Namespace: XSharp.VO.SDK
Assembly: XSharp.VOGUIClasses (in XSharp.VOGUIClasses.dll) Version: 2.21
SyntaxVIRTUAL METHOD ColumnFocusChange( oDataColumn AS DataColumn, lHasFocus AS LOGIC ) AS Object
Parameters
- oDataColumn
- Type: DataColumn
The column that is gaining or losing focus. - lHasFocus
- Type: Logic
TRUE indicates the column is gaining focus; FALSE indicates the column is losing focus.
Return Value
Type: ObjectRemarks
When column focus is changed (i.e., the user moves from one column to another), typically there will be two events generated, thus ColumnFocusChange() will be called twice. The first event will be for the previous column losing focus and the second event will be for the new column gaining focus. You can trap either event by checking the value of lHasFocus.
Examples
The following code demonstrates how the ColumnFocusChange handler can be used:
X#
1CLASS MyDataBrowser INHERIT DATABROWSER 2METHOD ColumnFocusChange(oDataColumn, lHasFocus) CLASS MyDataBrowser 3SUPER:FocusChange(oDataColumn, lHasFocus) 4IF lHasFocus 5TextBox{ SELF, oDataColumn:Name, "Gaining Focus"}:Show() 6ELSE 7TextBox{ SELF, oDataColumn:Name, "Losing Focus"}:Show() 8ENDIF 9RETURN SELF
