Paul Stovell gets development questions and he's not afraid to answer them. "I recieved an email this morning as from Steve Pietrek, a Delphi programmer moving to .NET (great choice Steve!). His question essentially asked how would he go about binding a Windows Forms ComboBox to an enumeration such as this: public enum CustomerType { Type1 = 1, Type2 = 2, Type3 = 3 } Fortunately, I figured out how to do this in Trial Balance about a week ago, so I thought I’d share my approach here. The values in an enumeration (Type1, Type2, Type3 in this

This article is pretty extensive with examples and links to more information. Here is a sample to address a common issue: "Binding to a ComboBox or ListBox. This sample demonstrates binding data to a ComboBox. Binding data to a ListBox follows the same model. To bind data to the list of items that are displayed, set the DataSource and DisplayMember properties of the ComboBox. The DisplayMember property is used to determine which property of the State object to display in the ComboBox. For example, the following code binds a ComboBox to an array of

There have been a lot of questions going around about XML and .Net Framework 2.0. Jesse Liberty attempts to answer some of them in his article on the subject: ".NET 2.0 pushes most of ADO.NET into the frameworks level, and provides you with various DataSource controls to make accessing data easy. With the XML DataSource control, you can bind to an XML document just as easily as you bind to tables in a database. If the XML document you load is hierarchical, the data is exposed hierarchically, which makes it ideal to map an XML document to a TreeView

Every once in a while I need to bind an enumerated type to a Windows Forms control, usually a ComboBox. There are lots of articles here on The CodeProject that present various ways to do this, each with their own pros and cons. However, they are generally more complicated than necessary, and in some cases, require a lot of work on either the developer implementing the enum, the developer using it, or both. The Simple Way The simplest is to use the Enum.GetValues() method, setting its result to the DataSource property of the ComboBox. If you have the

Regardless of what element you are binding and the nature of your data source, each binding always follows the model illustrated by the following figure: Basic data binding diagram As illustrated by the above figure, data binding is essentially the bridge between your binding target and your binding source. The figure demonstrates the following fundamental WPF data binding concepts: Typically, each binding has these four components: a binding target object, a target property, a binding source, and a path to the value in the binding source to

Overview Data binding provides a way for developers to create a read/write link between the controls on a form and the data in their application (their data model). Classically, data binding was used within applications to take advantage of data stored in databases. Windows Forms data binding allows you to access data from databases as well as data in other structures, such as arrays and collections. Binding Context Each Windows Form has at least one BindingContext object that manages the CurrencyManager objects for the form. For each data

Introduction In NetUI, data binding allows JSP tags or other UI technologies to read and write data available in the web-tier environment. This document discusses both the implicit objects that are available via NetUI to the JSP author and the expression languages that are used to bind UI objects to those implicit objects. NetUI tags support binding to both read-only and read-write data. Read-only data is usually bound to tag attributes that simply display information on a page. Read-write data is bound with the intention of being updated from a

Data binding is a process that allows an Internet user to manipulate Web page elements using a Web browser. It employs dynamic HTML (hypertext markup language) and does not require complex scripting or programming. Data binding first became available with Microsoft Internet Explorer (MSIE) version 4. It can be used in conjunction with that and all subsequent versions of MSIE to create and view interactive Web sites with a minimum demand on authoring time, subscriber effort, server drive space, and server processing resources. The data binding

Databinding has to be just about one of the coolest features in Flex 2, allowing you to bind a property to the value of a property of another object. When the property of that object is updated, the value of the bound property will automatically be updated. This is mainly used in Flex to update UI components when the data for the model changes. Unfortunately databinding doesn't work for read-only properties. A read-only property (by my definition) is a private instance variable of a class that has a getter function without a matching setter function.

XML data binding refers to the process of representing the information in an XML document as an object in computer memory. This allows applications to access the data in the XML from the object rather than using the DOM to retrieve the data from a direct representation of the XML itself. An XML data binder accomplishes this by creating a mapping between elements of the XML schema of the document we wish to bind and members of a class to be represented in memory. When this process is applied to convert an XML document to an object, it is called

Use of the Web Services architecture provides the following benefits: * Promotes interoperability by minimizing the requirements for shared understanding XML-based interface definition language (NASSL), an XML-based service description (WDS) and a protocol of collaboration and negotiation are the only requirements for shared understanding between a service provider and a service requester. By limiting what is absolutely required for interoperability, collaborating Web services can be truly platform and language independent. By limiting what is

Several essential activities need to happen in any service-oriented environment: 1. A Web service needs to be created, and its interfaces and invocation methods must be defined. 2. A Web service needs to be published to one or more intranet or Internet repositories for potential users to locate. 3. A Web service needs to be located to be invoked by potential users. 4. A Web service needs to be invoked to be of any benefit. 5. A Web service may need to be unpublished when it is no longer available or needed. A Web Services architecture then
