TdxBackendCustomParameter.Visible Property

Specifies if the parameter editor is visible in the Report or Dashboard UI.

Declaration

property Visible: Boolean read; write; default True;

Property Value

Type	Default	Description
Boolean	True	True if the parameter editor is visible in the end-user UI; otherwise, False.

Remarks

Use the Visible property to display or hide the parameter in the end-user UI.

This property corresponds to the Visible combo box in the Report Designer or the Visible option in the Dashboard Designer:

Report

Dashboard

Note

The Visible property affects only parameter editor visibility in the end-user UI. Selected parameter values still apply to the report / dashboard data source.

Code Examples

The following code snippets hide the parameter from the UI.

Note

The Visible property is common to report and dashboard parameters. These examples perform the same operation but use component-specific APIs.

Hide the Report Parameter

Delphi

uses
  dxReport.Control;   // Declares the TdxReportControl class

procedure TForm1.cxButton1Click(Sender: TObject);
begin
  dxReportControl1.Parameters['countryParameter'].Visible := False;
end;

C++

#include "dxReport.Control.hpp"   // Declares the TdxReportControl class

// Add the following linker directives to the corresponding CPP source file:
#pragma link "dxReport.Control"   // Required to use dxReport.Control.hpp declarations

void __fastcall TForm1::cxButton1Click(TObject *Sender)
{
  dxReportControl1->Parameters[L"countryParameter"]->Visible = false;
}

Hide the Dashboard Parameter

Delphi

uses
  dxDashboard.Control;   // Declares the TdxDashboardControl class

procedure TForm1.cxButton1Click(Sender: TObject);
begin
  dxDashboardControl1.Parameters['countryParameter'].Visible := False;
end;

C++

#include "dxDashboard.Control.hpp";   // Declares the TdxDashboardControl class

// Add the following linker directives to the corresponding CPP source file:
#pragma link "dxDashboard.Control"   // Required to use dxDashboard.Control.hpp declarations

void __fastcall TForm1::cxButton1Click(TObject *Sender)
{
  dxDashboardControl1->Parameters[L"countryParameter"]->Visible = false;
}
