TcxExtLookupComboBoxProperties

Remarks

Use attributes of the Properties object to adjust settings of ExtLookupEditor. The main attributes are:

• the View property

Represents the View displayed within the dropdown window of ExtLookupEditor

• the KeyFieldNames property

Specifies one or more fields matching the edit value(s). See the EditValue property to get the edit value(s). If the KeyFieldNames property specifies several field names delimited by the semicolon, the EditValue property holds an array of variants (values from the currently selected record in the dropdown View).

For data-aware ExtLookupEditors (TcxDBExtLookupComboBox), the KeyFieldNames property must correspond to the field being edited by ExtLookupComboBox. This field is set via the DataBinding.DataField property

• the ListFieldItem property

This property is used to specify the column in the dropdown View whose value is displayed in the edit box. It is obtained from the current record.
