The ASP.NET Web Forms AutoComplete is a textbox control that provides a list of suggestions to select from as the user types. It has several out-of-the-box features such as data binding, filtering, grouping, UI customization, accessibility, and more.
You can bind data from a variety of data sources, such as an array of primitive data, JSON data collections, or remote data sources using different kinds of adaptors such as OData, OData V4, URL, JSON, and Web API. Data binding uses our data manager to manage data and also has customization options for data requests and processing.
