BrowsedItem (Property)

Find out the item used to automatically browse the controls linked to a data file.
Modify the item used to automatically browse the controls linked to a data file. Then, the browse is reinitialized.

For a report on file, ..BrowsedItem allows you to modify the item used to browse the file. In this case, this property can only be used in the opening process of the report.

Remark: This item is defined when creating the control or the report. This item can be modified in the "Data" tab of the element description.

Example

// -- Opening code of report
// Change the browsed file
RPT_Report1..SourceName = Customer
// New search item for "Customer" file
RPT_Report1..BrowsedItem = CustomerID

Remarks

Type of browse

Automatic browse: The browse of data file and the display of data in the control are automatically performed. No specific programming is required.
The sort is performed on the search item defined in the "Content" tab of the object description. If a filter is specified ("Filter on the search item" in the "Content" tab of the object description), this filter is used. No browse process is run for the specified object.
Programmed browse: The developer must program the browse of the data file and the display of data in the Table control.
The "Read the first record", "Read the previous record", "Read the next record" and "Read the last record" processes are run. A programmed browse gives total control on the order and on the filter used for the records. However, a programmed browse is a lot more complex and slower than an automatic browse.

Handling the controls linked to a data file via properties

The records displayed in a control linked to a file come from the data file or from the query specified by ..BrowsedFile.
The sort direction is defined by ..BrowsedItem.
The records can be filtered by ..Filter or by HFilter.

Modifying the properties linked to the browse of a control

To modify ..BrowsedItem, ..Filter and ..BrowsedFile, we advise you to:

Stop the browse by assigning an empty string ("") to ..BrowsedFile.
Modify the relevant properties.
Restart the browse with ..BrowsedFile.

This method is used to optimize the modifications performed. Indeed, each one of the modifications performed individually restarts the browse. These operations can become quite slow when they are performed on large data files.

Memory table

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

Create a memory Table control in the editor.
In your program, specify the item to browse with ..BrowsedItem. This item must belong to the data file, to the query or to the view whose data will be displayed in the memory Table control.
Use FileToMemoryTable to initialize the Table control with the requested data. The data will be sorted according to the specified search item.
..DisplayedItem will be automatically initialized.

Memory List Box and Combo Box control

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

Create a memory List Box or Combo Box control in the editor.
Use FileToMemoryList to initialize the List Box or Combo Box control with the requested data.
..BrowsedFile, ..DisplayedItem, ..BrowsedItem and ..StoredItem will be automatically initialized.

Limits

..BrowsedItem only applies to:

the reports whose data source is a data file.
the controls (List Box, Table and Combo Box) of a window.
