How to allow only numbers in ListGridField ?

[preeti_kanyal]

Hi,

I dynamically created ListGrid in smart GWT. All the ListGridFields are accepting any character but I want to allow only numbers in some ListGridField.
I tried :-
1) ListGridField gridField = new ListGridField("columnName", "columnTitle");
gridField.setType(ListGridFieldType.INTEGER);
2 ) ListGridField gridField = new ListGridField("columnName", "columnTitle");
IntegerRangeValidator integerRangeValidator = new IntegerRangeValidator();
integerRangeValidator.setMin(0);
integerRangeValidator.setMax(99);
gridField.setValidators(integerRangeValidator);
But, still it allow any character.

Please reply if you know how could I fixed this ?

The type being set to Integer, and the integer range validator will ensure that when validation occurs, invalid (non numeric) values are rejected. This is definitely a good idea to avoid invalid values being submitted to the server (or accepted on the server from a request that doesn't go through client side validation for some reason).
*Edit: Note that the server validation will only be respected for validators applied to the dataSource configuration (ds.xml file) - as the server of course doesn't see the ListGridField definition directly.

If you also want to limit the user input, you can use a mask or keypress filter
