SchedulerControl.CustomDrawGroupSeparator Event

Enables group separators to be painted manually.

Namespace: DevExpress.XtraScheduler

Assembly: DevExpress.XtraScheduler.v19.1.dll

Declaration

public event CustomDrawObjectEventHandler CustomDrawGroupSeparator
Public Event CustomDrawGroupSeparator As CustomDrawObjectEventHandler

Event Data

The CustomDrawGroupSeparator event's data class is CustomDrawObjectEventArgs. The following properties provide information specific to this event:

Property Description
Bounds Returns the bounding rectangle of the drawing area.
Cache Gets an object which specifies the storage for the pens, fonts and brushes. Use it for custom painting in Scheduler Reports.
Graphics Gets an object used for painting.
Handled Gets or sets whether an event was handled. If it was handled, the default actions are not required.
ObjectInfo Gets information on the painted element.

Remarks

The CustomDrawGroupSeparator event occurs before a group separator is painted. The event parameter's CustomDrawObjectEventArgs.ObjectInfo property provides required information to paint the group separator.

You can call the CustomDrawObjectEventArgs.DrawDefault method to perform default painting before applying custom draw.

Set the CustomDrawObjectEventArgs.Handled property to true to prohibit default separator painting.

Examples

The following code draws a custom image in the Group Separator bar.

CustomDrawGroupSeparator_New

public static void scheduler_CustomDrawGroupSeparator(object sender, DevExpress.XtraScheduler.CustomDrawObjectEventArgs e)
{
    e.DrawDefault();
    Image im = Image.FromFile("image.png");
    Rectangle imageBounds = new Rectangle(e.Bounds.X - (im.Width / 2), e.Bounds.Y, im.Width, im.Height);
    e.Cache.Graphics.DrawImage(im, imageBounds);
    e.Handled = true;
}
