condition on column in grid

you have written correct code only. For editable grids, it doesn't show up a * mark on the column. But if you try to submit without a value then the form will not be submitted.

Here is the same code I tried and its working for me.

= a!formLayout(
  label: "Lorem Ipsum",
  instructions: "Lorem Ipsum",
  firstColumnContents: {
    a!gridLayout(
      headerCells: {
        a!gridLayoutHeaderCell(
          "Col1"
        ),
        a!gridLayoutHeaderCell(
          "Col2"
        ),
        a!gridLayoutHeaderCell(
          "Col2"
        )
      },
      rows: a!gridRowLayout(
        contents: {
          a!textField(
            label: "Application Name" & ri!indexRoles,
            value: ri!itemsRoles[ri!indexRoles].applicationName,
            saveInto: ri!itemsRoles[ri!indexRoles].applicationName,
            required: false,
            readOnly: true
          ),
          a!dropdownField(
            label: "Approved",
            labelPosition: "ABOVE",
            placeholderLabel: "--- Select a Value ---",
            choiceLabels: {
              "Yes",
              "No"
            },
            choiceValues: {
              "Yes",
              "No"
            },
            value: ri!itemsRoles[ri!indexRoles].approved,
            saveInto: ri!itemsRoles[ri!indexRoles].approved,
            required: if(
              ri!rejectApplicationsYN = "Return to Customer",
              true(),
              false()
            ),
            validations: {}
          ),
          a!imageField(
            label: "delete " & ri!indexRoles,
            images: a!documentImage(
              document: a!iconIndicator(
                "REMOVE"
              ),
              altText: "Remove",
              caption: "Remove " & ri!itemsRoles[ri!indexRoles].applicationName,
              link: a!dynamicLink(
                value: ri!indexRoles,
                saveInto: {
                  a!save(
                    ri!itemsRoles,
                    remove(
                      ri!itemsRoles,
                      save!value
                    )
                  ),
                  /* When modifying the size of the array used in a!applyComponents,  */
                  /* make the same change in the "token" array variable               */
                  a!save(
                    ri!itemsTokenRoles,
                    remove(
                      ri!itemsTokenRoles,
                      save!value
                    )
                  )
                }
              )
            ),
            size: "ICON"
          )
        }
      )
    )
  },
  secondColumnContents: {
    /* Add components here for a two-column form */
    
  },
  buttons: a!buttonLayout(
    primaryButtons: {
      a!buttonWidgetSubmit(
        label: "Submit",
        style: "PRIMARY",
        saveInto: {}
      )
    },
    secondaryButtons: {
      a!buttonWidgetSubmit(
        label: "Cancel",
        style: "NORMAL",
        value: true,
        saveInto: ri!cancel,
        skipValidation: true
      )
    }
  ),
  validations: {}
)

output:

Hi sswilliams ,

May i know the type of button you used, I mean a "Submit" or "Normal" button, If you are using "a!buttonWidget" then you should passed the Validate flag, eg

a!buttonWidget(
   validate:true(),
   label: "Submit",
   style: "PRIMARY",
   saveInto: {}
)

check for the following things
1- check the type of ri!rejectApplicationsYN, it should be text
2- use a submit button like a!buttonWidgetSubmit() to show error


*remove the if statement as it is redundant here

let me know if this doesn't work out
