Web Forms :: Enabling Client Caching Of Part Of A Page That Is Changing Often In Some Parts But Not Others?
May 24, 2010
Let's say you had a page like an eBay auction, where some of the content (top bidder, bids, history, etc) needed to be up to date but other sections would likely never change, like the description. I'd like to know the "right" method for getting that static section cached.
The "cheezy" solution would be to code it up in a separate javascript .js file as a bunch of "document.writeln()" calls, but that's plain evil and ugly.
If I made it a Content section of a master page, that might get it cached at the server, but the client has no way to know that this particular section of the page will never change.
I could IFRAME it but I don't always know the dimensions.
I'm sure this has all been done before, and as much as I love my own wheels, I'd rather not reinvent this one :-)

I've seen a number of options for adding GZIP/DEFLATE compression to ASP.Net MVC output, but they all seem to apply the compression on-the-fly.. thus do not take advange of caching the compressed content.
Any solutions for enabling caching of the compressed page output? Preferably in the code, so that the MVC code can check if the page has changed, and ship out the precompressed cached content if not.
This question really could apply to regular asp.net as well.

i have a situation like this, hope u can help me sort it out.
I am going to develop a portal by using all web part page and many customize web part.
BUt the personalization of the web part layout only allow modify by administrator, that means the web site is not going to personalize by public user even in drag and drop function. They just can see a normal web site..
So, in the web config file, what should i set so that the authenticate administrator can change it to effects all the user.

As per requirement I disabled all validation controls in page on PageLoad event in server side.
On clicking submit button I want to activate them and validate the page and if the page is ok submit other wise not.
I am able to enable all validaters but one thing that I am unable to understand is that they do not validate the page. I set alerts and check they are being enabled but they do not validate the page and let the page submit.
Below is my script:

I have a few pages that are completely static. They only change at build time. But they are expensive to create. For the ones that are kind of expensive to create, I cache them for very long times using the ASP.NET output caching. But for one page, I really want it cached forever and ever or until the the next build.
What is the most expedient way to make this happen? Is there a build in feature that achieves this or a 3rd party tool?
(yeah, for the moment I plan to do the "view source" and copy paste thing, which isn't a very elegant build step)

I have a page with outputcache right above the action in a controller class. What I want is to disable this outputcache for myself. Can it be done by IP?
Something like that: [OutputCache(Duration = 60, VaryByParam = "None", IgnoreIP = "100.100.100.100")]

it is possible to cache an ASP.NET UserControl on the Client.
I have an User Control that queries a DB and renders a GridView. It must be on the Client because the query results vary from user to user (by the User.Identity.Name).

Our web app currently under development has authentication on all the pages.
We can deny a user access to any particular page but have found that if a user had previously opened the page that they can still access the page via the url. [Even if they log out and log in]
Assuming that the page is coming from client cache [Ctrl F5 in IE kicks in the proper authentication behavior or clearing the client cache]
A lot depends on how we have implemented the authentication but a quick fix on our side would be from within the admin section where we deny access to certain pages that we expire client cache for that page.
Is there a way to do this programmatically.
This would mean that client caching would continue to work as normal for all other users that still had access to the page in question.

I am trying to disable and enable hyperlinks on an aspx page using a button from another aspx page. I have an idea of having two buttons on one page labelled "disable" and "enable". clicking disable should disable a particular link on another page and clicking enable should enable that same link.

I have an HTTPHandler that returns some XML. I am trying to figure out how to get this to cache in the browser, as if it were a static XML file.
I've tried this along with a few other variations and other Cache options, but nothing I do seems to make it cache (according to Fiddler).
how I can cache the output on the client's browser?

