Adding New Rows in React Datagrids
Wijmo's React datagrid, FlexGrid, allows you to implement a new row feature without writing code for additional rows.
Add New Row
Adding a blank row to Wijmo's React datagrid, FlexGrid, allows users to add even more rows of data. You can automatically include the blank row at either the top or bottom of the datagrid when you set the grid's allowAddNew property.
