Namespace: System.Activities.Design.PropertyEditing
Assembly: System.Activities.Design.Base (in System.Activities.Design.Base.dll)

Syntax

'Declaration
Public Overridable Sub ShowDialog ( _
    propertyValue As PropertyValue, _
    commandSource As IInputElement _
)
'Usage
Dim instance As DialogPropertyValueEditor
Dim propertyValue As PropertyValue
Dim commandSource As IInputElement

instance.ShowDialog(propertyValue, commandSource)

public virtual void ShowDialog(
    PropertyValue propertyValue,
    IInputElement commandSource
)

public:
virtual void ShowDialog(
    PropertyValue^ propertyValue, 
    IInputElement^ commandSource
)

public function ShowDialog(
    propertyValue : PropertyValue, 
    commandSource : IInputElement
)

abstract ShowDialog : 
        propertyValue:PropertyValue * 
        commandSource:IInputElement -> unit 
override ShowDialog : 
        propertyValue:PropertyValue * 
        commandSource:IInputElement -> unit

Parameters

propertyValue
Type: System.Activities.Design.PropertyEditing.PropertyValue
The PropertyValue for the property being edited.

commandSource
Type: System.Windows.IInputElement
The IinputElement that can be used as a source for execution of PropertyValueEditorCommands.

Remarks

Since the commands get handled by the host and since custom dialogs are not going to be part of that visual tree, the commandSource exposes an IInputElement that is part of the host's visual tree and that, therefore, can be used to execute property editing commands in such a way that they are handled correctly. Overriding this method enables you to implement any custom dialog logic, such as invoking existing system dialogs.
