dependency-properties

I have a UserControl which contains a listbox and few buttons. <UserControl x:Class="ItemControls.ListBoxControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"> <Grid> <ListBox:ExtendedListBox SelectionMode="Single" ItemsSource="{Binding LBItems}" Height="184"> <ListBox.ItemTemplate> <DataTemplate> <CheckBox Content="{Binding}"/> </DataTemplate> </ListBox.ItemTemplate> </ListBox> <Button

I have a DependencyObject with a DependencyProperty: public class DependencyObjectClass: DependencyObject { public static DependencyProperty BooleanValueProperty = DependencyProperty.Register("BooleanValue", typeof (bool), typeof (DependencyObjectClass)); public bool BooleanValue { get { return (bool)GetValue(BooleanValueProperty); } set { SetValue(BooleanValueProperty, value); } } } I also have my data source class: public class DataSource: INotifyPropertyChanged { private bool _istrue; public bool IsTrue { get { return _istrue; } set { _istrue = value; if (PropertyChanged != null)

I'm creating an Image.Source - String binding in code like: var newBinding = new System.Windows.Data.Binding() { Path = new PropertyPath("MyImageUrl") }; BindingOperations.SetBinding(attachedObject, Image.SourceProperty, newBinding); This approach works well for, for example, TextBlock.TextProperty - String bindings, but for the Image.Source - String I ideally would like the Binding to automatically insert a conversion for me - in the same way that the Xaml binding does when I use: <Image Source="{Binding ImageUrl}" /> I realise I can add my own converter to mimic the Xaml binding behaviour,

I have an extremely simple IMultiValueConverter that simply OR's two values. In the example below, I want to invert the first value using an equally simple boolean inverter. <MultiBinding Converter="{StaticResource multiBoolToVis}"> <Binding Path="ConditionA" Converter="{StaticResource boolInverter}"/> <Binding Path="ConditionB"/> </MultiBinding> and the inverter: public class BoolInverterConverter : IValueConverter { #region IValueConverter Members public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { if (value is bool) { return !(

I try to use enum type as a dependency property in my custom control, but always get an error: public enum PriceCategories { First = 1, Second = 2, Third = 3, Fourth = 4, Fifth = 5, Sixth = 6 } public static readonly DependencyProperty PriceCatProperty = DependencyProperty.Register("PriceCat", typeof(PriceCategories), typeof(CustControl), new PropertyMetadata(PriceCategories.First)); }; public PriceCategories PriceCat // here I get an error "Expected class, delegate, enum, interface or struct" { get { return (PriceCategories)GetValue(PriceCatProperty); } set { SetValue(PriceCatProperty, value)

I would like to arrange items of a collection in a grid with a specific number of columns and rows (say 4x6). Each item exposes the dependency properties (integer) X and Y and should be placed in the relevant cell of the grid. Note that the collection can change during runtime which should update the grid items. I couldn't find any good solution. But maybe it is even possible without using the code-behind? Don't mind conversion or something. This stuff changes anyway. The used collection class isn't important. (You can choose one.) How can I solve this problem? Any appropriate suggestions
