How can I pass the event argument to a command using triggers?

由 馋奶兔 提交于 2019-11-26 22:40:26
问题 So I have a simple setup, an autocompletebox with its Populating event that I want to bind to a command. I use clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity (is there a better namespace for doing this?) It's not a big deal to bind it, the big deal is to pass that PopulatingEventArgs argument to the bound command. So how do I do it according to the best practices of PRISM in particular and MVVM in general? 回答1: There is no built-in way, so here is how I do it

Adding stored procedures complex types in Entity Framework

由 半城伤御伤魂 提交于 2019-11-26 18:36:29
I am trying to use a stored procedure in Entity Framework that returns nothing. I did the following: Added a function (right click on stored procedure -> add -> function import-> Complex Type -> Get column information -> create New Complex-Type) My function name: summarySP_Result . After building the project the entity class is not generated in Generated_code ( BusinessAccount.web.g.cs ) But entity classes for tables and views are all created but nor for stored procedure. Can anybody give the idea why it is not generated entity class in BusinessAccount.web.g.cs ? Update : Let me confirm

What is the replacement for DataTrigger in Silverlight

由 做~自己de王妃 提交于 2019-11-26 18:18:29
问题 This is my scenario. I have 2 Properties. Type and State. Type is an Enum with 3 values eg, ball, car, arrow. State is an int which would accept 3 state values eg., -1, 0, 1. Also, I have 9 images for each state values. Like, if I select type as ball and value as -1, I want to display a Red color ball. If I select type as arrow and value as 1, I want to display a up arrow. etc., I'm able to do this in WPF. I created 3 DataTemplates with an empty Image. Then, I use DataTrigger to check and

I know you can't in previous versions of silverlight, you can only databind to public class properties and anonymous type properties are internal. Just wondering if anyone has tried it in silverlight 4? 回答1: You can... If you expose your internals. Place this in your AssemblyInfo.cs: [assembly: System.Runtime.CompilerServices.InternalsVisibleTo("System.Windows")] 来源： https://stackoverflow.com/questions/2684954

How to access a specific item in a Listbox with DataTemplate?

由 元气小坏坏 提交于 2019-11-26 17:43:50
I have a ListBox including an ItemTemplate with 2 StackPanels. There is a TextBox in the second StackPanel i want to access. (Change it's visibility to true and accept user input) The trigger should be the SelectionChangedEvent. So, if a user clicks on an ListBoxItem, the TextBlock gets invisible and the TextBox gets visible. XAML CODE: <ListBox Grid.Row="1" Name="ContactListBox" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" ItemsSource="{Binding Contacts}" Margin="0,36,0,0" SelectionChanged="ContactListBox_SelectionChanged"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel

问题 Im migrating my Chart code from visifire to Toolkit. I would like to know the counter part of ColorSet property[sample value Caravan,Picasso..] of Visifire to Toolkit. Is there any?
