Hi Sravan,
Thanks for using Syncfusion products.
We would like to let you know that we are having an API called “autoCheck” which specifies automatic checking of parent/child can be enabled or disabled. If this property is disabled, then the Parent or Child node Checkbox will not get affected on checking a particular node. By default, the value of autoCheck property is true. For your convenience we have prepared the sample based on your requirement. Please find the sample from the following location.
Sample Location: Sample
You can also refer the following class reference link for JavaScript. Since our ASP.NET MVC components are created as wrapper for the JavaScript components the properties, methods and events will be same for MVC components.
