I have a WPF DataGrid that I am filling using
var allLines = from Lines in ctx.InvoiceLines join PerPs in ctx.ProductsViews on Lines.ProductCode equals PerPs.ProductCode
where (Lines.BranchNo == BrNo) && (Lines.Docket == Docket)
select new { Lines.ProductCode, Lines.Description, Lines.Inv_Quantity, Lines.Grn_Quantity,
Lines.Inv_Price,Lines.Grn_Price,Lines.Inv_Total, Lines.Grn_Total, Lines.AnalCode,
Lines.Vat_Rate, Lines.GrnNo,Lines.Comment , PerPs.OuterUnits};
dgGrid.ItemsSource = allLines;
I want to use two way binding to update the database when any of the values are changed or when a new row is added. Is that possible?
My xaml code is
<DataGrid Grid.Row="3" x:Name="dgGrid" DataContext="{Binding}" FontSize="16" HorizontalScrollBarVisibility="Visible"
VerticalScrollBarVisibility="Visible" SelectionUnit="FullRow" SelectionMode="Extended" AutoGenerateColumns="False"
SelectionChanged="dgGrid_SelectionChanged" >
<DataGrid.Columns>
<DataGridTextColumn Width="Auto" Header="ProductCode" Binding="{Binding ProductCode, Mode=TwoWay, Path=IsSelected, UpdateSourceTrigger=PropertyChanged}"/>
<DataGridTextColumn Width="250" Header="Description" Binding="{Binding Description, Mode=TwoWay, Path=IsSelected, UpdateSourceTrigger=PropertyChanged}" FontSize="14"/>
<DataGridTextColumn Width="61" Header="Inv_Quantity" Binding="{Binding Inv_Quantity, Mode=TwoWay, Path=IsSelected, UpdateSourceTrigger=PropertyChanged}"/>
<DataGridTextColumn Width="63" Header="Grn_Quantity" Binding="{Binding Grn_Quantity, Mode=TwoWay, Path=IsSelected, UpdateSourceTrigger=PropertyChanged}"/>
<DataGridTextColumn Width="59" Header="Inv_Price" Binding="{Binding Inv_Price, Mode=TwoWay, Path=IsSelected, UpdateSourceTrigger=PropertyChanged}"/>
<DataGridTextColumn Width="61" Header="Ord_Price" Binding="{Binding Grn_Price, Mode=TwoWay, Path=IsSelected, UpdateSourceTrigger=PropertyChanged}"/>
<DataGridTextColumn Width="72" Header="Inv_Total" Binding="{Binding Inv_Total, Converter={StaticResource Currency}, Mode=TwoWay, Path=IsSelected, UpdateSourceTrigger=PropertyChanged}"/>
<DataGridTextColumn Width="74" Header="Grn_Total" Binding="{Binding Grn_Total, Converter={StaticResource Currency}, Mode=TwoWay, Path=IsSelected, UpdateSourceTrigger=PropertyChanged}"/>
<DataGridTextColumn Width="58" Header="AnalCode" Binding="{Binding AnalCode, Mode=TwoWay, Path=IsSelected, UpdateSourceTrigger=PropertyChanged}"/>
<DataGridTextColumn Width="40" Header="Vat_Rate" Binding="{Binding Vat_Rate, Mode=TwoWay, Path=IsSelected, UpdateSourceTrigger=PropertyChanged}"/>
<DataGridTextColumn Width="Auto" Header="GrnNo" Binding="{Binding GrnNo, Mode=TwoWay, Path=IsSelected, UpdateSourceTrigger=PropertyChanged}"/>
<DataGridTextColumn Width="Auto" Header="Comment" Binding="{Binding Comment, Mode=TwoWay, Path=IsSelected, UpdateSourceTrigger=PropertyChanged}"/>
<DataGridTextColumn Width="Auto" Header="PerP" Binding="{Binding OuterUnits}" IsReadOnly="True"/>
</DataGrid.Columns>
<DataGrid.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="LightSteelBlue"/>
</DataGrid.Resources>
</DataGrid>
When I run this code all but the PerP column is empty.
I'm quite lost as to how to do the best way so any help will be very much appreciated.
