RadDataLayout.LayoutControl has Text property and it is not relevant to show RadMarkupEditor when changing the text.

How to reproduce: 
radDateTimePicker1.DateTimePickerElement.ShowTimePicker = true;
radDateTimePicker1.Format = DateTimePickerFormat.Custom;
radDateTimePicker1.DateTimePickerElement.CalendarSize = new Size(330, 250);
radDateTimePicker1.ReadOnly = true;

Workaround: 
this.radDateTimePicker1.DateTimePickerElement.ShowTimePicker = true;
this.radDateTimePicker1.Format = DateTimePickerFormat.Custom;
this.radDateTimePicker1.DateTimePickerElement.CalendarSize = new Size(330, 250);
this.radDateTimePicker1.ReadOnly = true;

RadDateTimePickerCalendar calendarBehavior = this.radDateTimePicker1.DateTimePickerElement.GetCurrentBehavior() as RadDateTimePickerCalendar;
calendarBehavior.TimePicker.TimePickerElement.ReadOnly = true;

To reproduce: please refer to the attached sample screenshots and project.

Note: this issue is relevant for RadDropDownList as well.

Workaround:             
            this.radDropDownList2.DropDownListElement.TextBox.TextBoxItem.Multiline = true;
            this.radDropDownList2.DropDownListElement.TextBox.TextBoxItem.MinSize  = new Size(30, 15); 

How to reproduce: check the attached project and video

Workaround: set a minimum size to the control
 public partial class RadForm1 : RadForm
 {
     public RadForm1()
     {
         InitializeComponent();

         this.radTextBox1.MinimumSize = new Size(0, 20);
     }
 }

How to reproduce: add a spellchecker to the form and configure it to spellcheck a multi line text box with a very long text.

Workaround: use RadTextBoxControl

To reproduce:

            this.radTextBox1.NullText = "text";
            this.radTextBox1.TextBoxElement.TextBoxItem.NullTextColor = Color.Red;

Workaround:  this.radTextBox1.TextBoxElement.NullTextColor = Color.Red;

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:

        Me.RadDateTimePicker1.Format = DateTimePickerFormat.Custom
        Me.RadDateTimePicker1.CustomFormat = "MM/dd/yyyy"

        Dim provider As MaskDateTimeProvider = TryCast(Me.RadDateTimePicker1.DateTimePickerElement.TextBoxElement.Provider, MaskDateTimeProvider)
        provider.AutoSelectNextPart = True

 If you type in 01/01/50, RadDateTimePicker displays 01/01/1950 which is correct. If you type in 01/01/2050, the system is again changing the century and display 01/01/1950 which is incorrect. 

Workaround: use a custom mask provider to customize how the autocompletion work:
    Public Class CustomMaskDateTimeProvider
        Inherits Telerik.WinControls.UI.MaskDateTimeProvider
        Public Sub New(mask As String, culture As CultureInfo, owner As RadMaskedEditBoxElement)
            MyBase.New(mask, culture, owner)

        End Sub

        Protected Overrides Function HandleKeyPress(part As MaskPart, e As KeyPressEventArgs) As Boolean
            Dim value As Integer = 0
            If Not Integer.TryParse(e.KeyChar.ToString(), value) Then
                Return True
            End If

            Dim stringValue As String = String.Empty
            If part.type = PartTypes.MiliSeconds Then
                Dim newValue As Integer = CInt((part.value / Math.Pow(10, (3 - part.len)))) * 10 + value
                part.value = newValue Mod CInt(Math.Pow(10, part.len))
            Else
                stringValue = part.value.ToString()
                If stringValue.Length = part.len AndAlso stringValue.Length >= part.maskPart.Length Then
                    stringValue = stringValue.Substring(1)
                End If

                If Me.AutoCompleteYear AndAlso stringValue.Length = 1 Then
                    stringValue = String.Empty
                End If

                part.value = Integer.Parse(stringValue & e.KeyChar)
            End If

            If part.type = PartTypes.Year AndAlso part.maskPart.Length = 2 Then
                Dim len As Integer = part.value.ToString().Length
                part.value = Integer.Parse(String.Format("{0}{1}", DateTime.Now.Year.ToString().Substring(0, 2), part.value.ToString().Substring(len - 2, 2)))
            End If

            If Me.AutoCompleteYear AndAlso part.type = PartTypes.Year Then
                Dim len As Integer = part.value.ToString().Length
                If len >= 2 Then
                    part.value = Integer.Parse(part.value.ToString().Substring(len - 2, 2))
                End If

                'If part.value >= 50 AndAlso part.value <= 99 Then
                '    part.value += 1900
                'ElseIf part.value >= 500 AndAlso part.value <= 999 Then
                '    part.value += 1000
                'ElseIf part.value < 50 OrElse (part.value > 99 AndAlso part.value < 500) Then
                part.value += 2000
                ' End If
            End If

