so, I just implement the auto scheduling feature, but when I turn of auto scheduling of specific task, I got this error when trying to move or resize task
also, how to update the content of the grid, e.g when task auto schedule is off, the icon on the first column of the grid should be thumb-tack, and when auto scheduling is on, the icon should be arrow
As for changing content in the grid, you can add icons based on CSS class which is added dinamically by grid_row_class template. Please, check example (new color is added instead of icon): docs.dhtmlx.com/gantt/snippet/f108af38
