    CacheSelectionRendering Property
    In This Topic
    Whether or not to cache the internal image map created by the control.
    Syntax
    'Declaration
 
<CategoryAttribute("General")>
<DescriptionAttribute("Whether or not to cache the internal image map created by the control.")>
<DefaultValueAttribute(True)>
Public Property CacheSelectionRendering As Boolean
    'Usage
 
Dim instance As Settings
Dim value As Boolean
 
instance.CacheSelectionRendering = value
 
value = instance.CacheSelectionRendering
    [Category("General")]
[Description("Whether or not to cache the internal image map created by the control.")]
[DefaultValue(true)]
public bool CacheSelectionRendering {get; set;}
    Remarks
    When you use an interactivity operations like tooltips, events and cursors the control internally performs a render to determine the chart object under the mouse cursor. This render is cached for reuse by default, which greatly improves the speed of subsequent interactivity requests. The generated image map is automatically updated when you refresh the chart or drag it with the trackball. You may wish to turn off this cache to reduce the memory footprint of the control.
    Example
    The following code disables the selection cache: 
    ChartControl.Settings.CacheSelectionRendering = False
    ChartControl.Settings.CacheSelectionRendering = false;
