CacheSelectionRendering Property

In This Topic

Whether or not to cache the internal image map created by the panel.

Syntax

Visual Basic
C#

'Declaration
 
<System.ComponentModel.CategoryAttribute("General")>
<System.ComponentModel.DescriptionAttribute("Whether or not to cache the internal image map created by the control.")>
<System.ComponentModel.DefaultValueAttribute(True)>
<System.Xml.Serialization.XmlAttributeAttribute()>
Public Property CacheSelectionRendering As System.Boolean

'Usage
 
Dim instance As NImageMapDockPanel
Dim value As System.Boolean
 
instance.CacheSelectionRendering = value
 
value = instance.CacheSelectionRendering

[System.ComponentModel.Category("General")]
[System.ComponentModel.Description("Whether or not to cache the internal image map created by the control.")]
[System.ComponentModel.DefaultValue(true)]
[System.Xml.Serialization.XmlAttribute()]
public System.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:

Visual Basic

somePanel.CacheSelectionRendering = False

somePanel.CacheSelectionRendering = false;
