AutomationElement.TryGetCurrentPattern Method

.NET Framework 3.5

Other Versions

Retrieves an object that implements a control pattern.

Namespace: System.Windows.Automation
Assembly: UIAutomationClient (in UIAutomationClient.dll)

Syntax

C++

JScript

public bool TryGetCurrentPattern(
	AutomationPattern pattern,
	out Object patternObject
)

Parameters

pattern: Type: System.Windows.Automation.AutomationPattern
The identifier of the control pattern to retrieve.

patternObject: Type: System.Object%
On return, the control pattern if it is supported; otherwise null.

Return Value

Type: System.Boolean
true if the pattern is supported; otherwise false.

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.

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;
}
