问题描述

附加图像，请发现该图像中有一个添加客户端"选项，当我们单击该按钮时，将添加更多表(动态添加行).如果单击任何特定日期以将详细信息显示在网格视图行中，则还有一个日历工具，该文本框应仅接受数字值(字符从不显示).

我被带到了项目"文件而不是网站"，当我们检查文本框属性时有一个选项事件"，在事件"中没有按键"选项，因为我被带到了项目文件中.

Hi,
Attached the image, please find that, in that image there is a "add client" option is there , when we click that button more tables will be adding(Dynamically adding the rows). There is a calender tool is also there, if we click any particular date that details should be display in grid view rows.That text boxes should accepts only numeric values.(Characters never display).

I was taken "project" file not "Website" , when we check the text box properties there is an option "Event" , in "Event" there is no "Key press" option because i am taken project file . Is there any way to come out from this problem?

推荐答案

如果您正在开发一个网站，则TextBox不会发生事件"KeyPress".在Windows应用程序中可用.

If you are developing a website, TextBox does not have an event ''KeyPress''. It is available in Windows applications.