I've been working on a task to add a validator to compare the values of two text fields in a ASP.NET 1.1 application.
It uses validators already, so the best approached seemed to involve a CustomValidator. I was inspired by the following example:
[URL]
I got the server side validation working - now I'm trying to add some client-side validation but I'm having a strange issue.
When I click in either of the two text fields, the value of the txtFinalGrade field is overridden to either "true" or "false". I've been having a tough time tracking down the code that's causing this. I tried using the IE Developer Toolbar to trace the script - as well as FireBug in Firefox (though this is an IE-only app) and I'm still trying to figure out what's causing this to happen.
Since I think this is a JavaScript issue, I'm posting that part of my code:
[Code]....
Anyone have ideas of things to try? Anyone have similar issues with textboxes being set to true/false when working with custom validators?

I am working on a VWD Walkthrough: Creating a Web Parts Page in VWD, [URL]Here I created a user control, DisplayModeMenu.ascx. Somehow, when running this webpage, the DropDownList of this user control showed only a Browse selection, no Edit selection. Clicking the "Reset User State" link showed the following error message.
The Walkthrough did not list any information on setting up the "ASP.NET Web Site Administration Tool" or additional tags on Web.config. How can I fix the errors?
BTW, is it true that User Control is not recommended for VS 2005/8 any more.
Personalization is not enabled and/or modifiable. The Enabled property must be set to true, and a registered personalization provider must be selected. The current user must be granted the right to modify personalization state.

My Project is a normal web site, not a Web Project, and I am using VS 2005.
I am trying to define common Master Page Type in app_code which has an area to display error messages and the like. Very simple.
I added the following in app_code:
[Code]....
Also, I added the following in Master Page Source Declaration:
[Code]....
Also, I added the controls tblrowErrMsg and lblErrMsg as server controls to the Master Page.
Why I am doing this ?
This will allow me to display error messages from nearly any where inside the code in code-behined, app_code, and other core Class Projects (DLL).

Assuming that I can't modify the code-behind file for a site (it's a compiled site), I've encountered a bug of mine that can only be fully fixed with a complete recompile and redeployment. Unfortunately, we are on a strict release schedule and we can't deploy for another 11 days.
The bug is that I'm doing a check on a drop down to make sure that the value that is selected isn't "-1". However, I didn't use drp.SelectedItem.Value, I used drp.Items[0].Value. Total bonehead move on my part. The bottom line is that drp.Items[0].Value is ALWAYS -1, so they page gives an error to the user stating that they need to choose an option for that drop down. Which they really have, but my bug is not letting them continue in this process.
So, I'm trying to determine if I could, client-side, replace the value of the first drp item to the actually chosen value of that drop down.
I've gotten this all to work client-side, but when the form is posted back, the value is still the value that was populated from code, meaning "-1".
I'm sure this is because the drop down is loaded and all the values are held in ViewState.

i want to update different areas of my MVC page after one action (say a click) occurs.
how, i use ajax, and wrapping the entire area where all these parts need to be updated is counter intuitive as the ajax data being sent back would be close to the entire page.
so, i have a few partial views, - but the problem is, each action only returns one view! how can i return multiple views from this one action?
i know a popular solution is to just hammer the server with multiple async javascript ajax requests for each "part" of the view, but this really is unnecessary and inefficient, reconstructing and destroying the page (say) 5 times for just one action, when it should just occur once, and once it does, the server should manage all the partial views then and there.

What I'm trying to achieve is basically to prevent client-side change of the state of my server controls.
For example, let's say that I have a business web applications, that shows some data in read-only fashion to the regular users, but allow the admin to edit the data. In such case I use regular ASP.NET server controls, but disable them for the regular user (enabled=false). The problem that I have is that any advanced user could change the disabled control on the client using short javascript code and check the supposedly disabled and unchecked checkbox.
what is the easiest way to prevent this client-side change. I thought that when the control is disabled before rendering the page, the following postback would not touch this control at all, no matter how you change it on the client. Did I get terribly wrong?

I am setting up an asp.net web parts portal for some stuff. I have a [hopefully] really easy question. How can I make the page have 3 major columns?
Right now I have two columns using <div id="leftpanel" style="float: left"> and <div id="rightpanel" style="float: right">. But I cannot figure out how to get a panel in the center. The right panel is basically in the center and there is not a css float: middle/center. So how is a three panel web parts page accomplished?
