User prompt handling

[Thrud]

I have a button (runat=server) with some VB code attached
to its on click event which does data updates.

I now want to add a warning to the user prompting them
whether they really want to perform the update. If they
say Ok then the update proceeds, otherwise it is cancelled.

How is the best way to do this? As far as I see the only
way to get the prompt is to use the JScript Confirm
function but to use this I need to turn off the
runat=server flag which makes the button disappear.

Any help would be much appreciated, Thrud

couple ways...
First is a simple CLIENT-SIDE confirm attached to the button.
The other is what I have done. Two buttons. The first simply posts back and
"un-hides" a confirm button while it "hides" the save button. The confirm
button has the actual code to save the info to the DB, not the save button.

Use:

MyButton.Attributes.Add("onClick", "return confirm('Are you sure you want to
continue with this update?')")

Hope this helps,

If you don't mind spending a little money, I found this handy, Submit

Basically a custom .NET control where you assign the control to confirm and
a message, and it pops up the message just like the Javascript type. You can
set the message dynamically as well, and use \n to make breaks, just like
Javascript.

Add this to your button in code behind:

btn.Attributes["onClick"] = "alert('Something');"

Or "confirm" - same thing, but use return.

Regards.

Thanks All, especially Munsifali,

MyButton.Attributes.Add("onClick", "return confirm('Are
you sure you want to
continue with this update?')")

works exactly how I want.
