sdaram · ‎Mar 09, 2017

Hi Everyone My Requirement is bit different

I want to Pass Parameters from Webpage to Thingworx Mashup. To Explain In detail

I have a webpage designed by ASP.NET here i am integrating Thingworx Mashup in Iframe control.

So my Webpage have Asp.control and Thingworx mashup.

In below screen i have integrated Thingworx mash up in iframe. rest all controls are asp.net controls

When i select drop down (Asp.net Control ) the selected value of drop down should pass to thingworx mashup. and mashup should respond accordingly.

The received values from Asp.net webpages i should use in Thingworx Mashup.

I need to know the process how we can pass values from Asp.net web page thingworx Mashup.

Looking for Positive Response.

You can pass the parameters over the url.

so let's say you have a mashup with a mashup parameter named param1

you can set that by using <server>/Thingworx/Mashups/NameOfYourMashup&param1=value (note that sometimes you might be using ? for the first switch for example if you are using an appkey)

Hi Pai Chung,

I have Done Following Steps for above my use case

1) I have created Mashup parameter named it as "myparam"

2) I have Created a Service in Thingworx Mashup "GetDataTableEntryByKey" and giving input as Mashup parameter (myparam)

I bound my service by accepting input as Masup parameter(myparam) --->Key

3) I am calling My Mash up in iframe like this

</iframe>

http://localhost:8080/Thingworx/Mashups/testabc? appKey=0f4b4662-7d09-46c3-a766-bbbcfa73ad99&x-thingworx-session=true&myparam=1

In the above URL.

testabc--Mashup Name

myparam--Mashup Parameter (value is '1')

The web page looks like this

So Here I need Some Clarification and Help.

in above Mashup myparm (mashup parameter) there is no input binding. The Output of myparm is input of service.

Queries

1) How to assign value which i am passing in URL to mashup parameter.

2) Is there any other way to use "Session parameter" to get this approach.

'

looking for positive response.

Thanks & Regards

&myparam=1 is how the value is assigned to the parameter. you can try binding the myparam from the mashup to a Value display on the mashup to check.

then The service itself should run based on myparamvaluechanged event which comes with the mashup parameter

I don't see a need to write to the session, if you needed to do that though you would wire from the mashup param to the session or use a service to set it server side.
