dependency-properties

I have a UWP project, and I am trying to get a binding on my ValueConverter . It is based on this guide . I have created a DependencyProperty on the ValueConverter , but it is always null , instead of an element of type Vehicle . There is my code: MainPage.xaml <Page x:Class="Project.Pages.MainPage" 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" mc:Ignorable="d" xmlns:conv="using:Project

So i have this issue: I have created a UserControl (basically a textbox and label). This user control I am able to Bind using a Dependency Property. I have a ListView in which I can put a textbox in the datatemplate and bind the "text" property to the binded value. so far so good. but now if I try to put the UserControl into that very same scenario the DependencyProperty stops working. Here is the code: [ListView] <ListView x:Name="DtContactDetailListView" ItemsSource="{Binding}"> <ListBox.ItemTemplate> <DataTemplate> <UserControl:tbx label="{Binding detail}" text="{Binding value}"/> <

I find that when I change a class from public class MarkdownEditorOptions : ObservableObject to public class MarkdownEditorOptions : INotifyPropertyChanged, DependencyObject as I wanted to use dependency properties, I get the error Default value for the 'Options' property cannot be bound to a specific thread. ...\Views\ShellView.xaml Options is declared as a dependency property on ShellViewModel public MarkdownEditorOptions Options { get { return (MarkdownEditorOptions)GetValue(OptionsProperty); } set { SetValue(OptionsProperty, value); } } public static readonly DependencyProperty

I have a DependencyProperty in my custom UserControl that looks like this: public static readonly DependencyProperty ColumnWidthProperty = DependencyProperty.Register("ColumnWidth", typeof(int), typeof(CallBoard), new PropertyMetadata(150)); public int ColumnWidth { get { return (int)GetValue(ColumnWidthProperty); } set { SetValue(ColumnWidthProperty, value); } } In Expression Blend 3, I have this: <UserControl 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"

This question already has an answer here : Closed 7 years ago . Possible Duplicate: Method group in VB.NET? While reading an answer I got this code: public static class Helper { public static bool GetAutoScroll(DependencyObject obj) { return (bool)obj.GetValue(AutoScrollProperty); } public static void SetAutoScroll(DependencyObject obj, bool value) { obj.SetValue(AutoScrollProperty, value); } public static readonly DependencyProperty AutoScrollProperty = DependencyProperty.RegisterAttached("AutoScroll", typeof(bool), typeof(Helper), new PropertyMetadata(false, AutoScrollPropertyChanged));

is it because the controls programmers are lazy, too hard to implement or not knowledgeable? Wether they are custom controls from 3rd party vendors or Microsoft itself, very much controls have often clr properties instead of DP. Result is I can not bind to them and is wpf not all about binding? :/ My next side question would be, why do so many wpf controls offer visual parts but they are not member of the visual tree ? see wpf datagrid columns, headers... What do you think? You don't provide examples of the controls you're thinking of, and even then it would be hard to peer into the
