Forms Data Controls :: Multiple Records Update With Requirements?
May 11, 2010
Is it ok to do multiple records update with the following requirements and be safe that the operation will not get timed out? A user requiring me to do the following using a web form:
I. Display a list of accounts in a GridView for multiple records insertion with no client side validation. Each account will accept new reading and posted date values.
II. Once the user presses the submit button, the following steps will be performed for each record at server side:
1. Check if new input data is for new or old period. A checkbox is to be selected in the form.
2. Check if new data has existing related records. Else this is first time insertion; get consumption result and save to db.
3. If records found, get previous reading and date.
4. Check if new reading and date is greater than previous reading/date else should inform the user.
5. Get new consumption = new reading - previous reading and some other operation.
6. A join select statement will be used to get the lowest and highest values (consumption) for current account.
7. Compare the new consumption result with previous consumption to give a status indication for new reading as either high, low or normal to be saved into the db. (# 6 values will be used here)
8. If everything goes ok, save new data into 3 different tables.
9. Display the GridView with new data.
The SQL server and the hosted page are in two different servers.

Update multiple records with subquery

I have an inventory page with a gridview that shows 1 item per record, each item starts with a checkbox in the gridview. Currently users can select multiple records and hit the order button and everything has worked well. Now I have multiple pages in my gridview, and if a user selects a few records from the first page, and then goes to the second page, all the records (checked checkboxes) disappear from the first page.

I know how to bind the columns to a grid and its no problem to create such a dropdown list with the content for me, too. But i dont know how to sort the complete datatabl after changing one value of one dropdown listbox.
So, how can i resort the values of a datatable column based on a given value and the datarow id?

I've got a single table, with project information and schedule information. To make the data easier to present, I created a tab control with two panels (a detailsview in each). The first tab is for project info, the second tab is for schedule info (again, all fields in the same table). The problem is, if i change info in both tabs, and then hit the update button, only the data from one tab is added to the table. I think this problem is simple to fix, and boils down to the way I have the page organized, but I can't quite figure it out.
I've boiled my code down to the following conceptualized structure:
[code]....
When you click the update button, you return to the listview, but with only the information from your current tab saved. How can I get it to update from both detailsviews?

I have a Vendor table and a Vendor Contracts table.I have a ddl outside of formview that selects VendorID and VendorName from the Vendor table.
FormView gets the VendorID from the ddl attached to the Vendor table and populates formview with records from the Vendor Contract table with the same Vendor ID. The primary key of the Vendor Contract table is VendorContractID.
This works fine as long as there is only one vendor contract. If there are multiple contracts, the ddl shows the vendor twice and aborts when selecting.
If there is only one vendor contract, the vendor is listed once in the ddl and selecting it causes the record to display in formview and is updatable.This is related to an earlier post today solved by PeteNet.

Woker A does Offset printing with quantity 100, C does Offset printing also but with quantity 950, if we sum quantity A and C do will be over 1000 Ã message box: warning

However when I bind the dataTable that I return it is showing multiple duplicates, meaning I see each record appear 8 times in the gridview, has anyone seen this or know what I'm doing wrong?

I am building a retail shopping website and want multiple db records per row - e.g. 2 records per row side by side. Each record will have an image, a couple of labels from the database to state Item title / name, description etc and I need to add a textbox for the quantity. In clothing section a radio button for size and another textbox for item colour. I will then add a button (any button) to gather the info (recordID and textbox input) and take me to the shopping cart.
Problem: In ListView I get the multiple records but can't get the data from the textboxes: In Gridview I can get the textbox data but can't get multipe records per row.Which grid should I use to get both of these features working?
