AutoComplete TextBox Control

Question

I want to have a textbox control that suggests and append values from a database in a Windows application with C# 2008 and LINQ.

I do it with a combobox but I can\'t

Answer 1

Check out the AutoCompleteSource, AutoCompleteCustomSource and AutoCompleteMode properties.

textBox1.AutoCompleteMode = AutoCompleteMode.Suggest;
textBox1.AutoCompleteSource = AutoCompleteSource.CustomSource;
AutoCompleteStringCollection col = new AutoCompleteStringCollection();
col.Add("Foo");
col.Add("Bar");
textBox1.AutoCompleteCustomSource = col;

Note that the designer allows you to do that without writing any code...
