You can force that behavior!
There is no way to tell via HTML and/or JavaScript where to open the content of a link...
(to be more precise there is a target attribute on the <a> element but it can not be used to distinguish between new window and new tab...)

javascript excuting from .cs page has no control over the users current browser instance... so it can not open file in a new tab 

Alternative would be binding a anchor tag dynamically with target='_blank'

That will not do - "_blank" only tells browser to open link in new instance, but do not decide if it is a new window or new tab...

here is a sample code that worked for me before, a label placed in gridview and binded from .cs page... on clicking it opens file in new tab...

lblF1.Text = "<* href='\\File\\" + Convert.ToString(_dt.Rows[0]["varFile"]) + "' target=_blank>Open File ";

* == a

It is because the way your browser configured and not because of the "_blank" target!
For instance the very same link, with "_self", will open in the same window with right click, but in new tab with middle click in most browsers, but can be changed...
