The AccessibleName property is not respected by the Windows Narrator.

Other controls that have the same behavior:

• RadMaskedEditBox

Use the following code snippet:

    Sub New() 
        InitializeComponent()
        Me.RadCheckedDropDownList1.ShowCheckAllItems = True
        Me.RadCheckedDropDownList1.AutoSizeItems = True
        For x = 1 To 20
            Dim i As New DescriptionTextCheckedListDataItem
            i.Value = x
            i.Text = x.ToString()
            i.DescriptionText = "abc def ghijkl mnop abc def ghijkl mnop" & x
            Me.RadCheckedDropDownList1.Items.Add(i)
        Next 
    End Sub

Open the popup, scroll to the bottom and then back to the top.

Expected: The CheckAllItem is visible

Actual: The CheckAllItem is hidden

The issue exists with RadMenuItem as well!

Workaround:

public class CustomCommandBarButton : CommandBarButton
{
    protected override void OnClick(EventArgs e)
    {
        MouseEventArgs args = e as MouseEventArgs;
        if (args.Button == System.Windows.Forms.MouseButtons.Left)
        {
            base.OnClick(e);
        }
    }

    protected override Type ThemeEffectiveType     
    { 
        get    
        { 
            return typeof(CommandBarButton);     
        }
    }
}

Please run the attached sample project and navigate with the left/right arrows as it is demonstrated in the gif file.

This width is 6px by default and it doesn't offer convenient API for customizing it:

Workaround:

public class CustomRadDropDownList : RadDropDownList
{
    protected override RadDropDownListElement CreateDropDownListElement()
    {
        return new CustomRadDropDownListElement();
    }

    public override string ThemeClassName  
    { 
        get 
        { 
            return typeof(RadDropDownList).FullName;  
        }
    }
}

public class CustomRadDropDownListElement : RadDropDownListElement
{
    protected override RadDropDownListArrowButtonElement CreateArrowButtonElement()
    {
        return new CustomRadDropDownListArrowButtonElement();
    }

    protected override Type ThemeEffectiveType     
    { 
        get    
        { 
            return typeof(RadDropDownListElement);     
        }
    }
}

public class CustomRadDropDownListArrowButtonElement : RadDropDownListArrowButtonElement
{
    protected override Type ThemeEffectiveType     
    { 
        get    
        { 
            return typeof(RadDropDownListArrowButtonElement);     
        }
    }
    
    protected override void OnClick(EventArgs e)
    {
        MouseEventArgs args = e as MouseEventArgs;
        if (args.Button == System.Windows.Forms.MouseButtons.Left)
        {
            base.OnClick(e);
        }
    }
}

In the Visual Theme Builder (fresh installed Telerik UI for WinForms) you'll get an error because the directory "VbsRecoveryData" seems to be missing. Creating the directory before "package.Compress(path)" fixes this for me.

In this specific scenario, we have a menu with 2 menu items: &File and &Open. The mnemonic sign is set to the F and O letters. In the form, we have a TextBox control which is currently focused. The next step is to press the Alt key while the TextBox is focused. Pressing some other letter, D for example, the letter will be typed in the TextBox. This letter does not exist as a mnemonic, and the RadMenu will ignore it. The RadMenu remains in active mnemonic state.

Expected behavior: Using none mnemonic letter should not be accepted by any other control until this state is closed in the RadMenu.

Hello, 

we are trying to use RadPropertyGrid to show the properties of some objects listed in a RadGrdiView. 

We use ExpandableObject to expand our custom property, but we have some problems when we try to show the properties of multiple selected items, when the values of the attribute of the property are not the same in all the selected objects. We tried to use PropertyGrid of Winform and we don't have this problem. 

Thank you.

To reproduce:

private void Form1_Load(object sender, EventArgs e)
        {
            this.categoriesTableAdapter.Fill(this.nwindDataSet.Categories);

            this.radMultiColumnComboBox1.DataSource = this.categoriesBindingSource;
            this.radMultiColumnComboBox1.DisplayMember = "CategoryName";
            this.radMultiColumnComboBox1.ValueMember = "CategoryID";

            this.radMultiColumnComboBox1.EditorControl.EnableFiltering = true;
            this.radMultiColumnComboBox1.EditorControl.ShowHeaderCellButtons = true;
        }

Workaround:

 public Form1()
 {
     InitializeComponent();
     this.radMultiColumnComboBox1.MultiColumnComboBoxElement.PopupClosing += MultiColumnComboBoxElement_PopupClosing;
     this.radMultiColumnComboBox1.EditorControl.FilterPopupInitialized += EditorControl_FilterPopupInitialized;
 }

 private void EditorControl_FilterPopupInitialized(object sender, FilterPopupInitializedEventArgs e)
 {
     RadListFilterPopup filterPopup = e.FilterPopup as RadListFilterPopup;
     if (filterPopup != null)
     {
         filterPopup.PopupOpened -= filterPopup_PopupOpened;
         filterPopup.PopupOpened += filterPopup_PopupOpened;
         filterPopup.PopupClosed -= filterPopup_PopupClosed;
         filterPopup.PopupClosed += filterPopup_PopupClosed;
     }
 }

 bool shouldCancel = false;

 private void filterPopup_PopupClosed(object sender, RadPopupClosedEventArgs args)
 {
     shouldCancel = false;
 }

 private void filterPopup_PopupOpened(object sender, EventArgs args)
 {
     shouldCancel = true;
 }

 private void MultiColumnComboBoxElement_PopupClosing(object sender, RadPopupClosingEventArgs args)
 {
     args.Cancel = shouldCancel;
 }

On the first click, the ContextMenu (or commandbar menu) will be shown with scrollbars. If I dismiss and immediately click again, the scrollbars are now gone. Although it is not consistent, for some menu items, the scrollbars are always shown.

In the following scenario, the item's text in the drop-down list shows different text from the selected item.
