IsApplicable Method (NChartAjaxTechnology)

In This Topic

Tests if the client web browser supports callbacks and XML HTTP requests.

Syntax

Visual Basic
C#

'Declaration
 
Public Overrides Function IsApplicable( _
   ByVal designMode As System.Boolean _
) As System.Boolean

'Usage
 
Dim instance As NChartAjaxTechnology
Dim designMode As System.Boolean
Dim value As System.Boolean
 
value = instance.IsApplicable(designMode)

public override System.bool IsApplicable( 
   System.bool designMode
)

Parameters

designMode: Indicates if the NChartAjaxTechnology is being tested in design mode.

Return Value

True if in design mode or if the client browser supports callbacks; else returns false.

Remarks

If this method returns false to the Nevron AJAX framework, the default post-back mode will be used. So it is recommended to provide post-back event handling when using the Nevron Chart web control in AJAX mode. This way web browsers that do not support AJAX will still provide at least part of the desired charting functionality.

Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
