Hi,

this is a MM.NET 2010 WPF application.

My clients very rarely delete records so this has never been noticed before. I use a screen that has two pages, one for searching and displaying found records (the records are displayed in a datagrid) and one for editing the details of the selected row in the datagrid.

If I delete a record, the record does get deleted from the backend, but the grid still displays the deleted record until I run a search again.

This is how the DataGrid is defined in the XAML:

						<DataGrid Margin="5" 
                                         x:Name="grdCustomers" 
                                         IsSynchronizedWithCurrentItem="True" 
                                         Grid.Row="8" 
                                         ItemsSource="{Binding Mode=OneWay}" 
                                         SelectionMode="Single" 
                                         GridLinesVisibility="None" 
                                         HeadersVisibility="Column" 
                                         Grid.Column="0" 
                                         AutoGenerateColumns="False" 
                                         Grid.ColumnSpan="3" 
                                         Style="{DynamicResource HDSDataGridStyle}" 
                                         PreviewMouseDoubleClick="grdCustomers_PreviewMouseDoubleClick">
                            <DataGrid.Columns>
                                <DataGridTextColumn Header="Last Name" Width="0.3*" Binding="{Binding cus_lastname, Mode=Default}" IsReadOnly="True"/>
                                <DataGridTextColumn Header="First Name" Width="0.2*" Binding="{Binding cus_firstname, Mode=Default}"  IsReadOnly="True" />
                                <DataGridTextColumn Header="Dept. #" Width="0.2*" Binding="{Binding cus_number, Mode=Default}"  IsReadOnly="True"/>
                                <DataGridTextColumn Header="Company" Width="0.4*" Binding="{Binding cus_company, Mode=Default}"  IsReadOnly="True"/>
                                
                            </DataGrid.Columns>
                        </DataGrid>

My Search button runs this code:

            mmBindingList<CustomerEntity> Customer = this.Customer.SearchCustomers(this.txtLastNameSearch.Text
                                                                                    , this.txtNumberSearch.Text
                                                                                    , selectedArea
                                                                                    , this.txtCompanySearch.Text
                                                                                    , selectedStatus
                                                                                    , selectedBoxType
                                                                                    , selectedRoute
                                                                                    , selectedZipX
                                                                                    , selectedMail
                                                                                    , selectedMiami
                                                                                    , selectedHeathrow
                                                                                    , selectedCredit
                                                                                    , selectedCash
                                                                                    ,selectedHold
                                                                                    , selectedInsurance
                                                                                    , selectedWithEmail
                                                                                    , selectedWithoutEmail
                                                                                    ,selectedCustoms
                                                                                    , selectedServiceFee
                                                                                    , this.txtEmailSearch.Text
                                                                                    );

            this.DataContext = Customer;

The delete button is defined like this:

                            <mmwpf:mmButtonDelete VerticalAlignment="Center" Margin="0,0,0,10" x:Name="btnDelete" />

Any ideas why this could not be working properly?
