TaskPaneCollection class

Office 2013 and later

Contains a collection of TaskPane objects that represent the task panes associated with a window in Microsoft InfoPath.


Namespace:  Microsoft.Office.InfoPath
Assembly:  Microsoft.Office.InfoPath (in Microsoft.Office.InfoPath.dll)

public abstract class TaskPaneCollection : IEnumerable

The TaskPaneCollection class provides properties that can be used to access TaskPane objects, and it is accessed through the TaskPanes property of the Window class.


The TaskPaneCollection class can be used only to get the count of the TaskPane objects that it contains and to return a reference to a specified TaskPane object. It cannot be used to add or remove TaskPane objects.

The following example sets a reference to the TaskPane object in the TaskPaneCollection with the index value of 1, which corresponds to the Clip Art task pane, and then displays the task pane.

TaskPane myTaskPane = this.TaskPanes[1];
myTaskPane.Visible = true;

Alternatively, you can reference a TaskPane object in the TaskPaneCollection by using a TaskPaneType value, as shown in the following example.

TaskPane myTaskPane = this.TaskPanes[TaskPaneType.ClipArt];
myTaskPane.Visible = true;

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
