title: Unable to find the checked items in checked combobox
body: <p>I am using a checked combobox for selecting multiple items. Following is the code am using</p>
  
  <p><strong>ASP.Net</strong></p>
  
  <pre><code>&lt;telerik:RadAjaxPanel runat="server" ID="RadAjaxPanel1"&gt;
    &lt;telerik:RadComboBox ID="cbo_tagtofilelist" runat="server" CheckBoxes="true" 
  Style="width: 157px; height: 15px" ExpandDirection="Down" EnableCheckAllItemsCheckBox="true" 
  value="date" Skin="WebBlue"&gt;
    &lt;/telerik:RadComboBox&gt;
  &lt;/telerik:RadAjaxPanel&gt;
  </code></pre>
  
  <p><strong>VB.Net</strong></p>
  
  <pre><code>  Private Sub lnkfiletag_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles lnkfiletag.Click
          ShowCheckedItems(cbo_tagtofilelist)
   End Sub
      Private Shared Sub ShowCheckedItems(ByVal comboBox As RadComboBox)
          Dim msSQL As String = " insert into selecteditems( fileid, name ) values"
          For Each chkeitems As RadComboBoxItem In comboBox.CheckedItems
              If chkeitems.Checked = True Then
                  msSQL &amp;= " ('" &amp; fid &amp; "', '" &amp; chkeitems.Value &amp; "'),"
              End If
          Next
          msSQL = msSQL.Substring(0, Len(msSQL) - 1)
          con.OpenConn()
          con.ExecuteNonQuerySQL(msSQL)
          con.CloseConn()
     End Sub
  </code></pre>
  
  <p>But using this code I am unable to find the selected items and insert into the database. Item count always be <code>0</code> on button click, what am I doing wrong with this code</p>
