Hey there,
As per the requirement, I would like to restrict the user from entering certain characters like ‘”‘,’/’ etc. in the column filter.

Could you propose a solution for this?

Hello shivam,

If you are using filter row (showfilterrow: true), you can use the createfilterwidget callback to achieve your requirement. Here is how:
