell Validating Event Args and the Cell Validating() method of the DGV: Brendon "Roach" VB.

Cancel = True else 'here I was thinking on something like Data Grid View Text Box Column7.value = 60 and so on, but none of this works. I am desperate for solution and here are my coding: Private Sub btn Fill DGVWith Excel_Click(By Val sender As System. Event Args) Handles btn Fill DGVWith Exce.click Dim obj Excel As New Excel.

End If End If Dias_Asueto Then Msg Box("Los dias correspondientes son " & Dias_Asueto) e.

Visible = True Dim bol Flag As Boolean = True Dim excel Row As Integer = 7 Dim DGVRow As Integer = 1 Try Do While bol Flag = True If Convert. Cells(excel Row, 1).value) = "" Then bol Flag = False Exit Do End If With Data Grid View1 Data Grid View1.

Cells(excel Row, 9).value End With Loop Catch ex As Exception Message Box.
