Hi,

here you have a code snippet:



<asp:TextBox ID="txt" Runat=server></asp:TextBox>
<asp:RangeValidator ID="validDate" Type=Date MinimumValue="2004-10-10"
MaximumValue="2004-10-11" ControlToValidate="txt" EnableClientScript="true"
ErrorMessage="invalid date" Runat=server Display=Dynamic />
<asp:ValidationSummary Runat=server
EnableClientScript=True></asp:ValidationSummary>
<asp:Button Runat=server ></asp:Button>


Now the dates a set static but to change this to make them dynamic add
something like this to the script section of your code:

validDate.MinimumValue = Now.AddYears(-3)
validDateMaximumValue = Now.AddDays(30)

I haven't tested all of this now but the concepts are these...
Bye

Well that looks good, but can it be globalized?

Date format seem to vary with cultures. So i doubt the hardcoded date format
will
hold when the application should support other cultures.

But you are totally right if globalization is not an issue for the
given product.

Thanks

Wait...I can't use a variable instead so the date doesn't have to be
updated each time in the maximum and minimum value?

Okay...Thanks Cristian...I just needed to wake up. Thanks a lot for the
help! Here is what was changed:

Private Sub Page_Load
validDate.MinimumValue =
CDate(DateTime.Now.AddYears(-3).ToShortDateString)
validDate.MaximumValue =
CDate(DateTime.Now.AddDays(30).ToShortDateString)
End Sub

Have a great day!
