The grid supports two types of selection that can be set by using the selectionSettings.type.They are:

  • Single - The Single value is set by default. Allows you to select only a single row or cell or column.
  • Multiple - Allows you to select multiple rows or cells or columns. To perform the multi-selection, press and hold CTRL key and click the desired rows or cells or columns. To select range of rows or cells or columns, press and hold the SHIFT key and click the rows or cells or columns.
