Returns a DataGridColumnHeaderAutomationPeer for use by the Silverlight automation infrastructure.
Assembly: System.Windows.Controls.Data (in System.Windows.Controls.Data.dll)
This method creates a new DataGridColumnHeaderAutomationPeer instance if one has not been created for the control instance; otherwise, it returns the DataGridColumnHeaderAutomationPeer previously created.
Classes that participate in the Silverlight automation infrastructure must implement this method to return a class-specific derived class of AutomationPeer that reports information for automation behavior.
For a list of the operating systems and browsers that are supported by Silverlight, see Supported Operating Systems and Browsers.
