Numeric editor to allow only positive numbers in kendo react grid

Hello, Seenu,

This can be done in two ways:

1) Using a custom editor cell where the developer can render a custom NumericTextBox with a min property set to 0.

2) During the onItemChange event, do not update the state if the value is less than 1:

  const itemChange = event => {
    let field = event.field || '';
    if(field === 'UnitsInStock' && event.value < 0) {
      return;
    }

Please have in mind that the NumericTextBox allows entering invalid values and it will return to the valid one on blur. This means that in both cases the user will be able to enter negative values, but they will be set back to 0 on blur.

Regards,
Stefan
