Web Forms :: Prevent Duplicate Values In Listboxes
Feb 17, 2011
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
[Code]....

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?

I 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?

In 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 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?

we 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.

I have a master table relationship, i.e. depending on what is selected in the dropdown list the grid show the relevant data.In the database there are several identical entries for the Position field, for instance there are four marketing managers that have different name. How can i group the identical Position name in the dropdown and when selected the grid should display all marketing managers. Here is the code:
<asp:DropDownList ID="DropDownList1" runat="server" DataSourceID="sqlDdl"
DataTextField="ID" DataValueField="Postion">
</asp:DropDownList>
<asp:GridView ID="grid" runat="server" AutoGenerateColumns="False"
DataKeyNames="ID" DataSourceID="sqlCon" EnableModelValidation="True">

I have a gridview containing serial-numbers.
I would like to format the background each data-row that contains a duplicate serial-number value.
I'm planning to do this using a DataBound event handler.
So, in English:
Set background colour of THIS_ROW to red where the Serial_Number of THIS_ROW is the same as the Serial_Number of ANY_OTHER_ROW.
All rows with duplicate serial-numbers would be red.
I'm not sure how to write the code for this event.
The gridview is bound to a SQL datasource. Getting the dupes in SQL is easy:
SELECT Serial
FROM Table
GROUP BY Serial
HAVING (COUNT(Serial) > 1)

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?

Im using Microsoft Expression Web 3 and am in the process of making a page for my Cab Company that basically calculates the price from an area in London (In listbox A) and an airport (In listbox B) along with the type of car used (Saloon, Estate, MPV) in a checkbox list.
If I were to set a value for each and every item in Listboxes A, B and Cars, is there some sort of autosum code I can use which calculates the price. The feature is only going to be a pricequote system for now untill we get some sort of booking system up and running so it is preferred that all calculations are done & displayed on the same page.

suppose I am having sample table like below.
I need to remove duplicate orderid's and i need all column names also while doing query.
note that rows are not in the order. Order will be like this only.
I am able to get the records which are duplicated but not able to delete further.
In this case how to delete?
My consideration is that only distinct orderid's should be there in the table. Not bothering about the which orderid row is being deleted.
name orderid destination
a 1 aaa
d 2 ddd
b 1 bbb
f 3 fff
e 2 eee
g 4 ggg
h 3 hhh
c 1 ccc

Well the dropdownlist has an existing items. I just want the selected gridview record to be displayed in the dropdownlist. The dropdownlist has several DataTextField in string and consist of DataValueField in numeric. The gridview passes a string text to the box which has an equal or same item inside the dropdownlist. Whenever i passed a record from a gridview to be viewed in the dropdownlist it just duplicates the same item. Q: How can i simply pass a text inside the dropdown and just simply display it without adding on the list.
sample item on the dropdown:
--Select--
Account
Savings
after selecting on the gridview and display inside the dropdown:
Account
Account
Savings
(you see the '--Select--' was erase and replace with the selected record)
