Hi everyone,

Is there a way to enable a BindingNavigatorDeleteItem on a BindingNavigator to simultaneously delete a row from the dataset and the underlying data source?

I want to modify the current behavior which involves clicking the BindingNavigatorDeleteItem then clicking the Table1BindingNavigatorSaveItem to make it permanent.

Thanks!

Try This In You BindingNavigatorDeleteItem.Click Event
Try

            If Me.MyDataGridView.Rows.Count < 1 Then
                Exit Sub
            Else
                If Not MyDataGridView.CurrentRow Is Nothing Then
                  
                          Me.Cursor = Cursors.WaitCursor
                            Dim selRow As DataGridViewRow = MyDataGridView.CurrentRow
                            MyDataGridView.Rows.Remove(selRow)
                         Me.Cursor = Cursors.Default
                End if
           End If
 Catch ex As Exception
            MessageBox.Show(ex.Message, "Exception", MessageBoxButtons.OK, MessageBoxIcon.Warning)
            Me.Cursor = Cursors.Default
End Try

Open in new window

Then In Table1BindingNavigatorSaveItem.Click
Try
 Me.Cursor = Cursors.WaitCursor
            If MyDataSet.HasChanges Then
                                Dim ItemDelete() As DataRow = MyDataSet.MyDataTable.Select("", "", DataViewRowState.Deleted)
                                Me.MyTableAdapter.Update(ItemDelete)
                                MessageBox.Show("Done....!!!!(Row deleted)", "Deleted", MessageBoxButtons.OK, MessageBoxIcon.Information)
                                Me.Cursor = Cursors.Default
 Catch ex As Exception
            MessageBox.Show(ex.Message, "Exception", MessageBoxButtons.OK, MessageBoxIcon.Warning)
            Me.Cursor = Cursors.Default
End Try

Open in new window

And something more ...
add also this to your Code to save new and edit data in your Database
 Dim ItemInsert() As DataRow = MyDataSet.MyDataTable.Select("", "", DataViewRowState.Added Or DataViewRowState.ModifiedCurrent)
 Me.MyTableAdapter.Update(ItemInsert)

Open in new window

Hope that Helps

Copy the Update call from your save method to delete method.
