If this property is set to true, it allows a user to select all rows at once by pressing Ctrl + A or clicking the check box in the selection column's header. The "Select All" check box also allows a user to deselect all rows. The select all functionality allows selecting/deselecting only those rows that meet filtering conditions if a filter is applied.

If this property is set to false, it disables the select all functionality. In this case, the check box clears selection and is hidden if no rows are selected.

The following selection modes are available in the UI component:

• Single
  Only one row can be in the selected state at a time.

• Multiple
  Several rows can be in the selected state at a time.

Use the SelectionMode enum to specify this property when the UI component is used as an ASP.NET MVC 5 Control or a DevExtreme-Based ASP.NET Core Control. This enum accepts the following values: None, Single, and Multiple.
