This function is used in Python Scripting.


Takes a dataset and returns a new dataset with the specified rowIndex removed.

Note: Datasets are immutable, which means they cannot be directly modified once created. Instead, this scripting function returns a new dataset with some modification applied, which must be assigned to a variable to be used. See Altering a Dataset.

Client Permission Restrictions

This scripting function has no Client Permission restrictions.


system.dataset.deleteRow(dataset, rowIndex)

  • Parameters

Dataset dataset - The starting dataset. Please be aware that this dataset will not actually be modified (datasets are immutable), but rather will be the starting point for creating a new dataset.

Integer rowIndex - The index (starting at 0) of the row to delete. Will throw an IndexError if out of bounds. The maximum bounds is defined by subtracting one from the number of rows in the dataset. 

  • Returns

Dataset - A new dataset with the specified row removed.

  • Scope

Gateway, Vision Client, Perspective Session

Code Examples
Code Snippet
# This example would remove the selected row from a Vision List component, by re-assigning the List's data property to the new dataset returned by the deleteRow function.
myList = event.source.parent.getComponent("List")
row = myList.selectedIndex
if row != -1: # make sure there is something selected = system.dataset.deleteRow(, row)
