Opening a related table from tap event.

Question

I have a simple Edit screen called DE_Client which is based on a SQL Table (not a view).
I have a browse screen based on a SQL View of the same table and have related the two elements together.
Using the standard tap event option I have chosen to open the DE_Client screen from the view and expected it would open the related record, but it looks like its now going to be that simple ?
I see that if I use the above and tap the item nothing happens so I expected I would have to add an option to the bottom item, I see that I have an Option (New PATIENT_TABLE) but this just opens a new diaglogue for entry.
Thanks in advance for any assistance you can give on this.

Answer 1

Make the edit screen accept the Id or primary key as a parameter, then deal with retrieving the PATIENT_TABLE record in the screen's _created event.
or
Use 'Write my own method' to call 'myapp.showScreen(...'
// retrieve 'patientTable' before showing screen
myapp.showAddEditPATIENT_TABLE(patientTable) // or
myapp.showScreen("AddEditPATIENT_TABLE", null, {
beforeShown: ...
But writing code and doing it this way is not necessary, you can just wire it up in the designer. Less code is better most times. Code could be more efficient though.
Create a custom query on "PATIENT_TABLE" in the server project. Add parameter(s) that you will use for value(s) to pass from a view row (perhaps Id , or the primary key). Filter by the parameters and set the query to return 'Single' not 'Multiple'.
In the browse screen design do "Add Data Item..." and "Query", choose your new custom "PATIENT_TABLE" query. Ok.
Bind the query parameter(s) to the corresponding value(s) in the selectedItem of the visual collection of the 'view'.
Now when setting up the item_tap you have a "PATIENT_TABLE" to pass in as the parameter.
