Thanks for your reply John.Doe but I'm still stuck when trying to rebuild the project, maybe because I'm really new to the whole VWD .net stuff.
1) I have made the necessary changes to Tabs.css, (.ajax_tab_default .ajax_tab_header {}) to get rid of the wrap.
2) Now, under AjaxControlToolkitfolder, besides the subfolders (accordion, Tabs...) I have 4 files I AjaxControlToolkit.csproj, AjaxControlToolkit.dll, AjaxControlToolkit (PDB file) and AjaxControlToolkit (Visual studioStrong Name Key file). I open the AjaxControlToolkit.csproj in my project which of course has already the file I'm working on (with the tab stuff)
3) What do I do next, should I hit the Build button on the toolbar of the VWD. Can you literraly explain how do you build the project (do you run it?) That's where I'm stuck
4) Then I got the last step which simply consists in re importing the new tool kit elements (.dll) (Accordion, Calendar, Tabpanel) on the left toolbox to be then used on the page.
Thanks in advance for the help. That would give me such a relief.
Kind regards,
Jeewai