            If part.value > part.max OrElse part.value < part.min Then
                part.value = value
            End If

            Return True
        End Function
         
    End Class

  Me.RadDateTimePicker1.Format = DateTimePickerFormat.Custom
        Me.RadDateTimePicker1.CustomFormat = "MM/dd/yyyy"

        Me.RadDateTimePicker1.DateTimePickerElement.TextBoxElement.Provider = New CustomMaskDateTimeProvider(Me.RadDateTimePicker1.DateTimePickerElement.TextBoxElement.Mask, Me.RadDateTimePicker1.Culture, Me.RadDateTimePicker1.DateTimePickerElement.TextBoxElement)

        Dim provider As MaskDateTimeProvider = TryCast(Me.RadDateTimePicker1.DateTimePickerElement.TextBoxElement.Provider, MaskDateTimeProvider)
        provider.MaxDate = Me.RadDateTimePicker1.DateTimePickerElement.MaxDate
        provider.AutoSelectNextPart = True
        provider.AutoCompleteYear = True

Thus, the year always be 2000+.

Use attached to reproduce.
- Open the dialog multiple times.

https://msdn.microsoft.com/en-us/library/system.windows.forms.maskedtextbox.maskcompleted(v=vs.110).aspx

To reproduce:       
 Me.RadDateTimePicker2.Format = DateTimePickerFormat.Custom
 Me.RadDateTimePicker2.CustomFormat = "hh:mm tt"

Select the hours part with the mouse, the selection is affected correctly. Select the minutes part, the selection is affected correctly. Select the AM/PM part, the selection is again affected correctly. Now, try to select again the minutes part. You will notice that the cursor is affected correctly but the selection is missing. Once you select the AM/PM part then the selection is not updated properly with the mouse anymore.

Workaround:

Me.RadDateTimePicker1.DateTimePickerElement.TextBoxElement.Provider = New CustomMaskDateTimeProvider(Me.RadDateTimePicker2.DateTimePickerElement.TextBoxElement.Mask, Me.RadDateTimePicker2.Culture, Me.RadDateTimePicker2.DateTimePickerElement.TextBoxElement)

                If currentSelection >= part.offset AndAlso currentSelection <= part.offset + part.len AndAlso Not part.[readOnly] AndAlso part.type <> PartTypes.Character Then
                    Me.TextBoxItem.SelectionStart = Me.List(i).offset
                    Me.TextBoxItem.SelectionLength = Me.List(i).len
                    Me.SelectedItemIndex = i

To reproduce: 

            this.radBrowseEditor1.Value = @"D:\Projects";
            this.radBrowseEditor1.ReadOnly = false; 
            this.radBrowseEditor1.BrowseElement.ShowClearButton = true;

You will notice that the clear button is not shown.

Workaround:

            LightVisualButtonElement btn = new LightVisualButtonElement();
            btn.Text = "X";
            btn.Click += btn_Click;

            this.radBrowseEditor1.BrowseElement.BrowseButton.Parent.Children.Add(btn);


        private void btn_Click(object sender, EventArgs e)
        {
            this.radBrowseEditor1.Value = null;
        }

To reproduce:
radPopupEditor1.PopupForm.VerticalPopupAlignment = VerticalPopupAlignment.TopToBottom;

Workaround:
private void RadPopupEditor1_PopupOpening(object sender, CancelEventArgs e)
{
    var args = e as RadPopupOpeningEventArgs;
    args.CustomLocation = new Point(args.CustomLocation.X, args.CustomLocation.Y - (radPopupEditor1.Height + radPopupEditor1.PopupForm.Height));
}

To reproduce: set the ThemeName property before setting the RadDateTimePickerCalendarShowTimePicker property to true.
    Private Sub RadForm1_Load(sender As Object, e As EventArgs) Handles MyBase.Load

        Me.RadDateTimePicker1.ThemeName = "TelerikMetro"
        TryCast(Me.RadDateTimePicker1.DateTimePickerElement.CurrentBehavior, RadDateTimePickerCalendar).ShowTimePicker = True
    End Sub

Workaround:

    Private Sub RadForm1_Load(sender As Object, e As EventArgs) Handles MyBase.Load

        TryCast(Me.RadDateTimePicker1.DateTimePickerElement.CurrentBehavior, RadDateTimePickerCalendar).ShowTimePicker = True
        Me.RadDateTimePicker1.ThemeName = "TelerikMetro"
    End Sub

To reproduce: please refer to the attached sample project and follow the steps from the provided gif file.

Workaround: use RadTextBoxControl.

To reproduce: follow the steps illustrated in the gif file.

1. Set Autosize = false.

2. Resize the control by increasing its height.

3. Change Multiline property to true.

4. Change Multiline property to false.

5. Autosize property is reset by doing 4. So set Autosize to false again.

Workaround: Use only the Multiline property.

