  • Reference

Definition

Namespace:
System.Windows.Automation
Assembly:
UIAutomationClient.dll

Identifies the IsContentElement property.

public: static initonly System::Windows::Automation::AutomationProperty ^ IsContentElementProperty;
public static readonly System.Windows.Automation.AutomationProperty IsContentElementProperty;
 staticval mutable IsContentElementProperty : System.Windows.Automation.AutomationProperty
Public Shared ReadOnly IsContentElementProperty As AutomationProperty

Field Value

AutomationProperty

Examples

The following example retrieves the current value of the property. The default value is returned if the element does not provide one.

bool isContent = (bool)
   autoElement.GetCurrentPropertyValue(AutomationElement.IsContentElementProperty);

Dim isContent As Boolean = CBool(autoElement.GetCurrentPropertyValue(AutomationElement.IsContentElementProperty))

The following example retrieves the current value of the property, but specifies that if the element itself does not provide a value for the property, NotSupported is to be returned instead of a default value.

bool isContent1;
object isContentNoDefault =
    autoElement.GetCurrentPropertyValue(AutomationElement.IsContentElementProperty, true);
if (isContentNoDefault == AutomationElement.NotSupported)
{
    // TODO Handle the case where you do not wish to proceed using the default value.
}
else
{
    isContent1 = (bool)isContentNoDefault;
}

Dim isContent1 As Boolean
Dim isContentNoDefault As Object = autoElement.GetCurrentPropertyValue(AutomationElement.IsContentElementProperty, True)
If isContentNoDefault Is AutomationElement.NotSupported Then
    ' TODO Handle the case where you do not wish to proceed using the default value.
Else
    isContent1 = CBool(isContentNoDefault)
End If

Remarks

This identifier is used by UI Automation client applications. UI Automation providers should use the equivalent identifier in AutomationElementIdentifiers.

This property can also be retrieved from the Current or Cached properties.

The content view of the UI Automation tree provides a view of the UI that only contains elements that represent data within the UI.

An element must be a control to be able to hold content.

Return values of the property are of type Boolean. The default value for the property is true.
