I'm new to Silverlight, so I don't have a complete grasp of all the controls at my disposal. What I would like to do is use databinding and a view model to maintain a collection of items. Here is some mock code for what I'd like to do:
Model
public class MyItem
{
public string DisplayText { get; set; }
public bool Enabled { get; set; }
}
ViewModel
public class MyViewModel : INotifyPropertyChanged
{
private ObservableCollection<MyItem> _myItems = new ObservableCollection<MyItem>();
public ObservableCollection<MyItem> MyItems
{
get { return _myItems; }
set
{
_myItems = value
NotifyPropertyChanged(this, "MyItems");
}
}
}
View
<Grid x:Name="LayoutRoot" Background="White">
<StackPanel ItemsSource="{Binding MyItems}">
<StackPanel Orientation="Horizontal">
<CheckBox "{Binding Enabled, Mode=TwoWay}"></CheckBox>
<TextBlock Text="{Binding DisplayText, Mode=TwoWay}" />
</StackPanel>
</StackPanel>
</Grid>
So my end goal would be that every time I add another MyItem
to the MyItems
collection it开发者_如何学编程 would create a new StackPanel with checkbox and textblock. I don't have to use a stack panel but just thought I'd use that for this sample.
Looks like you want a <ListBox>
, then set the <ListBox.ItemTemplate>
to your <StackPanel>
something like this.....
<ListBox ItemsSource=”{Binding Classes, Source={StaticResource model}}”>
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<CheckBox "{Binding Enabled, Mode=TwoWay}"/>
<TextBlock Text="{Binding DisplayText, Mode=TwoWay}" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
here is a great example (it's WPF, but should only be minor changes for silverlight)
yes, looks like you want a <ListBox>
<UserControl
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Class="SilverlightApplication4.MainPage"
Width="640" Height="480">
<UserControl.Resources>
<DataTemplate x:Key="ItemTemplate">
<StackPanel Orientation="Horizontal">
<CheckBox IsChecked="{Binding Enabled, Mode=TwoWay}"/>
<TextBlock Text="{Binding DisplayText}"/>
</StackPanel>
</DataTemplate>
</UserControl.Resources>
<Grid x:Name="LayoutRoot" Background="White" DataContext="{Binding Source={StaticResource SampleDataSource}}">
<ListBox Margin="0,0,8,0" ItemTemplate="{StaticResource ItemTemplate}" ItemsSource="{Binding Collection}"/>
</Grid>
This code will give you a ListBox with all your Data bound to a Checkbox and TextBlock with the Checkbox first and TextBox next to it.
