RangeValidator Minimum Date can not be 01.01.0001

[Johannes Hammersen]

Hi,
when I try to set the Minimum Date on a RangeValidator to 01.01.0001 I get
an error, that 01.01.0001 can not be converted to a date.
But the DateType can be 01.01.0001. Convert.ToDateTime("01.01.0001") works.
So why can't I set the Minimum of the RangeValidator to that Date?

I have the same Problem with the Maximun Value. If I try to set that let's
say to the 31th December 9999 it will give me an error.

You can reproduce this error if you put an RangeValidator on a WebForm, set
it's type to Date an put 01.01.0001 as minimum value.

What am I doing wrong? Or is this a bug, and if yes does anyone know a
workaround?

Thanks for any help

Johannes,

From the help file for RangeValidator.MaximumValue:

"Note If you specify ValidationDataType.Date for the
BaseCompareValidator.Type property without programmatically setting
the culture for the application, you should use a culture-neutral
format, such as YYYY/MM/DD, for the MaximumValue and MinimumValue
properties. Otherwise, the date may not be interpreted correctly."

Ah,

thanks that helps!
I thought I would just use the maschines settings like convert.to does.

Thank you
