Add Search functionality

hi , actually in a wpf application in expression blend i created may pages interlinked, containing texts, documents, images etc and wanted to add a search button at the top of every page, which would search all the keywords matched in a textbox in all the pages of the application. which ever page the search is matched it brings up that page and highlights the word..

It's a very broad question. What type of search, depending on what, etc, all these things needs to be answered by you before we can attempt to answer. Still I'll make a shot.

If you are doing a simple search based on keywords or search terms, you can have a text box and search within a database and display the results in a datagrid.

Alternatively you can "select" the search criteria instead of typing it...for eg, select customer id from combo box. Logic for search will remain same as it used to be in Winforms or other apps.

So now tell us in more detail what you expect.
