    <p>Hi I am inserting into a table then reading everything back into a <code>ListView</code> When I re-open the program I see the data I just saved in my <code>ListView</code>, but this record is not showing in my <code>ListView</code> at the time of saving (although it is saved in the table). </p> <p>I am using </p> <pre><code> listView.Update() </code></pre> <p>as well as</p> <pre><code> listView.Refresh() </code></pre> <p>but it does not seem to work. I am just using a <code>SELECT</code> query to read data off the <code>datareader</code> and store it in my <code>listView</code> as follows (which is working properly)</p> <p>The only problem is that the listView is not refreshing immediately, but it works when I close/open the program</p> <p>here's the code I am using at the end of my Save method. basically these two methods get called </p> <pre><code> Private Sub SetColumns() Dim lstpenalty As New ListView() lstpenalty.Items.Clear() lstpenalty.Visible = True lstpenalty.Bounds = New Rectangle(New Point(390, 55), New Size(560, 379)) lstpenalty.Name = "lstpenalty" lstpenalty.FullRowSelect = True lstpenalty.View = View.Details lstpenalty.GridLines = True lstpenalty.Items.Clear() lstpenalty.Columns.Add("a", 75) lstpenalty.Columns.Add("b", 70) lstpenalty.Columns.Add("c", 105) lstpenalty.Columns.Add("d", 98) lstpenalty.Columns.Add("e", 90) lstpenalty.Columns.Add("f", 105) Me.Controls.Add(lstpenalty) LoadPenaltyList(lstpenalty) End Sub Private Sub LoadPenaltyList(ByRef listView As ListView) Dim gDR As OracleDataReader Dim cmd As New OracleCommand Dim lstpenaltyview As New ListViewItem Try cnn.Connect_to_Oper_Agent() cmd.Connection = cnn.cnn listView.Items.Clear() cmd.CommandText = " select a," &amp; _ "b, " &amp; _ "c, " &amp; _ "d," &amp; _ "e," &amp; _ "f" &amp; _ " FROM myTable" &amp; _ " commit" gDR = cmd.ExecuteReader() While gDR.Read lstpenaltyview = listView.Items.Add(Null_To_String(gDR("a"))) lstpenaltyview.SubItems.Add(gDR("b")) lstpenaltyview.SubItems.Add(gDR("c")) lstpenaltyview.SubItems.Add(gDR("d")) lstpenaltyview.SubItems.Add(gDR("e")) lstpenaltyview.SubItems.Add(gDR("f")) End While listView.Update() Catch ex As Exception MsgBox("There was an error... -&gt; " &amp; ex.ToString) Finally cmd.Dispose() cnn.Close_Conn() End Try End Sub </code></pre> <p>Thanks for your help </p>

    1. COThose two methods just redraw the control with its current data. You need to populate it again with new data.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
