Filtering

Documentation

This example demonstrates the DataGrid’s built-in filtering and searching capabilities. The filter row, located under the column headers, allows a user to type any value and select filter operations. With the header filter, which is called by clicking the filter icon in any column header, a user can choose from a set of predefined values. The search panel at the top of the DataGrid allows searching for values in all columns at once.
