I want to draw boxes from a list of shapes specified in my ViewModel.
The view:
<Window x:Class="DrawingBoxesAndLines.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:my="clr-namespace:DrawingBoxesAndLines.ViewModels" Title="MainWindow" Height="350" Width="525"> <Window.Resources> <my:MainWindowViewModel x:Key="mainVM" /> </Window.Resources> <Grid DataContext="{StaticResource ResourceKey=mainVM}"> <ItemsControl Margin="10" ItemsSource="{Binding Rectangles}"> <!--http://msdn.microsoft.com/en-us/library/system.windows.controls.itemscontrol.aspx--> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <Canvas /> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> <ItemsControl.ItemTemplate> <DataTemplate> <Rectangle Width="{Binding Width}" Height="{Binding Height}" Fill="Red"/> </DataTemplate> </ItemsControl.ItemTemplate> <ItemsControl.ItemContainerStyle> <Style> <Setter Property="Canvas.Left" Value="{Binding X}"/> <Setter Property="Canvas.Top" Value="{Binding Y}"/> </Style> </ItemsControl.ItemContainerStyle> </ItemsControl> </Grid></Window>
ViewModel:
using System.Collections.Generic;namespace DrawingBoxesAndLines.ViewModels { class Box { public int X { get; set; } public int Y { get; set; } public int Width { get; set; } public int Height { get; set; } } class MainWindowViewModel { public List<Box> Rectangles { get; set; } public MainWindowViewModel() { Rectangles = new List<Box>(); Rectangles.Add(new Box { X = 10, Y = 10, Height = 50, Width = 100 }); Rectangles.Add(new Box { X = 150, Y = 60, Height = 50, Width = 100 }); } }}
