how can i detect if changes have been made to my dataset
hi , i have a form with a datagrid, which is bound to a dataview, i want to write a procedure when the form_closing
event happens.
if there are any changes made to the dataset (the datagrid bound dataset /dataview)
then notify the user.
how can i detect this, any sample links?
i did try the microsoft concurrency link

Hi jxharding,
Why are they to late ?
Why are they to late ?
maybe look at this code
Private Sub Form1_Closing(sender As Object, e As System.ComponentModel.Canc
' Determine if text has changed in the textbox by comparing to original text.
If textBox1.Text <> strMyOriginalText Then
' Display a MsgBox asking the user to save changes or abort.
If MessageBox.Show("Do you want to save changes to your text?", "My Application", MessageBoxButtons.YesNo) = DialogResult.Yes Then
' Cancel the Closing event from closing the form.
e.Cancel = True
End If ' Call method to save file...
End If
End Sub 'Form1_Closing
End Class 'Form1
Private Sub Form1_Closing(sender As Object, e As System.ComponentModel.Canc
' Determine if text has changed in the textbox by comparing to original text.
If textBox1.Text <> strMyOriginalText Then
' Display a MsgBox asking the user to save changes or abort.
If MessageBox.Show("Do you want to save changes to your text?", "My Application", MessageBoxButtons.YesNo) = DialogResult.Yes Then
' Cancel the Closing event from closing the form.
e.Cancel = True
End If ' Call method to save file...
End If
End Sub 'Form1_Closing
End Class 'Form1

the plan up to right now was to execute this little piece of code,
If Ds1.HasChanges = True Then
MessageBox.Show("Update!")
Exit Sub
End If
and this would (supposed to have) allow the user to return to the form.
but now that you mention it, i prob should just put a dialogbox with a Yes and No button, asking the user if he wants to save.
