Summary0001814: JvDBDateTimePicker and JvDBDBSpinEdit edit when readonly
DescriptionIf you display a ReadOnly DataSet in either of these controls then the displayed text value can still be changed. The actual field value remains the same, just the display is updated.

From memory, I think other JvDB controls have the same problem.
Additional InformationThe cursor keys, number keys and scroll buttons all change the display value.

I traced this through JvDBDateTimePicker and observed that:

* FDataLink.Edit does recognize that the DataSet is ReadOnly and prevents the dataset being put in edit mode.

* The text value is unchanged at the end of the KeyDown event in JvDBDateTimePicker but is changed by the time CNNotify gets a message in JvDBDateTimePicker - but I was unable to identify exactly where the new text value is set (SetDate is apparently bypassed).
TagsNo tags attached.

Okay, this problem is understood and being worked on. The problem is the same as 0001874 - as anonymous said, so I'll close this one and report progress in 0001874.
