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?
i have a dropdownlist (asp.net control) and a listbox control and a Add button when the user select the item from dropdownlist and click on add button to add to the listbox.
how can i prevent the user from adding duplciate items and alert saying its already in the listbox?
UPDATE:
in my particular scenario, i have a dropdwonlist and adding the item to listbox both are asp.net controls and i am adding the items from code-behind and your solution is pure on client side, is there a way i can read the listbox and compare and alert the message?
Simple one here... is there a clean way of preventing a user from double-clicking a button in a web form and thus causing duplicate events to fire?
If I had a comment form for example and the user types in "this is my comment" and clicks submit, the comment is shown below... however if they double-click, triple-click or just go nuts on the keyboard they can cause multiple versions to be posted.
Client-side I could quite easily disable the button onclick - but I prefer server-side solutions to things like this
Is there a postback timeout per viewstate that can be set for example?
I have 2 listboxes, when i add a item retrieved from database to Listbox1, i need to select the item and bring it to listbox2. But i do not want to have same records added again. In my case, i cannot use the codes below
[Code]....
because the text displayed on listbox1 and after transferring to listbox2 are different. So i come out with a logic which is "if listbox2 does not contain the item value in listbox1 then populate listbox2". So i tried the codes below, but it is not working as there are errors

I am learning asp.net web development. I have create a table with the column "username". But i don't know how to prevent the Duplicate "username".
View 5 Replieswe have bridged our log4net with Jira using SMTP.
Now we are worried that since the site is public what could happen to the Jira server if we get alot of issues in the production environment.
We have already filtered on Critical and Fatal, but we want to see either some acumulator service on log4net or a plain filter which identifies repeating issues and prevents them from being sent via Email. Preferably without having to change the error reporting code, so a config solution would be best.
Example: url is [URL]
I click an asp:Button which cause a postback, but now the url comes up:
[URL]
There is nothing special in the button, just id and runat.
This only happens when I start with the "/88" in the starting url?
Why, and how can I prevent the duplication. After the postback I want the url to be the same as when started.
Is it possible to setup the CreateUserWizard to check for a duplicate entry in the aspnet_profile table (for a custom field) before the new user is created? For example, if I added a phone number field and wanted to make sure nobody else could create an account using that same phone number if a user already has an account with that phone number in the aspnet_Profile table's PropertyValuesString row?
View 10 RepliesI have a database table that stores a list of friends. The table can store many friends and there can be duplicates, for example - John is James' and davids' friend. John will be in the table twice but will be linked to the others via another data-member. What i dont want is james to be down as johns friend twice in the table. I'm doing a small social network and this is possible by james accepting john as his friend twice. Is there anything to check if there are 2 columns identical?
View 3 RepliesIn my website their is a module in which I m retrieving the data from the student master table..
In my gridview their are 5 columns (Student Id,Student name,Roll no,and a checkbox column,Date Textbox column which is empty) in which the data is retrieved from student master table....
I m adding the date in the textbox which is out of the gridview and when i check the checkbox for each student the data is stored in another table in database with a status as present for the checked students and absent for the unchecked students...
What i want is dat when i check the student and i select the date for the student and the data is entered in new table after all this i wld not be allowed to make the attendance for the same student for the same date bt i wld be allowed to mark attendance for the same student for another date..
for example i check the checkbox for the student "Rohit" and entered the date 1/1/13 and rohit is stored with status present in the another table for date 1/1/13 and now he shld be disabled so dat i wld not be able to mark his attendance for the date 1/1/13 and prevent the duplication...Bt after dat i would be allowed to mark "Rohit's" attendance for the date 2/1/13...
means he should be disabled for the single date...

I Have one gridview which i show in admin panel and need to allow edit and delete the row.now my problem is when click on edit i need to check that duplicate record not allow to enter and my password is in encrypted formate and i need to show decrypted form in gridview so if admin want to edit password then he can edit it
And at a time of edit gridview can i give option of dropdow to selection instead of text box?
I 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 am working on a project in .NET (C#), connected with a database. And I am entering values in database through 'text-box' control, for a part of the project. What I want is to check if the user entering value already exsists in the database and if so, shows error during that time only.
I have searched for any familiar post here, that could solve my query, but didn't get any.
my EXACT objective(if not cleared earlier):-
when the user enter the value in
textbox, automatically an event to
check any duplicate records in
database should occur. And if found,
displays an error message
On inserting record, I want to check that for example if a user enters a telephone number for any record is already in the database then it should validate that the number already exists in table and you cannot enter a duplicate value.
Then if user will provide some other telephone number then he allows to insert record.
For insertion of record I used ObjectdataSource.
User will enter telephone number in a simple textbox.
I may want to inform that I am working in asp.net2.0 and also not allowed to use any third party control or ajaxtoolkit.
Students can subscribe for any project via a webform. Table 'project ' contains all the proposed project and table 'student' contain the name of the student and the project-id.Now, suppose there is a limit of 4 students for project 'A' and there are already 3 subscribed students for that project. One more student can choose that project. The code-behind checks whether the limit is not reached (by counting the amount students for that project in table 'student') before inserting that student in the table 'student'.
My problem is that when two students fills the webform for the same project and click on the 'save-button' exactly at the same time, the code has no time to check the limit and both students are inserted into table 'student'. Is there a way to lock the table or something in order to preventing this?

For example, I have a table with a schema

Thus, rejecting all the duplicate times within 01 Minute period for that specific employee.
