Hi Puthirak,
Thanks for using Syncfusion products.
We have another property CellType. We can disable the selection and edit option and it enables the navigation by setting the value as "Static" in GridControl. Use the below code
grid.Model.TableStyle.CellType = "Static";
Please download the sample from the below location.
