Passing custom parameters to a web resource in v9

Posted on by Community Member

I'm running Dynamics 365 v9, and can't pass parameters to a web resource embedded in a form. I've tried the methods shown in these links:

https://msdn.microsoft.com/en-us/library/gg327945.aspx

I have added "test=testValue1" to the custom parameter box in the web resource, but, when I call "GetGlobalContext().getQueryStringParameters()" or "location.search()", my result contains only the appId parameter from the parent windows URL. Am I misunderstanding something?

Hi Sheltam,

Based on Microsoft documentation there is no getQueryStringParameters anymore.

The getQueryStringParameters has been replaced by formContext.data.attributes:

The formContext.data.attributes API will make retrieval of non-entity bound data consistent across entity forms, metadata-driven dialogs, and task-based flows. The data will be a combination of custom values sent using the query string and what was specified in the parameters in the openForm method.

Hope this helps.

Hey Aric,

Thanks for the response. I'm not sure how to get the formContext from a Web Resource. I know on normal form fields you can check a box to pass in the execution context, and then retrieve the formContext from that, but there is no similar capability on a Web Resource.

Hi,

For html webresource you should be able to use global context

docs.microsoft.com/.../getglobalcontext-clientglobalcontext.js.aspx

Thanks Mahender and Preeti,

That got me to where I needed to be. After getting the GlobalContext I was able to call getQueryStringParameters() and bring back the custom parameter. I'll have to check on whether getQueryStringParameters is being deprecated as Aric suggested.
