If you select the containing object into a PropertyGrid, you'll get a property that uses the color editor drop-down. Take a property of type Color for instance. What I'm trying to do is force the use of the custom editor, and not allowing for the property to be editted textually in the property grid. You can't use the direct text edit method, nor will the buttons for a custom editor (Modal or DropDown) be shown. In general, when you apply the ReadOnly attribute to a property, that entire entry in the PropertyGrid is disabled (as expected). But I'm trying to get some very specific behavior out of the PropertyGrid. Public Class DefaultPropertyGridItemElementīack to the control, let’s subscribe to the RadPropertyGrid.The editor is working just fine Bob. Public Overrides Function IsCompatible(data As PropertyGridItemBase, context As Object) As Boolean Protected Overrides ReadOnly Property ThemeEffectiveType() As Type ![]() Return New CustomPropertyGridValueElement() Protected Overrides Function CreatePropertyGridValueElement() As PropertyGridValueElement Public class DefaultPropertyGridItemElement : PropertyGridItemElement Public override bool IsCompatible(PropertyGridItemBase data, object context) Protected override Type ThemeEffectiveType Return new CustomPropertyGridValueElement() Protected override PropertyGridValueElement CreatePropertyGridValueElement() Public class CustomItemElement : PropertyGridItemElement In addition, it is necessary to create another PropertyGridItemElement which is not compatible with your custom item: Custom PropertyGridItemElements IsCompatible method and control whether the custom element is applicable for the specific PropertyGridItem. In order to avoid reusing of the custom element for other items, you can override the PropertyGridItemElement. To put this value element in action, we will create a descendant of PropertyGridItemElement, and we will override its CreatePropertyGridValueElement method. Thenįor Each rb As RadRadioButtonElement In stackPanel.Children If item IsNot Nothing AndAlso rb.Text item.FormattedValue AndAlso rb.ToggleState = ToggleState. Private Sub rb_ToggleStateChanged(sender As Object, args As StateChangedEventArgs)ĭim rb As RadRadioButtonElement = Tr圜ast(sender, RadRadioButtonElement)ĭim item As PropertyGridItem = Tr圜ast(Me.VisualItem.Data, PropertyGridItem) GetValues(GetType(DeliveryType))ĪddHandler rb.ToggleStateChanged, AddressOf rb_ToggleStateChanged StackPanel.Orientation = Orientation.Verticalįor Each enumItem As Object In.

Next, we should create a custom PropertyGridValueElement which is purposed to be used in a derived PropertyGridItemElement.
