When working with RadAutoCompleteBox if one tries to remove a token from the collection through clicking on the close "x" button of the token the TextBoxElement of the text box loses focus, even though it look as if it still contains it.

To reproduce:
- Use RadTimePicker in a project and apply the Aqua theme to it.

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

KeyPress, KeyDown etc. events are not firing.

The RadTextBox control should rise the PreviewKeyDown event.

Expose the AutoCompleteDropDown so it's behavior can be customized and the user can subscribe to its events for example.

To reproduce:
Add RadAutoCompleteBox
Add AutoCompleteItems
Change the theme to Office2010BlueTheme, Office2010BlackTheme, Office2007SilverTheme or Office2010SilverTheme.
Write something - looks good
Autocomplete a word and now write something - text is a few pixels lower.

Workaround:

void radAutoCompleteBox2_TextBlockFormatting(object sender, TextBlockFormattingEventArgs e)
{
    TokenizedTextBlockElement token = e.TextBlock as TokenizedTextBlockElement;
    if (token != null)
    {
        token.Margin = new Padding(0, 1, 1, 1);             
    }
}

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.

To reproduce: 
- Set the NullableValue property to null. 
- When you start the application there is no date in datetime picker but when the control loses the focus the date is automatically filled.

Workaround: 
- Set the NullDate to equals the Value: radDateTimePicker1.NullDate = radDateTimePicker1.Value; 
- Then you change the NullDate in the ValueChanged event: 
void radDateTimePicker1_ValueChanged(object sender, EventArgs e) { radDateTimePicker1.NullDate = new DateTime(1980, 1, 1); }

To reproduce: Add a TableLayout and in the cells add a RadtextBox with its multiline property set to true. Resize the form until the textboxes and unclickable and no scrollbars are shown. This behavior does not always occur.

Workaround: Use a custom RadTextBox class: public class MyTextBox : RadTextBox { protected override void InitializeTextElement() { this.GetType().BaseType.GetField("textBoxElement", BindingFlags.Instance | BindingFlags.NonPublic).SetValue(this, new MyTextBoxElement()); this.TextBoxElement.StretchVertically = true; this.TextBoxElement.ShowBorder = true; } } public class MyTextBoxElement : RadTextBoxElement { protected override SizeF MeasureOverride(SizeF availableSize) { availableSize.Width -= BorderThickness.Size.Width; availableSize.Height -= BorderThickness.Size.Height; SizeF desiredSize = this.MeasureChildren(availableSize); return desiredSize; } protected override Type ThemeEffectiveType { get { return typeof(RadTextBoxElement); } } }

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

You guys expose most of the properties from the "HostedControl" on your custom controls.  One that seems to be missing, and requires an unintuitive line of code is the "UseSystemPasswordChar" boolean property from the TextBox.  I think it makes a lot of sense to expose this.

See: http://www.telerik.com/forums/usesystempasswordchar-property-for-radtextbox

To reproduce:
- add a RadMaskedEditBox with MaskType = MaskType.Standard
- input some numbers to fill all the expected digits
- select the content in the RadMaskedEditBox and press Enter key. As a result the last number is removed

Workaround:
private void radMaskedEditBox1_KeyPress(object sender, KeyPressEventArgs e)
        {
            e.Handled = e.KeyChar == (char)Keys.Return;
        }

Currently it is not possible to represent time as 24:00 in time picker control as it uses the .NET DateType type, which does not support "24:00" as valid time.

To reproduce:
- add a RadButton and a RadTimePicker;
- on RadButton.Click dispose the existing RadTimePicker and create a new one;
- continue clicking for a while and notice that memory consumption is rising.

Improve the RadTextBoxControl to allow different text alignment as Microsoft TextBox.

To reproduce:  
            RadTextBox txtAction = new Telerik.WinControls.UI.RadTextBox();
            txtAction.Dock = System.Windows.Forms.DockStyle.Fill;
            this.Controls.Add(txtAction);

Workaround:
void txtAction_Resize(object sender, EventArgs e)
{
            txtAction.TextBoxElement.InvalidateMeasure(true);
            txtAction.TextBoxElement.UpdateLayout();
  }

RadDateTimePicker memory leak, when calendar popup is opened more than once.
