| DragDelayTimerDispatcherPriority | Returns the dispatcher priority for the drag delay timer |
| DragDelayTimerInterval | Returns the interval for the drag delay timer in milliseconds. |
| DragThreshold | Returns a value which represents the amount that the mouse must move from the inital MouseDown position before dragging will start. (Inherited from Infragistics.Windows.Selection.SelectionStrategyBase) |
 | IgnoreNextMouseMove | Returns/sets whether the next mouse move should be ignored. (Inherited from Infragistics.Windows.Selection.SelectionStrategyBase) |
| InDragMode | Returns/sets whether the strategy is currently in drag mode. (Inherited from Infragistics.Windows.Selection.SelectionStrategyBase) |
| InitialXPos | Returns/sets the X coordinate of the mouse when the initial MouseDown was received. (Inherited from Infragistics.Windows.Selection.SelectionStrategyBase) |
| InitialYPos | Returns/sets the Y coordinate of the mouse when the initial MouseDown was received. (Inherited from Infragistics.Windows.Selection.SelectionStrategyBase) |

| IsLeftMouseButtonDown | Returns true if the left mouse button is currently pressed (Inherited from Infragistics.Windows.Selection.SelectionStrategyBase) |
| IsShiftKeyPressed | Returns true if the shift key is currently pressed. (Inherited from Infragistics.Windows.Selection.SelectionStrategyBase) |
| PixelThresholdForHorizontalAutoScroll | Returns the number of pixels inside the left or right edge of the ScrollArea within which auto scrolling will take place (Inherited from Infragistics.Windows.Selection.SelectionStrategyBase) |
| PixelThresholdForVerticalAutoScroll | Returns the number of pixels inside the top or bottom edge of the ScrollArea within which auto scrolling will take place (Inherited from Infragistics.Windows.Selection.SelectionStrategyBase) |
| SelectionHost | Returns the SelectionHost (usually the control) for the strategy. (Inherited from Infragistics.Windows.Selection.SelectionStrategyBase) |
| ShouldSelect | Returns true if the strategy should select, or false if it should unselect. |
| Name | Description | |
|---|---|---|
 | CancelPendingOperations | Called to cancel any pending mouse drag operation (Inherited from Infragistics.Windows.Selection.SelectionStrategyBase) |
| CanItemBeNavigatedTo | Overridden. Returns true if item can be selected. |
| OnMouseLeftButtonDown | Overridden. Called when a left mouse down is received. |
| OnMouseLeftButtonUp | Overridden. Called when a left mouse up is received while the mouse is captured. |
| OnMouseMove | Overridden. Called when mouse move message is received. |
| SelectItemViaKeyboard | Overridden. Called to select an item as a result of a key press |
| Name | Description | |
|---|---|---|
 | DragMove | Used to verify the drag timers and call the ISelectionHost.OnDragMove (Inherited from Infragistics.Windows.Selection.SelectionStrategyBase) |
| DragStart | Called when dragging is to be started. It calls OnDragStart off the SelectionManager. (Inherited from Infragistics.Windows.Selection.SelectionStrategyBase) |
| GetMousePointInRootElementCoordinates | Returns a point in RootElement coordinates that corresponds to the mouse position contained in mouseEventArgs. (Inherited from Infragistics.Windows.Selection.SelectionStrategyBase) |
 | IsWithinDblClickThreshold | Determines if the mouse is still within the dblclick time and movement thresholds since the last mouse down. (Inherited from Infragistics.Windows.Selection.SelectionStrategyBase) |
| ManageTimers | Determines during a drag operation whether timers are required to generate horizontal or vertical scrolling. (Inherited from Infragistics.Windows.Selection.SelectionStrategyBase) |
| OnDragStartCanceled | Overridden. This method is called when the selection manager cancels OnDragStart. The default implementation releases the capture. |
| ProcessMouseLeftButtonDown | OnMouseDown handler that takes a third parameter that specifies whether we are forcing a drag or not. SelectionStrategySingleAutoDrag passes true to this. |
| ShouldStartDrag | Returns true if dragging should start (when we're in preDrag mode). The default implementation checks to see if the x or y coords exceed the drag threshold. (Inherited from Infragistics.Windows.Selection.SelectionStrategyBase) |
| StartDragDelayTimer | Starts the timer used to ensure a delay period before dragging starts. |
| StopDragDelayTimer | Stops the timer used to ensure a delay period before dragging starts. |
| StopHorizontalAutoScrollTimer | Stops the timer used for horizontal auto scrolling. (Inherited from Infragistics.Windows.Selection.SelectionStrategyBase) |
| StopVerticalAutoScrollTimer | Stops the timer used for vertical auto scrolling. (Inherited from Infragistics.Windows.Selection.SelectionStrategyBase) |
