ASP.NET Custom Web Controls
Binds to IHierarchicalDataSource
Our custom ASP.NET DropDownList when bound to any IHierarchicalDataSource (for example: SiteMapDataSource, XmlDataSource) fully preserves hierarchical nature of data. It’s a great alternative for more space consuming menus or tree controls especially given the fact that drop-down list metaphor is widely used and loved among GUI developers and users.
Three Modes of Computing Values
To serve all your needs for reading drop-down list values, XmlDropDownList is equipped with three modes: DataTextField, DataValueField and NodePath. While the first two closely resemble 'SelectedText' and 'SelectedValue', the latter returns valid XPath query qualifying the node in hierarchical structure.
Customizable Nesting Prefix
Prefix responsible for visual nesting of hierarchical nodes can be customized. Default value simulates tree-like structure.
Extends Standard DropDownList
Small change from '<asp:DropDownList ..> ' to '<'cc:XmlDropDownList ..>' makes upgrade from standard DropDownList control a snap. There is no learning curve to use our control for those who already are comfortable working with standard asp.net DropDownList control.
Works with Microsoft Ajax.
Cross Browser Support
Supports all today’s major browsers on Windows, Mac and Linux platforms.
