what you want requires a bit of work but to get you started in the key up event of the text box you could do something like ths for(int i=0; i { if(ListBox1.Items[i].Text..Substring(0, TextBox1.Length) == TextBox1.Text) { ListBox.Items[i].SelectedIndex =i; break; } } what this will do is track the characters entered into the text box and select the list box item that matches the characters entered. Hope this helps you...

hi, If it is a winform app then 1. Use DataTable as a datasource for the listbox,set valuemember (eg Id) and displaymeber property (eg Name) as well. 2. Store that datatable in your program as global variable. 2. Add a keypress event handler for textbox and in keypress event and in that handler filter global datatable using Select method eg. DataRow[] drArr=dtGlobal.Select("Name='" + txt.Text + "'"); DataTable dtNew = new DataTable(); for (int i = 0; i dt.Rows.Add(drArr[i].ItemArray); now set dtNew as datasource of ListBox. listBox1.DataSource=dtNew. try it and tell me.
