Hi Telerik,
I'm using C# and and RadPageView NavigationBar component for my WinForms application.
I think I'll give a background story first.
I implement a RadPageView with NavigationBar, and also implement a search bar between the hamburger menu and the RadPageView items
The item's is populated from a class
The "search menu" is used to filter the displayed menu
And when I clear the search menu's filter, the RadPageViewItems is re-loaded with the previous class data. But, it takes a long time due to a lot of records (FYI, i have ~1000 menus that equivalent to ~1000 RadPageViewItems)
Is it possible to improve the load speed? Like, maybe, any mechanism that stores the fully loaded menu as a local-storage in RadPageView's function/module that I should call when the search menu is cleared after it has been filled?
Thanks in advance!

Hello RUNSystem,
I appreciate the provided details.
Having ~1000 pages in the control will take some time to repopulate the control. I am assuming that when the user is typing in the custom search area, items are removed or added to the Pages collection. The control does not provide a mechanism to store the pages to improve the performance in this specific scenario. What comes to my mind is to hide the items instead of adding and removing the items.
Here is what I have in mind:
foreach (RadPageViewPage page in this.radNavigationView1.Pages)
{
//search criteria
if (page.Item.Visibility == ElementVisibility.Visible)
{
page.Item.Visibility = ElementVisibility.Collapsed;
}
else
{
page.Item.Visibility = ElementVisibility.Visible;
}
}The control contains a large number of pages, but still, I hope that this will improve the performance in your application.
