Any update guys....

[Manoj Chaurasia]

it was an error you suppose to catch errors

FIXED:

import clr

clr.AddReference("System.Windows.Forms")

from System.Windows.Forms import MessageBox

from Spotfire.Dxp.Application.Visuals import VisualContent

from Spotfire.Dxp.Application.Visuals import TablePlot

from Spotfire.Dxp.Application import *

viz=emp.As[VisualContent]()

if columns==columnname :

try:

viz.TableColumns.Add(dataTable.Columns[columns])

except:

MessageBox.Show("Column alredy added")

Thanks :)

thats what i was looking for changing columns based on property value using SCRIPT :)

Could you please also show how can we remove dynamically added columns in the table and add new ones.

 

My table has more than 100 columns.I could add columns dynamically but if I dont want to show any column then how show I remove it dynamically and select another column instead

 

Any help is appreciated.Thanks!
