Custom items in WPF Calendar

Posted on by

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">
    <Setter.Value>
      <ControlTemplate TargetType="{x:Type planner:ItemPresenter}">
        <Grid>
        ...
        </Grid>
      </ControlTemplate>
    </Setter.Value>
  </Setter>
</style>

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

Posted on by

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:calendar.itemresources>
    <planner:resource name="Resource #1">
    <planner:resource name="Resource #2">
    <planner:resource name="Resource #3">
  </planner:resource></planner:resource></planner:resource></planner:calendar.itemresources>
</planner:calendar>

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);
      appointment.Resources.Add(resource);
      calendar.Schedule.Items.Add(appointment);
    }
  }
}

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

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:

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.
