textBox KeyPress event connect with listBox

Question

I have listBox and I Fill him with some values ( oleDbConnection1.Open(); OleDbDataAdapter DAProdukt = new OleDbDataAdapter(select ProduktIDProdName FROM ProductioleDbConnection1); DataSet DSProdukti = new DataSet(); DAProdukt.Fill(DSProdukti); listBox1.DataSource = DSProdukti.Tables[0]; listBox1.DisplayMember = ProdName; listBox1.ValueMember = ProduktID; ). Is it possible for example to start write in one textBox and in that textBox.Text to show the value from listBox.DisplayMember who have the same name before I write all name? If is not possible than how can I do that with comboBox1 when I start writing in him automatically to show the name from comboBox1.DisplayMember before I write all name? Thanks!!

Hi try this string currentName; for(int i = 0; i < lstNamed.Items.Count; i++) { currentName = lstNamed.Items[i].ToString(); if(currentName.StartsWith(txtName.Text)) { lstNamed.SelectedIndex = i; break; } } You may aslo get all the names that starts with the text in the text box say xy in the textbox and in list box xyz and xyw ) and sort them alphabetically and then select the first ... and u may aslo ignore the case difference ( case insensetivity lower or upper) and so on ... Good Luck
