ICustomAction Interface (Deprecated)

This interface is deprecated starting from version 5.0. Use the ICustomActionEx Interface instead.

The ICustomAction interface is located in WA.Core.DLL that is installed in the Global Assembly Cache (GAC) when you install QuickApps for SharePoint.

The following is the signature of the WA.Core.ICustomAction interface:

public interface ICustomAction
{

    void Perform(HttpContext context,
    ICollection listItems,
    CustomActionCancelEventArgs evt);
}
