I have a problem. I want to give a button a command from ViewModel, which is outside of ItemsRepeater ItemsSource. I need help on how to do such binding
Button in my ItemsRepeater
<Button Command={Binding TestClick} Grid.Column="0" HorizontalAlignment="Stretch" Foreground="#6264a7" HorizontalContentAlignment="Center" CornerRadius="0" Background="#2f2f2f" FontSize="20">Details</Button>
My ItemsRepeater
<ItemsRepeater.ItemTemplate>
<DataTemplate>
<DockPanel Margin="30,0,30,50">
<StackPanel>
<TextBlock Background="#2f2f2f" FontSize="25" Foreground="AntiqueWhite" TextAlignment="Center" Padding="0,8,0,8" Text="{Binding Name}"></TextBlock>
<TextBlock TextAlignment="Center" Background="#2f2f2f" Foreground="AntiqueWhite" Height="40" FontSize="20" Padding="0,8,0,0" Text="{Binding Date}"></TextBlock>
<TextBlock TextAlignment="Center" Background="#2f2f2f" Foreground="AntiqueWhite" Height="40" FontSize="20" Padding="0,2,0,0" Text="{Binding EventType}"></TextBlock>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="50*" />
<ColumnDefinition Width="50*" />
</Grid.ColumnDefinitions>
<Button Command={Binding TestClick} Grid.Column="0" HorizontalAlignment="Stretch" Foreground="#6264a7" HorizontalContentAlignment="Center" CornerRadius="0" Background="#2f2f2f" FontSize="20">Details</Button>
<Button Grid.Column="1" HorizontalAlignment="Stretch" HorizontalContentAlignment="Center" Foreground="#a4373a" CornerRadius="0" Background="#2f2f2f" FontSize="20">Delete</Button>
</Grid>
<ProgressBar Height="10" CornerRadius="0" Value="{Binding TimeLeft}" Minimum="0" Maximum="{Binding DifferenceBetweenDates}" Foreground="{Binding ProgressBarColour}" />
</StackPanel>
</DockPanel>
</DataTemplate>
</ItemsRepeater.ItemTemplate>
</ItemsRepeater>
My ViewModel:
using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Anniverse.ViewModels
{
class MainPanelViewModel : ViewModelBase
{
public string CurrentDate => DateTime.Today.ToString("dd.MM.yyyy");
public ObservableCollection<Event> Events => new Connector().GetEvents();
public void TestClick()
{
Console.WriteLine("Hello test");
}
}
}
CodePudding user response:
The easiest way to achieve that would be to bind to the ancestor
Command="{Binding $parent[ItemsRepeater].DataContext.YourCommand}"
Note that you need to define the ICommand
in your view model for the command binding to make it work, you can find an example here
EDIT: I was not aware of it, but binding directly to methods should work as well
