@SVP: Have you tried to replace the escaped entities as well as their respective encoded equivalents?

Very useful post. I used it on 2010 SP site. But I face one issue. If the text contains & and " , it is escaped as & and I can not get rid of the & or "

Any ideas here?

Yes i did and the problem is that my each news item is a page inside the news site so what i get is the titles of these pages.

@Abdellatif: You could do this using the CQWP. Have you tried it yet?

@varun: Yes, it's a known issue which has to do how the Content Query Tool Part works. As soon as you set the value of the ContentQueryOverride property, CQTP adds an extra warning saying that not all properties are available because of the override. Because the warning wasn't visible on the previous postback, the exception is being thrown. I admit it's annoying but it's not really something we can do much about.

Hi Waldek,

I am trying to add a CAML Query in "Query Override". I have overrided the "Apply Changes" metiod of toolpart class and setting the "Query Override" property there.

When i click on "Apply" and then "Ok" in the Tool Part
i am getting the below error.

"Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request."

Please do reply ASAP..

@Michael: Although I haven't tried it with SharePoint 2010, the XSLT is so simple that I can't image there would be a SharePoint 2010 specific error in it. I think that it would be useful to have a closer look at the error that you're getting. Did you know that the CQWP does some great logging into ULS, so basically every XSLT exception that you get (including the details) is being logged to ULS? It might be useful to browser through ULS to find the specific error that you're getting.

Have you tried it with SP 2010? When I tried applying it to the ContentQueryMain.xsl and ItemStyle.xsl of a Publishing Portal site collection it worked. But for some reason it caused the two Summary Links web parts on the page to crash with the message "Unable to display this web part…".
