 bool TryGetCurrentPattern(System::Windows::Automation::AutomationPattern ^ pattern, [Runtime::InteropServices::Out] System::Object ^ % patternObject);

public bool TryGetCurrentPattern (System.Windows.Automation.AutomationPattern pattern, out object patternObject);

member this.TryGetCurrentPattern : System.Windows.Automation.AutomationPattern * obj -> bool

Public Function TryGetCurrentPattern (pattern As AutomationPattern, ByRef patternObject As Object) As Boolean

Parameters

pattern: AutomationPattern

The identifier of the control pattern to retrieve.

patternObject: Object

On return, the control pattern if it is supported; otherwise null.

Returns

Boolean

true if the pattern is supported; otherwise false.

Examples

The following example shows how to use this method to retrieve a control pattern.

// element is an AutomationElement.
object objPattern;
SelectionPattern selPattern;
if (true == element.TryGetCurrentPattern(SelectionPattern.Pattern, out objPattern))
{
    selPattern = objPattern as SelectionPattern;
}

' element is an AutomationElement.
Dim objPattern As Object = Nothing
Dim selPattern As SelectionPattern
If True = element.TryGetCurrentPattern(SelectionPattern.Pattern, objPattern) Then
    selPattern = DirectCast(objPattern, SelectionPattern)
End If

Remarks

For some forms of user interface (UI), this method will incur cross-process performance overhead. Applications can concentrate overhead by caching patterns and then retrieving them by using GetCachedPattern.
