Hi Georgi,
Ignoring everything I said means we disagree.
As I said, this is not a feature request, this is clearly a bug involving IsEditable property.
You are suggesting to ignore the bug, and consider a new feature. If there is an IsEditable property, why would you need a ReadOnly property as well? How would you explain the difference in them?
Would you write in the documentation that IsEditable makes the control semi-readonly?
You do realize that currently the documentation is completely wrong: "Gets or sets the value indicating whether the control is editable or not". - It is editable. always.
