问题 in my Silverlight 4 application, I have a ScrollViewer. I want to change the width of the vertical Scrollbar of the Scrollviewer, to make it a bit thinner.

I was thinking about something like: MyScrollViewer.VerticalScrollbar.Width = 8; But there is no such Property. Any idea, how to make the scroll bar thinner? Thanks in advance, Frank 回答1: There is no direct way of getting the vertical scrollbar of

Do i *have* to use ObservableCollection in Silverlight WCF client?

由 こ雲淡風輕ζ 提交于 2019-12-22 12:18:37
问题 When accessing Silverlight in WCF you get proxies generated with ObservableCollection Thats fine when you're databinding, but a little clumsy when you're just calling a method. For instance the following service method : [OperationContract] public SearchOrdersMsgOut SearchOrders(ShippingStatusType[] shippingStatuses, string[] orderId) { } gets generated with ObservableCollection . What! They're just parameters. Why would I ever want to 'observe' them? I'm fine if I have to do this - but it

Target Silverlight Version is stuck

由 …衆ロ難τιáo~ 提交于 2019-12-22 11:36:06
问题 I have my shiny new Visual Studio 2010. I want to develop a Silverlight 4 web app with it. I made a project and it told me that I needed to update my Developer version of Silverlight. I followed the link provided and did what it suggested. I then went back and created my project (under a different directory). But when I try to select the target version of Silverlight all I can see is Silverlight 3. What do I need to do to get this to show the Silverlight 4 option? 回答1: Make sure you've

Cleanest way to bind a Button's visibility to the contents of two textboxes

由 帅比萌擦擦* 提交于 2019-12-22 10:17:21
问题 I have a Button within my app whose "enabledness" I have bound to whether a TextBox is empty as so: <Button Content="Go" IsEnabled="{Binding Text, Converter={StaticResource EnableIfStringNotEmptyDataSource}, ElementName=MyTextbox}"/> (implementation of EnableIfStringNotEmptyDataSource omitted for brevity).
