Forms Data Controls :: Prevent Double Post Submit Where Page Is Refreshed?
Jan 25, 2011
Some say it is not a bug it is default in asp.net. but for me it is a bug in logic. When you say refresh it should be reload the component that you are refreshing. But in asp.net i notice that they recalling all activity and viewstate like event and data that are triggered in the previous postback. My opinion it is a redo not refresh. this is only my observation on the issue dont hate me on this microsoft fan.
I have a special requirement with regards to popping up a MsgBox in ASP.Net. There seems to be various solutions across the Internet using the Javascript confirm box, and passes the response to a hidden control, from which VB.Net can the read and further respond ...but the Javascript code is initialted by a button on the ASP.Net Form. I want to be able to pop-up a MsgBox in the middle of my VB code-behind using the Javascript trick, which passes the result to the hidden control, which can then be read by VB.Net .... the problem is that the page has not refreshed and the hidden control still contains the value from the previous Submit .... I'll attach my code. If anyone can come up with a solution, will you have achieved the impossible!
I have created a page with a gridview in asp.net that displays the records of a database table and allows users to delete checked records by clicking on a delete button. After I delete a record and I try to refresh the page from the browser (I am using mozilla)I get the follow message:
"To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier."
and if I click resend another record is deleted automatically. Even though I am reloading the gridview after the deletion the application executes again the onclick event of the delete button is executed and the gridview things that there is a checkedbox selected so the code executes my delete function again.
Is there any way to get rid of these behavior. I have been trying quit a few things but nothing works for me.
I use submit button to post to database which successfully show in gridview but i also want to use thesame button to show a post back as confirmatory page that you have successfully submited a post please, how can i go about the code to perform these function, i use property section of the submit button to do a post back to confirmatory page , the page show but message fail to show in grid view. a simple example of what i was trying to do is this, when u write a post in this forum now , u press a button to submit a post and a confrirmatory message is send to u. what is actually performing the two functions.
I need to send some parameters to an external website using the <asp:HiddenField /> controls and also at the same time, submit data to a sql server database. The part for submitting the data to the database is working, but I need to try to get the parameters from the hiddenfields to also be passed through. I thought all I had to do is create the hidden fields and in the code behind, set the values from the textboxes that the user would fill out.
My source code is below:
[code]...
What am I missing? The hidden fields are losing their value before posting to the external website. I've looked everywhere to see why this won't work.
I am running into a strange problem I don't fully understand. The main symptom is that when I double click a link (that points to a controller action) in my MVC application, my database server connection gets blown, and I get the error :
Execution of the command requires an open and available connection. The connection's current state is broken.
If I step through starting at a breakpoint at the top of the controller action, it will step down a couple lines and then jump back up to the breakpoint. Somehow the first request isn't executing fully before the second one gets there, and somehow my database connection breaks when it gets to any query. Every time this happens, I have to restart the application server.
It was happening intermittently at first, but the double clicking of links seems to reproduce it everytime. Does this happen to anyone else? What am I missing here?
Update :
A.) I incorrectly tagged this as Linq-to-sql when we are actually using Linq-to-entities. B.) The connection object is defined as a member variable of the controller :
[Code]....
I noticed in some of the asp.net tutorials they declare the variable in the same spot but have a separate constructor for the controller where the db object is initialized. Does this make any difference?
C.) The problem is not only with the double-clicking as described above. The connection breaks at other seemingly random times; I cannot seem to reproduce the error consistently (even double-clicking does not always break it). Restarting the web site usually fixes it, although sometimes I have to restart the host machine. After its back up, repeating the same sequence of actions usually does not reproduce the same error!
Maybe there's something I don't understand about setting up my linq-to-entities classes or the nature of the database connection. Does anyone have any thoughts? I really don't even know how to investigate this one!
I have a LinkButton inside an UpdatePanel that I do not want the client to click more than once before the UpdatePanel refreshes its contents. Right now the link button initiates a partial postback for every client side click until the update panel has time to refresh. This particular link fires off a very expensive process which I'd rather not have run unnecessarily. Is there a .NET standard way of doing this? Whats a good solution for this?
I want to submit the form with post method, but before that i want to do some processing in CS file, after the processing is done then the form will be submitted in post manner like <form method="post">

Then I using a UpdatePanel to perevent the refresh. But in this way the file is not uploaded and FileUploaded.HasFile property return false. What can I do?
I am running the code below to read a sql table and populate the values into a list. This works on the first run through, but after the data has been processed, and the process then re runs, if the sql table has been modified externally, the read of the records does not change. I imagine it is being cached somwhere but as I re dim the dData variable, shouldn't it all be dropped and run afresh?
