I need to validate all fields in my application before submitting data

HI Sachin,

 

Here what i need to do validate all fields again then the data will save to DB.

 

 already we applied validations but after that also i need to validate all fields using exsting method.

 

So that I am created one ValidateController and then how to map existing methods.

 

what i understand here is the data is coming from controller to view then again same data need to  transfer view to controller. this is i am confused how to map those method.

 

regards, 

use ModelState.Isvalid()

 

and apply attributes like Required on Model Properties. 

if you are using

1.Web Forms

then use validation controls (on client side) :- thus client page got validated.

In Code behind use 

 hence, server side validation.

2.MVC

Implement data annotaions on model properties like

 use this in client side

 In server side use

 In this way , you can double assure that your database is getting what it needs only.

HI amit,

 

  The value of the username request parameter is copied into the application response.

 

 So both getting same value

 

 So i need implemented vallidations into all fields, please give me suggisions.

 

Thanks, 

Can you share the reason for validating the same thing multiple times?

 

You can validate in 2 sections
