Is it possible to populate a listview with a dataset? I have a function that returns a dataset. Why im asking this is because my SQL is quite complicated and i can't convert it to a SQLDataSource...
Public Function getMessages() As DataSet
Dim dSet As DataSet = New DataSet
Dim da As SqlDataAdapter
[code]...
Current code:

It seems that it doesn't have datasource that I usually do. How could I?
I've got a SqlConnection with a sqlquery that may not bring any results. On the rare occasion this happens, I have another sqlquery and another connection to the database. There has to be a better way to do this, no?
On a side note, is this best to close the connection after .Fill? I assume so, but haven't seen it used anywhere.
SqlConnection dbSqlConnection = new SqlConnection(--);
SqlDataAdapter dbSqlDataAdapter = new SqlDataAdapter(sqlquery, dbSqlConnection);
DataSet dbDataSet = new DataSet();
dbSqlDataAdapter.Fill(dbDataSet, "popGrid");
dbSqlConnection.Close();
if (dbDataSet.Tables["popGrid"].Rows.Count == 0)
{
SqlDataAdapter newSqlDataAdapter = new SqlDataAdapter(sqlquery2, dbSqlConnection);
newSqlDataAdapter.Fill(dbDataSet, "popGrid");
dbSqlConnection.Close();

View 1 RepliesHow do I populate a dataset with an Objectdatasource?
The reason is I have an Objectdatasource on a page which is populating a GridView ok.
I want to use a Dataset to control the DayRender of a Calendar Control and don't want to query the database again as the right date info is already in the Objectdatasource.
So can i populate a dataset with the objectdatasource ??
I need to asynchronously retrieve several resultsets which I store in DataTables and add these DataTables to a DataSet. When the final DataTable is filled and added to the DataSet the page must then continue processing utilizing this DataSet I have figured out how to implement delegates to asynchronously retrieve my DataTables but I'm unclear how to add them to a DataSet in a thread-safe manner. How is this best accomplished? Before processing I know how many DataTables there will be, so what is the best way to track the progress of the asynchronous retrievals and allow the page to continue only after I have all of the data?

I have always had problems with creating loops so here I go again.
I have a dataset populated with 1 column and multiple rows. What I am trying to do is create a page that will be used for emailing multiple users. The names will need to be separated by a semi colon.
My stored Procedure returns two tables say table1 and table2. When I try to fill the dataset, table1 is filling properly and table2 filling only one row of the table remaining rows coming empty. There is no error when I compile the code. And the output is an empty page.
Here the code I've used
SqlConnection cn = new SqlConnection(ConfigurationManager.ConnectionStrings["NorthwindConnectionString"].ConnectionString);
SqlCommand cmd = new SqlCommand("TABL", cn);
cmd.CommandType = CommandType.StoredProcedure;
SqlDataAdapter dad = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
dad.Fill(ds);
GridView1.DataSource = ds;
GridView1.DataBind();
i have application with 2 cascading dropdownlists that got populated using web service, when a value was picked in the first one the second filled with values, now when the second one got selected i want to poulate listview with images links.
View 2 RepliesI am using a ListView and would like to implement the switch from read only mode to edit mode for a ListView item on the client side. Some of this is discussed at: Inline form editing on client side
I am trying to do this by something like:
[Code]....
switchState is a Javascript function that simply hides/shows the DIVs with the readonly and edit classnames. In LinkButtonSave_Click I get the value from TexBoxName but it always contains the bound original value and not the edited value that was entered in the texbox.
Does ASP.NET not postback the textbox value because it is in the ItemTemplate or is it something else that's causing this problem? Could I use a Repeater instead to accomplish this?
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))

I need to bind my dropdownlist to my dataset that is returning application specific text values. But for purposes on that page, i need to assign the value to each one starting at 0 to the number of items returned from my dataset..
Example, if my dataset only returns 1 item, the value of that item needs to be 0

If my dataset returns 4 items, the value of those items needs to be 0 thru 3

Is it possible to assign values like that to a dropdownlist from the code behind?

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 populate a gridview within the listview.I amm taking reference from the article Populate ASP.Net ListView from database and Repeat columns horizontally using GroupTemplate.
View 1 RepliesMy problem is as follows:I have a gridview that get populated from a stored procedure in my MS SQL database. This gridview has a column that is a link field that I click to navigate to a new page that should display the correct info in the relevant labels.So the gridview returns say five diffrent rows of companies (and this work great by the way) and lets say that the 'company name' is the link field column that I meantioned earlier. So now I the company name and this navigates me to the Company.Aspx page, which so far is all working well.What I cant seem to get right is how to pas the correct row of the the passed dataset to display in the correct label fields, here is a brief snippet of what I mean:
if (Session["objDataSet"] != null)
{
DataSet dsCurrent = (DataSet)Session["objDataSet"];
