ParametersOutReadyEventArgs.ParameterValues Property
NOTE: This API is now obsolete.
Gets or sets the parameter values provided by a Web Part that implements the IParametersOutProvider interface when the ParametersOutReady event occurs
Namespace: Microsoft.SharePoint.WebPartPages.Communication
Assembly: Microsoft.SharePoint (in Microsoft.SharePoint.dll)
Syntax
<ObsoleteAttribute("Use System.Web.UI.WebControls.WebParts.IWebPartParameters instead")> _
Public Property ParameterValues As String()
Get
Set
Dim instance As ParametersOutReadyEventArgs
Dim value As String()
value = instance.ParameterValues
instance.ParameterValues = value
[ObsoleteAttribute("Use System.Web.UI.WebControls.WebParts.IWebPartParameters instead")]
public string[] ParameterValues { get; set; }
Property Value
Type: []
An array of parameter values.
Remarks
The ParameterValues property is a one-dimensional array of strings where each string is the value of a parameter. The number and order of parameters contained in this array must match those specified in the ParametersOutProviderInitEventArgs argument of the ParametersOutProviderInit event.
Examples
The following code example shows an overridden PartCommuncationMain method that uses the ParameterValues property to set the parameter values of an instance of the ParametersOutReadyEventArgs class. This code example is part of a larger example provided for the IParametersOutProvider interface.
' Step #8: Override the PartCommunicationMain() method.
' The PartCommunicationMain method is called by the Web Part infrastructure on the client during the ASP.NET PreRender
' event to allow the part to pass its primary data to the other connected parts.
' It is important to always fire either the ParametersOutReady or the NoParametersOut event. Some parts
' may not behave properly if they are left waiting for this information.
' ParametersOutReady should be fired to send the parameters.
' NoParametersOut should be fired to indicate that there is no change in the parameters.
