MSSQL UPDATE command when SELECT is joining multiple tables from separate databases

I have a SQL select pulling data from 3 different views in 2 different databases:

SELECT A.[ItemKey], A.[TagID], A.[PersonKey], A.[PersonSite], A.[ItemClass], A.[Location], A.[ItemStatus], A.[Manufacturer], A.[Model], A.[SerialNumber], A.[SystemName], A.[PersonID], A.[CompanyName], A.[SiteName], A.[ItemType], B.[CarrierName], B.[CarrierID], B.[TrackingNum], B.[Notes], C.[FirstName], C.[LastName]
FROM DATABASE.dbo.[View_OPS_ItemTags] A
INNER JOIN DATABASE2.dbo.[View_ItemTracker] B ON A.[ItemKey] = B.[ItemKey]
INNER JOIN DATABASE.dbo.[View_UserList] C ON C.[UserKey] = B.[UserKey]
WHERE ((A.[PersonID] = @PersonID) AND (A.[ItemStatus] = @ItemStatus)) ORDER BY A.[TagID]

This works great and display the data exactly how I need but I'm having trouble creating the controls to update the items in the GridView I have generated. I can create a separate gridview using just tables and modify the data with standard gridview edit controls but when I use the above select command and try to create the update string it either does nothing or errors out on the page:

IE:
UPDATE DATABASE2.dbo.[Tracking] A SET [UserKey] = @UserKey, [ItemKey] = @ItemKey, [TicketID] = @TicketID, [StatusID] = @StatusID, [Notes] = @Notes, [CarrierID] = @CarrierID, [TrackingNum] = @TrackingNum, [ReasonID] = @ReasonID WHERE [TrackID] = @original_TrackID

I'm relatively new to this and have no clue where to go from here since most examples online use a small single database that I'm having trouble translating over to what I'm trying to accomplish. Personally, I'd prefer to have this done in a code behind but I'll take whatever I can get at this point.

Full code:

I'll eventually want to add some kind of control to insert new rows into the second database and remove rows if needed.

FYI, DATABASE.dbo.* is read only where DATABASE2.dbo.* is the one I need to write to.

Thanks.

<wild guess>
Last I remember a view is not updateable when there are more than two tables in a JOIN.

Well, that would be a problem.

Is there a way in a code behind to use a separate select and update to modify the data from table to table instead of directly updating the view?

for the following reason:

You're correct. I figured out how to build the update query automatically from SSMS and using the SELECT to join the tables I needed to create my view so I didnt have the 3 table uneditable view in my update command. Many thanks.
