task dom change

[raining]

when source data change，task dom is update or init？

[tasnim]

Could you please explain with some images showing us what exactly you want to achieve?

[raining]

our data is very large，when source data change，all task update is very waste time，If source data change，dom needn't init， I want to control only update task when task in the visible region。

Yeah Sure.

Please check the code below to achieve it:

project : {
	taskStore : {
		listeners : {
			beforeUpdate() {
				console.log('update');
			}
		}
	}
}

I try it, it only work when drag task.when source data change,it not trigger

[tasnim]

Then, use this: https://bryntum.com/docs/taskboard/api/TaskBoard/store/TaskStore#event-change

Here is an example :

project : {
	taskStore : {
		listeners : {
			change() {
				console.log('change');
			}
		}
	}
}
