问题 What I'm trying to do : I have 2 comboboxes, a "regular" one, and a filtrable one. On the filtrable combobox ItemsSource is binded to a property of the first combobox SelectedItem .

问题 I am using entity framework 6, .Net framework 4 and code first. I am able to get the validation errors by using GetValidationResult method. But I was not able to show the validation message like the one given in the below image. How to achieve this? My Code: <Label Content="Name" /> <Grid Grid.Row="0" Grid.Column="2"> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto" /> </Grid.ColumnDefinitions> <TextBox x:Name="txtName" Width="200" Margin="8,0,0,0" MaxLength="150" Text="{Binding Path

问题 If one binds to a listbox's ItemsSource to a list type structure such as an ObservableCollection (or any value-only container really) with the type of a class ( List< MyClass> ) one can access the properties of said class. But if one has a Dictionary<long, MyClass> and binds the itemssource to Dictionary.Values one can not access the class properties anymore. So basically this is my XAML <ListBox ItemsSource="{Binding bm.Values}"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel> <TextBlock

问题 I'm writing a mobile app using Xamarin and I have a static class called Strings that wraps my RESX resources. I want to use x:Static to bind to these in my XAML files. This is working if I have a single static class with static properties to bind to. I'm cutting out some comments and other non-essential bits, but it basically looks like this: namespace MyCompany.Resources { public static partial class Strings { public static string LabelUsername { get { return Resources.LabelUsername; } } } }

问题 According to the Control template documentation on MSDN, the officially-supported way to view a Control's default templates and styles is with Visual Studio's Designer (well, technically the Document Outline , but that only works with the Designer turned on): A fast way to apply themes to your controls is to right-click on a control on the Microsoft Visual Studio Document Outline and select Edit Theme or Edit Style (depending on the control you are right-clicking on).
