The WinForms multicolumn listbox control (GridListControl) allows users to select single or multiple items from the list of items. Its rich feature set includes selection, headers, different column types, appearance customization and more.
Data binding helps in populating the grid list control with large amounts of data, which allows the system to acquire data from the Data Source Object (DSO).
The grid list control can be coupled to a combo box base control by using the list control property of combo box base class. The combo box base is an advanced control provided by Syncfusion that essentially separates the edit portion from the drop-down portion. It displays grid list control as a drop-down, i.e. users can drop the grid list control in the drop-down area to get a multicolumn drop-down effect.
The grid list control lets you change the style settings of the control, such as the background color, transparent background, background image, and header background color. You can readily access the grid instance inside the grid list and fully utilize the grid API to customize it even better.
