I have 2 textboxes tb1 and tb2. When I change a value in tb1, it retrieves data from the database based on the entered value for tb1 and displays the retrieved data in tb2. This is done asynchronously. I use UpdatePanel for that. But I wonder if there's a better way to do it such as using webservice. If yes, how can that be done? AutocompleteExtender and CascadingDropDown controls allow you to specify a ServiceMethod to retrieve data from database. Since I'm not using any of these 2 controls, I don't know how to specify a ServiceMethod for the textbox.
