hi there
i'm a begginer in c#
i need to create a textbox onkeypress..
i have a dynamic list of courses...
i need the first charachters that typed in the textbox will find those courses with names that begins with those charachters ...kind of filter...
and i need to do that on server side..not with javascript..
is this possible? and how can i do that...
this is a web application ..
thanks to all answers...
pleaase show me how to do this in syntax...on client and server...

I first make a list.
when the text change in the textbox then I will check if the chars are the same.
To check if it works I print all the possible strings in a listBox.
I hope that you can use this, if you can vote than aub!

namespace WindowsFormsApplication2
    public partial class Form1 : Form
        List<string> dinosaurs;
        List<string> dinosaurs2;

        public Form1()
            string[] input = { "Brachiosaurus", 

          dinosaurs = new List<string>(input);


        private void txt_write_TextChanged(object sender, EventArgs e)
            dinosaurs2 = new List<string>();
                for (int x = 0; x < dinosaurs.Count; x++)
                    if (dinosaurs[x].Substring(0, txt_write.Text.Length) == txt_write.Text.Substring(0, txt_write.Text.Length))

          listBox1.DataSource = dinosaurs2;
