At ASP.NET application the server side code creates several input text boxes depending of the user’s request. The minimum number may be 0; the maximum depends of the number of matched records in a database. The names will be T1, T2, T3 … Tn. At the client side it is necessary to enumerate all those text boxes to perform some validations depending of the users actions. How it is possible to enumerate all existing input text boxes without knowing the exact number at the design time?
