Hi,

Looks like, using the VirtualQueryableCollectionView, it is possible to lazy load the data if it is flat, but it is not possible if the data is displayed hierarchically. That is, using VirtualQueryableCollectionView, if GroupBy is done for single\multiple columns, the grouping is done only of the initial few records, obviously, as only few records are loaded initially by the VirtualQueryableCollectionView.

If there are multiple groupings then there is a hierarchy, and one can drill down subgroups step by step. I wanted to know if there is a way with GridView to lazily load the subgroup items.

Any suggestions will be helpful.

thanks

How to do this?

Hello,

we discovered an issue when having a TileList-Control inside a TileView. The reorder doesn't work, the items just disappear...

Please look at the following example code:

I just upgraded to the latest release of UI for WPF (2018.3.blah blah).  So far everything has been working fine.  But today I invoked a bit of my code that uses RadOpenFolderDialog.  The code is pretty simple:

            var dlg = new RadOpenFolderDialog
            {
                InitialDirectory = Settings.LibraryFolder,
                Multiselect = false,
            };

(I have verified the "Settings.LibraryFolder" points to a valid, existing folder at the time this function is called)

It then throws an exception.  The outer exception message is this:

    "Provide value on 'System.Windows.Markup.StaticResourceHolder' threw an exception."

The inner exception message is this:

    "Cannot find resource named 'BreadCrumbBarItemCustomStyle'.  Resource names are case sensitive"

I do not now, nor have I ever had a resource of that name so I have to assume this is something inside the Telerik release that was inadvertently removed.  Can you help me?

I don't know if it is relevant but early on in my app I use the StyleManager to set an application theme

            StyleManager.ApplicationTheme = new Windows8TouchTheme();

Also I am *NOT* using the "NoXaml" approach

Help...?

I have combined RadAutoCompleteBox with Combobox with multiple selection mode. When I select item from drop down of combobox the item gets added in the autocomplete box and the remaining portion of autocomplete box will be used for searching. But in this case I am not able to select the added items.

See attached screenshot, here the 2 items which are already added named TestPalga2 and TestPalga3 cant be selected. I want these items to select and remove on delete button press of keyboard.
