ToolStripTextBox.AutoCompleteSource Property

Gets or sets a value specifying the source of complete strings used for automatic completion.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

[BrowsableAttribute(true)]
public AutoCompleteSource AutoCompleteSource { get; set; }

Property Value

Type: System.Windows.Forms.AutoCompleteSource
One of the AutoCompleteSource values. The default is None.

Use the AutoCompleteCustomSource, AutoCompleteMode, and AutoCompleteSource properties to create a ToolStripTextBox 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 ToolStripTextBox controls in which URLs, addresses, file names, or commands will be frequently entered.

The use of the AutoCompleteCustomSource property is optional, but you must set the AutoCompleteSource property to CustomSource in order to use AutoCompleteCustomSource.

You must use the AutoCompleteMode and AutoCompleteSource properties together.

The following code example demonstrates the syntax for setting various ToolStripTextBox common property settings, including the AutoCompleteSource property .

// This code example demonstrates the syntax for setting 
// various ToolStripTextBox properties. 
// 
toolStripTextBox1.AcceptsReturn = true;
toolStripTextBox1.AcceptsTab = true;
toolStripTextBox1.AutoCompleteCustomSource.AddRange(new string[] {
"This is line one.",
"Second line.",
"Another line."});
toolStripTextBox1.AutoCompleteMode = System.Windows.Forms.AutoCompleteMode.SuggestAppend;
toolStripTextBox1.AutoCompleteSource = System.Windows.Forms.AutoCompleteSource.CustomSource;
toolStripTextBox1.BorderStyle = System.Windows.Forms.BorderStyle.FixedSingle;
toolStripTextBox1.CharacterCasing = System.Windows.Forms.CharacterCasing.Upper;
toolStripTextBox1.HideSelection = false;
toolStripTextBox1.MaxLength = 32000;
toolStripTextBox1.Name = "toolStripTextBox1";
toolStripTextBox1.ShortcutsEnabled = false;
toolStripTextBox1.Size = new System.Drawing.Size(100, 25);
toolStripTextBox1.Text = "STRING1\r\nSTRING2\r\nSTRING3\r\nSTRING4";
toolStripTextBox1.TextBoxTextAlign = System.Windows.Forms.HorizontalAlignment.Center;
