C# 클래스 System.Windows.Controls.AutoCompleteBox

Builds the visual tree for the T:System.Windows.Controls.AutoCompleteBox control when a new template is applied.

Notifies the T:System.Windows.Controls.AutoCompleteBox that the P:System.Windows.Controls.AutoCompleteBox.ItemsSource property has been set and the data can be filtered to provide possible matches in the drop-down.

Call this method when you are providing custom population of the drop-down portion of the AutoCompleteBox, to signal the control that you are done with the population process. Typically, you use PopulateComplete when the population process is a long-running process and you want to cancel built-in filtering of the ItemsSource items. In this case, you can handle the Populated event and set PopulatingEventArgs.Cancel to true. When the long-running process has completed you call PopulateComplete to indicate the drop-down is populated.

Arranges and sizes the T:System.Windows.Controls.AutoCompleteBox control and its contents.

Converts the specified object to a string by using the P:System.Windows.Data.Binding.Converter and P:System.Windows.Data.Binding.ConverterCulture values of the binding object specified by the P:System.Windows.Controls.AutoCompleteBox.ValueMemberBinding property.

Override this method to provide a custom string conversion.
