I am getting an error when i click new webpart in webpart gallery. I want to deploy my custom webpart to sharepoint webpart gallery. I try to look in sharepoint log. Sadly, there is no further info in sharepoint log. They dont even throw correlation number error.

  • what error are you getting? Did you check the ULS logs? Do you have a custom master page? Did you try to add the web part with the default master page set for the site?

  • Are you talking about the web part gallery or add new webpart menu?

  • when I click new webpart in webpart gallery. In NewDwp.aspx. The problem has solved now. After I googling, i know that the culprit is "return of smartpart" component. Many thanks all...

Are you using smart-part in your SharePoint site? If so, maybe you should install AJAX 1.0 in your web front-end server to solve that error. This is a common error when you dealing with smart-part. If not, just ignore my answer.

  • yes, i'm using smartpart in my sharepoint site. Gonna try your advice..
