I am generating fairly large documents using C1PrintDocument and would like C1Preview to update each time a page is generated.

What is the best way to do this?

What version of C1Preview you use?

By default C1Preview updates automatically when content of connected C1PrintDocument changed.

For example, this code update preview each time when new page added:

preview.Document = c1PrintDocument;
for (int i = 0; i < 200; i++)
    c1PrintDocument.Body.Children.Add(new RenderText("SomeText"));
c1PrintDocument.Generate();
 

I am using version 2.0.20063.41006.

I'm using doing something like this for each page:

m_rengr = New C1.C1Preview.RenderGraphics

Then, I am rendering my page on m_rengr.  There is a really long delay while every page is generated, and then I get all the pages filling out at once at the same time.

So (along with my previous reply), There is roughly a minute of delay while every page is generated and added to the document) and all the pages appear at once in about a second at the end.

 Is there any kind of call I can make between each page that will force the preview to update smoothly?

All document is a single RenderGraphics object?
