ActiveColumn Property

Visual Studio .NET 2003

Returns as an integer the column number that contains the active cell in a Grid control. Not available at design time; read-only at run time.

Grid.ActiveColumn

Remarks

ActiveColumn returns zero if the grid doesn't have the focus.

Example

The following example shows the use of the ActiveColumn Grid property.

m.cTalk=SET("TALK")

PUBLIC oTlb
oTlb = NEWOBJECT("tlbDemo")
oTlb.SHOW

PUBLIC oFrmDemo
oFrmDemo=NEWOBJECT("frmDemo")
oFrmDemo.SHOW

READ EVENTS

RELEASE oTlb
RELEASE oFrmDemo
SET TALK &cTalk

RETURN
