code-behind

问题 everyone, thank for your time.

问题 I want to copy a List of Objects, but i keep getting references between the objects. List<MyClass> copy = original; When i change the value in the copy List, the original List ends up modified also. Is there a way to work around it? 回答1: You can do this: List<MyClass> copy = original.ToList(); This would make an element-by-element copy of the list, rather than copying the reference to the list itself. 来源： https://stackoverflow.com/questions/15330696/how-to-copy-list-in-c-sharp

But my requirement is to be able to create viewbox in code behind and assign it the properties. <WrapPanel x:Name="_wrpImageButtons" Grid.IsSharedSizeScope="True"

问题 in my web application if the user leaves the current page without having saved changes in the form a pop up window is opened to alert him about that.

I tried like: var button

问题 This is probably going to boil down to a philosophical question more than anything, but is there really any major difference between using the <asp:sqldatasource> in the aspx file versus doing all of the work in the code behind?
