If a formula contains a named range as an argument, its value may not get updated properly in the following scenario:

In the formula: =SUMIF(A1:A4, 3, ColumnC), ColumnC is a named range refering to C1:C4. Range A1:A4 contains the values 3, 2, 2, 3, which will avoid a circular reference. The formula is entered twice, in C2 and C3. Note that these cells are part of the range ColumnC refers to. When you refresh the formula in C3 (enter edit mode, then press enter), it will calculate correctly, but the formula in C2 will be recalculated to an error. If you refresh the formula in C2, the formula in C3 will be evaluated to an error.

I use RadWindow as the main window for my application (primarily because I want to embed a menu in the title bar).  This works well except our users have reported a bug where they are unable to use hotkeys following activating the application from the TaskBar.

A typical scenario:

* minimise the application using the minimise button

* some time later, activate the app by clicking on the TaskBar icon

* Press CTRL+N hotkey combination which should execute a command

I have created a sample application that shows two windows: a regular Window and a RadWindow.  They both contain input bindings for the Ctrl+N combination.  When the regular window is activated from the taskbar, the input bindings work, but when the same sequence of events is performed on the RadWindow the input bindings do not work.  Clicking between the windows does work - it seems the problem is only related to application activation.

On a related note, both windows contain a TextBox control.  If text is highlighted in the regular window, the highlighted text is maintained and redisplayed when the window is activated.  This does not work for the RadWindow.  As it relates to keyboard focus, I wonder if the problem is related.

I have created this timeline control out of a combination of different controls.  But I get asked for this same kind of setup from different companies for different reason. I have created this control using your TreeListView to show the headers in the hierarcy while for Layer Num items, there is a list to the right which holds a list of MediaItem objects.  It works but not very efficient and is missing much key functionality. And I thought because you already have controls that are similar, it wouldn't be a huge reach for you to make on like this.

So there could be two modes for this.  The editing mode where the user is dragging/dropping media items on each layer item, rearranging, setting the length of media, etc.  They could then hit PLAY like a Movie Maker and see a preview on a different control of what is being played.  Once this is saved, it could be used in another way.

So in the readonly mode, all the items would be feed in as a hierarchtial collection.  It would decribe how many levels there are and the names and order of the items.  And then it would also have all the MediaItems related to each Layer Num.  And then it would constantly be fed what the current time is related to this batch of items playing.  The user doesn't hit PLAY in this mode but rather just sees a read only version of what is being played and watch the line goes across.

I think this would be a very welcomed control to your lineup.   Because anyone who wants to make a media editing program, audio editing program, and even showing a schedule for items that happens every 30 seconds in different locations while getting a constant status of the current time would find this  invaluable.

Hi there,

If you want to change the hover colour of the RadHyperlinkButton font, you currently need to create a copy of the control template and override the styles that you want to change.

It would be much easier for developers if the hover font properties could be surfaced into the VS property editor so we can simply select a colour, font weight etc...

Hi,

we are using our own IPagedCollectionView implementation in combination with the RadDataPager control as shown in the attached example project. Basically, we bind an instance of the PagedCollectionView that is provided by our ViewModel to the Source property of the RadDataPager.

Recently we started to take implementing the Dispose pattern a bot more seriously and also added the IDisposable interface to our custom PagedCollectionView (in order to Dispose some internally used CancellationTokenSource).  Today we realized that the RadDataPager now calls Dispose() on the PagedCollectionView  instance although not being its owner. This happens as soon as the DataPager itself is Disposed e.g. by switching modules (and thus loading a new DataTemplate) in our multi-module application. Coming back to the module will then cause the disposed Collection to be used again, potentially causing ObjectDisposedExceptions etc.

What I would expect: The RadDataPager control should not call Dispose() on its Source collection if it is Data-Bound to a ViewModel since that might leave the ViewModel in an invalid state that can cause Exceptions later on.

The problem exists with .net 6 and .net Framework 4.8 as well as with versions 2022.3.1109 (Xaml, see Example project) and 2022.2.621 (NoXaml)

Hi Team,

having a "Signature" component in your WPF package like you have in your Blazor package will be very interesting.

Can be reproduced in the WPF demo (Windows8 theme): the error description tooltip appears on the left of the control and with the red arrow on the left (see attachment). The tooltip should appear on the same side of the red adorned element (the red triangle, top right corner) and the tooltip arrow should point the control.

So, if there is a solution to this, I haven't found it yet after scouring the documentation and the internet.

