ParametersOutProviderInitEventArgs.ParameterOutProperties Property

  • 아티클

NOTE: This API is now obsolete.

Gets or sets the property values of an array of parameters provided by a Web Part that implements the IParametersOutProvider interface when the ParametersOutProviderInit event occurs.

Namespace:  Microsoft.SharePoint.WebPartPages.Communication
Assembly:  Microsoft.SharePoint (in Microsoft.SharePoint.dll)

Syntax

'Declaration
<ObsoleteAttribute("Use System.Web.UI.WebControls.WebParts.IWebPartParameters instead")> _
Public Property ParameterOutProperties As ParameterOutProperty()
    Get
    Set
'Usage
Dim instance As ParametersOutProviderInitEventArgs
Dim value As ParameterOutProperty()

value = instance.ParameterOutProperties

instance.ParameterOutProperties = value

[ObsoleteAttribute("Use System.Web.UI.WebControls.WebParts.IWebPartParameters instead")]
public ParameterOutProperty[] ParameterOutProperties { get; set; }

Property Value

Type: []
An array of type ParameterOutProperty that specifies parameter values.

Remarks

The ParameterOutProperties property provides an array of ParameterOutProperty objects, each of which corresponds to a parameter. The number and order of parameters represented in this array must match those specified in the ParametersInReadyEventArgs argument of the ParametersOutReady event.

Examples

The following code example shows an overridden PartCommunicationInit method that uses the ParametersOutProperties property to set the array of values for an instance of the ParametersOutProviderInitEventArgs class. This code example is part of a larger example provided for the IParametersOutProvider interface.

// Step #7: Override the PartCommunicationInit method.
// The PartCommunicationInit method is called by the Web Part infrastructure during the ASP.NET PreRender 
// event to allow the part to pass initialization information to the other connected parts.
// It is important to always pass initialization information. Some parts
// may not behave properly if this initialization information is not received.

public override void PartCommunicationInit()
{
    // Ensure that all of the Web Part's controls are created.
    EnsureChildControls();

    // Check if connected.
    if(_connected)
    {
        // If there is a listener, send init event.
        if (ParametersOutProviderInit != null)
        {
            // Need to create the ParametersOutProviderInitEventArgs object for the ParametersOutProviderInit event.
            ParametersOutProviderInitEventArgs parametersOutProviderInitInitEventArgs = new ParametersOutProviderInitEventArgs();
            
            // Set the ParameterOutProperties.
            parametersOutProviderInitInitEventArgs.ParameterOutProperties = new ParameterOutProperty[4];

            // There are 4 parameters types that will be passed: Font Family, Color, Weight, and Size.
            parametersOutProviderInitInitEventArgs.ParameterOutProperties[0] = new ParameterOutProperty();
            parametersOutProviderInitInitEventArgs.ParameterOutProperties[0].Description = _fontFamilyParamDescription;
            parametersOutProviderInitInitEventArgs.ParameterOutProperties[0].ParameterDisplayName = _fontFamilyParamDisplayName;

            parametersOutProviderInitInitEventArgs.ParameterOutProperties[1].ParameterName = _fontColorParamName;

            parametersOutProviderInitInitEventArgs.ParameterOutProperties[3].ParameterDisplayName = _fontSizeParamDisplayName;
            parametersOutProviderInitInitEventArgs.ParameterOutProperties[3].ParameterName = _fontSizeParamName;

            // Fire the ParametersOutProviderInit event.
            ParametersOutProviderInit(this, parametersOutProviderInitInitEventArgs);
        }
    }
