Web Forms :: Whenever Click On Any Button On Webpage, The Request Goes Through, But Nothing Show Up On The Webpage?
Dec 17, 2010I am working on a financial portal and I am having a problem..I don;t know what to call it so i mentioned it as an 'unknown to me' problem..I have a webpage..whenever I click on any button on my webpage, the request goes through..but nothing show up on the webpage..then If I click on another link and then again come back to previous link,then only I see the results of button_click..
e.g.
I have a currency conversion and investment form..so after filling up the form in following way and if I click on "INVEST" then nothing shows up..
so now if i click on any other link and go back to 'buy currency' link I see the result as 'investment successful'
Subscribe To Rss And Then Save The Content Into A Db?
Aug 5, 2010I want to write a page that shows the content of an rss feed. But I dont want to show only the current rss info but also previous. In other words I want to store every rss feed from the second I will finish building this page. The old and bad method is to refresh every 1 min or so, and compare the rss list to the db list. The rsses that doesnt showen on the db will be inserted.This method looks bad to me and I want some automatic method. What I mean is that when a new feed is posted it will send it to me (as a subscriber) and then it will inserted into the db.
How do I do it? And how do I do it behined the seance (in the global.asax or something?)?
How To 'subscribe' To An Event That Ripples To Client
Aug 30, 2010i can use javascript setInterval() (in combination with jquery ajax) to 'poll' the controller action in order to determine if something 'new' should be renedered onto the page. However, I'm not a huge fan of polling, especially when client browsers can be left unattended and are uneccessarily polling for changes.
Multiply that by the number of potential client machines that could be browsing the app and you get a feel for the scale of the issue with this approach. Now, in truth, this is EXACTLY the approach that I use to refresh certain page fragments on some ('read' - MANY!!) of my existing sites.
However, I'd like to know what the options are for subscribing in 'reverse' to events and having the controller 'know' about the client browser and any events that it is subscribed to and the controller then 'push' out the update to the client on a 'needs must' basis. Is this something that happens outside of the normal desktop events scenario?
Web Forms :: Subscribe To A Web Control Event?
Mar 1, 2010 how to go about retrieving data from another control by subscribing to an even and receiving back results at a later time. I'm trying to see if there is a way to have one web control (Main control), subscribe to an event in another web control (Search control), by maybe only sending in a method within the main web controls class. Once a query event occurs (via Button click) in the search web control, it sends back results to that original function in the Main Web Control (returning a datatable)
I think the goal is to have the search control be unaware of the main control and any specific methods or classes. Only have classes subscribe it it. Kind of like a top down process only. Is there any method that can work to accomplish this? I've looked into delegate methods and EventHandler (EventArgs) methods, but can't clearly see how this could apply.

Using WCF Callback And Web Application To Implement Publish/subscribe Pattern?
Mar 1, 2011I'm trying to use WCF Callback to implement publish/subscribe pattern. I would like to send the message from UserA to UserB or UserA to every clients at the moment. I got an example from here
In my app, I use asp.net as a client to connect wcf service instead and I found a problem when I subscrib to wcf service.
The wcf service does not hold any other clients object. So when I call GetAllClients(_guid), It will return only 1 client which is itself.
Here is the code in asp.net page (i put every control inside updatePanel)
[code]...
Is it possible to implement this publish/subscribe with asp.net and wcf callback? (I already tried on window app and it worked fine)If it is possible, how can I keep all clients that is connecting to WCF Service so I can use those GuId to call callback method.

View 5 RepliesButton To Open A Webpage In A Frame?
Jul 27, 2010My problem is somewhat specific and I do not have enough javascript knowledge to get this rolling.
I have a textbox. Based on what I enter in this textbox I am passing that to a webpage as a parameter and I need that to webpage to open up in a frame.
Here is the code that I currently have. This code is executed on textbox text changed event and is an autopost back. As you will notice this has issues in cases when I click on the submit button but do not leave the textbox... Not sure but it seems that browsing away from the textbox fires the textchanged event.
Is there a java script I could use instead of this postback?

May 19, 2010I'm trying to create a webpage that allows the user to click a button and it will open up a folder on their local hard drive. I've tried doing this in html and javascript, but from what I've read I don't think it is possible (reguardless I want to do it in asp.net so I can learn about it). However I was able to open up a folder when the page loads with asp.net using C#. My problem is that I cannot figure out how to get it to run when the user clicks a button or a link. How can I make the C# CodeBehind run when the user clicks a button?

Vb.net - .net Webpage DefaultDocument Button Click Not Firing?
Oct 20, 2010I have developed an asp.net website in VS2010. The defaultDocument is set to default.aspx in the root directory, as I have dome many times before.For reasons unknown an asp:button in default.aspx is not firing correctly when the url is typed in without the file extension.
For example, if I type the url www.mywebsite.com the default.aspx page will load as expected, however, the button will not fire (it does postback but doesn't fire the server click event).If i type in the url www.mywebsite.com/default.aspx it works as expected.
The problem I'm having only occurs in a live environment (I cannot recreate the error on the localhost).

Onclick Message Handling On A Webpage Button?
Feb 24, 2010I have a button on a webpage that has the following added programmatically to its "Attributes" property.
btnDeleteNode.Attributes.Add("onclick", "if(confirm('delete this node?')){}else{return false}");
This works fine but now I need to check to see if the user has selected a node in a tree before asking if they want to delete it. If a node isn't selected I need to tell the user to select one. My question is, can I do this using the above method (I don't know java script) or should I use a different approach ?
Why Event Bubbling And Why Not Directly Subscribe The Click Event
Jul 2, 2010I was going through an article on event bubbling in asp.net and came to know that although it is possible to subscribe to the click event of a user control's button from the containing page, "doing so would break some of the object oriented rules of encapsulation". A better idea is to publish an event in the user control to allow any interested parties to handle the event.
My question is that exactly how does a direct subscription to the button's click event from a containing page would break the object oriented rules of encapsulation?

Web Forms :: Can Change The Property Of Button To Invisible From Another Webpage
Nov 1, 2010I came to know that we can pass values from one page to another. What I wanted was 'on click of a button on admin.aspx webpage , the button on user.aspx page gets invisible'
After creating the instance and trying to do so, the error occured which said-"due to security the button cannot be accessed on user.aspx from admin.aspx"
Even if all the above what I did was wrong, I request you to suggest me how can I change the property of a button on webform1 from webform2 ( this is the admin.aspx page in which i have logged in) to invisible. And whosoever accesses the webform1 gets the same property (i.e. invisible) untill i click on the button in webform2 that again turns the property of the button in webform1 as visible.
