    <p>I'm using a custom footer on my View Control; there I have for example:</p> <blockquote> <p>Displaying <strong>1</strong> - <strong>25</strong> of <strong>34200</strong></p> </blockquote> <p>My underlying View is Categorized so the total of entries should include categories as well. So far the only way I'm able to find the total of entries including categories is using NotesViewNavigator; however, performance is not acceptable since it's taking around 27 seconds to compute this piece of code.</p> <p>I'm sure the issue is with line <code>var nav:NotesViewNavigator = view1.createViewNav();</code> because I added some debugger info:</p> <pre><code>start = new Date().getTime(); var viewPanel1:com.ibm.xsp.component.xp.XspViewPanel = getComponent("dataView1"); var nav:NotesViewNavigator = view1.createViewNav(); if (viewScope.VendorSrch == "" || viewScope.VendorSrch == null){ var total = nav.getCount(); }else{ var total = viewPanel1.getRowCount();// View can be filtered by user as well (using categoryFilter property) } var from =(viewPanel1.getFirst() &lt; total? (viewPanel1.getFirst() + 1 ) : total); var tmpTo = viewPanel1.getFirst() + viewPanel1.getRows(); var to = (tmpTo &lt; total? tmpTo : total); var elapsed = new Date().getTime() - start; print(elapsed + " ms"); "&lt;/b&gt;Displaying &lt;b&gt;"+ from +"&lt;/b&gt; - &lt;b&gt;"+ to + "&lt;/b&gt; of " + "&lt;b&gt;"+total+"&lt;/b&gt;" </code></pre> <p>Does anyone know how can I improve this piece of code?</p> <p>Please note documents in this View have Readers fields as well which may be impacting the performance of this operation.</p>

    2. COThanks for the link @jjtbsomhorst. I did try with `nav.setEntryOptions(NotesViewNavigator.VN_ENTRYOPT_NOCOLUMNVALUES);view1.setAutoUpdate(false);nav.setBufferMaxEntries(400);` but I'm getting same results; maybe 0.5 seconds less. I think this makes a difference when you are within a loop.

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.
