Problems with splits

Hello,

I am new with SyntaxEditor At the moment I am testing the evaluation version, I include the SyntaxEditor in a Project to substitute my poor-friendly RichTextBox editor, and now I am testing the editor features. After some tests I found tree problems with splits:

Problem 1) If I follow this sequence I get an NullReferenceException:

1) Split Horizontal with this code:

if (currentMenuEditor.Document.HasVerticalSplit)
currentMenuEditor.Document.VerticalSplitPosition = 0;
if (!currentMenuEditor.Document.HasHorizontalSplit)
{
currentMenuEditor.Document.HorizontalSplitPosition = (int)
(currentMenuEditor.Document.DisplayRectangle.Height / 2);
}

2) Split Vertical with this code:

if (currentMenuEditor.Document.HasHorizontalSplit)
currentMenuEditor.Document.HorizontalSplitPosition = 0;
if (!currentMenuEditor.Document.HasVerticalSplit)
{
currentMenuEditor.Document.VerticalSplitPosition = (int)
(currentMenuEditor.Document.DisplayRectangle.Width / 2);
}

3) This exception is thrown:

System.NullReferenceException: Object reference not set to an instance of an object.

**********************************

Problem 2) If I use the mouse to split the editor, and if I move the mouse quickly to remove a "split", sometime the split button is not showed correctly and some scrollbars are not hiding. I would publish an image showing the situation if I could publish images in this forum.

**********************************

Problem 3) This it is a minor problem. While I am splitting the editor there is a delay when drawing that produces a "wake effect". During a moment you could see the same scroll bar drawn in several places.

The effect could be reduced using the WM_SETREDRAW API. Other option in order to avoid to use the GDI API could be perform the resize operation in the Idle event. So, after you resize the views the editor is painted immediately.


Finals notes: I couldn't reproduce problem 1 and 2 in your examples. Maybe there is some other control in my project that it is affecting the SyntaxEditor.

Any help?, thanks,
