Hello, Mathieu,

Thank you for your feedback and suggestion to add a warning in Kendo UI documentation. I will communicate with my managers.

Meantime, I have come across another solution that you could be interested to check.

As you could see in the dojo example you could use the dataBinding event handler of the Grid and check whether the dataSource has a filter and the action type is "add". If the new items have empty properties - remove them:

dataBinding: function(e) {
	var grid = $("#grid").data("kendoGrid");
        var ds = grid.dataSource;
         var filter = ds.filter();         
         if (filter && e.action === "add") {
             var items = e.items;	
             $.each(items, function(index, value) {
                  var isEmpty = Object.values(value).some(x => (x === null || x === ''));
                   if (isEmpty) {
                     ds.remove(value);
                   }
                 });
                 e.preventDefault();
            }
    }

Hello Mathieu,

Thank you for helping us to improve our product.

In the provided example when a filter is applied the expected behavior is the items that meet the filter criteria to be shown. For instance, if the Unit Price is filtered to display items not equal to 18 then you can notice that a new row for a new record is available, but If the criteria are set to equal then there is no available new row because the rule is not met.

To apply the specific filter behavior you are looking for I would suggest referring to the following article:

https://docs.telerik.com/kendo-ui/knowledge-base/use-filtering-with-dynamic-default-values

If you think that the behavior could be added as a valuable addition out-of-the-box I could convert this thread to a feature request.

I am looking forward to your answer.
