Use of dependent drop-down in Grid.

[minjah]

I used dialog form for editing and adding a record. My records contain three drop-down one is independent other are dependent on each other. I want to update other dropdown values on select change event and on the initial stage.
I have dropdown value as id from grid data source and drop down data source have values like [itemTypeId : ItemTypeName],

the dependent drop-down data source will be changed by changing the parent dropdown value.
I am using APIbased MVC project without MVC controls.
