Then we in the constructor we made a custom method named init() and then we add a definition of that function in which we’re calling another custom function initTable(). The reason why we are making so many custom functions is that it’ll make it easier in the future when we’ll be adding more functionalities like search, edit, add, etc.


Validation is supported in ASP.NET Core by decorating your model object with data annotation validation attributes. Before values are sent to the server, the validation attributes are checked on the client-side. The framework validates request data on both the client and the server.
