Which types use a FileNameEditor in a PropertyGrid?

Question

I need to change the editor for a property attached to a .net PropertyGrid, but I cannot set the Editor attribute of that property, because the property was generated by a tool, including all attributes.

The desired editor is

System.Windows.Forms.Design.FileNameEditor

I can find many tutorials on the web to assign this editor to string properties by setting the editor attribute, but I cannot set the editor attribute in this case. However, I can advise the code generation tool to behave such that the string property which I want to be edited with the FileNameEditor becomes converted to another property with different type.

In order to do so, I would need to know which type is edited by the FileNameEditor as default. I didn't find any list on the web which would tell me for a given editor which types employ this editor automatically when displayed in a PropertyGrid.

Answer 1

This editor works with strings only and is not attached automatically to any other type.

Answer 2

According to Reflector, it's used only for 2 properties :

• SqlConnectionStringBuilder.AttachDBFileName
• OleDbConnectionStringBuilder.FileName

Answer 3

OK, thanks for your help.
