Hello Experts,<br />
<br />
I'm loading a large text file (5mb) into a richtextbox. &nbsp;However it is very slow to load. &nbsp;The line below is taking too long.<br />
<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; TextRange range = new TextRange(PART_RichTextBox<wbr />1.Document<wbr />.ContentSt<wbr />art, PART_RichTextBox1.Document<wbr />.ContentEn<wbr />d); &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;<br />
range.Load(textStream, GetFileDataFormat(this.Vie<wbr />wModel.Get<wbr />FileType()<wbr />)); &nbsp;<br />
<br />
<br />
How can I the improve performance? &nbsp;<br />
<br />
Thanks,<br />

Hello Experts,

I'm loading a large text file (5mb) into a richtextbox.  However it is very slow to load.  The line below is taking too long.

              TextRange range = new TextRange(PART_RichTextBox1.Document.ContentStart, PART_RichTextBox1.Document.ContentEnd);                            
range.Load(textStream, GetFileDataFormat(this.ViewModel.GetFileType()));  


How can I the improve performance?  

Thanks,
Steve
