Question

Facts:

• I have a TabControl with 2 Tabs, Each tab has 2 DateTimePicker.
• In the Load event, I set the value of all the DTPs.
• All DTPs have ShowCheckBoxes set on true AND Checked set on false.
• When I Execute the program, The DTPs in first tab are OK, but when I check the DTPs on second tab, they show current time, not the time I set on the load event.

Why this happen? How can I avoid it?

Answer 1

My ugly workaround to this issue, consists on set active the tab in which the DTP’s reside before changing its values, something like this:

DateTime dat1 = DateTime.Today;
DateTime dat2 = dat1.AddDays(1).AddSeconds(-1);

dtpCreatedStart.Value = dat1;
dtpCreatedEnd.Value = dat2;
tbc.SelectTab(1);
dtpModifiedStart.Value = dat1;
dtpModifiedEnd.Value = dat2;
tbc.SelectTab(0);
