I have a gridview with a column holding the price of a transaction. I need another column added which will keep a running total, something like:
Trans ID Price Total
1 £1 £1
£4 £5
3 £3 £8
I haven't generated this using datasets or any back end code, I only call the results using the DataGrid controls. Is there a simple way to add this new column?

I have a SQL Server 2005 database which is queried by a web service which is called by an aspx page.
I inherited a messy and inefficient project, and I was working on cleaning up a GridView by making it dynamic and by having consistent field names in the database when I started getting an error of - Sys.WebForms.PageRequestManagerServerErrorException: Invalid column name: 'ASSIGNED_TO'
Assigned_to does not exist in the database, in the web service, or in the website solutions in any place. It was the name of one of the fields in one table, which I changed to USERID so that either of two datasets would fit into a Gridview (all other fields were the same). I then replaced all references of ASSIGNED_TO with USERID, which is when the issues began. The first of the two queries below causes the exception to be thrown, but the second one does not. I have tested both with the WCF Client and with a query within SQL Server to verify that they do work, so the issue has to be on the website side.
sSQL = "select distinct B.BADGE_NBR, a.REGId,B.CYC_RTE, b.USERID, a.MTRREAD,A.NEWMTRNUM, a.COMPTIME, B.FA_TYPE, CASE WHEN A.MTRCOMMENTS <> 'Null' THEN '*' END as Comment,a.MTRLAT,a.MTRLONG,a.WOFAID, b.ADDRESS, a.MTRREADFLAG, b.ROUT_SEQ from MobileDataReturn a,WORKORDERDIPATCHFILL b Where a.RegId = b.REGID and a.WOFAID = b.FA_ID and B.CYC_RTE " & route & "' and b.USERID " & worker & "' and B.BADGE_NBR " & badge & "' and a.MTRREADFLAG " & readflag & "' and b.FA_TYPE " & fatype & "' Order by a.COMPTIME desc"
sSQL = "select distinct BADGE_NBR, REGId,CYC_RTE, USERID,MTRREAD,NEWMTRNUM, COMPTIME, FA_TYPE, CASE WHEN MTRCOMMENTS <> 'Null' THEN '*' END as Comment,MTRLAT,MTRLONG,WOFAID, ADDRESS, MTRREADFLAG from MobileDataReturnArchive Where CYC_RTE " & route & "'and USERID " & worker & "'and BADGE_NBR " & badge & "' and MTRREADFLAG " & readflag & "'and FA_TYPE " & fatype & "' Order by COMPTIME desc"

Heres the situation: I need update a column from my table (T1) from two other columns in a different table (T2).
My constraints are:
That I have to match the first 4 letters of a column in T2 to one column in T1 I have to identify that the first letter in a column in T1 corresponds to one letter in the middle of a string in a column in T2 For instance:
My Table (T1):
Order Type Combined
Place
0090 0001 YYXX 1YY
0091 1001 YYXX YYY
0092 1002 XXXX 2XX
Table 2 (T2):
Order Value
00900001YY XX
00911001YY XX
00921002XX XX
The Combined column in T1 is what i'm trying to complete. The T1.Place column contains the first character that I want to check for.
If it's a "1" then I want to make sure the 5th letter in T2.Order is a "0" If its a "Y" then I want to look for a "1001" If its a "2" then I want to make sure the 8th letter is a "2" in T2.Order
If all that matches then I was the last two letters in T2.Order + T2.Value to be combined and put into the appropiate spot in T1.Combined
Here's what I have:
[Code]....
I know it's a little complex, but i'm really stuck on it and any help would be greatly appreciated.

I'm trying to figure out how add extra logic to this derived column expression:
LEN(TRIM(pup_date)) == 0 ? NULL(DT_DATE) : ((DT_DATE)(SUBSTRING(pup_date,5,2) + "-" + SUBSTRING(pup_date,7,2) + "-" + SUBSTRING(pup_date,1,4)))
If there's a 0 in the field the code inserts a null. Otherwise it inserts a date. How can I change this to insert a NULL if a question mark "?" appears in the column?
This is what I tied using the OR operator but it's not working:
LEN(TRIM(pup_date)) == 0 || LEN(TRIM(pup_date)) == "?" ? NULL(DT_DATE) : ((DT_DATE)(SUBSTRING(pup_date,5,2) + "-" + SUBSTRING(pup_date,7,2) + "-" + SUBSTRING(pup_date,1,4)))

I run a web site with VB.Net and Sql Server, at a web host (so I use one instance of their Sql Server db). I now get this nasty message when trying to access the web site: Column 'kryptotext' does not belong to table tabellen. I have seen this before (but with other columns mentioned), and when I spoke to the tech guys they said that the server gives up after five (or so) invalid requests. The old problems I had were due to the fact that I had used Application variables - at least the problems appeared when I added the variable and diappeared when I deleted them.
This time, I have done very little. I ran a new check when some items of a gridview were databound, and if a condition was ok, then a mail should be sent and an update take place in the db. For now, this will not be true, so the new code doesn't fire, and I have now reverted to the old code anyway. I got htis message this morning, and then it has worked the entire day without me changing the code at all, and now it stopped working again, so to me it seems as if it's either not my code's fault, or I somehow flood the db server with requests (but the web site is new so there are really no users yet). One more thing I have added: I imported the Net.Mail namespace to the baseclass I'm using for the aspx pages, but I can't believe that has anything to do with this.
I asked the tech guys again, and the server has been working the whole day. Here's the web site: [URL] I am able to connect to the admin part of the web site, so it's just the public web site itself that doesn't run. What should I do? Edit: Now, 30 minutes later, it works again. I haven't done anything, in fact I had dinner now.

I am looking to sort a column on my gridview by simply clicking on the column rather than clicking on the column header. In the design I have been given, the column header will not be shown, and I need to be able to give the user to sort this column, by simply just clicking any where on the column.
