I try to use a DataViewManager to filter data in a dataset, but somehow it does not work. The code below produces the error "A field or property with the name '< any field>' was not found on the selected data source". However, when I replace "GridView1.DataSource = dvm" with "GridView1.DataSource = ds" it works.

i have a dataset which contains some data.
let dataset have some columns one among them is " Type "
let the values in column type be type1,type2.type3 and so on
now if i want to filter dataset which contains only type3
I have a form that has dropdown box and user can either select Store Associate or Store Manager, when they click on either, I have GetASsociate function that pulls data from sql database. What i am trying to figure out how to do, is that if they say select Store Manager I want to filter what data to pull from that sql table that has all associates in it, so I was trying use an 'expression' statement to stay if Store Manager was selected, only pull me back the store managers from that table. Then same thing for if they selected STore Assoicate, then only bring me back teh store assocites from that table. But the expression statment does not appear to be working.

View 1 RepliesI have an application that needs to read data from a view and do some extensive manipulation prior to delivering it to a chart control (without modifying the original data in the database). I have the chart control on the page, and in the code-behind I've built a dataset which I load and manipulate programmatically to have the table, columns and rows needed (no datareader involved) I'm having considerable trouble binding the chart to the 'in memory only' dataset.

View 2 RepliesI am having some difficulties with a particular task. I am creating a support desk intranet application and I am trying to write a method within a class within a namespace which will form a generic database connection which can be called from any of the aspx pages so that I have the dbconnection logic in one place; you know, going along with the 'DRY' (Don't Repeat Yourself) mantra.
The Namespace:
SUPPORTDESK.SQL.dbconnection.pullData()
Objective of the method:
To provide any aspx code behind file with an SQL Server 2005 Express Connection and if possible return the data from an SQL Query. This is where I need advice do I create the method such that it simply forms the connection and returns a DataSet or that it returns an SQLConnection object? If i've got things back to front and upside down don't worry I'm a beginner with ASP.NET. The Method so far:

If I'm on the right track how do I access the data returned in the DataSet?
I'm hoping someone can point me in the right direction. I will be as detailed as I can in explaining the issue;I have a dataset I have instantiated in a class file (vb.net), and fill the data succesfully. That data is then dumped into an excel file. What I need to do is to go through all the data in the dataset, and directly update the database, changing a "status" column from "pending" to "processing" based on the store number. As I am new to datasets (relatively speaking, of course), I am not quite certain how to accomplish this task. Below is the code I have so far:

If anyone could provide sample code to use, or could provide a quick bit of code I could just copy and paste in and test,
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?
I am trying to return a dataset. I must be doing something wrong. The returned dataset in this sample code indicates there is a datatable, Users, but there are no datarows. What am I doing wrong? This example is only using the rows.count, but of course I really need to use the whole datatable as the datasource for a gridview.
[Code]....
Public Function getmyds() As DataSet
Dim dsUser1 As DataSet = New DataSet()
Dim tbUser1 As DataTable = dsUser1.Tables.Add("Users")
tbUser1.Columns.Add("UserName")
tbUser1.Columns.Add("Days Remaining")
tbUser1.Columns.Add("UserAccountControl")
Dim rwDefaultUser1 As DataRow = tbUser1.NewRow()
rwDefaultUser1("UserName") = "John Smith"
rwDefaultUser1("Days remaining") = 100
rwDefaultUser1("userAccountControl") = "Enabled"
Return dsUser1

I have seen this question asked about a half a million times and I still haven't been able to get my solution working by reading there answers.
First off I am using visual web developer 2008 express. I am brand new to asp.net net so me="nub"
I watched some videos on how to setup a website soloution and I did got a free cs and all that got it working. I installed the Ms Membership for loging in and out of my website. I got all that working. I installed the database for the membership on a sql server followed the video for doing that and everything works.
I then decided to do something so simple. I thought it was so simple.
I created a dropdown list using the control and I wanted it to go out to my database on my sql server and get my account numbers and filter them by using the current membership member that is logged in. I see that I can display my current user like this
<asp:LoginName ID="LoginName1" runat="server" />
I can see my user log in and out of the website and that seems to work fine.
So here is what my current dropdown list looks like I say current because I have tried this a ton of times with different parm options but none work.
