Event Data
The CustomDrawWeekViewTopLeftCorner 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. |

ObjectInfo | Gets information on the painted element. |
The event data class exposes the following methods:
Method | Description |
---|---|
DrawDefault() | Renders the element using the default drawing mechanism. |
Remarks
The CustomDrawWeekViewTopLeftCorner event is raised by the WeekView, MonthView and the TimelineView when they are grouped by dates (SchedulerViewBase.GroupType is set to the SchedulerGroupType.Date). This event occurs before the top left corner of the view is painted.
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 painting.
Example
This example inserts text in the top left corner of the WeekView view and its descendants - the MonthView and the TimelineView views.

e.DrawDefault();
UpperLeftCorner objectToDraw = e.ObjectInfo as UpperLeftCorner;
string text = "Employee";
// Draw the text rotated 45 degrees counterclockwise.
Font myFont = objectToDraw.CaptionAppearance.Font;
SizeF textSize = e.Graphics.MeasureString(text, myFont);
e.Graphics.TranslateTransform(e.Bounds.Width / 2, e.Bounds.Height / 2);
e.Graphics.RotateTransform(-45f);
e.Graphics.DrawString(text, myFont, Brushes.Blue, -(textSize.Width / 2.0f), -(textSize.Height / 2.0f));
e.Graphics.RotateTransform(45f);
e.Graphics.TranslateTransform(-e.Bounds.Width / 2, -e.Bounds.Height / 2);
