I have taken over a Sharepoint 2007 site and been tasked to migrate / recreate much of it to a separate Sharepoint 2010 site. I am still learning many aspects of Sharepoint. The old site has many pages that have custom dataview webparts displaying information from lists in tables, different ways, based on who is signed in etc.
1.) Is there a recommended way for modifying this stuff? I see there is XSL editor and Parameters Editor on the webpart menu. There is also the code when I export the webpart and finally the list of code in SPD. Is there pitfall from updating these using one way or the other?
2.) Is there / what would be the best way to copy these or the xsl from these if they are reusable from 2007? I understand the GUIDs on my lists would be different, but should I change anything else?
3.)How does the <'xsl> tie together with the rest of it like your datasource, fields etc
4.) Is there recommended reading somewhere for how to go from inserting an empty dataview to correctly formatted data with custom edited xsl / html from start to finish? All I can find is snippets of everything in between and I am struggling to put it all together. Can someone walk me through or send me somewhere that goes A to Z from inserting dataview, changing the xsl, modifying adding fields or modifying your result set, and displaying those modified results in a custom way (say a table with a picture next to each item in a row).
I know it's a lot. Thanks.
