DXSerializer.AllowProperty Attached Event

Allows you to prevent a property from deserialization.

Namespace: DevExpress.Xpf.Core.Serialization

Assembly: DevExpress.Xpf.Core.v21.2.dll

NuGet Package: DevExpress.Wpf.Core

Declaration

See AddAllowPropertyHandler(DependencyObject, AllowPropertyEventHandler) and RemoveAllowPropertyHandler(DependencyObject, AllowPropertyEventHandler).

Remarks

Do the following to prevent a property from being deserialized:

1. Handle the AllowProperty event.
2. Set AllowPropertyEventArgs.Allow property to false.

The following code sample disables the GridControl ID column’s ActualWidthProperty predefined property deserialization:

MainWindow.xaml.cs

using DevExpress.Utils.Serializing;
using DevExpress.Xpf.Core.Serialization;
using DevExpress.Xpf.Grid;
using DevExpress.Xpf.Core;
// ...

public partial class MainWindow : Window {
    public MainWindow() {
        //...
        grid.Columns["ID"].AddHandler(DXSerializer.AllowPropertyEvent, new AllowPropertyEventHandler(OnAllowProperty));
    }

    void OnAllowProperty(object sender, AllowPropertyEventArgs e) {
        if (e.DependencyProperty == GridColumn.ActualWidthProperty)
            e.Allow = false;
    }
}

MainWindow.xaml.vb

Imports DevExpress.Utils.Serializing
Imports DevExpress.Xpf.Core.Serialization
Imports DevExpress.Xpf.Grid
Imports DevExpress.Xpf.Core
'...

Public Partial Class MainWindow
    Inherits Window

    Public Sub New()
        grid.Columns("ID").[AddHandler](DXSerializer.AllowPropertyEvent, New AllowPropertyEventHandler(AddressOf OnAllowProperty))
    End Sub

    Private Sub OnAllowProperty(ByVal sender As Object, ByVal e As AllowPropertyEventArgs)
        If e.DependencyProperty = GridColumn.ActualWidthProperty Then e.Allow = False
    End Sub
End Class
