问题 When I drag a control from the toolbox on to the Visual Studio 2008 WPF design surface, it sets a margin based on where I dropped it and a default size. Is there any way to prevent VS setting those? When I drop a control on a stackpanel I want it to flow in to the existing controls in the panel. Thanks! 回答1: I've never found a way to prevent this. I just type the XAML instead. EDIT : I wrote the above nearly three years ago. In the meantime, it would appear that the design-time experience has

问题 I'm using Qt Designer (well, Qt Creator actually, but specifically the part derived from Qt Designer), and I've added a few QComboBox items to a dialog with a constant list of items. I need to map the items in the combo box to strings (which are distinct from the displayed strings). The best idea I've come up for it is to use the QComboBox::itemData function to get the needed string from the selected item, but I'm having trouble adding the associated strings to the items. I've looked all over

问题 Often times while using QT designer I find myself needing to re-size things either by shrinking or expanding them. Whenever I try to do this the program does not allow me and simply reverts to the original default size it gives me when placing the object within my window, regardless of the layout I have. Why does it do this? And is it possible to change this so that I can re-size things to my own will without restrictions? I have been trying to learn how to properly use QT designer, but I can

问题 After several days of happily hacking away on this C# app using Visual Studio 2008, I get struck by a barrage of error dialogs showing: Code generation for property ' valueMember ' failed. Error was: ' Object reference not set to an instance of an object .' This happens now often when I make a tiny change in the designer, e.g. shift a control a few pixels, and then try to save. Several such error dialogs appear each second, keeping me busy cancelling all those by hammering the Enter key while

问题 I'm an experienced C# developer but a WPF newbie. Basic question (I think) that I can't find an answer to by web searching. Here's the simplified use case... I want to display a string in a WPF TextBlock. So I write some C# code in codebehind of my XAML control... public class MyCoolControl : UserControl { public void InitializeMyCoolControl() { this.DataContext = "SomeStringOnlyAvailableAtRuntime"; // Perhaps from a database or something... } } And I set up my XAML like this: <UserControl ..

问题 For a WinForms control, I'd like to move certain settings into a sub object. One of them is a custom class containing all UI Strings, the other a OpenFileDialog: class MyControl: Control { // ... private OpenFileDialog m_dlgOpen = new OpenFileDialog(); public OpenFileDialog DialogOpen { get { return m_dlgOpen; } } } This adds the sub object to the designer, and allows to edit its properties (e.g. title, default extension, filter). However, the changes are nto added to the InitalizeComponent

问题 every time we open a *.xaml file in our project - we see not working designer and a lot of messages 'type not found' 'assembly not found' etc. After a couple of experiments, i found out a root of a problem : create new WPF application, create a folder in project root, add some value converter to folder, try to use it on your 'MainWindow.xaml' you will probably write something like this : xmlns:Folder="clr-namespace:WpfApp.Folder" and then <Window.Resources> <Folder:SomeValueConverter x:Key=

问题 Problem: The Windows Forms designer does not work for an inherited user control when the base class is implementing an interface from another assembly. Platform: VS 2010 SP1, .NET 4.0 Framework Error: The designer could not be shown for this file because none of the classes within it can be designed. The designer inspected the following classes in the file: MyControl --- The base class 'MyBaseControlLib.MyBaseControl' could not be loaded. Ensure the assembly has been referenced and that all

问题 I seem to have a sudden issue with my XAML Designer view in VS2012, and a similar behavior in Blend as well. the view has stopped updating and I'm unable to see any changes immediately if I change any properties. if I scroll or Pan, the Phone chrome seems to move but the content stays put. It gets restored upon slightly adjusting the borders or restarting the page. has anyone else faced this issue? do you know what I need to do? I'm using Visual Studio 2012 Professional (Update 2) this image

问题 I'm trying to customize the Windows Forms Designer's code generation for InitializeComponent . The MSDN article "Customizing Code Generation in the .NET Framework Visual Designers" contains a section "Controlling Code Generation" that explains the basics of how this can be done. I've closely followed an example in the above article: //using System.ComponentModel.Design.Serialization; class SomeFormSerializer : CodeDomSerializer { public override object Serialize(IDesignerSerializationManager
