用户控件内部未触发按钮 [英] button not firing inside usercontrol

问题描述

大家好，


我有一个动态加载到页面中的用户控件....在用户控件中有一个按钮.单击该按钮时(save_click)单击事件未触发...在tat页面中触发了页面加载事件但不是tat按钮！！！任何建议frens ??

解决方案

在恢复viewstate之后动态添加的所有内容对于viewstate不存在，因此没有事件.您需要尽快添加.阅读有关视图状态管理和动态控件的信息.

受保护的void Page_Load(对象发送者，EventArgs e)

{
Button.Click + =新的EventHandler(Button_Click);

}

void Button_Click(对象发送者，EventArgs e)
{

ButtonClick代码.....
}

在窗体运行时添加按钮时，是否为该按钮的click事件添加了事件处理程序?

祝您编程愉快！

Hi all,


I have a usercontrol which is dynamically loaded into the page.... I ve a button inside the user control..On click of it button (save_click) click event not firing....Page load event is getting fired in tat page but not tat button !!! Any suggestions frens ??

解决方案

Anything that''s dynamically added after the viewstate is restored, does not exist for viewstate, and therefore has no events. You need to add it sooner. Read up on viewstate management and dynamic controls.

Call ur Button Click Event In your PageLoad


protected void Page_Load(object sender, EventArgs e)

{
Button.Click += new EventHandler(Button_Click);

}

void Button_Click(object sender, EventArgs e)
{

ButtonClick Code.....
}

when you are adding button on form run-time, Have you added Event-handler for click event of that button?

Happy coding!
:)
