The subject says it all really. I have a DetailsView which inserts records into a SQL database. It works fine.
When I refresh the page (F5 for instance), I get a dialogue saying such action will resend the data. If I click OK here, the daa does indeed get sent again resilting in duplicate records in my database.
How can I stop data being resent if the page is refreshed?
I m working on ASP.Net database related project. I have one form including one Button, On ButtonClick I m inserting data into database.

I dont want this, so suggest me what is the problem.
I am using an ObjectDataSource in my FormView for INSERT.
Data inserts correctly to my backend SQL table, however as i am posting back a success/fail message to the same page, i have noticed that after a successful INSERT if it hit the Refresh button the INSERT is doubled up.
How can i stop a user pressing the Refresh button and doubling the INSERT?
Is there a setting somewhere or can i stop this programmatically within my ObjectDataSource_Inserting method perhaps?
I have a webform which users fill in and all fields are submitted to table. How do I check that the record doesn't already exist in the table before the data is submitted? And if the data does exist I'd like to display error message label.
View 10 RepliesI have a page which consists of a grid and add new button. When the user clicks add new button he gets several fields to be entered. So, when he clicks submit I usually write a query which checks if there is an entry already in the database. In this case, I succeeded. However, my task is to also show the records identical and let the user decide to proceed or not.SO, I am not sure of how to proceed with this one. So, can anyone just help me in giving an idea on how to proceed with this one?
View 1 RepliesWe have developed the Application using Visual Studio 2008, After publish we got the issue like After Submitting the Form the user can able to Move Backward and do the Refresh. This will again triggers the Submit Post Back and the Duplicate Record Created As Well.
This is happening for all the Web Forms. How to Avoid this ? I need a Generic Solution where i can implement that logic in Base Page then the rest of the Pages this functionality will be covered by default.
Moreover, Before Refresh We should also intimate user "Do you Want to Post the Same Data Again ?", if the user clicks Yes then it can allow the same record can be posted again.
How to do this ?? But i cannot disable the Browser Features like back, forward and Others. I have found many solutions in various web sites but it is also happening for the Validation Part Also...
I am using an application called "SAFE" from ASP. This application using for enter the aircraft and personal injury accident.
Once we enter all the details and click the submit button. The next page will open and show the message details like report number.
Report Number will generate depend on sequence.
If you press F5 or refresh in the same page, get the pop up message "Retry" or "Cancel".
If click the retry button, the same input details is saving and generating the next sequence report number.
I need to write a sql script which will scan for records in a table (Table1) and thencopy the records found into a second table (Table2). Table2 has the same table structureas Table1Table 1 has a primary Key for the first column named CustIdI thought this would involve A simple sql statement like:
INSERT INTO Table2
FROM Table1
SELECT *
However I just realized that if A record already exists in Table2 and I try to inserta duplicate record into Table2, how should this be handled?Should I instead use an Update statement without a where clause?
I'm getting duplicated rows of data showing up in my GridViews. I have two GridViews, each showing different data. I'm using SQL queries to retrieve the data from 2 database tables (1 query pulls from one table and the other query pulls from a second table, but references the first table in the WHERE clause). The GridViews were not duplicating data until after I added the Data Binding code to each GridView event handler and the button click event handler (outside of the GridView). I double checked my SQL queries by running them in TOAD and did not get any duplicated rows. So the issue is not with the SQL queries. It appears to be the GridViews causing it, or the Data Binding, or combination of those two, but I'm not sure what it is.Has anyone heard of or seen this? If needed, I can post my VB code and GridView code.
View 7 RepliesI 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.
Is there a way to only refresh the content page?

View 5 RepliesI have a formview and inside it there are two textboxes taking integer as input.I put a condition that if both textboxes are empty then user should be notified that "Please put value in any one of the textbox".It is working very fine.From database side DBA checked that if user input any integer value in any one of the two textboxes and if it is already found in database then there is no insertion.The problem is that everything is working fine and i checked in the database that the record is also not inerting due to duplicate check but user is getting message that "Record inserted successfully."How to stop this message and how to notify user that you have entered duplicate value and transaction should also not been done. Means all inputs should be there rather than clearing textboxes that could be done when "Record Inserted."

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.

I'm doing an ajax work where web service will return data and on client side and I am creating html table with data.I am using var (to hold string of generated html code), do string concatenations to generate table, tr and td tags and put data in it. Then I put this html table with data into a div using innerHTML. I am applying inline css in this dynamic html code.
The issue I am facing is the web service will return a huge amount of data. What I tested is even on local machine it took about 10-12 minutes to process (concatenating, creating tags putting data in table, applying css) 10000 rows. Stored procedure just take 3-4 seconds in returning data. how this in-browser processing time can be reduced ? I am doing it for speed in some wrong way ? Or is there some technique for it or some method faster than innerHTML and string concatenations ?
I have a gridview with delete buttons for each record (I've used AccessDataSource). I have loaded the data in and have many duplicate records.
I just want to use the delete button delete each duplicate record while remains many duplicate records. For example:
I used the following query to load in duplicate records:
SELECT * FROM TableA WHERE ([ControlA] IN (SELECT [ControlA] FROM TableA GROUP BY [ControlA] HAVING (COUNT [ControlA]) > 1)))
ID ControlA PIN# FaceValue Date
delete 76637 128232 1234 5 6/4/2006
delete 72722 128232 1234 5 6/4/2006
delete 76638 234567 2345 10 7/3/2006
delete 72723 234567 2345 10 7/3/2006
What is the query to delete single duplicate record instead of deleting all duplicate records?
