I am trying to write an if statement for two datetimepickers. I have a start date and end date and I do not want the value of the start date to be greater than the end date.
Here is what I have tried but doesn't work:
If dateStart.Value.Date < dateend.Value.Date Then
lblstatus.Text = "Status: Start date must be a date before end date."
Else
End If
Your Operator is wrong .. it should be greater than, not less than :)
If dateStart.Value.Date > dateend.Value.Date Then
lblstatus.Text = "Status: Start date must be a date before end date."
Else
as alternative you can change the .MinDate and .MaxDate properties in the ValueChanged event
Sub init()
AddHandler dateStart.ValueChanged, Sub() dateEnd.MinValue = dateStart.Value
AddHandler dateEnd.ValueChanged, Sub() dateStart.MaxValue = dateEnd.Value
End Sub
lblstatus.Text = dateStart.Value.Date > dateEnd.Value.Date ? "Status: Start date must be a date before end date." : dateStart.Value.Date(Or whatever you want to happen if it is a valid date by your condition check)
>=instead of<in the comparison.
