FilterColumn: Number;
The FilterColumn property determines column index for filter check.
Use JSON or the setFilter(string, column) method to set the property value and the getFilterColumn() method to get the property value.
Executing the example requires the SimpleTreeList component with the Tree identifier (see Example of Creating the SimpleTreeList Component).
// Set filter Tree.setFilter("Node2", 0); // Get filter check column Tree.getFilterColumn(); // -> 0
After executing the example the current column for filter check is obtained.
