Disable Page Cache To Force Page Load With Browser Back Button
May 7, 2009
I have an asp.net website that is using update panels on the page that i cant get to reload from the server. I have this for the disable page cache on the master page.
When I click the browser back button to go back to the page it says the page has expired. the other pages on my web site work and call the page load, the only solution i found but cant use is to wrp the whole page in an update panel, but i cant do this becuase i have a report viewer on the page that does not work with ajax.
I'm working with the webbrowser control because I've had so many problems with using a non wrapped browser.
What I'm doing is filling out web forms, pressing submit, filling more information, etc etc. The problem is that when I press the submit but inside the code, the webbrowser doesn't actually reload the page so the second step of form filling can never happen.
From what I've read I think this is because it's simply loading from cache. Is there someway to stop this from happening such that when the submit button is pushed, and the server sends the new page, the webbrowser reloads it automatically?
What we want to do is save an entire control into Cache and recommit the properties on page load, including data items. But we'd like the controls to exist already in the page.
On my current project I want to deny going back once my customers hit submit button and redirected to the final page. How can I deny from going back to previous page or some mechanism to expire the page if the back button is clicked. I tried this code and it didn't work.
I am using an image button and on click of it i want to go to visited page.Now i am using - Response.Redirect(Request.UrlReferrer.ToString()),It is going to previous page, but when i am in a page of some user details where the link is looks like - users.aspx?userid=25 and i visit some other page and click back(image button) i want to see the same userdetail page. How to track that.
Does anyone know why a Page_Load would be called twice on a page when requesting an aspx page?I am using .Net 2.0 with the new .net 1.1 compilation model installed. Whenever I request a page, the Page_Load on the aspx page appears to be called twice, so does the Page_Load on and user controls added to that page.
I have a web app that has a base page.Each page needs to inherit from this base page as it contains properties they all need as well as dealing with the login rights.My base page has some properties, eg: IsRole1, IsRole2, currentUserID, Role1Allowed, Role2Allowed.On the init of each page I set the properties "Role1Allowed" and "Role2Allowed".[code]Should this functionality be in the base page or should it somehow be in the master, and if so how would I get access to all the properties if it was?As there are multiple people working on this project and creating pages some are forgetting to inherit from this basepage, or call the base pageload when overriding it.Is there any way to force them to do this?
I want to load a page in web browser and wnat to search for particular field, as soon as i get that field i want to stop navigation of that page.. how can i achieve it?
i am new to wpf and i try out navigation but i want some help when we navigate to a page other than the main page then its gonna have a back arrow in the top corner visible allowing to go back but i want that it should be hidden
I have an aspx page with three web controls: one to control the List Users page, one to control the Edit Users page, and one to control the Add User page. I have discovered a method for accessing these elements, but it seems to be limited. Here is what I have done:
Protected Sub editUser(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewEditEventArgs) 'set selected user from gridview.
[Code].....
This works in most cases. However, I am unable to access the "enabled" attribute of these web controls. Why is this, and how might I access that attribute?
If you do a search for "ie8 back button disabled" you'll see a number of blogs with people having difficulties with the Internet Explorer version 8 back button becoming disabled. This now happened to one of my ASP .Net pages. The page uses a user control, aspx page, and a master page. It uses no redirects and seems to be happening when I click the back button and then the forward button (after the forward button is clicked, it does not fire the Load event and the back button becomes disabled).
I have made many web browsers that just navigate to a web page, I don't have any buttons or any thing like that as it is controlled via other software using shortcut keys etc.I have created a button in my other software that sends the keys strokes "Control" and "H" I can get this to navigate to a webpage by manually typing i the same page that it navigates to when the form loads, but this mean I have to type the address in twice for each browser I make. I first type the url for the browser to navigate to in the properties section in VB and this is nice and quick to type in each webpage and build quickly build a new browser for it. Currently I have to repeat that url in the browser_homebutton Private Sub, what I want to happen in the below Private Sub is that it navigates to what ever address is typed in the "URL" cell in properties of the browser. What should my "Then" statement say? [code]
making verified accounts for my marketing and now I am hooked into improving as it is turning into a very good program I am just stuck with one thing which I can see being a very simple solution but I have search forum after forum and tonnes of Google searches all worded different to solve my my.It really is simple at present I use different buttons to automate different parts/pages of the account creation I am now setting it up so I click say for example a "go" button and it fills in the first page (and heres where I'm stuck waits for a specific url or even just a new url to load before continuing with the next bit of code
I have a page to which i send some variables with the GET method. In my VB back-end i get those variables using Page.Request.QueryString("<name>")If i then use the IsNumeric method to make shure it is an numeric string i get True back as value.
When i then try to transform the string to an Integer using val, cìnt, Integer.Parse or cType I get an error saying that my string could not be converted to a integer.So i made an error page which gives me all the info i need to deal with the problem (view below) Exception Message: Conversion from string "" to type 'Integer' is not valid.
[Code]...
