Why all my links opening in a new Window?

问题:

Recently i upgraded a web project from Framework 2.0 to 4.0

On my main page there are several links. Upon clicking on them it opens within the same window.

There is one link to a page which contains a Crystal Report Viewer. Once i visit that page and return back to the main page, after that clicking on any link opens it in a new window !!

I double checked my urls, there is nothing wrong with them.

What is causing this behaviour ? and how do i prevent this ?

NOTE : The pages load inside a frame

thanks

EDIT : This happens in IE only

EDIT 2 : I also tried suggestion by Krik in this post ASP.NET child window opens up on a new window on every post back and added <base target="_self"> but it is not working.

EDIT 3 : This how my links are

<a class="MenuLinks" target="display" href="../REP/LdgrRep.aspx?pageId=34&mId=1&subModuelId=3">Party Ledger</a>

where display being the name of my frame.

You mention the name of your frame is display. Also make sure to set the id to display too.

This may explain your issue. Some browsers work with both name and id for this and some don't.

In the HTML code when you make a link tag if you have target="_blank" that causes it to open the link in a new window.
