I have created a custom field type and it's working good.
Here is the screenshot of how its looks in core database. All i filled in for template field type Template is Assembly and Class fields.
Here is the screenshot of sitecore's default date field type.
Like you see the difference, i am not using "Control" field for my custom field type and sitecore default field is not using Assembly and Class fields.
So, my questions are
- what's the use of "Control" Field?
- How sitecore default date field working with out "Assembly" and "Class" fields?
