Need help with Iron Python script for validation on input box in spotfire

Shaibaz Antule

Recommended Posts


I have created an input box for showing only entered no. of days data into the report. The report holds data only for last 14 days from the current date.

But, currently when user is entering a value more than 14 in the input box, it is still showing the data in the report. I want to give a validation on this input box.

If user enters value >14 or =DateAdd('day',-${NumberOfDays},DateTimeNow())

Also, attached is the snapshot for the input box created.


Please help if this is possible.

Thank you!

You can attach a IronPython script to the document Property "NumberOfDays" which validates the input value and executed when ever the document property changes.

You can add a script to the property as follows,

Goto Edit - Document Properties - properties tab- select the document property- on the right select script - select the radio button "execute the script selected below" and add the below script


import clr

import System


from System.Windows.Forms import MessageBox




if days14:

Document.Properties["NumberOfDays"]=0 ;

MessageBox.Show("Enter a valid value between 0 and 14")

I am getting this error when I save it as library item and open weblink.

Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application.

How to avoid this error
