Class TActiveDropDownListColumn

TActiveDropDownListColumn class

TActiveDropDownListColumn represents a column that is bound to a field in a data source.

This is the active counterpart to the TDropDownListColumn control. For that purpose, if sorting is allowed, the header links/buttons are replaced by active controls.

Please refer to the original documentation of the TDropDownListColumn for usage.

Methods summary
protected
# initializeHeaderCell( TTableCell $cell, integer $columnIndex )

Initializes the header cell.

Initializes the header cell.

This method attempts to use getHeaderRenderer HeaderRenderer to instantiate the header cell. If that is not available, it will populate the cell with an image or a text string, depending on getHeaderImageUrl HeaderImageUrl and getHeaderText HeaderText property values.

If the column allows sorting, image or text will be created as a button which issues Sort command upon user click.

Parameters

$cell
TTableCell
the cell to be initialized
$columnIndex
integer
the index to the Columns property that the cell resides in.
