Popup 3.0 - hide field if value=null

philippschnetzer — Thu, 27 Sep 2012 16:21:23 GMT

using the latest flaxviewer 3.0. I would like my popups to hide fields if they do not contain a value. Can this be done easily? I'm assuming it will need to happen in the mxml and not the xml, correct? Thanks

Yes, you need to create a custom PopUpRendererSkin. Try making this change to line 163 of PopUpRendererSkin.mxml:

if (fieldInfo.visible && formattedAttributes[fieldInfo.fieldName])

PopUpRendererSkin.mxml is in the skins folder inside the API's zip file.

Is it possible to do this if you are using the Flex Viewer 3.0 in compiled mode using xml?

I'm new to Flex and am currently customizing widgets in I believe the compiled mode.

How difficult would it be to figure out the option you mentioned previously and what software is best to use when editing the code?

Thanks,

You'll need to recompile the Viewer to make any changes to mxml source files.

Hi Dasa,

was wondering if there is anything else one needs to do to make this happen?

I have made the change to my PopUpRenderSkin.mxml, but I still get fields in my popup that have null values:

Rhett,

It looks like all the fields in your screenshot have values.

Whoops, clicked on the wrong well.

However, after re-boot, re-clear everything, it seems to be working now.

Thanks for the help,

Hi Dasa,

In several of my data sets, I often end up with a space in the "empty" cells. Is there a way to modify this so that a single space is also filtered out as well as blanks and Nulls?

Thanks again,

Try:

if (fieldInfo.visible && formattedAttributes[fieldInfo.fieldName] && formattedAttributes[fieldInfo.fieldName] != " ")

Excellent, works like a charm.

Was so close, but was missing the formattedAttributes part.

Thanks again, this is slick,
