Immutable Mode in ASP.NET Core Gantt Chart

The immutable mode optimizes the Gantt re-rendering performance by using object reference comparison and deep equality checks. When performing the Gantt 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.

The following code example shows how to display the immutable mode in the Gantt control.

Limitations

The following features are not supported in the immutable mode:

• Column reorder
• Virtualization
