InitEventArgs class

NOTE: This API is now obsolete.

Represents the object type returned by the WebPart.GetInitEventArgs method.

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

[ObsoleteAttribute("Use ConnectionProvider or ConnectionConsumer attribute to create ConnectionPoint instead.")]
public class InitEventArgs : EventArgs

The following code example shows an overridden GetInitEventArgs method that returns an instance of the InitEventArgs class. This code example is part of a larger example provided for the IFilterConsumer interface.

// Step #8: Override the GetInitEventArgs method.
// GetInitEventArgs() is called by the Web Part infrastructure during 
// the ASP.NET PreRender event to gather the 
// necessary information it needs to build the transformer dialog. The 
// transformer dialog is needed when connecting different interfaces 
// such as IRowProvider to ICellConsumer. The transformer dialog allows 
// the user to map the fields between the interfaces. The 
// GetInitEventArgs()method only needs to be implemented for interfaces 
// that can participate in a transformer which are the following:
// ICellConsumer, IRowProvider, IFilterConsumer, 
// IParametersOutProvider, IParametersInConsumer.
// <param name="interfacename">Name of interface on which the Web Part 
// infrastructure is requesting information</param>
// <returns>An InitEventArgs object</returns>
public override InitEventArgs GetInitEventArgs(string interfaceName)
    // Check if this is my particular cell interface.
    if (interfaceName == "MyFilterConsumerInterface")
        //Ensure that all of the Web Part's controls are created.
        //The _filterFieldNames and _filterFieldDisplayNames are set 
        //during EnsureChildControls()

        // Create the FilterConsumerInitEventArgs object for the 
        // FilterConsumerInit event.
        FilterConsumerInitEventArgs filterConsumerInitArgs = new FilterConsumerInitEventArgs();
        // Set the field names
        filterConsumerInitArgs.FieldList = _filterFieldNames;
        filterConsumerInitArgs.FieldDisplayList = _filterFieldDisplayNames;
        // return the FilterConsumerInitEventArgs.
