Width Property (ColScrollRegion)

Returns or sets the width of an object in container units.
Syntax
'Declaration
 
Public Property Width As Integer
public int Width {get; set;}
Remarks

The Width property is used to determine the horizontal dimension of an object. It is generally expressed in the scale mode of the object's container, but can also be specified in pixels.

For the ColScrollRegion object, this property always includes the vertical scrollbar's Width for the RowScrollRegion.

Example
Following code illustrates how you can use combination of BeforeColRegionSplit and BeforeColRegionSize events to prevent the user from resizing any of the column scroll regions too small.

For an overview of how to handle events in Visual Basic or Visual C#, see Event Handlers in Visual Basic and Visual C#. For specific information and code examples illustrating how to consume events in your application, see Consuming Events in the .NET Framework Developer's Guide.
