TreeListColumn | A TreeListColumn object or descendant that represents a column with the specified name, field name or caption. null (Nothing in Visual Basic) if the column was not found. |
Remarks
The Item property allows you to obtain a column by specifying its name, field name or caption. If the column’s Name property matches the key parameter, it is returned by the Item property.
If the column isn’t found, a search is performed for a column whose TreeListDataColumn.FieldName property matches the search parameter. Since multiple columns can be bound to the same data source field, the first found column is returned.
Finally, if the column isn’t found, the Item property returns the first found column whose Caption property matches the search parameter. Otherwise, the Item property returns null.
