Solution 1

Try this:

C#

public Form1()
{
    InitializeComponent();
    yourTextBox.AutoCompleteMode = AutoCompleteMode.Suggest;
    yourTextBox.AutoCompleteSource = AutoCompleteSource.CustomSource;
    AutoCompleteStringCollection source = new AutoCompleteStringCollection();
    source.AddRange(new string[]
                    {
                        "Item1",
                        "Item2",
                        "Item3"
                        // add more items if you want
                     });
    yourTextBox.AutoCompleteCustomSource = source;
}

Hope this helps.

quite good but "item1" i need to add manually which is really time consuming if i have 30 thousand records

Thomas Daniels 29-Sep-13 13:43pm

You don't have to add them manually. You can read the records from a file, or from a database. The only thing you need is a string array that you can add to the source variable.

can you give me demo?? with datbase

Thomas Daniels 30-Sep-13 10:38am

Not exactly, because I don't know your database settings such as:
1. Connection String
2. Type of database
3. Column names

Reading from database is not very hard, I suggest you to go through the following links:

i familar with ado.net but don't know what to write instead of item.... ?? query??? or what???

Thomas Daniels 30-Sep-13 12:09pm

The query should be:
SELECT ColumnNameHere FROM TableNameHere

Muhamad Faizan Khan 30-Sep-13 12:25pm

oh simple it means

public Form1()
{
InitializeComponent();
yourTextBox.AutoCompleteMode = AutoCompleteMode.Suggest;
yourTextBox.AutoCompleteSource = AutoCompleteSource.CustomSource;
AutoCompleteStringCollection source = new AutoCompleteStringCollection();
source.AddRange(new string[]
{
"Select columns from table"
// add more items if you want
});
yourTextBox.AutoCompleteCustomSource = source;
}

is this ?

Thomas Daniels 30-Sep-13 12:27pm

No, "Select columns from table" is the SQL query that you need to execute on the database.

Muhamad Faizan Khan 30-Sep-13 12:37pm

then what to write between range
source.AddRange(new string[]
{
????
// add more items if you want
});

Thomas Daniels 30-Sep-13 12:40pm

First, store the contents of the database inside a string array. And then, add this string array to the source:


string[] content = // retrieve from database
source.AddRange(content);
