Adding Mask prevents property change from firing immediately
posted

this seems to be a potential bug.

Earlier I had bound my field like this.

   <igDP:UnboundField Name="Qty"  Binding="{Binding Quantity, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Label="Quantity" />


As soon as I was updating the Quantity field the property changed event was firing. So far so Good.
Now i needed to add a conditional mask to the Quantity field, so i modified my xaml to.
   <igDP:UnboundField Name="Qty"  Binding="{Binding Quantity, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Label="Quantity" >
                                <igDP:UnboundField.Settings>
                                    <igDP:FieldSettings>
                                        <igDP:FieldSettings.EditorStyle>
                                            <Style TargetType='{x:Type igEditors:XamNumericEditor}'>
                                                <Setter Property="Mask" Value="{Binding Path=DataContext.TradeEditorState.QtyMask, 
                                                    RelativeSource = {RelativeSource FindAncestor, AncestorType={x:Type igDP:XamDataGrid}}}"/>
                                                <Setter Property="Background" Value="Transparent" />
                                            Style>                                         igDP:FieldSettings.EditorStyle>                                     igDP:FieldSettings>                                 igDP:UnboundField.Settings>                             igDP:UnboundField>



This caused the immediate property changed event to break, only when i tab out of the Quantity field does the the property change event get fired.
As i am updating the value the property change event does not get fired as it used to fire before.

    Hello Raul,

     

    Thank you for your post!

     

    I have been looking into your issue and I was not able to reproduce it. I have created a small sample application to test this issue. In the sample application I have a simple collection bound to the XamDataGrid. What I can suggest is to use Field instead of UnboundField if the property you are binding to is from the Collection bound to the XamDataGrid. The in my sample application I am setting a Style for the XamNumericInput and I am setting the mask property too.

     

    Would you please modify the sample application attached with the functionality you are using, so it shows the issue. This way I would be able to reproduce it and provide you with further support.

     

    Thank you for the cooperation. Looking forward to hearing from you.
