Gets or sets a value specifying the source of complete strings used for automatic completion.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
public function get AutoCompleteSource () : AutoCompleteSource public function set AutoCompleteSource (value : AutoCompleteSource)
Use the AutoCompleteCustomSource, AutoCompleteMode, and properties to create a ComboBox that automatically completes input strings by comparing the prefix being entered to the prefixes of all strings in a maintained source. This is useful for ComboBox controls in which URLs, addresses, file names, or commands will be frequently entered.
You must use the AutoCompleteMode and properties together.
If the list of strings is empty, pressing the BACKSPACE or DELETE key does nothing.
If the BACKSPACE key is pressed in less than one second, the previous item is selected, or nothing is selected if the list of string is empty.
If the BACKSPACE key is pressed in more than one second, the first item is selected.
If the DELETE key is pressed, the first item is selected.
The operating system might limit the number of custom strings that it can display at once. For strings that contain a forward slash (/) or backward slash (\), automatic completion appends all characters only up to and including the slash.
