How To Clear A Status Message On A Web Form When Starting A Process
Sep 21, 2010
I have a web form used for importing data from a CSV file. It contains a result panel and a result label, which either show a success message or an error message after the import process. Let me say here I know the page should not be doing the import, but this is legacy code and the client expects only small changes.
My problem is that the result message (label) retains it's previous content and visibility during the next import process, because clearing it during Page_Load or at the beginning of the import method only has effect when the import method is complete and thus the postback is complete.
At the moment, the only solution I can see is to move the import code into a separate class (as it should be), call the import method asynchronously, clear the result message, and thne set then result message when the complete or error callback from the import process is called.
i have one independent form where i am checking read only access of an xml file , if the file is read only then i have to display message in the status bar of MDI form. since i am using independent form to valid xml file, status bar of the MDI form is not displaying the error message. now how to display message?
I use it in a webservice, i start it in a new thread and it return exit code 1 (error, i'm trying to do a video convertion with ffmpeg library), i impersonate ASP.NET to use a local account with permissions to read and write files, when i run it in my machine running or debugging it works but know thta the web service is running in IIS doest'n.
First of all, I'm not a pro on IIS configuration topic.With that being said, I got a website written in VB.NET 3.5 Web Forms. I have a small web service, ASMX, running as a part of this website. One page on the website calls the web service with AJAX (jQuery $.ajax function, post). The server is running Windows 2003 and IIS 6.0. The website and the web service are sharing the same Application Pool.
I need to essentially make a command line tool available via a web interface. This tool would need to be run ON the web server, not the client machine. e.g.: someCommand.exe -aSwitch param1 param2 The tool will be in a windows integrated auth web app on an intranet. I have not had to do anything like this before, so I want to find out how others handle this, what is the recommended best practice? a quick google first showed someone using system.diagnostic.process... so to start playing I did something like this, just to see if it works, it does:
[Code]....
I won't be running cmd.exe, that's just to test with. The actual command line tool I will be using is not on my dev machince right now. . is using system.diagnostics.process, processStartInfo, and start method acceptable? my goals:
1. use recommended best practices, especially with regard to security 2. I'd like to start the command, and use ajax to display the commands output as it runs, and of course I need to know if it was successfull or not.
Note:- i don't want to use updateprogress etc. control of ajax
on button click, long task(e.g thread) runs in my webpage for about 4-5 minutes.I want to show status to user either by a processing image through javascript(image must be shown in a certain part of page other part of page will remain intact) or an exact status of process if possible. i have tried a lot but all in vein.
I have a process that retrieves html from a remote site and parses it. I pass several URL's into the method, so I would like to ajaxify the process and give a screen notification each time a URL completes parsing. For example, this is what I am trying to do:
List<string> urls = ...//load up with arbitary # of urls foreach (var url in urls) { string html = GetContent(url); //DO SOMETHING //COMPLETED.. SEND NOTIFICATION TO SCREEN (HOW DO I DO THIS) } public static string GetContent(string url) { HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); request.Method = "GET" using (var stream = request.GetResponse().GetResponseStream()) { using (var reader = new StreamReader(stream, Encoding.UTF8)) { return reader.ReadToEnd(); } } }
In each iteration in the loop, I want to show the URL was completed and moving on to the next one. How can I accomplish this?
In fact, I DO NOT want to ask a question but to share one solution to this. One cause of this problem is you did not register your sql express on iis.I installed .net 3.5 sp1, then ran aspnet_iis -i, then installed sql express 2005 advanced. Yes, here came the notorious alert. So, I ran aspnet_regiis again and everything is OK.Run aspnet_regiis before you have installed sql express.
I have a form that works just fine, problem is that if user leave form open for more than 20 30 min and then click a button on that form the browsers status line shows "Error in page", user then must refresh the page in order for the page function.
I am trying to work out the best way of dealing with a mailinglist class I have written. I got a simple form on the page where people can add their email address. Depending on which page they add their email address they join a differnet mailinglist. So from the form I have 2 values passed to the DAL {mailinglistID} and {email} - Various checks are done in the DAL, such as checking if email exists, checking if email exists in that mailing list etc etc.
