The MultiColumnComboBox is a component that displays large sets of data in a grid-like table providing additional data values for each individual item. The control comes with a lot of features and functionalities such as filtering, virtualization, grouping, templates, cascading MultiColumnComboBoxes and more, to ensure execution of all possible scenarios.
Virtualization is another feature that the MultiColumnComboBox supports. It allows you to display a fixed number of items from a large set of data and scroll to see the rest of the existing rows in the same format. Virtualization helps you implement heavy-data scenarios seamlessly. Configure the desired view and number of items to be shown at once and set the specific width of your grid columns for smoother user experience.
