问题 I've abandoned the MVVM midway through app development just to get this app out. I've written a method in the code behind to update the database/datagrid etc. My application navigation is using Commands to the ViewModel firing some event but never touches the code-behind except one time to initialize the class. So basically I push the button one time and it works with the default initial setting but I can't call my code-behind Update() method anymore once the view as been intialized. How can

问题 I am trying to assign an icon from any Mahapps.Metro.IconPacks to an rectangle respectively to a button with text. How do I do this if I want to use the new IconPacks? Effectively I need to convert an Mahapps.Metro.IconPacks.PackIconModernKind to VisualBrush or canvas or actually anything I can use to place it in a button. Any help is appreciated!

问题 This question already has answers here : Refresh Page C# ASP.NET (10 answers) Closed 4 years ago . I'm kind of new at this and my English is also poor.

Apparently my timer works fine because when i debugged it it enters into the function Timer1_Tick , but it doesn't refresh my Page. Here is the code: System.Timers.Timer Timer1 = new System.Timers.Timer(); Timer1.Interval = 10000; Timer1.Elapsed +

问题 My end goal is to have a ListBox show me a list of colors, where the value of the background color is the color itself. Eventually, this ListBox will load a previously saved collection of colors, but for now I'm just trying to get it to work with dummy data - a dictionary I filled up using the colors from System.Windows.Media.Colors ( <string, Color> , where string is the friendly name and Color is a custom class that only contains the Red , Green , Blue , and Hex values for the color).

Ultimately I want the content pages to have access to a connection object and

问题 I'm working on some .Net XAML application using MVVM pattern. According to MVVM I keep my app logic in VM and in Code Behind I do UI-related actions. But I need to execute some UI-related code in Code Behind in respond to some logic in VM. Example: I need to show an error message (custom toast notification in my case) when login operation failed. Login operation resides in VM, but I can't use any UI-specific classes in my VM, so I made an event in VM and hooking up to in in Code Behind, doing

问题 When I publish any type of asp.net application, my code is precompiled into various assemblies. I would like to avoid this so that I can upload an aspx page and its corresponding codebehind file. I understand the benefits of doing it either way, but what is desired here is the least risky way to publish changes. How does one properly deploy an asp.net project without compiling assemblies? Is the process different for each model (web app, MVC..) 回答1: Sounds like you have a Web Application
