New Features:

• Added MasterUISlave property to the Plot Axis objects.
• Modified property editor value Edit boxes to squash all exceptions due to invalid inputs. After the exception is squashed, the Edit box will return to the previous valid value. This was done due to eliminate developer confusion over how to handle application exceptions. Most developers where not handling the exception. This resulted in an unhandled exception dialog being displayed to the end-user, and many end-users would click the wrong button, causing the application to terminate.
• Added new XValueTextDateTimeFormat property to the Plot control. This property allows you to specify if x-value is formatted in Double or DateTime format when saving or copying data to the clipboard. When setting this property to DateTime, the x-axis text formatting style property must also be set to DateTime or DateTimeUTC.
• Added new GetXText method to all plot channels. This method is in support of the XValueTextDateTimeFormat property mentioned previously.
• Upgraded Plot Differential channel drawing routines to support null data-points.
• Added horizontal scrolling to all Iocomp property editor listbox controls. The horizontal scrollbar only appears when the width of an item exceeds the width of the display area.
• Added logic to the design-time property editor to auto-increment the OPCGroup object's Name property when a new one is added.
• Changed the default value for the OPCItem's Name property to be "Item???". This is to help remind the developer to set the value.
• Upgraded the MatrixButton control to support buttons with a momentary style. The MatrixButtonStyle enumeration has a new value called MomentaryButton. Use the Style property on the MatrixButton class to specify its type. The MatrixButton class also has a new property called Value, which is of type ValueBoolean. When the button's Style is set to MomentaryButton, and the mouse left button is depressed over the MatrixButton, the MatrixButton Value property will changed to True. When the mouse is released, the Value property will return to False. When connecting an OPC-Link to the MatrixButton, be sure to specify the Value.AsBoolean sub-property (Example, the OPC-Link PropertyName setting would be "Buttons(1).Value.AsBoolean". The "Buttons(1)" portion specifies the second button in the Button collection (Zero Based Index), and use "Value.AsBoolean" as the property on the button class).
• Added Cubic-Spline, Polynomial, and Rational channel types to the Plot control.

Bug Fixes:

• Fixed AutoSize property default and streaming issue in VS2005 and above. Due to conflict with new virtual AutoSize property added by Microsoft. Started with the VS2005/2.0 framework.
• Fixed the Plot control's Channel type data-cursor interpolation issue when working with the Differential channel type. The data-cursor would perform linear interpolation between data-points. It now shows the horizontal differential value.
• Fixed MatrixButtons and MatrixLeds design-time property editor item scrambling issue. Would result in the settings between elements to be shifted or dropped.
• Fixed Plot control Text Annotation offset drawing occur. Would only occur when the Rotation property was set to a non-zero value.
• Fixed OPC design-time property editor scrollbar issue. When the Control-Name or Property listbox needed to show a scrollbar, the bottom portion would by partially clipped.
• Fixed Plot Toolbar control Enabled property issue. If the Command property where set to None, the button would initialize Enabled property to False, regardless of its setting at design-time. Before this fix, the only workaround was to set the Enabled property of the button to True through code at run-time.
• Updated design-time transparency update issue on the Knob, GaugeAngular, GaugeLinear, SlidingScale, SlidingCompass, and Led controls. At run-time, the controls would correctly draw themselves and show their background transparently.
• Fixed Iocomp property-editor cut/copy/paste/undo problem. Would result in the listed keyboard commands being ignored. Only occurred on edit box controls which were configured to edit integer and double data types. For string data types, the cut/copy/paste/undo feature would work correctly.
• Fixed axes Color property streaming bug. This property would never stream. (Note: All defaulted Iocomp properties will not stream, and this is the normal behavior. All property saving is differential, and this is for performance reasons.)
• Fixed OPC-Data control link updating bug. This bug would only occur when the link was made to a control which was a child of a container control. All controls directly added to a form (The form was the container control) were not affected.
• Fixed OPC design-time property editor bug which effected the DataType property combo-box edit control. When selecting items further down in the list, the returned value would not match the actual item index and setting would shift one or more values. This bug did not effect settings to the DataType property made through code.
• Fixed drawing error on the PlotChannelBiFill class. Would result in sloped lines being drawn above or below of the bi-fill Reference setting. For example, if red was to be drawn above the reference, and blue below the reference, the red would bleed over the reference line, and a portion would appear as a sloped fill in the blue area.
• Fixed OPC-Data control property editor bug. Occurred when trying to set the OPCItem.DataType property. Starting with the VT_DECIMAL enumeration setting, the pull-down combo-box values would start to diverge after making a change to VT_DECIMAL, or further down in the list.
