Inside a gridview i have a button to delete a record (button 3). There is a ConfirmButtonExtender to prevent a administator from deleting the wrong record.
This works fine, but the page gives an error (IE6 in the statusbar). Also some TextBoxWatermarkExtenders placed after the gridview only work after a postback. When I take out the ConfirmButtonExtender it works fine. I can't place the ConfirmButtonExtender outside the gridview because it doesn;t find button3 than.
Anyone? By the way: the ConfirmButtonExtender does work like it's supposed to!

Yours' is in a repeater......
Or should I paste the complete code?
OK, here is the complete code:

If all you want is for a confirm box to popup with a message, you can try just using the OnClientClick of the button itself. It would look like
onclientclick="return confirm('Zeker weten?')"
so your button will be...
<asp:Button ID="Button3" runat="server" Style="background-attachment: fixed; background-color: transparent;
background-image: url(http://blabla.gif); background-repeat:no-repeat ; border-top-width: thin; border-left-width: thin; border-left-color: moccasin; border-bottom-width: thin; border-bottom-color: moccasin; border-top-color: moccasin; border-right-width: thin; border-right-color: moccasin;"
Width="32px" tooltip="Verwijder WV (definitief!!!!!)" CommandArgument='<%# eval("Kop1AlgVpNummer")%>' Height="30px" OnCommand="Button3_Command" BorderColor="#FFE0C0" BorderStyle="None"onclientclick="return confirm('Zeker weten?')" />
I do this all the time in gridview delete buttons. It works just like the confirm button.

Good tip, I'll try this tomorrow. Maybe i didn't think of this because of my limited knowledge of javascript...
This works fine, the error is gone.
You could, however, ask yourself why the error is produced...
