In this scenario, the Browsable(false) attribute is set to both properties which are used to create the self-referencing hierarchy. When the columns are predefined, running that application will freeze as the RadGridView could not correctly get the parent row. If the columns are auto-generated, this behavior is not observed. 

This is not exactly a real solution as setting the Browsable(false) attribute will remove the properties from the source. However, the control should not freeze the application.

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.

 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.
