ADO.NET :: Retrieve Values From A Dataset VB.net?
Feb 21, 2011
how to retrieve a value from a typed dataset. I am trying to retrieve a value from a row within a row return from a tabale adapter method. Example:
Dim transAPI As New PN_TransactionBLL()
Dim trans As PN.RetrieveGEmailDataTable = transAPI.getGEmail(itemtId)
The tabeadapter method retrieves 1 row of data and I would like to pull the values retrived such as "trans.rowproperty"(if thats the correct syntax) where "rowproperty" would contain the actual value returned.

I'm building a Remoting Demo, and here's my scenario:
There are 4 projects:
ServicedCOM: This project I've built a ServicedComponent, this component using for access data from database.
RemoteLoader: I using this to load ServicedCOM to RemotingServer.
RemotingServer: This is an console application, and this application can be running from another computer.
WebApp: Client, this is inteface using for End User.
and my results: I can access and retrieve data with function is called SpeakHello (test function), but I cannot do the same thing to get sectors using this model, I think I'm doing something wrong. and here's my code snippet:
1. I have a ServicedCOM and a function to get Sectors is called GetSectors (I test OK)
[Code]....
[Code]....
2. I have a Remote loader
[Code]....
3. And here's RemotingServer
[Code]....
4. And the last is Client

Is there any method by which we can retrieve random data from a dataset or rather directly from a table.
For example, I have around 30 questions in my table, I just wanted to display 20 among them and that too in a random order without the same item repeating. Can we achieve this using SP or through some Dataset manipulation?

Then when the button click event is trigger i need to get all the records from GridView. But when i debug and check i found that the GridView.DataSource is become nothing. how should i get all records from the GridView and assign to dataset. I'm using VB.net to work on.

I've figured out how to use a repeater field, now what I want to achieve is a "total" figure for the column, and this figure needs to appear the footer.
Back in ASP 3.0, I would simply create a variable, and on every step as I looped through the recordset, I would add the current to the variable, including its original value. At the end, I'd have the total. Apparently I can't figure out how to do the same thing in ASP.NET.
This is what I'm doing (which doesn't work):

I am creating an ASP.NET application that allows the user to add form elements to a page within a form. When the page is posted (via the submit button) I need to loop through ALL the posted values in the form and get the values.
I can't check for specific values as I don't know how many there will be or what they will be called.
Could someone point me in the right direction of getting ALL posted values so I can loop through them?
p.s I was looking in Request.Form but couldn't see anything obvious to use.
