GridView Enable Editing and Deleting Missing

N_B · February 13th, 2017, 05:50 PM

On page 444, #8 after dragging the Genre table into the cpMainContent area, when the Smart Tasks panel comes up, it does not show check boxes for "Enable Editing" and "Enable Deleting".

IMPORTANT: I'm using Oracle here and not SQL Server. And the user I connect to the database with has SELECT/INSERT/UPDATE/DELETE privileges on the table.

What could be the reason why the options for Edit and Delete do not show up?

Thanks,
Neil

Hi Neil,

Maybe your table doesn't have a primary key?

I don't use Oracle so I am not sure to what extend this scenario is supported or what it takes to make it work.

It does have a primary key.

What SQL does it create for you?

Like I said, not using Oracle, so I can't help you much further than asking some obvious questions ;-)

Cheers,

The SqlDataSource looks like this after I drag the table:

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:FG01 %>" ProviderName="<%$ ConnectionStrings:FG01.ProviderName %>" SelectCommand="SELECT "ID", "NAME", "SORTORDER" FROM "GENRE""></asp:SqlDataSource>

Yeah, that's what I expected. The missing edit and delete statements indicate that the source doesn't support it, which could mean the lack of keys, support for it in Oracle, or something else.

So I would have to manually set the UpdateCommand, DeleteCommand, and InsertCommand properties myself? As well as the UpdateParameters, DeleteParameters, and InsertParameters as shown on page 446? Bummer.

Anyone here use Oracle and know how to resolve this without doing it manually?

So I'm in Chapter 13 where it deals with a lot of the VS dialog boxes for database access and query building and column formatting. But it just plain does not work with Oracle? This can't be, can it?? I know Microsoft wants everyone to use their database, but they can't be so stupid as to not allow this to work with Oracle, right? I mean Oracle is a HUGELY popular enterprise database.

Someone here HAS to be using Oracle, no??? Am I missing something?

ON page 461, VS produces this for me:

SELECT [ID], [TITLE], [AUTHORIZED], [CREATEDATETIME] FROM [REVIEW] WHERE ([GENREID] = ?)

This does not work in Oracle. It should be:

SELECT ID, TITLE, AUTHORIZED, CREATEDATETIME FROM REVIEW WHERE (GENREID = :GENREID)

And it won't produce the <asp:ControlParameter> code. I guess that's the reason for the question mark?

You may need to install the ODT: Oracle Developer Tools: http://www.oracle.com/technetwork/de...iew/index.html

With those installed, it seems you can do stuff like this: http://www.oracle.com/webfolder/tech...SPNetApps.html which is pretty much what my book is doing.
