Link ListBox With DataBase in Windows Forms

Here I will explain how to connect a ListBox with a database. It is the same as linking a combo box with a database.

Step 1: Form

Drag and drop a List Box from the Toolbox.

Step 2: Code

Now make a function for filling the list box from the database and call this method in the constructor.

 

 

void fillListBox()

{

    string str = "server = MUNESH\\SQL2008R2;Database=datastore;UID=sa;Password=123;";

    SqlConnection con = new SqlConnection(str);

    string query = "select * from tablename";

    SqlCommand cmd = new SqlCommand( query,con);

    SqlDataReader dbr;

    try

    {

        con.Open();

        dbr = cmd.ExecuteReader();

        while(dbr.Read())

        {

            string sname = (string) myreader["name"];; //name is coming from database

            Listbox1.items.Add(sname);

        }

    }

    catch(Exception es)

    {

        messagebox.show(es.Message);

    }

}

            

public Form2()

{

    InitializeComponent();

    FillListBox();

}

Step 3: Run

Now run your application.
