Obtains the number of the current column. The current column is the column that has focus.
integer dwcontrol.GetColumn ( )
Argument |
Description |
|---|---|
dwcontrol |
A reference to a DataWindow control DataStore, or child DataWindow |
Returns the number of the current column in dwcontrol. Returns 0 if no column is current (because all the columns have a tab value of 0, making all of them uneditable), and -1 if an error occurs. If dwcontrol is NULL, the method returns NULL.
GetColumn and GetClickedColumn, when called in the Clicked or DoubleClicked event, can return different values. The column the user clicked doesn’t become current until after the event.
Use GetColumnName (instead of GetColumn) when you need the column’s name. Use SetColumn to change the current column.
Using with other controls
For use with ListView controls, see GetColumn in the PowerScript
Reference.
The current column
A column becomes the current column after the user tabs to
it or clicks it or if a script calls the SetColumn method. A column
cannot be current if it cannot be edited (if it has a tab value
of 0).
A DataWindow always has a current column, even when the control is not active, as long as there is at least one editable column.
These statements return the number of the current column in dw_Employee:
integer li_ColNum
li_ColNum = dw_employee.GetColumn()
