下拉菜单文字框 [英] Dropdowns & Textboxes

问题描述

大家好，

需要您的惊人帮助；)

我有一个进入页面，其中包含许多下拉列表&文本框.

我希望能够从下拉列表的DepreciationRate中选择一个值，例如0.5％，然后在成本"文本框中输入一个成本价格"，当我这样做时，我希望能够进行快速计算并将答案放入另一个空文本中框，称为总折旧.

我已经尝试将DepreciationRate DDL中的选定值发送到文本框，然后使用该选项和Cost文本框从隐藏的文本框中进行计算，但是它不起作用.

这就是我的意思...

我的下拉列表也绑定到数据库.

多谢你们！感谢您的帮助.

Hey Guys,

Need your amazing help ;)

I have an entry page with a number of dropdownlists & textboxes.

I want to be able to select a value from the dropdownlist DepreciationRate e.g 0.5% then enter a Cost price into a Cost Textbox, when i do this, I would like to be able to do a quick calculation and place the answer into another empty text box called Total Depreciation.

I''ve tried sending the selected value from DepreciationRate DDL to a textbox, then do a calculation from a hidden textbox with that choice and the Cost textbox but it doesn''t work.

Here''s what I mean...

My dropdownlists are bound to a database also.

Thanks guys! Appreciate your help.
