StandardTouchTool.QuickUpdateEnabled Property
Gets or sets a flag indicating if certain layers should be turned off during pan, zoom and rotate interactions.
Syntax
public System.Boolean QuickUpdateEnabled { get; set; }Property Value
Default: true
True if certain layers should be turned off during pan zoom and rotate interactions; False otherwise.
Remarks
If this property is True, the tool will set an update attribute (see View.UpdateAttributes) with the key quickUpdate, for all updates during pan and zoom interactions. This will temporarily turn off all layers with the property Layer.EnabledDuringQuickUpdates set to False, to increase performance and provide better feedback to the user. When the pan or zoom is complete, a full update without this flag will be performed, to restore all layers to their correct state.
Note that Layer.EnabledDuringQuickUpdates can only be used to turn off a layer during quick updates. If you want to do the opposite, i.e. enable a layer only during quick updates, you can achieve this by setting an appropriate Layer.Condition instead, that checks if the quickUpdate attribute is set; the condition can formulated simply as
quickUpdate
since the attribute will be either True or undefined (null). This can be used to temporarily turn on a fast replacement layer when other, slower layers are disabled during the quick update.
