Hi, I would like to define a custom style for milestones. How to do that?
It looks like a TimelineItem is regarded to be a milestone if it's duration is zero - I guess this is the standard behavior of RadTimeline.

In the examples, the ItemTemplateSelector-property of RadTimeline is used, and DataTemplateSelectors in the ViewModel. Do I have to use these to define my own style for a milestone?

And another (maybe tricky) question: Is it possible to define a style for a milestone like in the attached image, so that each milestone has a dashed line going from the top of the control to the bottom?
As I understand it, the positions of the TimelineItems are calculated by RadTimeline, so if the custom style of the milestones would include such a dashed line (which would be an element with a very large height) that would be a problem, I guess?

Dynamic LabelFormat?

Hello,

I'm currently getting myself introduced to ChartView and in my project I would like for the horizontal axis (DateTimeContinuousAxis) to dynamically select a LabelFormat depending on the time being presented. For full hours I'd like it to be "mm/ddd HH", otherwise just "HH:mm".

I'd prefer to do it in MVVM if possible but I'm not too religious about it. I have tried using a converter but I don't know how to obtain the actual value being affected by the format.

Can this be achieved?

How to edit GridViewCell from code?

I want to add "paste to selected cell" command to Row. I don't want to change SelectionMode="Extended".
I've added RoutedUICommand:

private void PasteToCell_Executed(object sender, ExecutedRoutedEventArgs e)
{
            GridViewCell cell = e.OriginalSource as GridViewCell;
            if (cell != null)
            {
                var value = Clipboard.GetText();
                cell.BeginEdit();
                TextBox tb = (TextBox)cell.GetEditingElement();
1 ->          tb.Text = value;
2 ->          if (ApplicationCommands.Paste.CanExecute(value, tb))
                    ApplicationCommands.Paste.Execute(value, tb);
3 ->         cell.Value = value;
4 ->         cell.SetCurrentValue(GridViewCell.ValueProperty, value);
5 ->         cell.SetValue(GridViewCell.ValueProperty, value);
                cell.CommitEdit();
            }
}
No one work. I don't know how to realize this feature.
