Immutable mode in JavaScript Treegrid control

18 Nov 20181 minute to read

The immutable mode optimizes the Tree Grid re-rendering performance by using the object reference and deep compare concept. When performing the Tree Grid actions, it will only re-render the modified or newly added rows and prevent the re-rendering of the unchanged rows.

To enable this feature, you have to set the enableImmutableMode property as true.

  • This feature uses the primary key value for data comparison. So, you need to provide the isPrimaryKey column.

Limitations

The following features are not supported in the immutable mode:

  • Frozen rows and columns
  • Row Template
  • Detail Template
  • Column reorder
  • Virtualization
