DataGrid for DevExtreme - How to show/hide or enable/disable Edit Form items based on another item's value

This example demonstrates how to implement the following scenarios in DataGrid:

• Hide the Home Address form item if the AddressRequired value is false.
• Disable the LastName item editor if the FirstName form item value is empty.

Implementation Details

• Define the setCellValue callback function for the "AddressRequired" and "FirstName" columns to re-render items after an editor value is changed.

• Handle the customizeItem form event.

• In the event handler, call the getRowIndexByKey and cellValue methods to obtain current editor values. Assign the value obtained from the cellValue method to the item's visible property.

• In the onEditorPreparing function, change the disabled option of the required form item editor.
