It appears that this scenario is not handled properly in our exporter. Consider the case where you have two templates that use view definition. 

The view definition from the second template is not exported at all.

The last row is not detected in the Inspect Tool and in the Accessibility Insights for Windows tool.

In this case, the control is populated with business objects. The AutoCompleteDisplayMember property of the control point to a property of this object. This property can have a similar value to more than one item from the source collection. When we try to select a specific item using the Text property, the control will select the first occurrence of the value that is found in the collection. This behavior can be improved to allow to select specific item from the collection with duplicate values.

 this.toolWindow1.TabStrip.MinimumSize = new Size(200,200)

To reproduce:

        ThemeResolutionService.ApplicationThemeName = "Windows11"

        Dim UserGroup As New DescriptionTextListDataItem
        With UserGroup
            .Text = "Admins"
            '.Font = New Font("Microsoft Sans Serif", 9.75, FontStyle.Bold)
            .DescriptionText = "System Administrations Group"
        End With
        Me.RadListControl1.Items.Add(UserGroup)
        Me.RadListControl1.ItemHeight = 50

Actual result:

Expected result:

Use attached to reproduce:
- Disable and then enable the RadSateTimePicker
- You will notice that even the checkbox is unchecked the control is enabled. 

Workaround:

radDateTimePicker1.Enabled =true;
if (!radDateTimePicker1.DateTimePickerElement.Checked)
{
    radDateTimePicker1.DateTimePickerElement.TextBoxElement.TextBoxItem.HostedControl.Enabled = false;
}

To reproduce:
            this.radDropDownList1.DropDownListElement.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
            this.radDropDownList1.DropDownListElement.AutoCompleteAppend.LimitToList = true;
            this.radDropDownList1.DataSource = new List<string>() { "Test1", "Test2" };

Copy "Test2" and right click over the textbox. The second item is selected. However, if you press Ctrl+V instead of using the Paste option in the context menu, nothing happens.

Workaround:

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        RadDropDownList1.DropDownListElement.AutoCompleteMode = AutoCompleteMode.SuggestAppend
        RadDropDownList1.DropDownListElement.AutoCompleteAppend.LimitToList = True
        RadDropDownList1.DataSource = {"Test1", "Test2"}
        
        Me.RadDropDownList1.DropDownListElement.AutoCompleteAppend = New CustomAutoCompleteAppendHelper(Me.RadDropDownList1.DropDownListElement)
    End Sub 

    Public Class CustomAutoCompleteAppendHelper
    Inherits AutoCompleteAppendHelper
        Public Sub New(owner As RadDropDownListElement)
            MyBase.New(owner)

        End Sub

        Public Overrides Sub AutoComplete(e As KeyPressEventArgs)
            If Control.ModifierKeys = Keys.Control AndAlso Asc(e.KeyChar) = 22 Then
                Me.AutoComplete(e, False)
            Else
                Me.AutoComplete(e, Me.LimitToList)
            End If 
        End Sub
    End Class

To reproduce:
- Add some rows to a grid.
- Sort the rows.
- Delete a row.
- The current row is not the next row.

Workaround:
Dim t As Test = RadGridView1.CurrentRow.DataBoundItem
Dim index As Integer = Me.RadGridView1.ChildRows.IndexOf(Me.RadGridView1.CurrentRow)
datasource.Remove(t)
Me.RadGridView1.CurrentRow = Me.RadGridView1.ChildRows(index)

How to reproduce: set a size in the designer, when the form loads its size will not be the same as the one set

Workaround: set the size in the Load event of the ribbon form

private void Form_Shown(object sender, EventArgs e)
{
	this.Size = new Size(600, 600);
}

To reproduce: 
1. Use the following code snippet:
public class ViewModel:INotifyPropertyChanged
{
    public ViewModel()
    {
    }

    private bool _isShown;

    public bool IsShown
    {
        get
        {
            return this._isShown;
        }
        set
        {
            this._isShown = value;
            OnPropertyChanged("IsShown");
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;

    protected void OnPropertyChanged(string propertyName)
    {
        PropertyChangedEventHandler handler = PropertyChanged;
        if (handler != null)
            handler(this, new PropertyChangedEventArgs(propertyName));
    }
}

2. Add a MS Panel and a RadPanel to the form.
3. Add Panel.DataBindings at design time for its Visible property to the ViewModel.IsShown property.
4. When you run the application, the MS Panel is not visible. However, if you remove the RadPanel it is shown. Please refer to the attached sample video illustrtaing better the performed steps.

Run the attached project and select a new value from the drop down for RadTimePicker:

Workaround:

        Timer t = new Timer();

        private void RadTimePicker1_ValueChanged(object sender, EventArgs e)
        {
            if (radTimePicker1.Value == null) return;

            var timeval = ((DateTime)radTimePicker1.Value).TimeOfDay;

            if (timeval == TimeSpan.Zero)
            {
                t = new Timer();
                t.Interval = 500;
                t.Tick += T_Tick; t.Start();
            }
        }

        private void T_Tick(object sender, EventArgs e)
        {
            t.Stop();
            this.radTimePicker1.ValueChanged -= RadTimePicker1_ValueChanged;
            this.radTimePicker1.Value = null;
            this.radTimePicker1.ValueChanged += RadTimePicker1_ValueChanged;
        }

To reproduce:
- Add some full pages to the editor. 
- Remove all margin from the print settings and document settings.
- PrintPreview the document.
- Seth the print preview dialog zoom to 100% and compare the documents.
- You will notice that the print document's content is smaller.

Please refer to the attached screenshot and sample project.

Workaround: call the RadForm.EndInit method before showing the form.

Follow the steps:

1.Group by Description.

2. Expand the groups

3. Sort by Id

4. Try expanding the hierarchical level. You will notice that some of the rows disappear.

Please refer to the attached gif file illustrating the steps for replicating the issue.

Use the code snippet:

    Sub New()

        InitializeComponent()
        Me.RadSpinEditor1.EnableNullValueInput = True
        Me.RadSpinEditor1.NullableValue = Nothing

        Console.WriteLine("Value " & Me.RadSpinEditor1.Value & " END")
        Console.WriteLine("NullableValue " & Me.RadSpinEditor1.NullableValue & " END")
    End Sub

    Private Sub RadSpinEditor1_NullableValueChanged(sender As Object, e As EventArgs) Handles RadSpinEditor1.NullableValueChanged
        Console.WriteLine("NullableValueChanged " & Me.RadSpinEditor1.NullableValue & " END")
    End Sub

Follow the steps:

1. Run the project with the above code and enter 0 in the spin editor. Navigate to the next control. You will notice that the NullableValueChanged event doesn't get fired.

2. Focus the spin editor again and enter 5. Navigate to the next control. The NullableValueChanged event is fired as expected.

3. Focus again the spin editor, select the text and press Del. Navigate to the next control. The NullableValueChanged event is fired again as expected.

4. Focus again the spin editor and enter 0. Navigate to the next control. You will notice that the NullableValueChanged event is fired.

5. Focus again the spin editor, select the text and press Del. Navigate to the next control. The NullableValueChanged event is fired again as expected.

6. Focus again the spin editor and enter 0. Navigate to the next control. You will notice that the NullableValueChanged event is NOT fired in this case.
