Now difficult to accurate and practical demo this kind of development, and 2010 years ago asp.net estimates a bookstore, including what book "asp.net development of OA system", it should have a code example of that era,

For example the asp.net tutorial https://blog.csdn.net/heker2007/article/details/1522564 of this series is very suitable for asp.net 2.0 introduction of amateur study before 2005, when the authors do not know - at least not involved - later, technology development, basically not suitable for development programmers learn learned asp.net controls, also does not fit after 2006 asp.net altas project after 3.0 and asp.net technology,

Two cascade dropdownlist do right? Put the second dl data binding in the first indexchange incident, the second event of dl label values are not to go,

CodePudding user response:

Is not a simple level, since the first Ddl is created dynamically, the second, third and dynamically created, now is the first selectedindexchange how dynamic events to write or binding

These can use js ajax to achieve, if you will only drag control, then you can write some small toy nature of the program,
