When Windows aero effects are enabled and the form width is being decreased, the title bar text appears over the title bar buttons and further more when continuing reducing the width of the form the buttons disappear and a small black rectangle is shown instead.

void Form1_Resize(object sender, System.EventArgs e)
{
    if (this.WindowState == FormWindowState.Maximized)
    {
        this.RibbonBar.RibbonBarElement.IconPrimitive.Padding = new Padding(5, 5, 0, 0);
    }
    else
    {
        this.RibbonBar.RibbonBarElement.IconPrimitive.Padding = Padding.Empty;
    }
}

Use the attached project to reproduce.

Workaround:
private void RadForm1_SizeChanged(object sender, EventArgs e)
{
    if (this.WindowState == FormWindowState.Normal)
    {
        this.SizeChanged -= RadForm1_SizeChanged;
        this.Size = new Size(this.Size.Width + 1, this.Size.Height + 1);
        this.Size = new Size(this.Size.Width - 1, this.Size.Height - 1);

        this.SizeChanged += RadForm1_SizeChanged;
    }
}

To reproduce: please run the attached sample project and follow the steps from the gif file.

Workaround: close the popup before showing the message or the dialog:

        {
              if (!radRibbonBar1.Expanded)
            {
                this.radRibbonBar1.RibbonBarElement.Popup.ClosePopup(Telerik.WinControls.UI.RadPopupCloseReason.Mouse);
            }
            RadMessageBox.Show("Test");

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;
            }
        }

If I left-click on one of tab header, the related tab expand itself showing all the contained items.
But, if I expand the tab using the mouse right button, the tab expand itself but it appears blank!

Workaround:

private void radRibbonBar1_MouseDown(object sender, MouseEventArgs e)
{
    RibbonTab tab = this.radRibbonBar1.ElementTree.GetElementAtPoint(e.Location) as RibbonTab;
    if (tab!=null && e.Button== System.Windows.Forms.MouseButtons.Right)
    {
        tab.IsSelected = true;
    }
}

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

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.

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

Setting the ShowBorder property design time, will not serialize its value in the designer. Changing the form size, for example, will remove the setter of this property from the designer.cs file.
