i have treeview filled from database. I want specific information after selection of treeview node, I have used sql query on
selectedindex changing event as well as used Datarow rowfilter property to filter specific data from datatable(filled on page load event once), but the processing is very slow. Is this is technical issue. I used ajax 3.5. I have read articles regarding Update Panel that processing is slow inside it.
We are in the process of building a huge site. We are contemplating on whether to do the processing of HTML at server side (ASP .Net) or at the client side. For example we have HTML files which acts like templates for the generation of tabs. Is it better for the server side to get hold of content section (div) of HTML load the appropriate values and send the updated HTML to the browser or is it better that a chunk of data is passed onto client and make Javascript do the work?

View 10 Replieson the following.I am having a requirement for three GridViews (GV1, GV2 and GV3) to be nested within each other , GV3 being the inner most and GV1 being the outermost. The 3 GridViews are populated from non-SQL datasourse. Each Gridview has only column.A dropdown listbox is provided on the page and the value selected (say ID1) from the dropdown listbox is used as a filter for the query used to get the data from the database to populate GV1. The ID for each row displayed in GV1 will be used as a filter for the query used to poplulate GV2. ID2 for the row displayed in GV2 is used in the query used to populate GV3. GV3 will display rows of llnk buttons. When the user clicks on a link button in GV3, I want to be able to retrieve all the three IDs (ID1, ID2, and ID3) for further processing. The rows displayed in GV1 and GV2 will have different background colors.
View 2 RepliesI have a 'Generate' button on form that does some file processing. It creates files, zips it etc etc. I would like to add some wait time (3-5 seconds) in the logic so as to complete the file processing logic. What happens right now is visitor clicks the button to generate those files and clicks another button to download. When they try download button many times the files are not created as in processing. So it fails to download. The only way I can ensure it does processing for longer period to allow completion.

My Code Behind
[Code]....
This is what I am doing now:
Step 1 : The partner does an HTTP post on my server webpage.
Step 2 : My webpage gets the posted data, and does processing and generates a response number. I have a literal in this webpage, and I assign the response to this literal.
Step 3: The client parses and gets the response code from my webpage.
My question, How can I know that the client got my response code? (ie there is no time out issue)
I have a web page that loads in user-defined text from a database field into a label. This text may or may not contain HTML links (standard <a href> tags). I need a way to enumerate through the links and enable/disable certain links based on whether or not the person viewing the page is logged in or not (via a session variable).The html tags include a runat=server attribute and the text is standard formatted HTML. Since the text is being loaded into a label straight from the database, the links aren't loaded into the controls collection for the form - so, I'm not able to reference the links that way.
View 1 RepliesI was wondering if there was anyway to populate the page with asp.net code like "<asp:Repeater ID="rptProducts" runat="server">MORE_CODE</asp:Repeater>" and then have the server use that code on the page. I'm not sure if i'm making sense. Like writing the asp.net front end code to the page dynamically before the .net engine generates the output html.

View 7 Repliesi am into web development using asp.net but reg some concepts i need to be clear i am not much awate abt the netwroking & the routers , SMTP server etc i am aware abt public domain /IP which is accesiable all over like yahoo.com so when we attach a file, or place images or upload images or give hyperlink the files get stored on this publicly accesiabel space & hence visible frm anywhere
same is the case for intranet web applications/sites. its accessibale in the LAN setup as here too we have a server where we can store images files etc
so if i need to send emails with hyperlinks, attachemnents images etc & which shld be accessiable frm anywhere i need to have a public doamin & space & al this gets stored in that public space (server)
i think my this concept abt the intranet & internet is clear . if anythinh left out wuld like to knw
but i have come across a prblm in which i need to do communication between the intranet & internet
i have a server in the intranet . when i attach or link any files/images frm my emailing module frm my intranet server it shld be viewable even out side the LAN setup. for doing the same wht SMTP setting needs to be done, or shld i set up a mailing server. i dont have a public domain . without a public domain/space how can i achieve it whts port_forwarding & can my soulution be achieved using it
reg the same wht can be the best possible way that can be achieved
My scenario is that when a user clicks a link to download a file, a large file will be downloaded. But many files are zipped and to become a requested large file, files are needed to be unzipped at the server side and download it. Meanwhile unzipping the files, I wanna show to the user how many percent of files have been unzipped.
So, I save the current condition of % into the session () and it has been updated accordingly and in the other page session is called using the iframe to be seem as they are in the same page. But the problem is that,
while updating the iframe with update pannel and timmer tick event doent work and only when unzipping process has done, it works.

I want to show a processing image on every page load how to do that...Not only in button click it should happen in all page load. It should start when page load starts and ends when page load completed.

Situation:
1) Click on 'Check' button and the button will disable
2) Run a processing code(for checking) and once it is done, navigate to a new page(NewPage2).
Here are 2 code situations (1):
[Code]....
and if I do this way (2),:
[Code]....
it will navigate to NewPage2.aspx, but during the execution of the processing code, ButtonCheck control will not be disabled as the Click Event has not finished, and I want it to disable during the checking process. If the 1st option is executed, it will throw to me "Response is not available in this context."? HttpContext is null for (1). In my opinion, I think that the navigation does not recognise the response object as it is in a thread and has exited out of the buttoncheck event. But I'm still not sure why.
how to disable the button and run processing code during the click event and be able to navigate to a new page?
On my current project I have to accept 2 Excel spreadsheets that will be uploaded by clients, process them and create a download package based on this information. This process includes extracting data from the sheets, updating our databases and building several PDF files for the download package. This takes between 15 seconds to 2 minutes to complete, depending on the complexity of the request. Naturally, I want to show some kind of processing indicator rather than just leaving the user hanging while the page loads.
Here's the problem: How to show this processing indicator.
I have to do a full postback to upload the files so this eliminates several nice AJAX indicator methods (sponsoring users rejected the AJAX toolkit async file upload, saying it was confusing to them). If I process on any of the page events during the postback, the page doesn't load until the lengthy process is completed so the browser/site looks 'hung'.
Basically, I need some ideas on how to display a 'building your download' graphic while the lengthy process is working that will also work with a full postback.
I am able to route my urls to an existing page. Here is how our scenario is currently working:
On Default.aspx, we have several links that link to pdf files on the server. The filenames of these files change dynamically which is why we need the url routing. When the user clicks on of the urls, the link is routed to the getFile.aspx page that has logic in it to determine which file to open.
Is there a way to have the getFile.aspx page to open in the same window as the default.aspx page?
Otherwise, I need for the getFile.aspx page to close after the intended processing is complete, and I've not been able to close it without getting the close window dialog box. I figure if it opens in the same browser window, I can redirect back to the default.aspx page when processing is finished.
I am using ASP.NET 2.0 with C#(No AJAX) in my project. In a particular web page, when the a button is clicked, some server intensive C# code runs before the same page is displayed again with the results. While code execution happens on the server in response to Button_Click event, a blank white page is shown to user on his browser in between post backs. How do i show a message in this case, that the processing is still going on and ask the user to wait? I have used javascript to show a message on page unload. But this message is also erased when the page is posted back to the server and the user sees a blank white page on his browser. How do i avoid this white page? Is there a way to show a message in the blank white page? How do i show a processing Message while the page is loading upon on Post Backs to the same Page.
