/* Improving performance on complex List item templates */
=== Overview ===
=== Lesson Technique 1: Loading UI content on demand ===
It was discovered that UI controls hidden with '''IsVisible=False''' remain in the UI tree. To improve performance on highly complex item templates, like UBIKTaskItem, rendered repeatedly such as in ListViews, a workaround can be applied to only load the UI content when the '''visibility''' binding condition is met.

=== Lesson Technique 2: Reducing background Binding errors ===
Complex item templates such as UBIKTaskItem were found to produce large numbers of '''errors''' while rendering, likely as bindings are being resolved before the relevant '''viewmodels''' can be loaded by the client. While these '''errors''' are temporary and not visible to the user, the cumulative effect of numerous binding errors raised while rendering items can be felt when navigating to pages with large numbers of items.

{{Attention|Unfortunately, these bindings errors are not normally logged in the UBIKDebug.log. Therefore, the recommendation is to use the following technique when whenever using a ContentControl or controls:ContentControl.}}
