Of course, every registration needs a primary key like a registration number. I have a textbox that is visible(for now) and I need to have the value inside it(100001) to increment by 1 for each different registrations. How do I achieve this? I need it in C#.

How to increment 10th of a decimals by 1.
The functionality I'm looking for is really simple. I'd like to increment a an integer called
index. Each time I click a button, I post a form to an action method, which increment index and redisplay the view with the new value of the index.
So, I've 2 action methods called Increment (Get and Post versions ):
Increment (GET) action method displays the View, supplying also an initial value of index through the ViewData.
[Code]....
When I click to the button "increment" on the view, I post a form to Increment (POST). The value from the ViewData is sent back to the Controller through an "Hidden field" [Code].... Increment (POST) action method pulls the the value of the index, increments the value, and sends back the new value of index through ViewData when it re-displays the view.[Code]....
Unfortunately, all I can get is ONE increment. in the case above, I get 2. after that, I keep getting 2. If I change the value to 2, I get 3 and nothing else, etc... I suspect that ViewData, once it has gotten a value, keeps it forever.
i am using one text box in New registration page. when ever user clicks on New registration button, The text box of record number should be auto incremented.

View 4 RepliesI got a table PartsMedia where I can insert all the images related to a product. The table has the columns :
PartsMediaID , auto-increment
PartsNo
MediaLink
MediaDescription
CatalogCode
SortCode
I want to insert a complete row with automatic increment and the PartsNo should be the same as the PartsNo from the PartsMaster table.
The medialink should be the PartsNo + '-2.jpg'
The mediadescription is for example 'image2'
The CatalogCode should be 'catalog'
and the sorting code should be '0'
From The partsMaster table I Just need the PartNo So I can add this to the PartMedia Table. The PartNo is the foreign key in the PartMedia table.
The following I got so far but no luck
insert into dbo.PartsMedia (PartNo,MediaLink,MediaDescription,CatalogCode, SortCode)
values (dbo.PartsMaster.PartNo, PartsMaster.PartNo+'-2.jpg','image2', 'catalog','0')
I use SQL Server and when I create a new table I make a specific field an auto increment
primary key. The problem is some people told me making the field an auto increment for the primary key means when deleting any record (they don't care about the auto increment field number) the field increases so at some point - if the type of my field is integer for example - the range of integer will be consumed totally and i will be in trouble.
So they tell me not to use this feature any more.The best solution is making this through the code by getting the max of my primary key then if the value does not exist the max will be 1 other wise max + 1.Any suggestions about this problem? Can I use the auto increment feature?I want also to know the cases which are not preferable to use auto increment ..and the alternatives...note :: this question is general not specific to any DBMS , i wanna to know is this true also for DBMSs like
I have a simple list of data in my database that I call to my page. I have used the asp.net 'reorder list' ajax control to provide a drag and drop way of managing the sort order of my data. It uses a 'position' column in the database to do this.
How do I go about making sure that when inserting data to this table, the new item gets assigned the correct 'position' value? For example if I have 9 items already in my table, I want this newly inserted list item to get assigned a value of 10 in the position column.

In my loop I am trying to remove items from a list that have a certain name. I can't do this with a for-each, so I tried a regular for-loop. It seems the for loop is not working as expected. It always goes over the limit. I had to put an if-then to break out of the loop (very ugly solution). I'm trying to find the correct way to accomplish this.
