如何在asp.net中创建可编辑的DropDownList [英] How to create a editable DropDownList in asp.net

问题描述

我想创建一个已经从数据库中获取的数据填充的下拉列表。

现在我想要的是同样的下拉列表是可编辑的，即我可以手动输入一些数据。 br />
我想要这样，如果数据库中没有任何特定数据，可以插入它，如果可用，可以选择它。



因此，下拉列表应该作为下拉列表和文本框。



上述要求是州和城市的页面。因为如果数据库中没有插入任何状态，则应插入城市作为其子项。



是否需要进一步澄清？





****重要****



我想要的是填充ddl从数据库和用户也可以输入一些数据。单击提交按钮时，必须将特定值插入数据库。如果选择了值，则应插入其ID和新项目，而不是新数据。

I want to create a dropdownlist that is already populated by the data fetched from the database.
Now what else I want is that the same dropdownlist is editable i.e. I can manually input some data.
I want to this so that if any particular data is not available in the database it can be inserted & if it is available it can be selected.

Thus the dropdownlist should work as dropdownlist as well as a Textbox.

The above requirement is of a page for state & city. Because if any state is not inserted in the database it should be inserted with city as its child.

Does it need any more clarification?


****IMPORTANT****

What I want is to populate the ddl from database & also an user can input some data. When clicked on submit button that particular value must be inserted into the DB. If value is selected its id & if new item than new data should be inserted.
