xammaskededitor null string
posted

I am using a xammaskededitor in a grid. When the user deletes all the chars in a cell the grid sets my string/property to null. Is there a way to have the grid set it to string.empty or "" so I don't have to check for null in my property accessor.

 

        <Style x:Key="PhoneNumberStyle" TargetType="{x:Type igEditors:XamMaskedEditor}">
            <Setter Property="Mask" Value="{}{char:20:A-D0-9#*,}" />
        </Style>

 

                        <igDP:Field Name="Phone" Label="Phone">
                            <igDP:Field.Settings >
                                <igDP:FieldSettings LabelWidth="90" EditAsType="{x:Type sys:String}" EditorStyle="{StaticResource PhoneNumberStyle}">
                                </igDP:FieldSettings>
                            </igDP:Field.Settings>
                        </igDP:Field>

    Hello,

    I believe there is no such property exposed that allows this. What you can do is to set the ValueConstraing of the editor so that no null values are allowed.

               Style s = new Style(typeof(XamMaskedEditor));

                ValueConstraint constraint = new ValueConstraint();

                constraint.Nullable = false;

                s.Setters.Add(new Setter(XamMaskedEditor.ValueConstraintProperty, constraint));

                xamDataGrid1.FieldLayout.Fields["X"].Settings.EditorStyle = s;
