So basically here I am trying to wait for my server to connect to my website signaling it that its done and so the page needs to be refreshed(cause sql was updated). Thing is when I try to use the response/request in the thread it simply doesn't want to work.
Here the code
Code:
[code]....
Errors I am getting are:
1. If I have the headers clear thing there it gives requires integrated IIS pipes or something like that.
2.If I don't have the clear headers it says the headers were already sent.
I want to remove checked items from checklistbox (winform control) in class file method which i am calling asynchronously using deletegate. but it showing me this error message:-
Cross-thread operation not valid: Control 'checkedListBox1' accessed from a thread other than the thread it was created on.
i have tried invoke required but again got the same error. Sample code is below:
I have a table on my page. I need to scroll down a little to get to that table. In that table i have som data that i edit and save to database. When the save is done i need to refresh the page( Response.Redirect(Request.RawUrl )) so it loads the new data to that table. When the refresh is done the page is on top again so that i need to scroll down again to see the table. This makes it very unusable for the user.
How can i refresh the page without it going back to top again? I tryed wrapping an updatepanel around the table but it didnt
I'm new to threading and have used it successfully, but limited. I can spawn a thread and have the main thread reference variables in the spawned thread, but I don't know how to allow the spawned thread to reference (and update) variables in the main thread.
Any example threading code I've seen on the web appears to be WAY more complicated than what I do, so I am unable to understand or integrate into my code.
lock (this) { if (!isGoodPassword) Thread.Sleep(2000); } I would expect that this would allow all correct passwords without stalling, but if one user enters a bad password another successful password from a different user would also be blocked. However, the lock doesn't seem to lock across ASP.NET threads.
I want a example of multithreading .i want to use it in a web form not on console.i am using C#.net .and how to use thread.sleep method for a particular thread.
I have a ASPX page which queries from a database. Once we have the dataset it is bound to a gridview and displayed on the page. All this happens in the Page_Load event.Ofcourse this a simplistic approach. What is the best way to inform the user that data is being retrieved and when we have the data to update the page with the results in the dataset.I want all this to happen within the same ASPX page and do not want to hop around pages to achieve this. I looked at update panels however it wasn't clear to me how this could be done with an update panel without having a control which triggers the update for the update panel. There are no controls on my page whhich initiate the database query, it occurs as the page is loaded
From a web page I start a time consuming job and update it's status on the UI using webmethod.
Job is done in a thread:
ThreadPool.QueueUserWorkItem(new WaitCallback(DoJob), parameters); Job set's it status using static properties, and when web page, using javascript, calls web method it read those properties.
[System.Web.Services.WebMethod] public static ProcessStatus GetProgressStatus() { Jober.Lock.EnterReadLock(); ProcessStatus st = new ProcessStatus(Jober.PercentageCompleted, Jober.TotalNumber); Jober.Lock.ExitReadLock(); return st; }
The UI progress is updated through javascript, the problem is that after thread completes I need to update UI on server side, so javascript won't help me here. What Is the best way to signal when thread is completed?
I've got a page that I'm using as an e-mail template. I'd like to spin off a new thread, take the rendered page, and put it into an e-mail. Is this possible? If so, how? I haven't had luck so far.
I have an application that initially display 4 grid views at page load. This process takes 50-60 seconds and I would like to change the process to display the web page, show message like "Data being loaded, please wait..." and then spin off a thread that fills the various grid view. When this is done I would programatically like to do a post back to show the result. Not sure if this is possible? I tried something like this:
I need to call a function everytime a visitor visits one of my website's page. But I do not want the execution of the function to interfere with the interface between the user and the website i.e. different thread. What is the best way to do that on ASP.Net?
How can I use double buffering in asp.net C#?I want smthng like that : I dont want full page refresh when I click a button in a web page.. I think it can be solved with double buffering. When a button clicked for redirect a content page (button-in master page), current page will not go until the redirected page completely load in the background..
AjaxControlToolkit.ToolKitScriptManager.OnInit() throws thread abort exception for every aspx page. I have an asp.net 2.0 Ajax application, where I have set the following properties of ToolScriptManager on my pages.
I have this configuration on all the aspx pages in my application. When I checked the .NET CLR exception Performance counter I figured out a large number of exceptions, mainly one exception per page load is occuring. On running windbg I was noticed that
AjaxControlToolkit.ToolKitScriptManager.OnInit() has the following code block which is getting executed. The OutputCombinedScriptFile() returns true. But since I am setting my controls on DesignTime still designmode is set to false for toolkitscriptmanager.
if (!DesignMode && (null != Context) && OutputCombinedScriptFile(Context)) { // This was a combined script request that was satisfied; end all processing now Page.Response.End(); }
I am not sure if this is a reported bug or even a bug with ajax, but this is causing havoc in my load test results as I have around 3 hundred thousand HTTP requests to be handled per day out of which 80% are aspx page requests resulting in a large number of threadafbortexceptions, thus affecting the performance.
I have a page that is opened in a popup window from the main page. Once i click insert it pops up a message that says you have successfully added blah blah. Then once you click ok it closes the popup page and goes back to the main page. I want to be able to refresh the main page back to how it was when you first land on the page. Here is the code for my insert button:
MyMasterPage.aspx and content page MyDefault.aspx. MyMasterPage.aspx has one input button [value="Menu-1"]. When user click the button, the button will pass value "Menu-1" into TextBox1Default1 at content page MyDefault.aspx, and then refresh UpdatePanelDefault1 at content page MyDefault.aspx asynchronously.
My problem is the post back is full post back when refreshing UpdatePanelDefault1. I would like asynchronously post back during refreshing UpdatePanelDefault1. copy the full code MyMasterPage.aspx and MyDefault.aspx below, and then paste / overwrite it into your blank aspx page for testing. I am using VS 2008
I am writing a web application which consists of a master page (header / menus) which does not change and content pages. When I do something like click on a button it causes a post back which is correct but this redraws the whole screen and becomes annoying because every post back and the whole screen flickers.
