suppressing Submit command with a Delete button

I have a Delete button in my datagrid. I'm attempting to add some code
confirming whether the user wishes to really delete the item or not.

The confirm pops up, but I cannot suppress the submission when selecting
Cancel.

Heres what I have so far:

' adding the javascript call to the button:
Private Sub dgItem_ItemCreated(ByVal sender As Object, ByVal e As
System.Web.UI.WebControls.DataGridItemEventArgs) Handles dgItem.ItemCreated

If e.Item.ItemType = ListItemType.Item OrElse e.Item.ItemType =
ListItemType.AlternatingItem Then

Dim objDeleteButton As Button = CType(e.Item.Cells(1).Controls(0), Button)

objDeleteButton.CssClass = "inputbutton"

objDeleteButton.Attributes.Add("onClick", "confirmDeleteItem();")

End If

End Sub

' client side code in javascript

function confirmDeleteItem()

{

if (confirm("Are you sure you wish to delete this item?"))

{

return true;

}

else

{

return false;

}

}

any help is appreciated. thank you.Sounds like you have validation controls on there, which causes the runtime
to emit yet another onClick handler which submits the form. Try using an
<input type="button"> instead of an <asp:button> control, and if you need
validation just script in the validation call (and, as always, make sure you
explicitly validate on the server, as client side validation is easy to
foil).

Chris:

Thanks for the reply. I am struggling with this.

If I take your approach it seems I dont have the ability to wire it to the
DeleteCommand event. This means I have to access the DataKey for the row
through the client, which I dont want to do. I could be wrong on this
though.

All I really want to do is have a DeleteCommand button that performs a
delete with a confirmation prior to deletion. My code does not have any
other validators on the page. There is another button on the page, but
performs a completely unrelated task.

Aha - that's a special case I hadn't considered.

Suppressing the URL in a asp.net app

Hi,

I've seen many Internet sites that suppress the URL or show the same URL all
the time your moving around different pages. You'll only see the real page
with it's path in the statusbar way down on the page.

How is that done in asp.net?

I have an example on this, in sweden, stockholm where I live we have a
wellknown kindergarten for older men (warehouse shop) named Clas Ohlson

http://www.clasohlson.se/

You'll also have them on a flaglink in finnish, norwegian and english
language just above the statusbar. So that you see what I mean.

Any ideas?

TIA

Kenneth PThe above link (http://www.clasohlson.se/) is using a frameset. The
address bar isn't updated since you're navigating within a frame of the
page frameset.

Since HTML Framesets are a client side technology, this approach would
work the exact same in ASP.NET.

More info on frames here:

Hi

They are using frames. Just look at the main page "View -> Sourece" and you
will see that page have some frame.
With right click on page you'll see that page has url. Click on top and also
on bottom to see that the page url is different.
Also take a look on frame stuff to undestand clearly what is happening.
There is no trick made in asp.net in that page.

Cheers.

That has nothing to do with asp.net or any other server-side technology,
it is client-side html.
The trick is to use a frameset as your first page. The URL shown is the url of that
frameset definition, the rest of the site works within that frameset.

For that site: use "View | Source" from the menu and scroll down to below the
<NOSCRIPT> section. (strange, a noscript section with embedded javascript...)

Hi jongalloway,

Hmmm...

Have you seen the same technology on pages without frames?
