Title: refresh child-source when selected row changes
Post by: bergsj on September 22, 2009, 02:28:33 AM

Hi,
I have a browse with a source as child beneath it. When the selection of the browse changes I woulk like the source to be refreshed (ajax-style). Can this be done?

Certainly.
If the source procedure has the setting
"Generate Ajax Div"
turned on, then it should be updated automatically when the browse row changes.

Cheers
Bruce

Bruce,
Indeed when I put only text inside this source, it worked fine. I tested with:
packet = 'ID =' & p_web.GSV('webOrd:Identifier')

But when I try this, the button is not updated:
packet = '<div id="buttondiv" class="buttondiv"><button type="button" name="btnCarrierInfo" id="btnCarrierInfo" value="CarrierInfo" class="MainButton" onclick="window.open(''frmOrderCarrierInfo?ORD__Identifier=' & p_web.GSV('webOrd:Identifier') & '&PressedButton=change_btn'');">Carrier Info [' & p_web.GSV('webOrd:Identifier') & ']</button></div>'

Any idea?

In almost all cases the problem is that the stuff you are hand-coding is not xHtml complient. The most common cause of this is "unclosed" tags, for example using <br> when you should have <br></br> - or <br /> for short.

You're ok on this front - at least overtly.

The second issue is that you are using a variable in the line which contains characters that are non-xhtml complaint.  To handle this you can make use of the _jsok method. for example;

packet = '<div id="buttondiv" class="buttondiv"><button type="button" name="btnCarrierInfo" id="btnCarrierInfo" value="CarrierInfo" class="MainButton" onclick="window.open(''frmOrderCarrierInfo?ORD__Identifier=' & p_web._jsok(p_web.GSV('webOrd:Identifier')) & '&PressedButton=change_btn'');">Carrier Info [' & p_web,_jsok(p_web.GSV('webOrd:Identifier')) & ']</button></div>'

Cheers

Bruce,
I did exactly that, but still nothing changes until I refresh the page myself.

Any clues?

It works with a simple string, but not with your button.
so maybe you need to build up your string one bit at a time
until you see why it stops working?
