If assign a value using a percent mask the value isn't displayed as it should - assign a value of 0.08 I expect the control to display  "8.00 %", instead it displays "0.08 %"

Steps to reproduce:

radDateTimePicker1.Value = DateTime.Today; 
radDateTimePicker1.SetToNullValue(); 
radDateTimePicker1.Value = DateTime.Today;

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();
               
            }

To reproduce:
1.Add a RadAutoCompleteBox to a form. 
2.Add AutoCompleteItems.
3.Start the project.
4.AutoComplete a word and write some normal text.
5.Change few themes (mainly office themes) you will notice that the text's position shifts down.

Workaround:
Clear each TokenizedTextBlockElement's bottom Margin from the themes using VisualStyleBuilder.

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);
     }
 }

FIX. RadDateTimePicker - when the NullDate is set for example to DateTime.Now and you clear the value with SetToNullText, then you can not type the value for the current month.

Setting the ActiveMode property does not change the initially selected tab of the RadColorDialog.

RadColorDialog ignores some of the values provided in the overridden GetLocalizedString method. These are for example the tabs of the RadPageView.

Exception is thrown on key press if RadMaskedEditBox has MaskType set to Numeric, Mask to C2, and Value to Null.

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

Make the Title of RadColorDialog accessible in the ColorDialogLocalizationProvider class

A nice add-on to the control would be having Get/SetTextField methods, allowing for complete customization of each masked field.

A possibility to specify the default time (to be different from 00:00) when choosing date value from the drop-down calendar.

Add a functionality that allows the user to disable the spin editor like behavior when the MaskType is setting to Numeric.

RadTextBox does not serialize its Size if it has been added into FlowLayoutPanel, and in run time it has incorrect size.

If you put RadTextBox on a form, set its Anchor to Bottom \ Left and you show the form using the following code:
            RadForm1 rf = new RadForm1();
            rf.MdiParent = this;
            rf.WindowState = FormWindowState.Maximized;
            

RadColorDialog does not work when assemblies has been merged, because RadColorEditor's CreateColorSelectorInstance method has hardcoded search for Telerik.WinControls.UI.dll assembly.

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); 

RadColorDialog is not localized properly when an instance of it is created after the localization provider is set.
