Hi,
I have a requirement to render the contents from excel to word. With a condition that the content after rendering to word should look like they way it is displayed in print preview mode of excel. Can anybody help me on this?
To give additional information, I need the properites set in excel also to be rentered while rendering to word.
For example: If the mode is set to landscape in excel I want the same mode to be set in word after rendering. Similar with boarders, margins, print area and scalings.
