具有新控件的asp.net工具包 [英] asp.net tool kit with new controls

问题描述

大家好，

在我们的项目中，我们使用具有不同验证的多个文本框.

例子
仅包含数字的textbox1
具有alpha数值的textbox2
具有电子邮件验证功能的te​​xtbox3
具有日期验证和日期选择器的textbox4.


我想在bulit中开发具有不同验证功能的控件.
如果我只需要带有数字的文本框，则可以将其拖放到我的应用程序中

任何人都可以引导我.


谢谢

推荐答案

通常，通过从TextBox继承并覆盖TextBox的OnKeyPress方法，可以防止在TextBox中输入任何键. 仅接受数字的文本框 [ CompositeControl [ ^ ]或 CustomControl [

Usually you can prevent any keys from being entered in a TextBox by Inheriting from a TextBox and overriding the OnKeyPress Method of a TextBox. Text box to accept only number[^] there is an example. Any other validation would work more or less the same.
For more advanced TextBoxes you might have to create a CompositeControl[^] or a CustomControl[^]. This can be quite a difficult and daunting task though.
