Double click not working

tshad

I have been working with setting my drop boxes to allow double clicking to
select an item.

It worked fine until I made some changes. I then stripped the page down to
the bare essentials to find out why it quit working. I found that if I
didn't have a linkbutton, it quit working?????????

If I changed the linkbutton to a regular button, it quit working.

Here is the page:

</form>

<p> </p>
</body>
</html>
************************************************** ***********************

This page works fine. Loads the Listbox fine. Sets the Listbox to have the
ondblClick event, which works great (it does post back and the trace.warn
displays fine.

But if I take out the line:

<asp:linkButton id="NewRecord" Text="New" runat="server" />

It quits working.

If I change it to:

<asp:Button id="NewRecord" Text="New" runat="server" />

It quits working (the button works, but the dblClick does not).

These objects are not connected, why would it have an effect?

I need to find out what is happening as 2 of my main pages are now not
working correctly.

Thanks,

Tom

The interesting thing is you can just put a nothing link (no id, test,
event) anywhere on the page and it will cause the page to work. But the
linkbutton must be visible.

I added the following to the 2 pages that quit working and all of a sudden
they worked fine.

<asp:linkButton runat="server" />

This makes no sense !!!!!

It works fine as a bandaid, but not a proper solution.

makes perfect sense.

you wrote client code that calls __doPostBack(), the routine used by
autopostback (javascript) controls. you need an autopostback control on the
page for this to be available. a linkbutton works, but a standard asp:button
is actually a submit button, and does not require javascript to postback. if
a control is maked invisible, its not rendered, so it just like its not on
the page.

I'd never heard that one before.

I don't think any of the other places where it shows how to set up double
clicking do they talk about needing another control to make it work.

I assumed that the double click event is self contained to the control it is
connected to as well as Javascript (not asp.net). What else could I use on
the page to make it work other than a link button.

The invisible problem does make sense.

the code you add to the dblclick is

"__doPostBack('LbxSender','')"

for the client javascript function __doPostBack to exist, you need an
autopostback control on the page. if you just need a postback try:

"document.forms[0].submit();"
