[Solved] ArgumentOutOfRangeException when using MinValue

[Erez]

Hi,

I have two bindable properties in my view-model: DateBegin and DateEnd. Both are of type DateTime.

Using the RadTimePicker, if binding both MaxValue (DateEnd) and MinValue(DateBegin) I get the following exception: 

System.ArgumentOutOfRangeException: Hour, Minute, and Second parameters describe an un-representable DateTime.
   at System.DateTime.TimeToTicks(Int32 hour, Int32 minute, Int32 second)
   at System.DateTime..ctor(Int32 year, Int32 month, Int32 day, Int32 hour, Int32 minute, Int32 second)
   at Telerik.UI.Xaml.Controls.Input.DateTimePickers.DateTimeList.GetDateTimeAt(Int32 logicalIndex)
   at Telerik.UI.Xaml.Controls.Input.DateTimePickers.DateTimeList.IsItemEnabled(Int32 logicalIndex)
   at Telerik.UI.X

DateEnd = DateTime.Now
DateBegin = DateEnd.AddHours(-24)

If I set only either one of these properties, the control works without exception but will, of-course, default to a 6 hours window.

Is it a bug or am I doing something wrong?

Thank you,
Erez

Hello Erez,

Thank you for contacting us.

Unfortunately, we could not reproduce this error on our side. I have attached a sample project that I made according to the described scenario and no exception is thrown. Could you please modify it to reproduce the error.

Another thing, the RadTimePicker control uses only the time part of the DateTime structure, this means that it sees the DateTime.Now and DateTime.Now.AddHours(-24) as the same time and this is why it won't allow the user to pick any time. I have commented the lines of code in the project that could fix your problem.

Please, let us know if this works for you.
