How to access row data in custom validator?

Custom validation rules can be set to a column using the validationRules property of the column in grid. But, in certain cases, the user may expect to set validation to a column based on another column value i.e., set conditional validation to a column

Solution

Let us consider a grid column on which we need to perform custom validation considering another column value.

Example

Let us now see in detail how to achieve the above requirement in grid.

  1. Render the Grid control

JS

 

MVC:

 

ASP.NET

 

  1. Using the jQuery serializeArray method, we have fetched the form data. Since the serializeArray method, doesn’t return the values corresponding to disabled elements, we have created a plugin to fetch the disabled elements also from the form elements. 

 

Thus, the form data elements, will be obtained within the custom validator and thus we can perform corresponding actions in the validator.
