防止一个控件的页面生命周期

Question

I'm using a file manager-type WebControl that does lots of postbacks. It's placed inside a Page that is relatively complex. I would like to prevent the WebControl from causing the whole Page to go through the lifecycle. An UpdatePanel helps a little, but not enough.

Is there any way to isolate the WebControl from the rest of the Page ? The only way I can think of is sticking the WebControl in a separate Page and creating an iframe in the original Page . Unfortunately that also means my WebControl properties/settings are no longer in the original Page . If I want two instances of the WebControl with different settings, then I have to create a Page for each setting and reference the correct one in my iframes . Not quite as "drag & drop" as I would like. Any other suggestions?

Answer 1

Hard to tell, you can't prevent a control from going through lifecycle; is there anyway to identify though, that during a certain page postback, you prevent the code from running in each event handler by doing something like:

if (_shouldNotRun == true)
   return;

//Event handler code

Essentially, figuring out some way to indicate whether the control should run may be an option. IFrame would work, but yes you have to deal with the issues you mentioned. Can you give more detals to the problem?

HTH.

Answer 2

Not 100% sure what events possible to override that are called on PostBack. A good source for the Life Cycle of a page (http://msdn.microsoft.com/en-us/library/ms178472.aspx)

But it sounds as it would be better to remake your control to create Ajax webservice requests for the functions that are possible to prevent most of the postback's?
