问题 Playing with MultiBinding : What I want: clicking either checkbox should toggle all others. Problem: clicking A doesn't change B , clicking B doesn't change A . Result works. Question: how would I fix it, while still using MultiBinding ?

问题 I am unable to change the contents of the ContentTemplateSelector . Based on the two properties Eligibility and ListOfThings , the text block is updated and it is achieved by multibinding.

问题 Multibinding is a pretty powerful feature in WPF, why is it not supported in silverlight? They never got around to adding support to it? It's too big to fit in the .NET framework? Will it be coming in Silverlight 5? Anyone know the answers? Thanks! 回答1: It's not supported out of the box, but you can throw together an approximation that will maybe do what you want: look here and here Microsoft has a good page on what's coming up in Silverlight but no mention of multibinding. 来源： https:/

问题 I'm trying to have column sort on numeric content. Multi-binding converter works fine. This solution will set SortMemberPath to null I've tried a variety of ways, and scoured the internet substantially. Code has been modified from original for security purposes. <DataGridTemplateColumn x:Name="avgPriceColumn"> <DataGridTemplateColumn.CellTemplate> <DataTemplate> <TextBlock> <TextBlock.Text> <MultiBinding Converter="{StaticResource avgPriceConverter}"> <Binding Path="NumberToDivideBy" />

问题 I want to reuse a DataTemplate for multiple columns in a ListView. Given the two XmlDataProvider I select values from the second by using the selected item in the first. This works if I specify the additional resource in the DataTemplate . But this forces me to duplicate the code of the DataTemplate and just exchange the addtional resource. What I would like to do is this: <Window x:Class="LayoutTests.Window2" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http:/
