GetExtent() Method

Returns the absolute width of the band.
Syntax
'Declaration
 
Public Overloads Function GetExtent() As Integer
public int GetExtent()
Remarks

You can use the GetExtent method to return the total width of a band, using the scale mode of the grid's container. This method does not take into account how much of the band is visible, the size of the ColScrollRegion, or even how much screen area is available on the system. It simply calculates the total width that would be required to display the band in its entirety.

Example
Following code prints out the origin and extent of each band in the UltraGrid. Origin is where the band starts and extent includes the area spanning all the columns of the band. Both GetOrigin and GetExtent methods take BandOrigin enumeration parameter. It indicates what gets taken into account when calculating origin or the extent. For example, when the RowCellArea is specified, returned value doesn't include the row selectors and the space before it. There are overloads that do not take any parameter. These overloads pass PreRowArea to their respective overloads taking the parameter.
