I have a sub that checks the minimum value of a textbox

Public Sub ValidCheck()

        rvCompDateCheck.MinimumValue = DateTime.Today.AddDays(-7).ToShortDateString()
        rvCompDateCheck.MaximumValue = DateTime.Today.ToShortDateString()


    End Sub

Open in new window



It worked until yesterday(31/10/2016)

Now today (01/11/2016)  

I get the below error

The MaximumValue 01/11/2016 cannot be less than the MinimumValue 25/10/2016 of rvCompDateCheck.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.Web.HttpException: The MaximumValue 01/11/2016 cannot be less than the MinimumValue 25/10/2016 of rvCompDateCheck.

I've tried this but still get the same error

 
  Public Sub ValidCheck()

        System.Threading.Thread.CurrentThread.CurrentCulture = New System.Globalization.CultureInfo("en-GB", True)
        System.Threading.Thread.CurrentThread.CurrentUICulture = New System.Globalization.CultureInfo("en-GB", True)


        Dim Minval As Date
        Dim Maxval As Date

        Minval = DateTime.Today.AddDays(-7)

        Maxval = DateTime.Today


        rvCompDateCheck.MinimumValue = Minval
        rvCompDateCheck.MaximumValue = Maxval




    End Sub

Open in new window

Try..

Dim x As DateTime = DateTime.Now
rvCompDateCheck.MaximumValue = x.ToShortDateString()

x = now.AddDays(-7)
rvCompDateCheck.MinimumValue = x.ToShortDateString()

Looks like a format issue, try below if above is not working..

DateTime.Today.ToString("yyyyMMdd")

Public Sub ValidCheck()

        rvCompDateCheck.MinimumValue = DateTime.Today.AddDays(-7).ToString("yyyyMMdd")
        rvCompDateCheck.MaximumValue = DateTime.Today.ToString("yyyyMMdd")

End Sub

Thanks

the above works...almost.

No error anymore but it is not picking up on the fact that

31/10/2016  is less than 01/11/2016

It needs to be UK format I think.

Try.. Do you know the format in terms of mm/dd/yyyy  or dd/mm/yyyy or mmmm d yyyy?

CultureInfo ci = new CultureInfo("en-GB");
rvCompDateCheck.MaximumValue = DateTime.Today.ToString("d", ci)

OR

rvCompDateCheck.MinimumValue = DateTime.Today.AddDays(-7).ToString("dd/mm/yyyy")
rvCompDateCheck.MaximumValue = DateTime.Today.ToString("dd/mm/yyyy")


OR

rvCompDateCheck.MinimumValue = DateTime.Today.AddDays(-7).ToString("mmmm d yyyy")
rvCompDateCheck.MaximumValue = DateTime.Today.ToString("mmmm d yyyy")
