Public Methods

Method Description
GridSplitter ( ) : System

Initializes a new instance of the T:Microsoft.Silverlight.Testing.Controls.GridSplitter class.
OnApplyTemplate ( ) : void

Builds the visual tree for the T:Microsoft.Silverlight.Testing.Controls.GridSplitter control when a new template is applied.

Protected Methods

Method Description
OnCreateAutomationPeer ( ) : System.Windows.Automation.Peers.AutomationPeer

Returns a T:System.Windows.Automation.Peers.GridSplitterAutomationPeer for use by the Silverlight automation infrastructure.

Private Methods

Method Description
CancelResize ( ) : void

Cancel the resize operation in progress.
ChangeVisualState ( ) : void

Method to change the visual state of the control.
ChangeVisualState ( bool useTransitions ) : void

Change to the correct visual state for the GridSplitter.
CreatePreviewLayer ( Grid parentGrid ) : void

Creates the preview layer and adds it to the parent grid.
DragValidator_DragCompletedEvent ( object sender, System.Windows.Controls.Primitives.DragCompletedEventArgs e ) : void

Handle the drag completed event to commit or cancel the resize operation in progress.
DragValidator_DragDeltaEvent ( object sender, System.Windows.Controls.Primitives.DragDeltaEventArgs e ) : void

Handle the drag delta event to update the UI for the resize operation in progress.
DragValidator_DragStartedEvent ( object sender, System.Windows.Controls.Primitives.DragStartedEventArgs e ) : void

Handle the drag started event to start a resize operation if the control is enabled.
GetActualLength ( DefinitionAbstraction definition ) : double

Get the actual length of the given definition.
GetDeltaConstraints ( ) : double[]

Determine the max and min that the two definitions can be resized.
GetEffectiveResizeBehavior ( GridResizeDirection direction ) : GridResizeBehavior

Determine the resize behavior based on the given direction and alignment.
GetEffectiveResizeDirection ( ) : GridResizeDirection

Determine the resize direction based on the horizontal and vertical alignments.
GetGridDefinition ( Grid grid, int index, GridResizeDirection direction ) : DefinitionAbstraction

Create a DefinitionAbstraction instance for the given row or column index in the grid.
GridSplitter_KeyDown ( object sender, System.Windows.Input.KeyEventArgs e ) : void

Handle the key down event to allow keyboard resizing or canceling a resize operation.
InitializeAndMoveSplitter ( double horizontalChange, double verticalChange ) : bool

Initialize the resize data and move the splitter by the specified amount.
InitializeData ( bool showsPreview ) : void

Initialize the resizeData object to hold the information for the resize operation in progress.
IsStar ( DefinitionAbstraction definition ) : bool

Determine if the given definition has its size set to the "*" value.
KeyboardMoveSplitter ( double horizontalChange, double verticalChange ) : bool

Called by keyboard event handler to move the splitter if allowed.
MoveSplitter ( double horizontalChange, double verticalChange ) : void

Move the splitter and resize the affected columns or rows.

Only one of horizontalChange or verticalChange will be non-zero.

OnIsEnabledChanged ( object sender, System.Windows.DependencyPropertyChangedEventArgs e ) : void

Called when the IsEnabled property changes.
RemovePreviewControl ( ) : void

Remove the preview control from the preview layer if it exists.
SetDefinitionLength ( DefinitionAbstraction definition, GridLength length ) : void

Set the height/width of the given row/column.
SetLengths ( double definition1Pixels, double definition2Pixels ) : void

Set the lengths of the two definitions depending on the split behavior.
SetupDefinitionsToResize ( ) : bool

Determine which adjacent column or row definitions need to be included in the resize operation and set up resizeData accordingly.
SetupPreview ( ) : void

Add the preview layer to the Grid if it is not there already and then show the preview control.
UpdateTemplateOrientation ( ) : void

This code will run whenever the effective resize direction changes, to update the template being used to display this control.