Using your example in the WPF Demo, I created a custom object for my items that I bind to the RadNavigationView.ItemsSource. Yours was called NavigationItemModel. Mine is called ShellMenuItem. ShellMenuItem inherits from UserControl, and implements INotifyPropertyChanged, and ICommandSource. All bindings to my properties are wired up in the xaml and work great (EXCEPT FOR THE ISEXPANDED PROPERTY. Next, I have several properties that are pulled from a database, or can be set programmatically in code, like Id, ParentId, Header, NodeType, TargetPageType (Page, Window, etc), TargetViewModelType, etc... Just standard properties. These are so I can programmatically send these dynamic items menu items, pulled from a database, to the correct View and ViewModel. ALL OF MY PROPERTIES WORK FINE, and when I click on a menu item, if it is a page, it opens in the frame, if it is a window, it opens a window, etc... Everything works fine, except the IsExpanded. So, here is the issue. I have a property on ShellMenuItem named IsExpanded. When I try to set this property, the ShellMenuItems do not collapse or expand. Again, I have INotifyPropertyChanged implemented.

On the form, I have a toggle button to expand/collpase all items in the RadNavigationView. I have it's Checked event bound to a command in my ViewModel. 

<ToggleButton Content="TestExpandAll">
     <i:Interaction.Triggers>
          <i:EventTrigger EventName="Checked">
               <i:InvokeCommandAction Command="{Binding ElementName=_this, Path=DataContext.CmdExpandMenus}" PassEventArgsToCommand="True" />
          </i:EventTrigger>
      </i:Interaction.Triggers>
</ToggleButton>

public ICommand CmdExpandMenus { get { return new RelayCommand<RoutedEventArgs>(OnExpandMenus); } }

This fires correctly in my code, at which point I loop through the RadNavigationMenu's ItemsSource and set each property to IsExpanded = true; As shown below. The button should expand all items if the togglebutton state IsChecked, else, it should collpase all items. I have also tried to loop through the actual bound list which likewise, does not work. I can not find a way to get at the entire list of RadNavigationViewItems or even cast my items to a RadNavigationViewItem, even though the ItemContainerStyle's target type is RadNavigationViewItem. There has got to be a simpler way to achieve this. 

        private void OnExpandMenus(RoutedEventArgs? e)
        {
            //foreach (var item in this.StaticMenuItems)
            //{
            //    item.IsExpanded = true;
            //}

            foreach (var shellMenuItem in this.MainMenu.ItemsSource)
            {
                var itm = shellMenuItem;
                var itmType = itm.GetType();
                //itmType is ShellMenuItem
                var menuItem = shellMenuItem as ShellMenuItem;
                //var targetType = this.MainMenu.ItemContainerStyle.TargetType;
                //targetType is RadNavigationViewItem
                menuItem.IsExpanded = true;
            }
        }

I have easily achieved this effect on many other controls, and you even have predefined Methods to perform this on controls such as RadTreeViewList.

    void treeListView_DataLoaded(object sender, EventArgs e) 
    { 
        treeListView.DataLoaded -= treeListView_DataLoaded; 
        treeListView.ExpandAllHierarchyItems();    
    } 

Can you add a method to the RadNavigationView to ExpandAllHierarchyItems(true/false) or just add 2 methods...

ExpandAllHierarchyItems() and CollapseAllHierarchyItems()

If this is not feasible, then you should update your demo to show how to accomplish this with a custom menu item. Im sure I could make my ShellMenuItem inherit directly from RadNavigationViewItem but in my control library, I dont have any references to Telerik because there are applications that use ShellMenuItem that do not use Telerik at all, and we shouldnt have to make our generic controls inherit from a 3rd party control to make this work. It seems to me that if you have a control that allows a hierarchy of items, and those controls/classes can be expanded or collapsed, then you should ALWAYS add the methods above to those controls/classes. Or perhaps you could create an interface named IExpandable, and any control that you guys create that can be expanded/collapsed, could implement that interface and have access to the ExpandAll/CollapseAll funtionality.

Thanks,

In Windows 11,  when mouse over top level window title bar maximize box,  there should be snap layout drop down, but for any child window there should not be snap layout drop down.

I've tested the following 4 cases and all of them works fine

   1. win32 project

   2. MFC project

   3. general Winform project

   4. general WPF project.

but for Telerik WPF project which use RadRibbonWindow as main window, the behavior is wrong. as attached video shows
