If you don't want users to edit data within the FlexGrid, disable editing by setting the datagrid to read-only. This prevents FlexGrid from going into edit mode when a user begins typing or double-clicks a cell.
Although FlexGrid provides Excel-like, in-cell editing, some users may want to customize the editing behavior. The DataGrid allows you to include buttons in a column, which will then send the row into edit mode when clicked.
IME, or Input Method Editor, allows data, such as keyboard strokes or mouse movements, to be received as input by FlexGrid. IME is obligatory for languages such as Japanese, Chinese, and Korean.
