SelectedRow - cCJGridDataSource

Returns the row number of the SelectedRow

Type: Function
Return Data Type: Integer

Syntax

Function SelectedRow Returns Integer

Call Example

Get SelectedRow to IntegerVariable

Description

SelectedRow determines which row in the datasource is currently selected. This is the row that is the current focus row of the grid. It is crucial that the SelectedRow in the datasource object match the grid's focus row. The SelectedRow is also used to synchronize activity between a DataDictionary object and the datasource.

The cCJGrid class carefully maintains SelectedRow, which ensures that the grid, the datasource, and external data (e.g., DataDictionary objects and file buffers) are all synchronized. If you need to know which row is the focus row, you must query SelectedRow. It is possible for no row to be selected, in which case, SelectedRow is -1.

// Find the RowId of the SelectedRow
RowId riId
Integer iSel
Handle hoDataSource

Get phoDataSource to hoDataSource
Get SelectedRow of hoDataSource to iSel
If (iSel<>-1) Begin
    Get RowTag of hoDataSource iSel to riId 
End

A selected column is also maintained. The datasource object does not care which column is selected and therefore SelectedColumn is maintained by the cCJGrid class.
