One of the nicest features in visual studio
controls is the ability to auto compete what we are typing in ComboBox and other
controls, that what I will to explain to use it efficiently.
1. Let's create the following UI :
![Image1.png]()
2. Make the following changes :
ComboBox1
Set comboBox1 property : AutoCompeteSource
to ListItems
Set comboBox1 property : AutoCompeteMode
to SuggestAppend
Fill the items list of the comboBox1 by :
Algeria,Maroco,Tunisia,Egypt,France,Italy,Germany,,India,China
ComboBox2
Set comboBox1 property : AutoCompeteSource
to CustomSource
Set comboBox1 property : AutoCompeteMode to SuggestAppend
And leave the items list blank
The code behind the form:
using
System;
using
System.Collections.Generic;
using
System.ComponentModel;
using
System.Data;
using
System.Drawing;
using
System.Linq;
using
System.Text;
using
System.Windows.Forms;
namespace
ComboBoxAutoComplete
{
public partial
class Form1 : Form
{
//create a list of strings to use as
custom Autocompete source with combobox2
List<string>
customSource = new
List<string> {
"Algers", "Paris",
"Tokyo", "Rome"
};
public Form1()
{
InitializeComponent();
}
private void
Form1_Load(object sender,
EventArgs e)
{
//assign the list to
AutoCompleteCustomSource of the combobox2
comboBox2.AutoCompleteCustomSource.AddRange(customSource.ToArray());
}
}
}
So what do we have done.
For the comboBox1 it auto completes from the
its list Items using the mode SuggestAppend and it is not necessary to use it
you can try the other options.
The comboBox2 uses a string list to auto
complete .
