Custom Page Param via URL

[MKeppel]

I am trying to pass a param to a "Custom Page", via URL.

While this works with a Canvas App, it doesn't seem to work with Custom Page.

On App Start

Set(varparam, Param("testparam"));

Then URL

main.aspx?appid=xxxxxx&pagetype=custom&name=cns_custompagetest_c494c&testparam=test

I get the follow type of error

Is there a why to pass a param to a custom page via URL, if so what is the correct method, as the method which works for canvas apps does not seem to work for custom pages

----------------------

Found a solution..

within the custom page.

On start

Set(
  RecordItem,
  If(
    IsBlank(Param("recordId")),
    Blank(),
    LookUp(
      entity,
      recordid = GUID(Param("recordId"))
    )
  )
);

With URL of

main.aspx?appid=xxxxxx&pagetype=custom&name=cns_custompagetest_c494c&etn=ENTITYNAME&id=GUID

Hi @MKeppel & @v-bofeng-msft 

Thanks for this post. it helped me half the way. Maybe you can help me with the other half.
I would like call/open a custom page inside a model-driven app from an URL.
But instead of passing a guid/id to the custom page, I need to pass a phonenumber via URL Parameter.
Example: https://org..../main.aspx?appid=appid&pagetype=custom&name=custompagename&phonenumber=+41789996622

I've tried many different things but failed. I can pass the "id" parameter, but it must be a guid. Otherwise I receive an error.
If I use the URL above with the parameter "phonenumber" or "data", the custom page opens, but the "param()" function inside the custom app does not return a value.

Any idea, how I get the phonenumber to the custom page?

Kind regards

Tobi

I haven't done much more testing, to see if it is possible to pass anything but a entity GUID. 

If the phone number part of the record you are passing from. I would still pass the whole record using the GUID as per the original code then just retrieve it with

RecordItem.phonnumber

Good, it is useful for me.

Have you happened to find a solution to pass the values other than the GUID? I can't find what the GUID would be for the item in my DataVerse table I am trying to pass the Title of from one page to another.
