我有一个带有一列复选框的GridView(GridView的其余部分是从数据库填充的).我正在使用AJAX执行不同的功能，我想知道我是否只是没有在正确的位置调用OnCheckedChanged事件.它应该被包装在某种UpdatePanel中吗？我对这一切都还很陌生...基本上，我的目标是在选中复选框时更改数据库中的一个位值.我知道怎么做的逻辑，我只是不知道我是否以正确的方式处理了OnCheckedChanged事件.
.CS
protected void CheckBoxProcess_OnCheckedChanged(Object sender, EventArgs args)
{
CheckBox checkbox = (CheckBox)sender;
GridViewRow row = (GridViewRow)checkbox.NamingContainer;
OrderBrowser.Text += "CHANGED";
}
}
