问题 I have this use case that is very similar to the robot-legs example of Guice, except I don't know how many "legs" I have. Therefore I can't use the annotations needed for the robot-legs example. I expect to gather all these "legs" in an java.util.Set with Guice's Multibindings extension. Technically, in a PrivateModule I would like to expose an implementation directly as an element of the set that will be provided by the Multibindings extension. I just don't know how to do that. For reference

问题 Is there any way to have to tabcontrol take the size of the largest tab item (well, actually, the tabitem's content)? Since the tabcontrol has no specific size assigned it should autosize: it does that correctly, but when you switch tabs it automatically resizes itself to the height (and width) of the contents of the currently selected tab. I don't want the resizing to happen, and let the tabcontrol assume the height of the largest item, but still have it autosize itself. Any clues? I tried

问题 I'm currently using the TextBlock below to bind the value of a property named Name : <TextBlock Text="{Binding Name}" /> Now, I want to bind another property named ID to the same TextBlock . Is it possible to bind two or more values to the same TextBlock ? Can it be done with simple concatenation, like Name + ID and, if not, how else could this be approached? 回答1: You can use a MultiBinding combined with the StringFormat property. Usage would resemble the following: <TextBlock> <TextBlock

问题 I try to add new line inside Label ContentStringFormat : Content="{Binding Path=(my:MyData.Files)}" ContentStringFormat="{}Number of files:\n {0:#,0}" Any suggestions ? 回答1: You can't use C# escape characters in XAML code. For XAML there are other possibilities: HEX represenation of CR/LF (or just line feed ): ContentStringFormat="{}Number of files: {0:#,0}" Bind to string that initially contains new line charachters where you need them Use multibinding with Environment.NewLine

The double is bound to a particular data source and the formatter is a property in the view model. The problem I'm having is that I'm unable to bind to the view model property. This is my code in xaml <StackPanel Grid.Row="0" Grid.Column="1"> <TextBlock HorizontalAlignment="Left" Style="{StaticResource
