您需要确保它是项类型，而不是命令项

     if((e.Item.ItemType == ListItemType.Item) ||  (e.Item.ItemType == ListItemType.AlternatingItem))
     { 

       var RadDropDownList = (RadDropDownList)e.item.FindControl("ddlAlbums");

        if(RadDropDownList != null)
        {
            //do what you need here
         }
     }

FindControl是否不起作用？RadGrid1中的

ddlAlbums

在哪里？RadGrid1中的@VDWWD是

     if((e.Item.ItemType == ListItemType.Item) ||  (e.Item.ItemType == ListItemType.AlternatingItem))
     { 

       var RadDropDownList = (RadDropDownList)e.item.FindControl("ddlAlbums");

        if(RadDropDownList != null)
        {
            //do what you need here
         }
     }
