Spotfire-如何添加重新加载按钮

Question

How to add a button and whenever user clicks on the button the data reloads.

Also the user should know when the data gets refreshed.

Answer 1

You could use this python script, as found here .

from System.Collections.Generic import List, Dictionary 
from Spotfire.Dxp.Data import DataTable 
from System.Collections import ArrayList

#Refreshing a single Data table:
dataTable.Refresh() // where dataTable is a script parameter of type DataTable

#Refreshing multiple tables:
#Note that more than one table can be added to the List object.
tables = ArrayList()
tables.Add(Document.Data.Tables["DataTable1"]) 
tables.Add(Document.Data.Tables["DataTable2"]) 
Document.Data.Tables.Refresh(tables)
#As such DataTableCollection.Refresh Method refreshes the given tables in dependency order.
#OR
Document.Data.Tables.RefreshAsync(tables)
#And DataTableCollection.RefreshAsync Method (IEnumerable< DataTable> ) refreshes the given tables in dependency order. 
#Tables that have asynchronous refresh (i.e. Data On Demand and Data Functions) and tables that depend on them will be refreshed 
#in later transactions.

# Another possible option:

Tbls = List[DataTable]() 
Tbls.Add(Document.Data.Tables["DataTable1"]) 
Tbls.Add(Document.Data.Tables["DataTable2"]) 
for i in Tbls:
 Document.Data.Tables.Refresh([i])

In order to let the user know when the data was refreshed, just set a document property with the current date/time and surface that document property in a text area. When the script above is run, the date/time will update.

Also, have a look at their Python API page located here (for 7.6, but the newer 7.12 API can be found as well). While it is organized in a slightly frustrating way, you can get a feel for methods and classes you can call in your script to do all sorts of things programmatically.
