I want to add objects dynamicly to a ObservationCollection, which then should add buttons with a Content (value) of a field of the object to a panel.
App.xaml.cs using System.Windows;
namespace WpfApp1
{
public partial class App : Application
{
}
}
MainWindow.xaml
<Window x:Class="WpfApp1.MainWindow"
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"
Title="MainWindow" Height="350" Width="525">
<Grid>
<ItemsControl Name="dashboardList">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Button Content="{Binding Name}" />
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Grid>
</Window>
DashboadViewModel.cs
using System.Collections.ObjectModel;
namespace WpfApp1
{
public class DashboardViewModel
{
public ObservableCollection<Dashboard> Dashboards { get; set; }
public DashboardViewModel()
{
LoadDashboards();
}
public void LoadDashboards()
{
ObservableCollection<Dashboard> dashboards = new ObservableCollection<Dashboard>();
dashboards.Add(new Dashboard { Name = "Dashboard1" });
dashboards.Add(new Dashboard { Name = "Dashboard2" });
Dashboards = dashboards;
}
}
}
Dashboard.cs
namespace WpfApp1
{
public class Dashboard
{
public string Name;
}
}
How do I get to create the buttons, am I on the right track with the ItemControl?
public string Name
should be changed to be a public property to support data binding:
public class Dashboard
{
public string Name { get; set; }
}
Besides that, an instance of DashboardViewModel should be assigned to the Window's DataContext
property and the ItemsControl's ItemsSource
property should be bound like this:
<Window ...
xmlns:local="clr-namespace:WpfApp1">
<Window.DataContext>
<local:DashboardViewModel/>
</Window.DataContext>
<Grid>
<ItemsControl ItemsSource="{Binding Dashboards}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Button Content="{Binding Name}" />
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Grid>
</Window>
If necessary, you can access the view model instance in the Window's code behind like this:
var vm = (DashboardViewModel)DataContext;
vm.LoadDashboards();
