Selection provides an interactive support to highlight the row, cell or column that you select. Selection can be done through simple Mouse down or Keyboard interaction. To enable selection, set e-allow-selection as true.

Types of Selection

There are two types of selections available in grid. They are

1. Single
2. Multiple

Single Selection

Single selection is an interactive support to select a specific row, cell or column in grid by mouse or keyboard interactions. To enable single selection, set e-selection-type property as single and also set e-allow-selection property as true.

Multiple Selections

Multiple selections is an interactive support to select a group of rows, cells or columns in grid by mouse or keyboard interactions. To enable multiple selections, set e-selection-type property as multiple and also set e-allow-selection property as true.

Row Selection

Row selection is enabled by setting selectionMode property of e-selection-settings as row. For random row selection, press “Ctrl + mouse left” click and for continuous row selection press “Shift + mouse left” click on the grid rows. To unselect selected rows, press “Ctrl + mouse left” click on selected row.
