Hi All,

I want to Hide some fields based on some condition. for example, I have one field type of lookup and in that I have a lookup table, and I am selecting one option from there suppose 'Tangible' so based on Tangible option I want to hide some other fields and show some fields. I tried below code, but it didn't work.

>>Below is screen print for the Lookup field:

>>Here hideshow is variable of type boolean.

// local procedure hideshowfield(): Boolean

// begin

// hideshow := true;

// if Rec."FA Class Code" = 'HOUSE' then begin

// hideshow := false;

// exit(hideshow);

// end else begin

// hideshow := true;

// exit(hideshow);

// end;

modify("FA Class Code")

{

Caption = 'Asset Type';

trigger OnAfterValidate()

begin

//hideshowfield();

end;

}

field("Description 2"; Rec."Description 2")

{

ApplicationArea = all;

//Visible = hideshow;

}

Can anyone give me a suggestion what is missing here? or any other way to achieve this?

Thank You.

Hello Inkey Solutions,

Unfortunately, it is not possible to show and hide fields dynamically. But where it works is with groups. I have no idea why it works for groups and not for fields. So you have to put the fields you want to show and hide in a group.

You can try it yourself with the following code:

page 50153 "TestPage" { ApplicationArea = All; Caption = 'TestPage'; PageType = Card; layout { area(content) { group(General) { field(OptionField; OptionField) { trigger OnValidate() begin if OptionField = OptionField::Option3 then isVisible := false else isVisible := true; end; } field(TextField1; TextField1){ Visible = isVisible; } group("HideGroup") { ShowCaption = false; Visible = isVisible; field(TextField2; TextField2){} } } } } trigger OnOpenPage() begin isVisible := true; end; var OptionField: Option Option1, Option2, Option3; TextField1, TextField2: Text[100]; [InDataSet] isVisible: Boolean; }

Hi,

Please declare your variable like below

var

[InDataSet]

hideshow :boolean;

and use that variable wherever you want.

Put your code in Text format not in Image.
