Hi Michal,
Thanks for contacting Syncfusion support.
By setting the “showGridCellTooltip” as false we can hide the tooltip in Grid part.
In Gantt chart we can hide both taskbar tooltip and drag tooltip by setting the “enableTaskbarTooltip” as false and “enableTaskbarDragTooltip” as false,
Please refer the following code snippet:
<div id="gantt"></div>
<script type="text/javascript">
$("#gantt").ejGantt( {
dataSource: projectData,
//…
showGridCellTooltip: false,
enableTaskbarTooltip: false,
enableTaskbarDragTooltip: false,
});
</script>
We have also prepared a sample for your reference. Please find the sample in the following URL.
