Hi I’m trying to update task property before rendering, the main reason for doing this is to avoid looping over entire task data to update common property. I only want to update visible task data, I tried to achive this using onGanttScroll and visible Task ID which worked but not neatly, another way I found is by modifying task object in onBeforeTaskDisplay event which most time leads to infinity re-rendering, is there any way I can achieve visible task update?
Hello Vyshnav,
There are 2 commands that can be used to repaint a task: updateTask and refreshTask. The first method will trigger the internal events, and that includes sending the data to the server-side:

The second method only repaints the task:

If you modify a task property in the onBeforeTaskDisplay event, you need to make sure that you don’t call any of these methods.
Here are examples:

Also, it is not expected to modify a task in the onBeforeTaskDisplay event handler.
Could you clarify why you need to modify a task before rendering the data?
