DataSourceRequest parameters not validated

[gyankov]

Bug report

Currently the DataSourceRequestModelBinder does not validate the parameters when casting their values. Thus, when an invalid value is supplied, an exception is thrown.

Reproduction of the problem

Send a request with pageSize parameter that exceeds the maximum int value.

Current behavior

Value was either too large or too small for an Int32 is thrown.

Expected/desired behavior

No exception should be thrown.

Environment

• Kendo UI version: 202x.r.ddd
• jQuery version: x.y
• Browser: [all | Chrome XX | Firefox XX | IE XX | Safari XX | Mobile Chrome XX | Android X.X Web Browser | iOS XX Safari | iOS XX UIWebView | iOS XX WKWebView ]

When the filter operator is invalid, for example "https://XXX?filter=active~equals~true", the DataSourceRequest query string parser causes System.NullReferenceException, which is not informative enough:

System.NullReferenceException: Object reference not set to an instance of an object. at Kendo.Mvc.Infrastructure.Implementation.FilterNodeVisitor.Visit(PropertyNode propertyNode)
