Column Header
- 2 minutes to read
Column headers identify columns in the tree list. All column headers are located in the column header panel.
A column header contains:
A caption string that identifies the column’s content.
A caption glyph that provides graphical information about the column’s content.
A sort glyph that identifies the sort order applied to the column’s values.
Columns can be moved within the tree list by dragging their headers, and can be resized by dragging header edges. Moving and sizing a column’s header or changing its visibility affects all data and summary cells that correspond to this column and automatically adjusts the column header panel’s height. You can prohibit columns from being resized or moved within the tree list, as well as prohibit bands from accepting columns of other bands.
The table below lists the main properties that relate to column headers.
