VaryByControl - ASP.NET

Justin Dutoit

Hey. Exp. folks, I need to know, does VaryByControl cache based on the user
control's properties, or on a server control inside the user control?
I've read two sources which say that
VaryByControl=" id" caches based on the properties of the user control, like

Public Property Something
Get
Set

I thought it was - if there is a server control in the user control like

<asp:textbox id="something" runat="server" />

then there is a cached version of the user control for every value entered
into the "something" textbox.

This is for exam prep, thanks for helping with a tricky Q.

I should have added the link to MSDN which seems to agree (end of 4th
paragraph)
http://msdn.microsoft.com/library/de...us/cpguide/htm
l/cpconcachingmul tipleversionsof usercontroloutp ut.asp
(pl paste the 2 bits together)

"If you set the VaryByControl attribute to MyTextBox, there will be a
version of user control output stored in the cache for every value that the
MyTextBox control receives."

Yet Transcender & MeasureUp both say that the caching is done on the
Properties of the User control, as in
Public Property Something
Get
Set
I'd appreciate it if someone could clarify the sentence on MSDN. Or maybe
they're both true ...

Thanks

Hi!

User Control, @OutputCache, and varying the cache by property value

by: Tom Kiefer | last post by:

Question: If I have an ASP.NET User Control which defines/exposes a property that the page can use to specify a mode or data subset for the control to use, is there a way to tell the @OutputCache directive to vary its cache based on that property value? I.e., I have: <my:control runat="server" id="mcOne" Flag="One" /> <my:control runat="server" id="mcTwo" Flag="Two" />

Caching DataGrid Page

by: Janaka | last post by:

Hi All, I'm having a problem with Page Output caching on a page that contains a DataGrid. Basically the page pulls up some data for sales information from the DB. Some of this has to be calculated on the fly when the request is made, and so I thought it would be ideal to cache the page for a set amount of time. I've placed the following at the top of my page: <%@ OutputCache Duration="160" VaryByParam="None" %> Now the problem is...

I'm trying to understand ASP.NET caching. I set the Page Output directive to VaryByParams= None and the duration = 60. Now whenever users hit my web app they can see each others data. Is there anyway to cache the page without this happening or am I using Page Output caching in the wrong situation? It's a data entry web app that I'm trying to increase the performance on.

Cache for asp.net user control

by: =?Utf-8?B?QmlsbHkgWmhhbmc=?= | last post by:

Here is a user control on the page, how do I cache it by user? Currently I think we could put a server control for example ID:textusername in the asp.net page whose value is username, so we can utilize Output cache with varybycontrol to control the cache. Queation: If this is right direction, does this control ID:textusername need to be in the user control or just in the asp.net page? How do I check if it has been cached successfully?
