Enhanced Search Widget for FlexViewer 2.1

[RobertScheitlin__GISP]

All Here is my next widget in the FlexViewer 2.1 series

Special thanks to Erwan Caradec for contributing to this code.

The Enhanced Search Widget extends the standard search widget with a floating data grid and a new spatial query w/buffering.

Simon,

   have you looked at the sum capability of the eSearch datagrid?

<field name="Length_" numberformat="2|,|." sum="true" sumlabel="Total Length: " gridfield="true"/>

Thank you so very much!! I have not tried it yet but I am excited to!!! I also wanted to let you know that your widgets alone have enabled us to bring GIS to over 100 users within our organization, thank you very much and have a great thanksgiving.

Hi Robert,
I wondered if there is a way to append to selection set using the enhanced search widget?  If I select a subdivision boundary using the point select tool in the graphical search tools and then use the spatial search tools and select the parcels that are entirely contained within the subdivision boundary, I get all but three parcels.  Obviously, our subdivision boundary needs to be corrected, but in the meantime, I would like to be able to add those three parcels to the selection set so I can export all of them to a csv from your datagrid table.
Thanks,
Caitlin

Caitlin,

     Currently No and it is not going to make it into the 2.5 version of the widget either.

Ken,

   If you bring up your REST Service directory for this layer does the ACREAGEDOM field show the coded values like this:

Surf_Type (Type: esriFieldTypeSmallInteger, Alias: Surface Type, Domain: Coded Values: [1: Tar and Gravel], [2: Asphalt], [3: Chert], ...2 more... )

[KenCarrier]

One thing I failed to mention, the domains exist on subtypes not on the default field, could that be causing the issue? I reviewed the SearchWidget.mxml code, I am not a Flex developer but I did not see any error trapping for subtypes within the code, although I might have missed it.

Ken,

   Ken it could be subtypes as I don't use those and probably have not accounted for them in the code. Is your data with subtypes public?

[KenCarrier]

Robert,

I am not sure what you mean by public, it is a public facing website.

I tried setting up the domain on the default field as well as the subtype but still no luck.

I basically have 3 subtypes pertaining to the type of land i.e.(RESIDENTIAL,COMMERICIAL,AGRICULTURAL). Within each subtype I use a domain, it is the same domain. I tried setting the domain on the field instead of just the subtype but still get the same error. I am currently developing on a local machine. So the functionality I mentioned is not public facing yet.

I know you are busy and this might only pertain to me currently, but do you think adding this functionality might help others within the community?

[RobertScheitlin__GISP]

Ken,

   I am sure it would be benificial to others and I am working on the version 2.5 release so this is good timing. Is the REST service available for me to test against (the way you originally had it with the domain on the subtype)?

[KenCarrier]

Robert,

I have reverted the rest endpoint back to how it was originally with the domains on the subtypes.

Here is the rest url

Thank you taking the time to look at this!
