This is what i want to do with my website. I want to pull data from an access query and and load it into a listview table. The user will sort through the data on the website and remove the rows she doesn't want. After the user is done, they will click a send button that will email the data to the appropriate party.I have read the access query data into a data table. I have the list view table built, but I am unsure how bind the data table into the listview table. Is this the best route to go? Will binding the datatable to the listview table allow the user to delete rows out of the datatable?
Protected Sub btnView_Click(sender As Object, e As System.EventArgs) Handles btnView.Click
Dim query As New QueryBuilder.SelectQuery("qryVendorReport")
'Fill data table with vendor information
Dim sample As String = ""
Dim results As New DataTable
results = (db.fillTable(query.toSelectQuery))
[code]...

No data is loaded when the button (btnSearchWrd) is clicked. Instead, in the Firefox Error console, it listed these two errors:Error: item is undefinedError: ys.WebForms.PageRequestManagerServerErrorException: Could not determine a MetaTable. A MetaTable could not be determined for the data source '' and one could not be inferred from the request URL. Make sure that the table is mapped to the dats source or that the data source is configured with a valid context type and table name, or that the request is part of a registered DynamicDataRoute.
I'm comfortable populating dropdownlists in a standard webform, but I seem to be having trouble populating them from within a gridview or listview.I know that I'll probably need to use the find control method, I've had a stab at it with the following:
[Code]....
The purpose of this is to allow someone to look at a bunch of records, and in a dropdownlist add an item to a group, but this "group" is in a separate table, so I want to take whatever value that select in the dropdown menu, lookup their user id, and add both bits of information to the other table, so it's technically not even editing, even though i suspect I'll need to use the edititem template?
I have no problem when paging my FormView, the dropdownlist does not read the next record and keep the value of the first loaded record? All other textbox control behave normally and move from record to record excepted the ddl??Here the code.
Public Sub DoData() Dim myConn As SqlConnection = New SqlConnection(ConfigurationManager.ConnectionStrings("LocalSqlServer").ConnectionString) Dim myCommand As SqlCommand = New SqlCommand("SelectSupplier", myConn) myCommand.CommandText = "SelectSupplier"

I'm currently developing an ASP.net application w/ VB as the code behind. I have a page that shows all the user name currently assigned to the system.

Now I want to populate the listview control w/ the response that I got (and not directly from the database).
