Custom items in WPF Calendar

Expanding on the previous post we will now modify the appearance of the calendar items through the use of a custom item presenter. To define the new presenter, simply create a new Style resource with TargetType set to ItemPresenter and place this Style somewhere in the resource look-up path – for example in the application’s or the window’s resource dictionaries. The Style must contain a setter for the Template property that defines the appearance of the item:

<style targettype="{x:Type planner:ItemPresenter}">
  <Setter Property="Template">
      <ControlTemplate TargetType="{x:Type planner:ItemPresenter}">

In this particular case the presenter represents a grid with two rows. The top row contains an icon and the header text of the item. The bottom row contains the description text. Note, that the TextBlock displaying the header text of the item has a name – HeaderBlock. The element with this name defines the position of the TextBox when the item is in-place edited.

Various appearance properties are also customized – such as FontFamily, Background and BorderBrush, by assigning new values to the respective properties of the Calendar.ItemSettings.CalendarStyle object:

calendar.ItemSettings.CalendarStyle.FontFamily = new FontFamily("Segoe UI");
calendar.ItemSettings.CalendarStyle.Background = Brushes.White;
calendar.ItemSettings.CalendarStyle.BorderBrush = Brushes.SlateGray;

Finally, the size of the calendar lanes is increased to accommodate the new appearance of the items:

calendar.ResourceViewSettings.LaneSize = 54;

The final result is displayed below.

Implementing drag & drop in MindFusion.Scheduling for WPF

In this post we will discuss how to implement drag & drop using MindFusion.Scheduling for WPF. The goal is to enable users to create appointments by dragging items from an external source and dropping them onto the Calendar control surface.

The source

For the purposes of this sample the drag & drop source would be a simple ListBox control. The following XAML declares a ListBox with several predefined items:

  Task #1
  Task #2
  Task #3
  Task #4
  Task #5
  Task #6

The calendar

To enable the Calendar control to be the target of drag & drop operations, set its AllowDrop property to true. The following XAML snippet illustrates the definition of the Calendar control:

<planner:calendar x:name="calendar" grid.column="1" currentview="ResourceView" grouptype="GroupByResources" theme="Silver" allowdrop="True">
    <planner:resource name="Resource #1">
    <planner:resource name="Resource #2">
    <planner:resource name="Resource #3">

The calendar is set up to display three resources in a Resource view.

The drag & drop

The drag & drop operation is initiated by calling the DragDrop.DoDragDrop static method and passing a reference to the dragged data. In our case we would want to initiate drag & drop when the user clicks on an item in the ListBox and starts dragging. Because the MouseDown event is consumed by the ListBox when the mouse is pressed over an item, we need to handle the PreviewMouseDown event. The following C# code displays the handlers of the PreviewMouseDown and MouseMove events:

private void taskList_PreviewMouseDown(object sender, MouseButtonEventArgs e)
  mouseDown = e.LeftButton == MouseButtonState.Pressed;

private void taskList_MouseMove(object sender, MouseEventArgs e)
  if (taskList.SelectedItem != null && mouseDown)
    mouseDown = false;
    string data = ((ListBoxItem)taskList.SelectedItem).Content.ToString();
    DragDrop.DoDragDrop(taskList, data, DragDropEffects.Copy);

To give visual feedback to the user when the mouse moves over the Calendar control during drag & drop operation, handle the DragOver event:

private void calendar_DragOver(object sender, DragEventArgs e)
  e.Effects = DragDropEffects.None;
  if (e.Data.GetDataPresent(typeof(string)))
    DateTime? date = calendar.GetDateAt(e.GetPosition(calendar));
    if (date != null)
      e.Effects = DragDropEffects.Copy;

This handler checks whether the dragged data matches the expected type and whether the location under the mouse cursor represents a valid date.

Finally, handle the Calendar.Drop event. This event is raised when the user releases the mouse over the Calendar control during a drag & drop operation.

private void calendar_Drop(object sender, DragEventArgs e)
  if (e.Data.GetDataPresent(typeof(string)))
    Point point = e.GetPosition(calendar);
    DateTime? date = calendar.GetDateAt(point);
    Resource resource = calendar.GetResourceAt(point);
    if (date != null && resource != null)
      string task = (string)e.Data.GetData(typeof(string));
      Appointment appointment = new Appointment();
      appointment.HeaderText = task;
      appointment.StartTime = date.Value;
      appointment.EndTime = appointment.StartTime.AddDays(2);

The following image shows the running sample with several created appointments:

MindFusion.Pack for WPF 2013.R1

We have just has released MindFusion.Pack for WPF 2013.R1. There are new features in most of the components in the pack. Here are the details:

Support for VisualStudio 2012

The pack installer creates VS2012 toolbox palette for all the components and can optionally install VS2012 sample projects. Toolbox palettes are also created for all .NET target environments supported by the respective Visual Studio versions.


Style and Themes

Styles define the appearance of a given chart element – the axis, the series, the legend. Each ChartTheme is a collection of styles. You can:

• create themes based on the appearance of an existing chart
• create themes with the ThemeEditor tool
• save themes to XML files
• load themes from XML files
• use a number of predefined themes

The green theme

Improved Design Time Support

You can now edit all collection properties, including the Series collection, the brushes, strokes, legends and all other collections in design time through the property grid.

Axis Intervals

The new AxisSettings.IntervalCount property lets you specify the exact number of intervals at the axis. In such case the control does not use the Interval property and calculates the value of each interval based on AxisSettings.Min, AxisSettings.Max and AxisSettings.IntervalCount.

API Changes


Preserve order in tree layout

You can set now the Balance property of the TreeLayout to Preserve if you want to keep the original geometric order of child nodes when arranging them under their parent. This can be used to arrange tree branches in a specific order by first positioning them in increasing horizontal or vertical positions.

Selection improvements

  • Set Behavior to SelectOnly to let users select existing items, but not modify them or draw new ones.
  • Use the SetsDirtyFlag property of the Selection class to specify whether the Dirty flag should be set when selection changes.
  • The SelectionStartMoving event is now raised when the user begins moving multiple selected items.
  • Use the ToggleSelection modifier key to select or deselect items by clicking. The key disables selection via lasso rectangle.


Container nodes

Container nodes



You can now use the new PdfExporter and MhtmlExporter, which enable exporting to the PDF and MHTML formats respectively. You can find detailed information about the new exporters in the “Exporting Reports” theme.

Side-By-Side Containers

You can arrange items parallelly by putting them inside the new SideBySideContainer report item. You can use it, for example, to display two (or more) data ranges one next to the other.

• New DefaultEncoding property in PdfExporter;
• New Median aggregate function;


Improved item presenter

The ItemPresenter class gives you the start and end time of the represented item fragment through the new
StartTime and EndTime properties. In addition, derived classes can override the new OnStartTimeChanged,
OnEndTimeChanged, and OnItemPropertyChanged methods to get notified when the StartTime or EndTime properties change or when any property of the underlying item changes.

Item recurrence

Improved recurrence

You can validate and customize the occurrences of a recurrence pattern with the new ValidateOccurrence event of the Recurrence class.
