Feature request: change value on mouse wheel

Standard windows control can do this, and sometimes its very handy, especially when you need not to set some value but rather to change it live during some process. When control has focus and mouse whell is moved change it's value using SmallChange property.

It's very easy to implement and very comfortable to use. Thank you!

Programmatically expand/collapse Timeline Groups?

I have used the information at http://www.telerik.com/help/wpf/radtimeline-features-grouping.html#ChangingExpandableGroupsCollapsedState to set up the default values for expand/collapse*

I would like to add "Expand All" and "Collapse All" buttons to my page for the user's convenience, however, I can't find a way to do this; is it possible?

*: I have the style set so that all groups start expanded, but oddly, the first time the timeline draws data, the first group is NOT expanded even though the rest are. After this first time, everytime I change the collection bound to ItemsSource, all groups will be expanded

Single row with multiple drag items

I want to make a row with column headers with characters 'A' to 'Z', and then be able to drop items beneath these headers on a single row.
For example, item 1 can be dragged to column B, and item 2 to column H.
Is this even possible?

Copy Paste Appointment By CTRL+C/CTRL+V or ContextMenu

Hello Telerik ,
I can copy appointments in RadScheduleView by holding the CTRL key and dragging the appointment to the desired slot.
But I want to have this functionality in my ContextMenu or by using shortcuts.
Is there any way to make copy/paste work with standard keyboard shortcuts (CTRL-C/CTRL-V) or ContextMenu
?
Thank you in advance,
hiwa

Validationbehavior while cancel editing a cell

Hello,

I’ve found a strange behavior of the validation while cancel editing a cell. When I edit a cell and enter an invalid value it shows me, that there is an input error. Very nice and cool! But when I cancel the editing with the escape key, the cell resets the content to the previous value. If the previous value was invalid too, there is no error message.

Is there something I can do to fix the problem?

DataTemplate binding to arbitrary property?

Consider my DataTemplateSelector below. I want all my RadPropertyGrid to have this particular editor for all string properties. This implies a problem when binding to the property in XAML - since the property name is unknown! How can I get this working?

My initial thought was to map Path to the property so that I can later bind to the Path instead of a specified property name. Ideas?

public class MyPropertyGridDataTemplateSelector : DataTemplateSelector

{

public override DataTemplate SelectTemplate(object item, DependencyObject container)

{

var pd = item as PropertyDefinition;

if (pd != null && pd.SourceProperty.PropertyType == typeof(string))

{

/* Something like this?

pd.Binding = new Binding

{

Path = new PropertyPath(pd.SourceProperty.Name),

Mode = BindingMode.TwoWay,

UpdateSourceTrigger = UpdateSourceTrigger.LostFocus

};

*/

return FilePathDataTemplate;

}

return null;

}

public DataTemplate FilePathDataTemplate { get; set; }

}

Binding becomes a problem since the property name is unknown:

<local:MyPropertyGridDataTemplateSelector x:Key="dataTemplateSelector">

<local:MyPropertyGridDataTemplateSelector.FilePathDataTemplate>

<DataTemplate>

<Grid>

<Grid.ColumnDefinitions>

<ColumnDefinition />

<ColumnDefinition Width="Auto"/>

</Grid.ColumnDefinitions>

<TextBox Text="{Binding Path}" Grid.Column="0" />

<Button Content="..." Width="25" Height="25" Grid.Column="1" Command="{Binding DataContext.OpenCommand, RelativeSource={RelativeSource AncestorType={x:Type Window}}}" CommandParameter="{Binding Path}" />

</Grid>

</DataTemplate>

</local:MyPropertyGridDataTemplateSelector.FilePathDataTemplate>

</local:MyPropertyGridDataTemplateSelector>
