Document.Insert (myText, null) null style giving error now

[danparker276]

I updated my Silverlight libraries and my code where I would insert at points into a rich text box would throw an error now.  I haven't updated in a 3-6 months (internal builds).  I fixed it by just doing a Insert with out the document and it works.
Old code:
this.myRichTextBox.Document.Insert(myText, null);

New code:
this.myRichTextBox.Insert(myText);

It seems to work ok like this and inserts in the right place.  Anything wrong with what I'm doing?

I don't really care about styles.  I really only use the rich text box because I like it's spell checker with the red line under the word.  I just use it as a regular text input box.

Hello Dan,

In the latest Q3 release - 2011.3.1116 we introduced a new functionality - styles. Before, the StyleDefinition objects were only used to set local values of the properties such as FontSize, FontWeight, etc. With the new implementation, setting a style with value null will be a problem.

Overall, you have two solutions:
1. Create a StyleDefinition, set some of its properties and pass it as an argument.
2. Use the method or RadRichTextBox.

There are code-snippets with both approaches and a description of the difference in this article. The main difference is that the undo/redo stack will be cleared if you use the Insert method of RadDocument as you have been doing by now.
