Here is how we can achieve this in XAML:

Define style in the resources:

<Style x:Key="xamDateTimeEditorStyle" TargetType="{x:Type igEditors:XamDateTimeEditor}">
            <Setter Property="ValueConstraint">
                <Setter.Value>
                    <igEditors:ValueConstraint MinInclusive="{x:Static sys:DateTime.Now}" />
                </Setter.Value>
            </Setter>
</Style>

And here is how you setup your DataGrid:

<infraDp:XamDataGrid Name="DetailsViewModelXamGrid"
                                    HorizontalAlignment="Stretch"
                                    HorizontalContentAlignment="Stretch"
                                    ScrollViewer.VerticalScrollBarVisibility="Auto"
                                    AutoFit="True" DataSource="{Binding DetailsVieModel}">

I hope this will help, thanks! ~ Shams

Ranjith,

Here is how to create a style and assign it.

Style style = new Style(typeof(XamDateTimeEditor));

            ValueConstraint v = new ValueConstraint();

            v.MinInclusive = DateTime.Now;

            v.ValidateAsType = ValidateAsType.DateTime;

            style.Setters.Add(new Setter(XamDateTimeEditor.ValueConstraintProperty,v));

            xamDataGrid1.FieldLayouts[0].Fields[0].Settings.EditorStyle = style;

For events, you can try something like this:

void xamDataGrid1_EditModeEnded(object sender, Infragistics.Windows.DataPresenter.Events.EditModeEndedEventArgs e)

        {

            if (((DateTime)e.Editor.Value).Day < DateTime.Now.Day)

            {

            }

        }

Hello Alex,

     Can you give me an example code snippet of how to use ValuConstraing property for date validation scenario as mentioned above? I have successfully implemented it for regex and others but not for date. Appreciate you help in advance.

Thanks,

Ranjith
