This behavior can be observed in the Office2010 theme. In the following image, the button's width in RadCalculatorDropDown and RadSpinEditor is less by 1 px compared to the buttons in the other editor controls.

Sample code to reproduce the case: 

            if (int.TryParse(txtCount.Text, out int count))
            {
                string textToSet=new string('A', count)+"END";
                txtSample.Text = textToSet;

                this.radTextBox1.MaxLength = textToSet.Length;
               
                this.Text = txtSample.Text.Length.ToString();
               
            }

You need to press Tab twice to move to the next control when in popup editor.

Use attached to reproduce. 

Set the format:

dateTimePicker1.Format = DateTimePickerFormat.Custom;
dateTimePicker1.CustomFormat = "dd/MM/yyyy";

Enter 18 in the yaer part, the year should be set to 2018, the year should be cleared when starting to type as well.

Use the following code snippet:

            this.radMaskedEditBox1.Mask = "99/99/99/99/99/99";
            this.radMaskedEditBox1.MaskType = Telerik.WinControls.UI.MaskType.Standard;
            this.radMaskedEditBox1.PromptChar = ' ';
            ((StandartMaskTextBoxProvider)this.radMaskedEditBox1.MaskedEditBoxElement.Provider).TryGetStandardProvider().InsertKeyMode = InsertKeyMode.Overwrite;

When the cursor is just before the last "/", if you enter a number, then the cursor does not move after this last "/". Then entering another digit overwrites the last digit typed.

Hello,

I have noticed a bug in the Autocompletebox.

When the Autocompletebox.Multiline is enabled and setting the text to an item with multiple delimiters where the items are shown on multiple lines (see image).

When clicking on one of the items in line 2 or 3, the value e.selectionstart returned on the Selectionchanged-event has a wrong value.

On line 2 the e.selectionstart is 1 too much

Imports Telerik.WinControls.UI

Public Class RadForm1
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim str As String = "Item 1;Item 2;Item 3;Item 4;Item 5;Item 6;Item 7;Item 8;Item 9;Item 10;"
        RadAutoCompleteBox1.Multiline = True
        RadAutoCompleteBox1.Text = str

    End Sub

    Private Sub RadAutoCompleteBox1_SelectionChanged(sender As Object, e As SelectionChangedEventArgs) Handles RadAutoCompleteBox1.SelectionChanged
        Dim SelectedItem As String = RadAutoCompleteBox1.Text.Substring(e.SelectionStart, e.SelectionLength)
        Debug.Print(SelectedItem)
    End Sub
End Class

Use the following code to setup RadMaskedEditBox. When you start typing you will notice that the ValueChanged event is fired but the ValueChanging is not: 

            this.radMaskedEditBox1.MaskType = MaskType.Standard;
            this.radMaskedEditBox1.Mask = "AAAA";

            this.radMaskedEditBox1.ValueChanged += radMaskedEditBox1_ValueChanged;
            this.radMaskedEditBox1.ValueChanging += radMaskedEditBox1_ValueChanging;

        private void radMaskedEditBox1_ValueChanging(object sender, CancelEventArgs e)
        {
        }

        private void radMaskedEditBox1_ValueChanged(object sender, EventArgs e)
        {
        }

Please refer to the following code snippet:

After running the application and try to enter "123". You will notice that you can enter only "1".

To reproduce:

- Set SutoSize to false and resize the control vertically.

Workaround:

radMaskedEditBox1.MaskedEditBoxElement.StretchVertically = true;

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.

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

The issue can be reproduced with custom regional settings and the following mask: dd/MM/yyyy

Workaround: if possible please reset the DateTime region settings

Set the property to the hosted textbox instead: 
Me.RadSpinEditor1..SpinElement.TextBoxItem.TabStop = False

or create a custom control: 
Public Class MyRadSpinEditor
    Inherits RadSpinEditor

    <DefaultValue(True)>
    Public Overloads Property TabStop As Boolean
        Get

            If Me.SpinElement.TextBoxItem IsNot Nothing Then
                Return Me.SpinElement.TextBoxItem.TabStop
            End If

            Return MyBase.TabStop
        End Get
        Set(ByVal value As Boolean)

            If Me.SpinElement.TextBoxItem IsNot Nothing Then
                MyBase.TabStop = False
                Me.SpinElement.TextBoxItem.TabStop = value
                Return
            End If

            MyBase.TabStop = value
        End Set
    End Property
End Class

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.

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

Workaround: use RadTextBoxControl.

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: handle the following event and start typing in the editable part. You will notice that the TextChanged event is not fired:
Me.RadPopupEditor1.DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDown
AddHandler Me.RadPopupEditor1.TextChanged, AddressOf RadPopupEditor1_TextChanged

Workaround: handle the RadPopupEditor.TextBoxElement.TextChanged event instead.

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));
}

How to reproduce:
Set the AutoSpellCheckControl property of the spell checker and use it in a DPI-aware application on a system with an increased scaling. Type an incorrect and notice that the context menu will not be scaled.

Workaround: 
Public Class RadForm1
    Sub New()

        InitializeComponent()

        'TextBox
        Me.RadSpellChecker1.AutoSpellCheckControl = Me.TextBox1
        Dim dpi = NativeMethods.GetSystemDpi()
        Dim checker = TryCast(Me.RadSpellChecker1.GetControlSpellChecker(GetType(TextBox)), TextBoxSpellChecker)
        checker.DropDownMenu.PopupElement.DpiScaleChanged(New SizeF(dpi.X / 96, dpi.Y / 96))

        'RadTextBox
        'Me.RadSpellChecker1.AutoSpellCheckControl = Me.RadTextBox1
        'Dim dpi = NativeMethods.GetSystemDpi()
        'Dim checker = TryCast(Me.RadSpellChecker1.GetControlSpellChecker(GetType(RadTextBox)), TextBoxSpellChecker)
        'checker.DropDownMenu.PopupElement.DpiScaleChanged(New SizeF(dpi.X / 96, dpi.Y / 96))
    End Sub
End Class
