Hi Kevin,

I've never worked out how to set a breakpoint on when a value changes like we do in VFP. Any instructions?

For now, I've set a breakpoint in the Entity property's set code. Interestingly, this never runs during the save or when I've changed the date on the screen. Maybe there is something wrong with my binding?

I have the datacontext of the window set like this:

this.DataContext = this.Receipt.DataSet.Tables[this.Receipt.TableName].DefaultView;

and the xaml for this is:

<DatePicker 
Grid.Column="1" 
Grid.Row="1" 
Grid.RowSpan="1" 
Height="25" 
HorizontalAlignment="Left" 
Margin="0" 
Name="dtpRct_Date" 
VerticalAlignment="Center" 
Text="{Binding rct_date, StringFormat=d, Mode=Default}" 
SelectedDateFormat="Short" />

Maybe I should not be referring to this.Receipt.Entity.rct_date but to the the column of the dataset table?

But then again, I have this code in my New Button Click():

        private void btnNew_Click(object sender, RoutedEventArgs e)
        {
            this.IgnoreNavigation = true;

            if (this.grdReceipts.Items.Count == 0)
            {
                this.DataContext = this.Receipt.EntityList;
            }
            this.grdReceipts.SelectedItem = this.Receipt.Entity;
            this.Receipt.Entity.rct_date = lastDate;

            this.IgnoreNavigation = false;
            this.txtRct_Number.Visibility = Visibility.Collapsed;
        }
