GridView Row Level Editing and Row Validation

1. The RowValidating and RowValidated events do not fire when expected.
You have these events set to fire when the user changes rows. What happens when there is only one row in the grid? Expected behavior is to fire when the Row loses focus, which should happen when a user clicks anywhere outside the row, including whitespace or other controls on the form.

2. The data is saved before row validation is complete.
What is the point of having row-level validation if the values have already been saved to the databound object? Absolutely nothing should be saved until ALL validation is complete.

3. The user is locked down and unable to escape/cancel the edit if the row validation actually gets called and fails.
This is extremely poor design. You cannot expect a user to be able to fix the issue every time. Sometimes they will need to start over, especially if there is a large amount of data. Instead, you lock them down and force them into making changes they may not want to commit to.

These problems have been around for years, but nobody has taken the time to address them despite promises. Even worse, the links to the Feature Requests in these threads no longer work and Telerik has changed their stance from admitting the problems to claiming that these are "desired behaviors" and "features". Stop calling these behaviors features, they are most certainly not.

DateTime Column displayed as LocalTime?

Hello,

We have an application with SQL Server running in one location and then clients in different timezones using that data. All datetimes are stored as UTC values. For display we want them in local date/time. How do we do that in GridView?

For example:
A grid showing a list of events with an updated_date column. We want those event dates/times as local time. Can .formatstring be used to somehow set ToLocalTime()?

Thanks,
Paul

Print with Sunday as first day

My application is a scheduler for customers that use a normal US calendar with Sunday as the first day of the week. The RadScheduler displays this way but the printouts do not. When I print a weekly calendar, I get 2 pages, one with the previous week, with Sunday as the last day, and one for the current week with Monday as the first day. Is there a workaround for this?
