Hi,

You need to use record link inside your linkfield function in the record. Attached sample code , summary view should be configured under views tab in records.

a!gridColumn(
    label: "Name",
    sortField: 'recordType!testrecord.field',
    value: a!linkField(
      links: {
        a!recordLink(
          label: fv!row[recordtype!field],
          recordType: 'recordType!testrecord',
          identifier: fv!identifier
        )
      }
    )
  ),

but the data from cdt not record Type

Did you try to attend the Appian online trainings. Your code violates some of the basic principles covered in these trainings.
