Hi Rohit,
Thanks for using Syncfusion products,
In order to disable the scrollbar, you can use the HScrollBehavior and VScrollBehavior property. Please refer the below code snippet
Code Snippet:
this.gridControl1.HScrollBehavior = Syncfusion.Windows.Forms.Grid.GridScrollbarMode.Disabled;
this.gridControl1.VScrollBehavior = Syncfusion.Windows.Forms.Grid.GridScrollbarMode.Disabled;
Regards,
