Bind to Data

You can bind a cell range or table in a worksheet to a data source or use a cell range as a data source for any DevExpress or third-party data-aware UI control (Data Grid, Chart Control, etc.).

Our .NET Spreadsheet API fully supports data export and import. You can import data to worksheet cells from arrays, lists, and data tables – and yes, you can export a cell range to a DataTable.

Filter, Sort, Group, and Search

Just like Microsoft Excel, DevExpress Spreadsheet API includes an AutoFilter - designed to filter data against column values and to display only the rows that meet specific criteria.

As you would expect, our Spreadsheet API supports grouping (outlines) and sorting against an unlimited number of columns. You can sort data by text (alphabetically, according to the current culture), numbers, dates, and time.

And of course, you can search within a worksheet, specify whether the operation should be case-sensitive, and search using wildcard characters.
