Scrolling a Disabled Listbox in WPF
Table of Contents
Recently I had a requirement when developing an application,where i needed a listbox which was to be disabled but yet can be scrolled,so that all the contents in it was visible.Applying the property,IsEnabled=False makes the whole listbox disabled even disabling the scroll. I just found out a way around this.I created a custom listbox(MyScrollableListbox) with a property IsItemsEnabled.Setting this property to true,gives the normal listbox behaviour.When set to false only the ItemsPresenter of the listbox is disabled,so that scrolling is possible
The Custom Listbox looks like this(just one property added for now)
Public Class MyScrollableListbox Inherits ListBox Public Property IsItemsEnabled() As Boolean Get Return GetValue(IsItemsEnabledProperty) End Get Set(ByVal value As Boolean) SetValue(IsItemsEnabledProperty, value) End Set End Property Public Shared ReadOnly IsItemsEnabledProperty As DependencyProperty = _ DependencyProperty.Register("IsItemsEnabled", _ GetType(Boolean), GetType(MyScrollableListbox), _ New FrameworkPropertyMetadata(Nothing)) End Class
In the xaml(or if you are going to make it a custom control then you can give it in your Generic.xaml)
Now if you set the property IsItemsEnabled to false the listbox will be disabled,but allowing you to scroll.

Hope it helps :)
