The string "null" is converted to null by the datasource parser

Reproduction of the problem

Defina a dataSource with a model that has a string field. Pass data that has "null" as a value.

Current behavior

The string "null" is converted to null.

Expected/desired behavior

The value should not be converted.

I am experiencing this issue with Dotnet core as well. A user with the last name of Null has their last name not appear in the grid due to this issue.

I am running the latest version 2024.1.319

Hi @christopher-mckain, thank you for your report. Both .Net and jQuery components share the same client-side dataSource component, thus the consistent behavior. I am increasing the priority of this issue.
