ItemsControl类型的值无法添加到TimelineCollection类型的集合或字典中 [英] A value of type ItemsControl cannot be added to a collection or dictionary of type TimelineCollection
问题描述
您好，我的目的是在点击现有按钮后生成一些新按钮。
我需要创建一个点击触发器。点击原点按钮后，我想添加包含新按钮的ItemsControl。
Hello, my intention is to generate some new buttons after click on already existing button.
I need to create a click trigger. After click on origin button i want to add there ItemsControl containing new buttons.
请有人知道我怎么能执行包含ItemsControl的触发器（生成新按钮，但这个生成对我有用） ）。
Does please somebody have idea how could i execute trigger containing ItemsControl (generating new buttons, but this generating already works to me).
这是我的整个XAML，我在里面描述了关键代码部分：

嗨RadekJak，
Hi RadekJak,
根据你的描述，你想点击按钮添加收藏品，对吗？如果是，您可以查看以下代码，请在项目中添加这些命名空间：
According to your description, you want to click button to add item for collection, am I right? If yes, you can take a look the following code, please add these namespaces in your project:
xmlns:ei="http://schemas.microsoft.com/expression/2010/interactions"
xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity"
xmlns:command1="http://www.galasoft.ch/mvvmlight"您可以通过NuGet Package下载...
You can download by NuGet Package...
<Grid>
<ItemsControl ItemsSource="{Binding Shippers}">
<ItemsControl.ItemTemplate>
<DataTemplate DataType="{x:Type Button}">
<WrapPanel Background="Green" Orientation="Horizontal">
<Button
Width="50"
Height="50"
Margin="0,0,5,5"
Background="Red"
Content="{Binding BtnLabelShipper}">
<i:Interaction.Triggers>
<i:EventTrigger EventName="Click">
<command1:EventToCommand Command="{Binding RelativeSource={RelativeSource AncestorType=Window, Mode=FindAncestor}, Path=DataContext.buttonclick}" />
</i:EventTrigger>
</i:Interaction.Triggers>
</Button>
</WrapPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Grid>
public partial class Window1 : Window
{
public ObservableCollection<Shipper> Shippers { get; set; }
public RelayCommand buttonclick { get; set; }
public Window1()
{
InitializeComponent();
Shippers = new ObservableCollection<Shipper>()
{
new Shipper(){BtnLabelShipper="test1"},
new Shipper(){BtnLabelShipper="test2"},
new Shipper(){BtnLabelShipper="test3"}
};
buttonclick = new RelayCommand(click);
this.DataContext = this;
}
public void click()
{
MessageBox.Show("OK!");
Shippers.Add(new Shipper() { BtnLabelShipper = "test4" });
}
}
public class Shipper
{
public string BtnLabelShipper { get; set; }
}
最好的问候，
Cherry
