Write A Class For Retrieving IEnumerable Objects In EF And C#?

In my Code Behind I use several times this code below to bind and rebind (for refresh) e GridView after an insertion or other operations completed using EF objects.

Using a simple gridview.DataBind(); does not work because I call EF programmatically so I thought to use a Class to keep in memory this code that can create Objects for my GridView and call it how many time I need in my code avoiding redundancy.

IEnumerable<CmsContent> queryContents = myCurrentSlot.CmsContents.Where(x => x.IsPublished == true);
uxManageContents.DataSource = queryContents;
uxManageContents.DataBind();

Or do you know a batter way to Refresh the gridview after EF executing some commands? how to do it?

remember that I do use any data source web control for the gridview but i bind it programmatically.
