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

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. 

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

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.

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.

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,

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

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 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.

1. Enable Backstage view mode

radRibbonBar1.ApplicationMenuStyle = Telerik.WinControls.UI.ApplicationMenuStyle.BackstageView;

2. Add BackstageButtonItem and BackstageTabItem to the Application Menu.

3. Run the program and run the accessibility tool "inspect.exe"

4. Select MSAA in "inspect.exe" and hover over a Backstage item.

As you can see in the attached screenshot BackstageButtonItems and BackstageTabItems are not accessible by inspect.exe.

To reproduce:

1. Add a form with a RadRibbonBar and add some tabs

2. Create a second form that inherits the first one

3. Open the second form at design time and add a few items to the application menu.

Expected: either the applied changes in the derived form should be serialized properly or the ribbon in the derived form should be locked for such changed.

Actual: even though the menu items are added in the designer and you can see them, after restarting the designer, they are not shown in the application menu anymore. You can see that they are still available in the Designer.cs but they are not added to the application menu. The same behavior is observed if you add tabs and groups with different elements.

The caption text of the RibbonBarGroups disappears when switching themes runtime. The important part is that this behavior is observable when switching from the Office2010Blue theme to other themes. In this specific theme, the FillPrimitive holding the TextPrimitive (caption text) has the PositionOffset property set to 0,-1. This minus one pixel is messing up the layout during theme change.

What can be done as a workaround is to reset this property for every group. When the Office2010Blue theme is applied run this code:

private void radButton1_Click(object sender, EventArgs e)
{
    Office2010BlueTheme theme = new Office2010BlueTheme();
    ThemeResolutionService.ApplicationThemeName = "Office2010Blue";
    foreach (var item in this.ribbonTab1.Items)
    {
        if (item is RadRibbonBarGroup)
        {
            var group = item as RadRibbonBarGroup;
            group.Children[1].Children[0].PositionOffset = new SizeF(0, 0);
        }
    }
}

In this case, the group is in collapsed mode. When we open its drop-down button to see the elements inside and afterward expand the form to see the whole group, the theme of the group is reset. Moving the mouse over the group will reset the theme.

The theme component is added to the form:

Here is the code:

Public Class RadRibbonForm1
    Sub New()

        InitializeComponent()

        Me.AllowAero = False

    End Sub

    Private Sub RadButtonElement1_Click(sender As Object, e As EventArgs) Handles RadButtonElement1.Click
        ThemeResolutionService.ApplicationThemeName = "Office2010Blue"
    End Sub
End Class
