How to show multiple selected items on custom page?

[Divya_R]

Hi Team,

I am trying to get selected records from main grid in model-driven app to show on custom page.

On Microsoft site, there is code to pass single record through javascript. I am able to pass guids of multiple items but can't find a way to use them in custom page App.OnStart property.

function run(selectedItems)
{
    let selectedItem = selectedItems[0];

    if (selectedItem) {     
        let pageInput = {
            pageType: "custom",
            name: "<logical page name>",
            entityName: selectedItem.TypeName,
            recordId: selectedItem.Id,
        };
        let navigationOptions = {
            target: 1
        };
        Xrm.Navigation.navigateTo(pageInput, navigationOptions)
            .then(
                function () {
                    // Handle success
                }
            ).catch(
                function (error) {
                    // Handle error
                }
            );
    }
}

Below code is used to get a single record but if I am sending ids of multiple records, how can I use them with param?

App.OnStart=Set(RecordItem, 
    If(IsBlank(Param("recordId")),
        First(<entity>),
        LookUp(<entity>, <entityIdField> = GUID(Param("recordId"))))
    )

Any help is greatly appreciated!!

Thanks!
