EDIT INPLACE { aControlDef1 , aControlDef2 , ... , aControlDefN }

Control Definition Array:

TEXTBOX { cControlType , cDataType , cInputMask , cFormat }

cControlType = 'TEXTBOX' (Required)
cDataType = 'CHARACTER' , 'NUMERIC' , 'DATE' (Required)
cInputMask = cInputMask (Optional)
cFormat = cFormat (Optional)

DATEPICKER { cControlType , cControlStyle }

cControlType = 'DATEPICKER' (Required)
cControlStyle = 'DROPDOWN' , 'UPDOWN' (Required)

COMBOBOX { cControlType , acItems }

cControlType 'COMBOBOX' (Required)
acItems (Required)

SPINNER { cControlType , nRangeMin , nRangeMax }

cControlType 'SPINNER' (Required)
nRangeMin (Required)
nRangeMax (Required)

CHECKBOX { cControlType , cCheckedLabel , cUnCheckedLabel }

cControlType 'CHECKBOX' (Required)
cCheckedLabel (Required)
cUnCheckedLabel (Required)

DYNAMIC { cControlType , bCodeBlock }

cControlType = 'DYNAMIC' (Required)
bCodeBlock = CodeBlock that return array with normal type control (Required)
                  to CodeBlock is passed two params - row and column indexes.

Data type for each column will depend control specified.

NUMERIC TEXTBOX : NUMERIC
DATE TEXTBOX : DATE
CHARACTER TEXTBOX : CHARACTER
SPINNER : NUMERIC
COMBOBOX : NUMERIC
CHECKBOX : LOGICAL

Remarks

If MULTISELECT clause is used VALUE must be a numeric array, containing the index position of selected items.

If EDIT clause is used, by doubleclicking an item, will open an editing window allowing to change the item content.

EDIT and MULTISELECT clauses can't be used simultaneously.

The leftmost column in a grid control must be left aligned.

When used in control definition, Header property must be loaded with a character array containing as elements as control columns.

When AddColumn / DeleteColumn methods are used, all items in grid (if any) will be lost.
