firstly thank you so much for interest. yes i want o run an event of aspx without postback. so that possible with js. for example we have a textbox for check names in database, when we press 'a' i want to see all datas from db which start with 'a'.
I don't quite understand what you're trying to do. Let me see if I have this correct...
1. Have an ASP text box control on a form
2. The user enters text into the text box
3. Does the user have to press a button or is this on the TextChanged event?
4. Show all values from some database table where a field contains the text entered in the text box with no round trip to the server
