Kindly make a video how to make model validation in partial view in asp.net core, It's my humble request.

[@SaurabhKumar-om2gz]

I could not able to understand how nullable field resolve the int and string compatibility. Can someone please clear this ?Thanks

[@bhagwatshahi7244]

Thanks sir for the tutorial..i have a doubt when you post the data without filling all the required fields, error message is getting displayed that is fine but how does others fields remember their value since you are not passing the model back to the view...

How to override te default validation for types ? When i use double and that I try to write letters in the input i get the default "the value "hdhsk" is not valid", but how can I override this one ? I finded a way with using ModelState.Clear() before using ModelState.AddErrorMessage(...) with simple one field forms but with bigger one it's not so easy...

[@maximilianponiatowski4745]

With int type I can specify type="number" in view input to block the possibility of using letters but this dosn't allow decimals or doubles...

[@wahyumaulanaakbar7920]

i have one question sir, do we need validation attributes on the data (not the model) as well? and can we create database-level validation as well? Thank you so much been following this tutorial

[@saikrishnak6872]

If I want apply the data annotation validations to be fired on the view load for the first time, how can it be achieved?

[@WebGentle]

What do you mean by "view load for the first time"? . Give some more details.

[@vangpallysrinivas6982]

hi sir modelState.Isvalid is allways false how to resolve it

[@amannayyar5124]

Make sure there are no null entries in the model for non null properties. Make Category and Language as Nullable then issue will be resolved. public string? Category { get; set; } public string? Language { get; set; }

[@aayushpatel3152]

Jquery-validate and Jquery-validation-unobtrusive client-side libraries should be installed as well otherwise it won't work
