Parameters

fieldLayout
Field layout for which the FieldChooser will be displayed. Can be null in which case the root field layout will be pre-selected and the user will be allowed to select a different field layout.
allowFieldLayoutSelection
Specifies whether the user will be allowed to change the field layout and select fields of a different field layout.
retainFieldChooser
Specifies whether the data presenter should retain the FieldChooser that's displayed so that it can reuse it the next time this method is called instead of having to create a new one. This also retains the state of the FieldChooser.
windowCaption
Specifies the caption of the window in which the FieldChooser is displayed. If null is specified the default caption is used. Specify empty string to not display any caption.
Remarks

ShowFieldChooser displays a FieldChooser that allows the user to select which fields of the specified field layout are displayed in the data presenter. The FieldChooser control will be displayed using a Infragistics.Windows.Controls.ToolWindow.

You can control aspects of the FieldChooser by hooking into FieldChooserOpening event. The associated event args provides the instance of the FieldChooser that will be displayed as well as the ToolWindow that will be used to display it.

Note that if the fieldLayout parameter is specified, the fields of that field layout will be displayed in the FieldChooser. Otherwise the root field layout's fields will be displayed. The AllowFieldLayoutSelection parameter specifies whether the the user will be allowed to change the field layout and select fields of other field layouts. FieldChooser's FieldChooser.FieldGroupSelectorVisibility property will be initialized based on that parameter.
