'Usage Dim instance As PrimaryAxis
public enum PrimaryAxis : System.Enum
| Member | Description |
|---|---|
| Both | Both the vertical and horizontal axes must be completely visible (see item 1 in the image below). |
| Horizontal | The horizontal axis ust be completely visible (see item 2 in the image below). |
| None | Neither the vertical nor horizontal axes must be completely visible (see item 4 in the image below). |
| Vertical | The vertical axis must be completely visible (see item 3 in the image below). |
The primary axis determines which DataRow will receive the focus when the page-up or page-down buttons are pressed.
For example, let's assume that the focus is currently in the top-left DataRow (item 0). If the page-down button is pressed while the ItemsPrimaryAxis Property is set to Vertical, the DataRow on the bottom-right whose vertical axis is completely visible will receive the focus (item 3). If set to Horizontal, the DataRow on the bottom-right whose horizontal axis is completely visible will receive the focus (item 2), while setting the property to Both will send the focus to the DataRow whose vertical and horizontal axes are completely visible (item 1). Setting the ItemsPrimaryAxis property to None indicates that neither the vertical nor horizontal axes need to be completely visible and thus the focus will be sent to the last DataRow on the bottom-right that is at least partially visible (item 4).
The ItemsPrimaryAxis property applies only when a pixel-scrolling panel template is assigned to a grid's ItemsPanel property. The default VirtualizingStackPanel and VirtualizingCardPanel panels use item-scrolling rather than pixel-scrolling.
