The Silverlight toolkit for Windows Phone 7.1 Control described earlier is essentially a user-defined control. You can define some controls as needed. The following is a simple waitingbox with animations: 1. Create: usercontrol inherits the control class "usercontrol". That is to say, all attributes and methods of the control are available. What you need must be expanded by yourself. XAML: Generally, the

Usercontrol control.After adding usercontrol, it should appear in toolbox according to the statement. If you cannot find it, you need to set it:Choose tools> Options> Windows Forms designer> General> toolkit> autotoolboxpopulate to true.This method does not generate DLL for this usercontrol.Another method is to create a new usercontrol project, which generates a

Key Points of user control design: System. Windows. Forms. UserControlKey Points of User Control Design A waterfall chart (color chart) function in a recent project is to present the point values in space and time in the form of graphs, such: X coordinates are space, and a pixel in the horizontal direction represents a space unit (for example, 50 meters) Y coordinates are time, and a pixel in the vertical direction represents a time unit (for example, 1 second) Since there is no ready-made colo

The custom control is very flexible and I replace the picture of the control with the field {Get;set;}. However, because it is a relative path, during the IDE editing process, the drag control enters with an error that the picture cannot be accessed. The reason is that all public fields are automatically assigned the initial value (Bool,enum) when you drag the control. To solve this problem, I'm looking for ways to prevent certain fields from being assigned automatically when the control is drag

Search online for information about how to use C # To develop ActiveX ControlsArticleIt basically seems to be an article in the cited blog Park. But that article is used in IE. However, I have tried it. If it cannot be referenced in VB6, the system prompts that it cannot be registered as an ActiveX control. Later, we found that Microsoft has provided a toolkit "Microsoft InterOP forms Toolkit 2.0" to conveniently implement this function. After the installation is complete, when you create a VB

Learning and using asp.net mvc for such a long time, or asp.net obsession. Can I show aspx or user control in asp.net mvc? This inspiration (not the inspiration, but the idea) is from the previous days have written a "multiple view results displayed in a shared preview view" Http://www.cnblogs.com/insus/p/3633298.html There is a render method. So that when you think of the previous development of ASP.net, you often render user controls. That is to say, after render the page, it is converted to

Add CustomValidator verification to a text control in the user control, and set the ClientValidationFunction attribute of CustomValidator to the client's Validate (source, args) method, If the user control is used in two places on a page, and then click save button for verification, you will find that this verification is not the one you want. Why, originally, two user controls were used Two Validate methods are generated, but only one method is used. Therefore, only one of them can be ver

I have seen a few people asking the above questions recently. Here I will give you a reference answer, but the specific situation should be handled as some special conditions may be required for the functions implemented in Usercontrol, for example, if it depends on some other classes or resources, you should be careful. When debugging is required, check whether the complexity determines whether to continue or simply write Custom Controls.A. Generate
