Please let me know if it is possible.

Hi Ryosei, 
 
Thank you for contacting Syncfusion support 
 
By using taskbarediting event we can restrict the duration update on resizing. We can set args.cancel as true when taskbarEditAction is LeftResizing or RightResizing. 
We can also hide taskbar resizing element by over-riding the CSS. 
 
Please find the below code example. 
 
<style> 
      .e-gantt-chart .e-taskbar-right-resizer.e-icon.e-right-resize-gripper, 
      .e-gantt-chart .e-taskbar-left-resizer.e-icon.e-left-resize-gripper 
      { 
        display: none; 
      } 
</style> 
        export class Editing extends SampleBase { 
            //... 
            taskbarEditing(args) { 
                if (args.taskBarEditAction == "LeftResizing" || args.taskBarEditAction == "RightResizing") { 
                    args.cancel = true 
                } 
            } 
            render() { 
                return (<div className='control-pane'> 
                 <GanttComponent id='Editing' dataSource={editingData} 
                            taskbarEditing={this.taskbarEditing.bind(this)}> 
                        //... 
                        </GanttComponent> 
                </div>); 
            } 
        } 
 
For your convenience we have prepared a sample. Please find the below sample link.  
 
 
Could you please check the above sample and get back to us if you need further assistance on this? 
 
 
Regards,

Thank you for quick response and sample code in detail.

Could you tell me class name to hide Connector point as well?

Hi Ryosei, 
 
Using ‘e-left-connectorpoint-outer-div’ and ‘e-right-connectorpoint-outer-div’ we can hide the connector point in Gantt taskbar. 
Please find the code example below: 
<style>       
      .e-gantt-chart .e-left-connectorpoint-outer-div, 
      .e-gantt-chart .e-right-connectorpoint-outer-div 
      { 
        display: none !important; 
      } 
</style> 
We have also prepared the sample based on this. Please find the sample from below location 
 
Please let us know if you need further assistance on this. 
Regards, 
Jone sherine P S