Hi,

We have an issue with the RadMaskedEditBox control using an f0 mask.

The issue we have is..

When entering a number i.e. 123456 followed by pressing the backspace key, results in the number showing as 123450

We would expect this to show as 12345 so assume this is either a bug or requires up to add additional configuration when using f0.

I have included an example which demonstrates this

Many thanks

Steps:

1) Add a textbox to a form. Set tabindex set to 0.

2) Add a RadMaskedEditBox with tabindex set to 1, and add the code listed below.

        public Form1()
        {
            InitializeComponent();

            this.radMaskedEditBox1.MaskType = MaskType.Standard;
            this.radMaskedEditBox1.Mask = "000000";
            this.radMaskedEditBox1.PromptChar = '#';
            this.radMaskedEditBox1.SelectionStart = 0;
            this.radMaskedEditBox1.SelectionLength = 0;
            
            this.radMaskedEditBox1.Enter += radMaskedEditBox1_Enter;
            this.radMaskedEditBox1.Click += radMaskedEditBox1_Click;
            this.radMaskedEditBox1.MaskedEditBoxElement.TextBoxItem.Click += TextBoxItem_Click;
        }

        void radMaskedEditBox1_Enter(object sender, EventArgs e)
        {
            this.radMaskedEditBox1.SelectionStart = 0;
        }

        void TextBoxItem_Click(object sender, EventArgs e)
        {
            this.radMaskedEditBox1.SelectionStart = 0;
        }

        void radMaskedEditBox1_Click(object sender, EventArgs e)
        {
            
        }

3) Add breakpoints to all 3 RadMaskedEditBox events.

4) Run the app. Press tab key. (Enter event works as expected for the MaskedEditBox class).

5) Close and re-run app. Click the end of the MaskedEditBox. Click event is not invoked by the MaskedEditBox class as expected. 

Expected Result:

Since this control really only has 1 primary subcontrol (a fancy textbox). Event subscriptions to Click should subscribe to MaskedEditBoxElement.TextBoxItem.Click the += operator...

Should be fixed for MouseUp/Down and the all the other related key and mouse events.

Actual Result:

Subscriptions to Enter work on the MaskedEditBox class, but only subscriptions to MaskedEditBoxElement.TextBoxItem.Click work for Click events. This is highly confusing to the programmer whom is used to subscribing the standard Click event of a given control, and makes for unnecessarily complicated code and knowledge of the internal Element structure to make it work as expect like any other control.

Feature request:

It would be nice if there was also a "SelectionStart_MouseClick" property that works similar to SelectionStart but for Click events.

Also a EnableSelectionStart_MouseClick property with a default of false to maintain existing control behavior.

This allows the user to override the default cursor start position for Mouse Clicks. In the case above, the user cannot enter numbers unless they specifically click the start of the Mask; users find that confusing... 

The purpose of the above code is to be able to set the cursor start position "on-click", rather than only on Enter, which the existing SelectionStart property doesn't achieve.

Then we programmers could just set the properties and be done with it, and any subscriptions to the Click event would work as expected ->

        public Form1()
        {
            InitializeComponent();

            var customControl = new RadMaskedEditBoxV2()
            {
                MaskType = MaskType.Standard,
                Mask = "000000",
                PromptChar = '#',
                SelectionLength = 0,
                SelectionStart = 0,
                EnableSelectionStart_MouseClick = true,
                SelectionLength_MouseClick = 6,
                SelectionStart_MouseClick = 0
            };

            this.Controls.Add(customControl);
        }
 
 
 

        public class RadMaskedEditBoxV2 : Telerik.WinControls.UI.RadMaskedEditBox
        {
            public RadMaskedEditBoxV2()
                : base()
            {
                this.EnableSelectionStart_MouseClick = false;
                this.MaskedEditBoxElement.TextBoxItem.Click += SelectionStartMouseClick_OnClick;
            }

            public new event EventHandler Click
            {
                add
                {
                    base.MaskedEditBoxElement.TextBoxItem.Click += value;
                }
                remove
                {
                    base.MaskedEditBoxElement.TextBoxItem.Click -= value;
                }
            }

            protected virtual void SelectionStartMouseClick_OnClick(object sender, EventArgs e)
            {
                if (EnableSelectionStart_MouseClick)
                {
                    this.SelectionStart = SelectionStart_MouseClick;
                    this.SelectionLength = SelectionLength_MouseClick;
                }
            }

            public int SelectionStart_MouseClick { get; set; }
            public int SelectionLength_MouseClick { get; set; }
            public bool EnableSelectionStart_MouseClick { get; set; }
        }

It would also allow the programmer to set the Enter and Click SelectionLengths separately.

Regards,

-Shawn.

To reproduce:

- Set SutoSize to false and resize the control vertically.

Workaround:

radMaskedEditBox1.MaskedEditBoxElement.StretchVertically = true;
