What is the use of FilterUIHintAttribute and give example

You could use the AdditionalMetadata attribute:

[UIHint("DateTime")] [AdditionalMetadata("foo", "bar")] public DateTime Date { get; set; }

and in the template:

@ViewData.ModelMetadata.AdditionalValues["foo"]

so if you wanted to pass an url:

[UIHint("DateTime")] [AdditionalMetadata("controller", "somecontroller")] [AdditionalMetadata("action", "someaction")] [AdditionalMetadata("property", "someproperty")] public DateTime Date { get; set; }

and in your template:

@{ var values = ViewData.ModelMetadata.AdditionalValues; }  <script type="text/javascript"> $('.auto').autocomplete({     source: function (request, response) {         $.ajax({             url: '@Url.Action((string)values["action"], (string)values["controller"])',             dataType: "json",             data: {                 filter: request.term             },             success: function (data) {                 response(                     $.map(eval(data), function (item) { return {                             label: item['@values["property"]'] } }) ); } }); } }); script>
