A node‘s data cells display values of the data store record that the node represents. In editable data cells (see the tree list’s OptionsData.Editing property), values can be modified through associated in-place editors.
The position and size of the data, footer, and group footer cells are determined by the column header layout. End-users can adjust a cell’s width, and make it span across multiple lines.
In group nodes, a categorized column cell occupies the entire node (spans all the columns). The number of visible data cells varies in ordinary nodes, and is dependent upon the visibility of the containing columns.
The table below lists the main properties that relate to data cells.