I would like to be able to present the status codes on the page, so in the DAL I return a number value and from the BLL return a string depending on the number value. DAL returns 1, means email exists in mailing list, BLL see's the 1 and returns "email exists" to the page.
I have no idea if this is the right way of doing it or not - the (problem or question) is that in the content page I am checking the if the returned string is "" or has a value, and presenting the message in a visable div.
Is this the best way to do this, or should the status value be converted to a message on the code behind of the content page.
(of course I could have got this all wrong, and need to start again.
I am having problem in returning a status message (success or failure) from my sql server sp here is the code: [Code]....
"Status" is an output parameter which is supposedly getting the message from sp and we are not able to get its value since "dbCommand1.Parameters["@status"].Value" returns NULL everytime! SP is available on request.
I am using VSS 2005 & webforms with AJAX Control Toolkit. I am using Update panels for saving different parts of my form. Problem being I update the user with the status setting either a label or literal value.
This value is visible on the form untill the page is refreshed. Is there any way to display a message and fade it away after some seconds ? Would be a life saver for me =)
I am using VSS 2005 but I don't think a simple fade would require much intellisense with JQuery ?
The effect I want is that a status message band "slides" open after an action.I'm trying to implement this with an updatepanel in the master and setting it's control values from the web page, who's content is in another UpdatePanel in the master. in pseudo-markup:
[Code]....
I figure I could use an ajax accordion or something for the expanding effect...But I can't figure out the event timing and how to update the status message. If I update it within an exception in the child page, the message doesn't get displayed.How can I pass a status message to the master and have it displayed in the manner I explained?
i am trying to figure out how to display message box after it done executing the server side code here is the code which works from the client side but still looking for a way to make it work from code-behind.aspx
<div id="status"></div>
script:
$("#status").fadeTo(500, 1, function() { $(this).html("You are now registered!").fadeTo(7000, 0); })
I am running huge time taking background process using a thread. Now Is there any way to show a javascript message whenever the background process completes.
I am using a user control to run the background process. How will I fire the javascript whenever the background process is complete which is unknown.
I have code to copy some files. and then, how I can to show the message of process copy. I think in command prompt (cmd) we can do that with piping to file(txt file). how I can do that.
Is there a simple way to clear the value of server controls on postback? I have tried ViewState.clear() and it doesn't do anything. The page I am working on inherits from a Masterpage that has viewstate enabled.
HTML has an input button type to reset all fields in a form to their initial state in one step: <input type="reset" ... />.
Is there a similar simple way to reset all form fields of an aspx page from code-behind? Or is it necessary to reset all controls one by one with TextBox1.Text=string.Empty, TextBox2.Text=string.Empty, etc. ?
Update:
Context is a simple Contact/"Send us a message" page with 8 asp:TextBoxes on the page (where the user enters the name, address, phone, email, message, etc.). Then he clicks on submit, the Onclick message handler in code-behind sends an email to some administrator, and all the form fields the user filled in should be emptied and he gets a notification in a label ("Message sent blabla..."). I want to have the form fields cleared to avoid that the user clicks again on submit and the same message is sent a second time.
For an MVC 2 app that relies on many partial views and almost exclusively uses Ajax for POSTs/GETs, what would be the best way to implement the setting, passing, retrieval and display (using a JavaScript modal) of these messages?
My forms all POST (by way of jQuery $.ajax) to actions that return partial views (html) that are used to update a in the "success:" part of the $.ajax function.
I was hoping for some sort of mechanism in the master view that could "listen" for any messages that any of these partial views might be "delivering"--through their ViewData, for instance.
I have a contact form inside of an update panel so I don't get the page flicker. Once the form passes validation and the email sends, how do I automatically clear the text boxes?
I have a form containing 7 fields and I want that when i press submit button all the fields are cleared how can i do this? In my form when i click submit fields not clear until I refresh.
I have one issue on my localhost running website that is when i submit data from asp.net form . it don't clear the data permanentaly from the page history.like , i submit one record and after this one i double click on the textfields the previous values are shown ?
