Found good info about how to add extra items above and beyond those data bound in ASP.NET.

Delete confirmation dialogs with ASP.NET

Tue, 04 Apr 2006 04:01:40 GMT

Quote:

DetailsView and FormView controls support delete operations and delegate the execution to the underlying data source control. If the data source control is configured to execute the delete operation, all works fine, otherwise an exception is thrown.
The DetailsView generates command buttons automatically and doesn't expose them directly to page code. How can you add a bit of Javascript code to ask for confirmation? Here's the code...

SqlDataSource and identity columns

Mon, 03 Apr 2006 17:08:26 GMT

Everybody seems to think you need a stored procedure to get back the identity of a row inserted using a SqlDataSource. You don't. Instead, you can just tack on a select to the end of the insert and use that to get back an output parameter -- that's available in the inserted event for the SqlDataSource.

For example, in the insert do this:

InsertCommand="INSERT INTO [Customer] ([Name]) VALUES (@Name); SELECT @NewID = @@Identity"

Then add an additional parameter to the <InsertParameters>:

<asp:Parameter Name="Name" Type="String" />

<asp:Parameter Direction=Output Name="NewId" Size=4 Type=Int16 />

</InsertParameters>

Then you can check for the ID of the returned item here:

protected void SqlDataSource1_Inserted(object sender, SqlDataSourceStatusEventArgs e)

{

object newId = e.Command.Parameters["@NewId"].Value;

}

Thanks to Fredrik Normén for this!

Someday I'm going to do some work with the Windows Desktop Search APIs. It's great to have such an engine available to build things on top of.

How to put a DIV over a SELECT in IE?

Never heard of this bug before -- until it bit me when I was building tooltips for a DHTML menu system. Looks like there's a workaround: How to put a DIV over a SELECT in IE?

Visual Sidekick (Visual Studio Add-in)

Wed, 22 Dec 2004 17:56:46 GMT

For the past few weeks I've be trying out Visual Sidekick, an add-in for Visual Studio. It makes it really easy to quickly navigate around a fairly large project quickly. The trial was about to run out and I decided it's really worth it so I bought a copy. They've got the UI 98% right and that means it's not only concenptually a good idea but in practice it really speeds things up.

Nice job.

Syntaxia Technologies - Home of the Visual Sidekick Add-in
Developers constantly jump around between classes, methods and files. They do this when writing new code, debugging existing code and maintaining old code. Code navigation is a fundamental development task, and it is surprising that even the modern IDE's don't do a great job in helping developers navigate their code quickly.
There's got to be a better way... and there is!
