Public Property SelectionStart As Double

Visual Basic (Usage)	Copy Code
Dim instance As Cursor Dim value As Double   instance.SelectionStart = value   value = instance.SelectionStart

public double SelectionStart {get; set;}

Return Value

A Double value that represents the start position of a cursor's range selection.

A user can select a range by clicking on the left mouse button and then moving the cursor position by dragging the mouse.  In addition a range selection can be set programmatically using either the SelectionEnd and SelectionStart properties or the SetSelectionPosition or SetSelectionPixelPosition  methods.

The start position of a range selection is calculated as a value of the axis that the cursor belongs to.  For example, if the cursor belongs to the primary X axis then setting this to a value of January 1, 2000 will result in the end of the selected region occurring at January 1, 2000 along the primary X axis.

To programmatically remove a range selection set the beginning and end points of the range to Double.NaN using the SelectionEnd and SelectionStart properties, or alternatively use the SetSelectionPosition method.