IsNumeric confirms that it is a numeric string and that it should be convertable to an Integer. So why won't it work. I don't think that my code should provide any extra information because it only gets the querystrings, uses IsNumeric and then tries to convert them.
1. Is there any way to disable refreshing in such a way that the button can still be used for stuff like flash on the page still? All my methods have blocked using the button in the flash which is loaded on the page....
2. Is there any way to get the new scrollbars of IE10 or metro style scrollbar or what not into the webbrowser like the desktop version of IE10 does in Windows 8 Consumer Preview?
3. Is there any way to allow the close window called from javascript to be detected & actually close the window in my program?
4. Is there any way to make it so when new window is called it will open a new window with my application in a new instance? stopping me now is it seems to want to open in the same window if I use the event NewWindow to cancel the event from happening but it gets script errors....is there any way to retrieve the link to what it needs to open so I can handle this properly? Or at least tell it what else to use? besides the default browser....I want it to open inside my own program & not IE.
I have a popup aspx page that receives data from a parent page gridview Edit click. There is a great deal of parsing of data from parent page to pop up as the data is being translated in pop up, then sent back to parent page to be reassembled in the original text block before update.
When the popup passes the data back or is canceled, the parent page gridview is still in Edit mode.I would like to pass the Cancel or Update button click from the popup to the parent page gridview so it can complete the update or cancel event without asking the user to click the corresponding command button link from the gridview edit mode, to Update or Cancel.
UPDATE: There is also a jquery UIBlocker on the Parent page to prevent the user from returning to the page until the PopUp page processing has been completed. Below is the critical code:
PARENT Page: function parentFunc(a) { // Unblocks on return from popup page. $.unblockUI({});
[code]...
Had a problem with preventing the popup from reloading. So there is an if condition in the load event. A dynamic number of controls are built on the popup as literals. So the Page Init event and Page Load event fire on non Postback to rebuild the controls.
I have a page that add Items to RadioButtonList with this code :
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) RD.Read() RBQ1.Items.Add(RD.GetString(3))
[code]....
When I click in any button in the same page, the entire page reload and it display 8 items in the RadioButtonList, If I click for the second time I get 12 items in the RBL...How can I prevent the page to reload if I click in this button. ?
I am using <%@ MasterType virtualpath="~/__.Master" %> to embed my master page content into child page to access control belong to Master Page. I have one DropDownList in Master page. And I want to access its SelectedValue in my Child Page.
Problem is when page first time loads and as I am trying to access DropDownList's Selected Value by writing in child Page - "Master.DropDownList.SelectedValue". I am not able to get DropDownList's Value. Its display's Blank.
But When Page.IsPostBack I am able to get SelectedValue of that DropDownList.
I have managed to automate the following page: https://post.craigslist.org/atl/S/msg/none/x and even click the "Continue" button, but I noticed that my vb 2008 program is creating an infinite loop and tries to click "Continue" buttons on following pages. I only want my program to click the continue button once, fill out more data on the next page and then click another continue button on a later page. But I need the following code to end on the first page before I can continue coding for the following pages so that the web browser doesn't go crazy.Here is the code that I am using and not sure if this is called an infinite loop, but that is what it seems to be doing:
theElementCollection = WebBrowser1.Document.GetElementsByTagName("button") For Each curElement As HtmlElement In theElementCollection If curElement.GetAttribute("value").Equals("Continue") Then[code].......

I've noticed that when I Response.Redirect to an .aspx page, it sometimes displays a cached page instead of actually executing the page and pulling fresh data from the database. I'm not using output caching or anything special in .Net here -- this is a CRM, and the caching is either happening on the client or, perhaps more likely, automatically in IIS. There is never a querystring involved, by the way. I'm passing a key via session. I know that if I used the querystring it would probably partially bypass the cache problem, but it's not an option in this case.
I did a little digging, and some people get around this by using Server.Transfer (which actually behaves differently than Response.Redirect and some of the details are not always desirable), and some other people said to set Response.Cache.SetCacheability(HttpCacheability.NoCache) on the page where I want to avoid caching. I thought .aspx pages were always flagged to avoid caching. Right?
My page is loading to slowly, i am loading information from 2 giant dataviews, to get infromation about sales history, into a table. I am loading the information based on yesterdays sales/numbers.
I want to cache the data, but how could i do it if my query depends on the year selected, and the information the user wants. I was thinking it would be best to cache the pages. [code...]
I have a search page with a couple of pulldowns. Dependig on the values of them I show a grid matching the searched criteria, basically a table with links the user can navigate to. My problem comes when the user wants to navigate back. At the moment I have a "Back" button which simply redirects the user to the initial search page. I think it would be a good improvement to have the values of the pulldowns filled in with the values the user selected, this way when he presses the "Back" button he would not have to restart the whole search process again.
I have a VB.Net project that creates a new Webbrowser instance which then navigates to a page in order to read the HTML into a variable ( then modify this before displaying in a visable webbrowser).The issue i have is that the webbrowser navigate just reads the page from the cache and does not read it from the server.
