Asp net validating datetime
NET MVC, because the type you specify will determine what “template” MVC uses.
Thus, for the Date Time property if you create a partial in Views/[loc]/Editor Templates/(or cshtml for razor), that view will be used to render the property when using any of the Html. One thing that the Data Type() validation attribute does not do is any actual validation.
There is a little bit of conventions magic going on here, but the distilled version is that we are defining a “date” validation type, which will be included as html5 data-* attributes (specifically data-val-date).
Then jquery.validate.unobtrusive takes this attribute and basically passes it along to jquery.validate, which knows how to handle date validation. First make sure to reference the jquery, jquery.vaidate and jquery.validate.unobtrusive scripts that you will need for client validation. Here data-val-required was added automatically because Date Time is non-nullable, and data-val-date was added by our validation adapter.
Since Data Type() doesn’t validate, that leaves us with two options: (1) Create our own attributes for each datatype to validate, like [Date], or (2) add validation into the Data Type attribute directly.
In this post, I will show you how to hookup client-side validation to the existing Data Type() attribute for a desired type. NET MVC project that allows us to create a new Data Type Entity and hookup automatic client-side date validation using the suggested “out-of-the-box” jquery.validate bits that are included with ASP. For simplicity I’m going to focus on the only Date Time field, but the concept is generally the same for any other Data Type. Since we are extending Data Annotations we can use the subclass of Model Validator called Data Annotations Model Validator.
Here are a few quick examples: This attribute comes in handy when using ASP.
Data Annotations namespace contains a validation attribute called Data Type Attribute, which takes an enum specifying what data type the given property conforms to.
One of the most common elements of Web pages is a form in which the user can input data that is posted back to the server.Keep an eye on this blog and subscribe to my twitter feed (@srkirkland) if you are interested for announcements. I imagine it would also be possible to hook up client-side validation automatically based on the fact that the model property is a Date Time, skipping the attribute altogether.Maybe by building the unobtrusive validation html attributes into the Date Time editor template?So starting from there and implementing the required constructor, we get: Get Client Validation Rules().Adding logic to the server-side Validate() method is pretty straightforward, and for this post I’m going to focus on Get Client Validation Rules().
