Embedded canvas App + Get Lookup Value and change display mode of a field

Hi All,


I have an embedded canvas app on the CRM Form. I need to get the lookup value of a field.


The relationship is as follows -

"Entity A has a lookup of Entity B on it"

"Entity B has a lookup of Entity C on it"


The embedded canvas app is on Entity A
I need to get the "Entity C" value inside the embedded canvas app.

I tried the below things -

1) Set the below formula on the "onvisible" property of the form screen

2) Placed a label on the form and set it text property to First(EntityBRecord).Name 

But the label does not display anything 😞


Moreover I need to check if the "Entity C" lookup on "Entity B"  has a value, if yes, then make the display mode of the field "Disabled" otherwise "Editable".


formula pseudocode for the datacardvalue-

If('Entity C contains data',Parent.DisplayMode.Disabled, Parent.DisplayMode)


Kindly provide any guideliness/syntax on how to achieve this.


Any help would be appreciated.

Can you try this for the OnVisible property of the form screen? 

Set(gblContextualRecord, LookUp(EntityA, ID = [@ModelDrivenFormIntegration].Item.ID);
ClearCollect(EntityBRecord, LookUp(EntityB, ID = gblContextualRecord.LookupOfEntityBonEntityAID))

And you can then use this to check if EntityC has data:

If(IsBlank(First(EntityBRecord).EntityC.ID), DisplayMode.Disabled, Parent.DisplayMode)

Let me know if this works.
