Thanks Alessio.
Unfortunatly I want to edit this field. There are several types of documents stored in my table for some of them user must enter date of the document precisely (with time) for some of them time part is unimportant. I just want to switch the way the date of a document is edited dependend of document type.

>>>>I have a datetime field in a table. For some users time part of the value is unimportant. Sometimes they need to edit the value in textbox control in exactly the same way as date values (only date without time). As far as I know there is no such property as HideTimePartOfDateTime in textboxcontrol.
