如果显示是ItemsControl.ItemsSource空 [英] Show if ItemsControl.ItemsSource is null

问题描述

问候，

我有一个ItemsControl的我改变了模板来显示单选按钮在绑定的ItemsSource的每一个对象。

I have a ItemsControl which template I changed to show a RadioButton for every object in the binded ItemsSource.

然而，的ItemsSource可以是空的，当它是空的，我想展现一个默认值。喜欢的东西的绑定列表中没有的项目供您选择...

However the ItemsSource can be empty and when it is empty I'd like to show a default value. Something like "The binded list contains no items for you to select"...

我想到的一个方法是将ItemsControl.Visibility设置为折叠，并有一个TextBlock .Vsibility到可见其显示文本。但是这将包括更多数据。

One way I thought of is to set the ItemsControl.Visibility to Collapsed and have a TextBlock.Vsibility to Visible which shows the text.. But this would include a lot more data.

是否有可能显示一个默认值，如果ItemsControl.ItemsSource为空？

Is it possible to show a default value if the ItemsControl.ItemsSource is null?

If I understood correctly, I think you can solve your problem by creating an IValueConverter.
