Please refer to the attached gif file for better illustration.

Workaround:

    Private Sub RadGalleryElement_DropDownClosed(sender As Object, args As RadPopupClosedEventArgs)
        For Each item As RadGalleryItem In Me.RadGalleryElement1.Items
            item.VisualState = ""
        Next
    End Sub

Hello Telerik Team,

i hope you can help us with an scaling Problem on submenues.

On highdpi mode the width of submenues on the application menues grows.

We tried some ways to fix the size on dropdownopened event.

More details in attached gif and project.

Hi Telerik Support,

Here is a description of the environment I work with:

- Visual Studio 2019 (version 16.9.3)

- NuGet package is UI.For.Winforms.AllControls.Net50 (v2021.1.326)

- Project is a .NET5.0 class library.

When trying to add a RadDropDownListElement to a RadRibbonBarGroup, Visual Studio seems to encounter an error and a window pops up with the message "The connection to the server has been lost". Adding other types of elements to the RadRibbonBarGroup seems to work properly (I managed to add buttons without any issues).

I will attach a screenshot of the issue.

Thanks for your help !

Hello,

When using radsplitbutton in a ribbon, when the ribbonbargroup is collapsed due to a form too small, then the click event on the button part is not fired.

When clicking the button, the radsplitbutton look like it is "checked" instead, the popup is not open.

This has been tested in 2021.1.204.40, I apologize if this has been fixed in between.

Thanks

By default, the ImagePrimitive in a ribbon button is auto sized. If you want to disable the AutoSize property of the image and specify a specific Size, the AutoSize property gets serialized in the designer, but the Size is not. This leads to missing image after reopening the designer.

After saving the changes and reopening the designer the image is missing since its Size property is not serialized:

Please refer to the attached gif file.

Note: the developer should be able to select a tab at design time and add groups and items to each tab. Currently, a different tab can't be selected.

This is the behavior for collapsing the ribbon and showing the the small image for RadButtonElement: https://docs.telerik.com/devtools/winforms/controls/ribbonbar/designing-radribbonbar/using-large-and-small-images

A similar functionality should be available for the ActionElement in RadDropDownButtonElement and  RadSplitButtonElement.

When I use the Crystal theme on the ribbonbar items disappear from the backstage view.

I found the same behavior on your demo also. So I'm giving you the steps to replicate the behavior there. When I switch to other themes the issue does not seem to happen.

1. Go to the Ribbonbar First Look demo.
2. Switch the theme to Crystal
3. Go to the Backstage view and just move the mouse or hover over the Print preview
4. All items will disappear. The only way to get them back is to switch to another theme.

Please let me know if I can provide any other information to help resolve this issue.

Thank you

Eddy

Hi,

please see the attached sample and screen shot.

If application with Ribbon Bar is moved to a high dpi display (or started on a 4K display), two issues happen:

1. The title bar is not scaled (font) and has an ugly black line
2. The drop down element font is not scaled (the list itself is correct)

Martin

Hello,

you will find in attached image the problem for File Tab button regarding its look in the editor and when running the application. How can I resolve this difference ?

Best regards

Just a request to add in a RadFontDropDownListElement item to the RadRibbonBarGroup item list in the RadRibbonBar.

I am bypassing this by manually loading in the system fonts to a RadDropDownListElement but I could see the ease and appeal of having it already available. 

Dear,

look at video attached,

I'm using app theme resolution windows 7, but in RadRibbonForm the caption draw very awfull. This happens since always I use Telerik, but now I got some time to report to you.

ThemeResolutionService.ApplicationThemeName = "Windows7";
 
What I do?
Best,
 
Jeff

Please refer to the attached sample project and follow the steps from the gif file. 

You will notice that each time a random group displays only images (no text) when the groups don't fit in the ribbon's width.

Workaround:

        public MDIForm()
        {
            InitializeComponent();
            this.radRibbonBar1.RibbonBarElement.ItemVisiblityStateChanging += this.RibbonBarElement_ItemVisiblityStateChanging;
        }

        private void RibbonBarElement_ItemVisiblityStateChanging(object sender, ItemVisiblityStateChangingEventArgs args)
        {
            if (args.NextVisibilityState == ChunkVisibilityState.NoText)
            {
                args.Cancel = true;
            }
        }

Please refer to the attached sample project and follow the steps from the gif file. 

Shrink the ribbon to create sub groups for expanding. Then, maximize the form. You will notice that the groups are still collapsed although there is so much space.
