[英]Dynamically add multiple buttons to wpf window?
how would i add multiple buttons to a window in c#?我如何将多个按钮添加到 c# 中的窗口? here's what i need to do... i'm getting multiple user values from a dictionary (within reason, only @ 5-6 values).
这是我需要做的...我从字典中获取多个用户值(在合理范围内,只有@ 5-6 个值)。 for each value, i need to create a button.
对于每个值,我需要创建一个按钮。 now, how do i name the button, not the text within the button?
现在,我如何命名按钮,而不是按钮内的文本? how do i define the "click" method for each button (they will all be different)?
我如何为每个按钮定义“点击”方法(它们都会不同)? and how do i erase the button if i don't want it anymore?
如果我不再想要它,我该如何擦除按钮?
I would encapsulate the whole thing, there normally should be no point in naming the button.我会把整个事情都封装起来,通常没有必要给按钮命名。 Something like this:
像这样的东西:
public class SomeDataModel
{
public string Content { get; }
public ICommand Command { get; }
public SomeDataModel(string content, ICommand command)
{
Content = content;
Command = command;
}
}
Then you can create models and put them into a bindable collection:然后你可以创建模型并将它们放入一个可绑定的集合中:
public ObservableCollection<SomeDataModel> MyData { get; } =
new ObservableCollection<SomeDataModel>();
Then you just need to add and remove items from that and create buttons on the fly:然后你只需要添加和删除项目并动态创建按钮:
<ItemsControl ItemsSource="{Binding MyData}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Button Content="{Binding Content}" Command="{Binding Command}"/>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>

Consider you have a StackPanel
named sp考虑您有一个名为 sp 的
StackPanel
for(int i=0; i<5; i++)
{
System.Windows.Controls.Button newBtn = new Button();
newBtn.Content = i.ToString();
newBtn.Name = "Button" + i.ToString();
sp.Children.Add(newBtn);
}
To remove button you could do要删除按钮,你可以做
sp.Children.Remove((UIElement)this.FindName("Button0"));
Hope this help.希望这有帮助。
