Dynamically make page fields visible based on the value of another field

Posted on by Ghetz 3,011

Quick question, why this doesn't work?? No matter how many times I change MyOption field's value, FieldH,V and F are never visible. BC 21.1 environment.

pageextension 50004 "Custom Item card" extends "Item Card"
{
    layout
    {
        addafter(VariantMandatoryDefaultNo)
        {
           
            field(MyOption; Rec.MyOption)  //This is an Option type field in my Item table
            {
                ApplicationArea = Basic, Suite;
            }
            field("FieldH"; Rec."FieldH")
            {
                ApplicationArea = Basic, Suite;
                Visible = Rec.MyOption= Rec.MyOption::"1 Eje"; //Tried with a specific Option value, but still not working
            }
            field("FieldV"; Rec."FieldV")
            {
                ApplicationArea = Basic, Suite;
                Visible = Rec.MyOption> 1;    //This is what I actually need to achieve
            }
            field("FieldF"; Rec."FieldF")
            {
                ApplicationArea = Basic, Suite;
                Visible = Rec.MyOption> 2;
            }
        }
    }
}
Curious fact, Editable = Rec.MyOption> 1; works perfectly, so browser wise, it shouldn't be a problem, as I guess all this has JS on code in the background

    Hello Ghetz,

    You need to put all the fields inside the group to which you want to hide or unhide and give visibility property to the group.

    Actually visibility conditions are different for each field. If this is the case, I will need to create one group per field. Was wondering if there was any way to avoid that.

    Yes, you have to put each and every field in a separate group. Because this is the only way to Dynamically Hide and Unhide the field.

                field("FieldV"; Rec."FieldV")
                {
                    ApplicationArea = Basic, Suite;
                    Visible = VisibleControl2;    //This is what I actually need to achieve
                }
                field("FieldF"; Rec."FieldF")
                {
                    ApplicationArea = Basic, Suite;
                    Visible = VisibleControl3;
                }
            }
        }

        trigger OnAfterGetRecord()
        begin
            VisibleControl2 := Rec.MyOption > 1;
            VisibleControl := Rec.MyOption = Rec.MyOption::"1 Eje";
            VisibleControl3 :=  Rec.MyOption > 2;
        end;

        var
            VisibleControl: Boolean;
            VisibleControl2: Boolean;
            VisibleControl3: Boolean;
    }

    Hi

    you must value your control variables in the OnAfterGetRecord() trigger of the page
