Forms Data Controls :: How To Manually Populate A Listview Control Without A Database Connection
Oct 10, 2010
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. The problem now is that the page does not communicate directly to the database. Instead, I use HTTPrequest to get all the user names from a different sever. Now I want to populate the listview control w/ the response that I got (and not directly from the database).

I am using VS2008 and oracle 10g ODP.Net. The oracle database that I used in the connection is working and tested it using sql plus.The connection string when used in a GriDView works perfectly. Now when I created a new listview control with the same connection it gives an error.Database schema could not be retrieved for this connection. Please make sure connection settings are correct and the database is online

I have a ListView tied to a DataSource, included in the layout is a Literal control. I want to be able for the user to click the Select button, and then I want to populate the Literal control with some Data. I have it working, but I have to click the Select button twice to get the data to show. My code is below.
Here is the html
<asp:ListView ID="ListView1" runat="server" OnItemCommand="ListView1_ItemCommand" OnSelectedIndexChanged="ListView1_SelectedIndexChanged"
DataKeyNames="TxnID" OnItemCommand="ListView1_ItemCommand">
<LayoutTemplate>

My issue is that the first row of data in my db table does not seem to be output to my ListView control when I run the page. The first item in the ListView control is the 2nd row of my db table.
If I execute the stored proc listed below in SQL Server Mgmt Studio all rows are returned to the query results window.
The ListView control is defined as follows:

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 want to name the headers of the ListView control acording to values of the first rows of a table in the database. This I want to do because the number of columns varies for each cutstomer and also the name of the column.

I have anested ListView control. I also implemented a jQuery to automatically expand the TextBox control inside of the nested ListView Insert Template. The problem is, when the Textbox expand, the outer ListView control is not; therefore, the Textbox control expands underneath the buttons of the outer listView control. How do I expand the outer ListView control as the nested ListView textbox is automatically expand? One great example is in Facebook where if I add a response comment, it'll automatically push any comments below mine down. If nested Listview control is not the best way to do this, what are my options?

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]...
how to bind the results datatable to lvdatasource. I tried a few different ways to do this with no luck. Maybe the syntax I trying to use is incorrect.
