When the ReadOnly property of RadTimePicker is true, setting the Value property in code does not cause any effect on the UI of RadTimePicker.

The TabStop property set via the property builder of VS should be able to set the determine the tabbing behavior of RadTextBox and more specifically, the behavior of its inner TextBoxItem. Right now, the developer has to use a line of code to determine this behavior:
this.radTextBox1.TextBoxElement.TextBoxItem.TabStop = false;
while the TabStop of RadTextBox is always false, so that the focused can be always transferred to the inner TextBoxItem.

Currently, you cannot enter the date in RadDateTimePicker by typing it in the textbox area.

If the size of the text and icons on the screen is set to larger and the font of the text is set to 12 pixels. Letters that have tails below (such as: g, j, y) are not shown properly inside the text box. 

Workaround:

As a workaround one can set the minimum height of the text box to be as the height of the text and allow multi lines.

int textHeight = TextRenderer.MeasureText(this.radTextBox1.Text, this.radTextBox1.Font).Height;this.radTextBox1.TextBoxElement.TextBoxItem.MinSize = new Size(0, textHeight);this.radTextBox1.TextBoxElement.TextBoxItem.InvalidateMeasure();this.radTextBox1.TextBoxElement.TextBoxItem.UpdateLayout();this.radTextBox1.Multiline = true;

Extend the functionality of the RadMaskedEditBox to support continuous user input, i.e. no navigation keys are required to move the cursor between the separate editable parts of the current mask.

Put couple text boxes on a form in design time and you will have to press Shift+TAB twice to get the focus to the previously focused text box.

Currently, this can be achieve with this code:
  TextInfo textInfo = new CultureInfo("en-US", false).TextInfo;
        bool updating = false;
        void radTextBox1_TextChanging(object sender, TextChangingEventArgs e)
        {
            if (!updating)
            {
                int pos = radTextBox1.TextBoxElement.TextBoxItem.SelectionStart;
                updating = true;
                radTextBox1.Text = textInfo.ToTitleCase(radTextBox1.Text);
                radTextBox1.TextBoxElement.TextBoxItem.SelectionStart = pos;
                updating = false;
            }
        }

RadDateTimePicker - allow entering date, month and year without using space key to navigate between the date, month and the year, just like in RadMaskedEditBox

FIX. RadDateTimePicker - setting the value to null, should clear the selection

RadMaskEditBox does not apply the mask when the value is pasted from context menu. Same works when the value is pasted with Ctrl+V.

To reproduce:
- set the Mask to N2
- set the MaskType to Numeric
- set the control value to 4.456789

The the control displays 4.456789 instead of 4.46

WORKAROUND: 
  Private Sub RadMaskedEditBox1_ValueChanged(sender As Object, e As EventArgs)
        Dim control As RadMaskedEditBox = DirectCast(sender, RadMaskedEditBox)
        RemoveHandler control.ValueChanged, AddressOf RadMaskedEditBox1_ValueChanged
        control.MaskedEditBoxElement.TextBoxItem.Text = control.MaskedEditBoxElement.Provider.ToString(False, True)
        AddHandler control.ValueChanged, AddressOf RadMaskedEditBox1_ValueChanged
    End Sub

Steps to reproduce:
1. Add a RadDateTimePicker to a form.
2. Set ShowUpDown to true.
3. Set NullDate to be DateTime.Now
4. Set MinValue to DateTime.Now.Date
5. Set MaxValue to DateTime.Now.AddDays(1).AddSeconds(-1)
6. Try to change the value and press tab to save the value. The value will be set to null.

RadTextBox should indicate ReadOnly state

How to reproduce: also check the attached video
this.radMaskedEditBox1.MaskType = MaskType.Numeric;

Workaround:
private void RadMaskedEditBox1_TextChanged(object sender, EventArgs e)
{
    if (this.radMaskedEditBox1.Text == "-0")
    {
        if (this.radMaskedEditBox1.MaskedEditBoxElement.TextBoxItem.Text.Length == 2)
        {
            //Workaround
            this.radMaskedEditBox1.MaskedEditBoxElement.TextBoxItem.Text = this.radMaskedEditBox1.MaskedEditBoxElement.TextBoxItem.Text.Remove(1, 1);
        }
    }
}

Workaround: Users should use a N0 mask instead of G mask.

RadMaskedEditBox is not able to edit the value when MaskType is set to Numeric, Mask to percentage and CultureInfo NumberFormat CurrencyGroupSeparator is set to "."

Workaround:
CultureInfo ci = new CultureInfo(Thread.CurrentThread.CurrentCulture.LCID, false); //do not use user settings
 
Thread.CurrentThread.CurrentCulture = ci;

In certain cases RadSpinEditor.Value property is not updated correctly. This happens, because RadSpinEditor does not lose focus as it is supposed to.

Place a RadTextBox on a form and set its anchor to Left, Top, Right. Show the form in a maximized mode. You will notice that the RadTextBox is longer than it should be. The workaround concerns setting the AutoSize property of RadTextBox to false.

Click the scroll bar in the Color Dialog web page closes the dialog.

Currently there can only be one delimiter in the autocomplete box. Different users might be accustomed to using different delimiters, even one user using several delimiters.
