DateTimePicker giving Exception with custom format

I'm receiving the following exception when I try to use a custom format in my DateTimePicker :

"The string was not recognized as a valid DateTime."

I'm using the following snippet :

  dtpSystemAdjustmentDate.Format = DateTimePickerFormat.Custom;
  dtpSystemAdjustmentDate.CustomFormat = "mm.dd.yyyy hh:mm:ss";

I've found documentation on the Microsoft help pages : http://msdn.microsoft.com/en-us/library/aa983603%28v=vs.71%29.aspx

I Tried this snippet :

    // C#
    dateTimePicker1.CustomFormat = "'Today is:' hh:mm:ss dddd MMMM dd, yyyy";

I'm receiving also an exception, complaining about "Today" being a keyword that is not recognized.

I suspect something related to culture (my current Culture is fr-CH) but I can't find a way to make it work... Any idea ?

Solution

  • My problem wasn't related to .Net or C#.

    I tried a blank project, using the same code and it worked.

    I was inheriting a subclass of Form that is in charge of translating the Controls within the form. Unfortunately, something is messing up the text content of my DateTimePicker.

    My previous lines were correct.
