Getting the Cursor causes a resize on the underlying control
posted

Hi,

I observed a strange behavior with cursors. When I check the current cursor, I get a resize event. Could you explain that?

statement:
UserControl.Cursor != Cursor.Default

causes the following stack trace below. Somehow the infragistics library changes the bounds of the control while checking the control's cursor. It is especially strange, as we do not set the cursor but only get the cursor value.

Regards,
Reto

    The UltraDockManager lazily repositions and resizes docked controls to be in the rect of their pane. This happens when a repaint occurs or at some other time when UIElements are verified, such as when getting a Cursor, since this requires appearance resolution of the elements and therefore requires that they be updated with the current state of the control. If panes were resized or moved and you are asking for the Cursor before a repaint has occurred, this is correct. If not, it may be a bug and should be submitted to Developer Support.
