The client wanted to see "n/a"&amp;nbsp;showing for combo boxes which have no value selected in them.&amp;nbsp; Therefore, I implemented the TopMostItem property of a StrataFrame Wrapped DevExpress ComboBoxEdit controls I have on the form.&amp;nbsp; My settings are as followed: TopMostDescription = "n/a", TopMostDropDown = is blank, TopMostValue = 0.&amp;nbsp; The form works great on my development machine, but I am getting the error message below&amp;nbsp;on the clients' computers.&amp;nbsp; Can you tell me what I am missing?&lt;/P&gt;&lt;FONT size=2&gt;&lt;FONT size=2&gt;&lt;P&gt;Method not found: 'Void MicroFour.StrataFrame.UI.TopMostListItem.set_TopMostDropDown(System.String)'.&lt;/P&gt;&lt;P&gt;Exception (MissingMethodException): Source="Project Tracker";

The TopMostDropDown property was added with version 1.6.1 (or somewhere around there), but the version number of the assemblies has not changed since v1.6.0.0, so most likely, your setup program did not update the StrataFrame assemblies within the GAC.&amp;nbsp; Replace those assemblies and you should be good to go.</description><pubDate>Thu, 08 Nov 2007 14:25:36 GMT</pubDate><dc:creator>StrataFrame Team</dc:creator></item></channel></rss>
