Popup Editors

Although FlexGrid provides efficient, Excel-style editing by default, you may want to customize the editing behavior.

This example shows how you can use the grid to display the data and a custom form to edit the items. The custom form is hosted in a C1 MVC Popup control and contains Wijmo input controls.

Click the pencil glyphs in the row headers to edit the item.
