It inherits from the mature mode of SharePoint Portal Server, you can use the smallest code to create richer performance, for example, you can use the drag-and-drop method to create a page layout. All the controls related to it are in the namespace system.
16.1 Basic characteristics of data browsing parts
Most of the data-browsing widgets evolved from standard components, which have similar characteristics, such as Tdbgrid and Tstringgrid parts, Tdbedit and tedit parts, Tdblistbox and Tlistbox, etc. Only the data browsing part is a field information that is specifically used to display and edit records in the data
15.6.1.4 Field Parts Access

19.2.2.4 Registered Parts
Writing parts and their properties, methods, and events is only part of the part creation process. While parts are available with these features, the real power of parts is the ability to manipulate them at design time.
The following steps are required to make a part available at design time

19.2.2.1 Create Properties
Properties are the most specific parts of a part, primarily because they can be seen and manipulated by the user at design time and can be returned immediately in the interactive process. Properties are also important, because if they are designed, they will make it easier for users to use and maintain themselves easily.

I believe that a lot of people have their own experience in the use of parts in the axure, and this combination of my use of these parts, the use of part of parts, and then make some additions, to the point. Here the basic use is not to repeat, directly put on a number of complementary use. Well, no more gossip, come directly.

Because all event-handling procedures are procedures, the only way to return information from an event-handling process is through the Var parameter. Custom parts can use this information to determine whether and how events are handled after the user event handling process is
Data-browsing widgets are used primarily to display and edit data in database tables, so they are often referred to as data control parts or data-aware parts, which are on the Datacontrols page of the part selection board, Figure 16.1 shows all the data browsing widgets on the Datacontrols page, where the Tdbgrid part is used for full-screen display and editing of records in database tables, Tdbnavigator fo

This article will teach you how to use synchronous serialization threads to access key code parts. I will use an example to explain why some multi-threaded programs must start with synchronization. Next I will discuss the synchronization mechanism of Java and the synchronized keyword about the monitor and lock. By studying the two problems caused by such incorrect use, I often find that the benefits of the

They will be working on objects in both the design and run stages, and writing parts will require more knowledge about objects than they need, so you should be familiar with Delphi's object-oriented programming.
