FieldGroupSelectorVisibility Property

Specifies whether to display the FieldLayout selector. It's a control that allows the user to change the current group of fields that are displayed in the FieldChooser.

Syntax

Visual Basic

'Declaration
 
Public Property FieldGroupSelectorVisibility As Nullable(Of Visibility)

C#

public Nullable<Visibility> FieldGroupSelectorVisibility {get; set;}

Example

The following code snippet enables the field chooser button in the data presenter and sets some of the commonly used properties in the FieldChooserOpening event. When the field chooser button is clicked, the data presenter displays a field chooser and raises the FieldChooserOpening event which lets you set properties on the field chooser that's about to be displayed.

For an overview of how to handle events in Visual Basic or Visual C#, see Event Handlers in Visual Basic and Visual C#. For specific information and code examples illustrating how to consume events in your application, see Consuming Events in the .NET Framework Developer's Guide.

        ' By defaults fields are displayed in alphabetical order. You can also display

This XAML snippet sets the HeaderPrefixAreaDisplayMode property to enable field chooser button and hooks into the FieldChooserOpening event.
