从下拉列表中获取文本框中的值

Question

I have a textbox named textbox1 and a dropdownlist. Dropdownlist contains the list of branches and i want that when i select a branch from dropdown i want to get the respective branch code to be generated in a textbox from the Database or from c# coding. How will it be possible ?

Answer 1

我是否想念一些东西，是否只是将事件处理程序放在下拉列表中，以使其在值更改时调用您的方法，该方法可以执行生成文本框字符串所需的任何操作，是否更复杂？

Answer 2

Skipping passed the "database" portion of your question (and assuming your data isn't bound to the DropDownList)..

One way in ASP.NET, to accomplish this, I believe, is to have your code print DropDownList.SelectedValue's value in the textbox during an event.
