Restrict the user to input negative integer for column of number data type

Using igx-data grid.

Scenario: For a particular column of number data type, i want to restrict the user to input any negative integer. User can only input positive integer.

I have used (keydown) event to write the validation but it is not working.

Please hep!!

Thanks in advance.

Hello Shobhana Suara,

How about this?

onKeydown(evt: KeyboardEvent, editValue: number) {
 console.log(evt);
  if (evt.keyCode == 189){
    return false;
  }
}

Could you give it a try to see whether this works well?

Hello Noriko,

I tried this piece of code already, it is not restricting the -ve(negative) sign. i have posted the stackbliz above please try in that sample.

I have used this code and it worked. return (event.charCode == 8 || event.charCode == 0) ? null : event.charCode >= 46 && event.charCode <= 57 && event.charCode != 47

Hello,

Thank you for the update.

I'm glad to know that you now have a code which works well.
