Listpicker Multiple selection and DisplayMemberPath

由 会有一股神秘感。 提交于 2019-12-22 18:42:56
问题 I have a collection of my custom entity that is bound to the listpicker using the ItemsSource property. I also have selection mode set to Multiple so I have a checkbox with each item in the FullMode picker. This picking works, fine, and I can easily access all objects that were picked thru code. What I'm having troubles with is the DisplayMemberPath . I want to display something more friendly than the namespace of the object that is selected. Perhaps a count of selected items, or a comma

WCF/Silverlight: Why use a ChannelFactory instead of a Client?

由 喜夏-厌秋 提交于 2019-12-22 17:39:13
问题 In inherited a project that uses a ChannelFactory instead of a Client for WCF calls. Why would you do that? Also, is it safe to cache the result of a ChannelFactory.CreateChannel() call or should you create a new one each time? 回答1: Creating the WCF client is a two-step process: creating the channel factory using that channel factory, create the actual channel Step 1 is rather expensive in terms of processing power and speed - so if you can create the channel factory and then cache is
