Populate Listview from Datatable

I am trying to populate a listview from a stored procedure, I can verify all data are being returned just fine but not populated properly in the listview.
I am trying to display 3 columns in my listview, but instead only the first column is showing.

here is my code:

Those are the only records in my table and the represent the ItemNo.
1- Anyone knows what wrong with the code above and not the Name and Qty fields are not showing the listview?
2- How can get rid of the ( ListViewItem: ) caption/header showing in the listview above?

DataTable dt = ds.Tables[0];

                // Clear the listview control
                lstItems.MultiColumn = true;


                // Display items in the ListView control
                for (int i = 0; i < dt.Rows.Count; i++)
                    DataRow dr = dt.Rows[i];
                    // Only row that have not been deleted
                    if (dr.RowState != DataRowState.Deleted)
                        // Define the list items
                        ListViewItem lvi = new ListViewItem(dr["ItemNo"].ToString()); //SHOWS
                        lvi.SubItems.Add(dr["Name"].ToString());  //DOES NOT SHOW
                        lvi.SubItems.Add(dr["Qty"].ToString());     //DOES NOT SHOW

                        // Add the list items to the ListView



What the code above shows when running it is the following:
ListViewItem: {12345}
ListViewItem: {56789}
ListViewItem: {12}

lstItems.DataSource = dt;

I already tried to bind its datasource = dt but it didn't work as the result showing are


Instead of actual values.
I am interested in knowing why my code above doesn't show all columns and only shows one column (one value). All values (rows) are showing properly in the datarow

Hi smaguire;

In order to display columns you need to set the ListView to Detail view, so try making the following change:

// Clear the listview control
lstItems.MultiColumn = true;
// Set to details view.
lstItems.View = View.Details;

I think that should get it to work for you.


I don't have the .View option! I am using ListView version but no .View property is available to me.


I was able to get the .View property to display, I had to remove and then add the reference pointing to it and the property showed just fine, however now it doesn't display anything.

The list is not populated. any thoughts? Is there a better way populating a listview from a stored procedure?
