Syntax

Finding out the stored item or variable of a control Hide the details

<Stored item/variable> = <Control used>.StoredItem

<Stored item/variable>: Character string

Name of stored item for the specified control. This item belongs to the data file the control is based on (returned or modified by the BrowsedFile property).
Name of stored variable for the specified control. This name has the following format ":<prefix><Variable Name>" or ":<Variable Name>" (the prefix is used only if the code style is enabled in the project).
This variable belongs to the variable the control is based on (returned or modified with the BrowsedFile property).
Empty string ("") if no stored item/variable is associated with the control.

<Control used>: Control name

Name of the control to be used:
Table control,
List Box control,
Combo Box control.

Modifying the stored item/variable of a control Hide the details

<Control used>.StoredItem = <New item/variable>

<Control used>: Control name

Name of the control to be used:
Table control,
List Box control,
Combo Box control.

<New item/variable>: Character string

Name of new stored item for the specified control. This item must belong to the data file the control is based on (returned or modified by the BrowsedFile property).
Name of the new stored variable for the specified control. This name has the following format ":<prefix><Variable name>" or ":<Variable name>". The prefix must be specified only if the code style is enabled in the project (whether prefixes are displayed or not).
This variable belongs to the variable the control is based on (returned or modified with the BrowsedFile property).
Empty string ("") if no stored item/variable must be associated with the control.

Remarks

Value property

The StoredItem property modifies the value returned by the Value property.

Two distinct cases may occur:

The List Box or Table control is handled programmatically OR the StoredItem property corresponds to an empty string (""). The Value property allows you to:
- Find out the selected row. If no row is selected, the Value property returns -1. If the List Box control (or the Table control) is multi-selection, the number of the last selected row is returned.
- Move the selection by specifying the number of the new row to select. The rows that were selected beforehand are deselected.
  To identify the selected row, use one of the following syntaxes:
  
  ResRow = <List Box or Table control>.Value
  ResRow = <List Box or Table control>
The List Box or Table control is based on a data file AND the StoredItem property is not an empty string (""). The Value property is used to identify the stored item for the record associated with the selected row. If no row is selected, the Value property returns an empty string ("").
To find out the stored item associated with the selected row, the following syntaxes are equivalent:

ResStoredItem = <List Box or Table control>.Value
ResStoredItem = <List Box or Table control>.StoredItem

DataBinding property

The StoredItem property is often used in combination with the DataBinding property . This association creates an automatic link between two data files when FileToScreen and ScreenToFile are called.

Table control populated programmatically

If a Table control populated programmatically must display data coming from a data file, a query or a view:

Create a Table control populated programmatically in the window editor or in the page editor.
In the code, specify the item to loop through with the BrowsedItem property. This item must belong to the data file, to the query or to the view whose data will be displayed in the Table control populated programmatically.
In the code, specify the item to be stored with the StoredItem property. This item must belong to the data file, to the query or to the view whose data will be displayed in the Table control populated programmatically.
Use FileToMemoryTable to initialize the Table control with the desired data. The data will be sorted according to the specified search item.
The DisplayedItem property will be automatically initialized.

List Box control populated programmatically

If a List Box or Combo Box control populated programmatically must display data coming from a data file, a query or a view:

Create a List Box or Combo Box control populated programmatically in the window editor or in the page editor.
Use FileToMemoryList to initialize the control with the desired data.
The BrowsedFile, DisplayedItem, BrowsedItem and StoredItem properties will be automatically initialized.

Seeking and selecting an element in a List Box or Combo Box control based on a data file

To seek and/or select an element in a List Box or Combo Box control based on a data file, we recommend that you use the following syntax:

LIST_OrderList.StoredItem = "CustomerID"
// Find and select the element whose CustomerID is "135"
LIST_OrderList = 135
// If the element sought is not found, LIST_OrderList will be set to -1

Limitations

The StoredItem property applies only to the following controls:

Table control,
List Box control,
Combo Box control,
ListView control,
Looper control.
