End-User Functionality

To save the current dashboard layout state during the current session, users can click the hamburger button in the Dashboard Designer dialog and select the Save option.

If the DashboardName property value is an empty string, the Dashboard Designer dialog assigns an automatically generated name ('NewDashboard').

Related API Members

The TdxDashboardControl component displays content only when both DashboardName and Layout properties are specified. To avoid redundant redraw operations, you can set the Active property to False during batch underlying data source changes. The inactive TdxDashboardControl component displays the DashboardName property value instead of content.

The ExportTo procedure returns a string (as the AFileName parameter) that consists of the DashboardName property value with the file name extension associated with the target export format.

Code Examples

Save Dashboard Layout to File on Every Change

The following code example saves the current Dashboard layout to a file in the XML format every time a user saves pending changes in the Dashboard Designer dialog:

Delphi

uses
  dxDashboard.Control;  // Declares the TdxDashboardControl class
// ...

procedure TMyForm.dxDashboardControl1LayoutChanged(ASender: TdxCustomDashboardControl);
begin
  ASender.Layout.SaveToFile(ASender.DashboardName + '.xml');
end;

C++

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

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

void __fastcall TMyForm::dxDashboardControl1LayoutChanged(TdxCustomDashboardControl *ASender)
{
  ASender->Layout->SaveToFile(ASender->DashboardName + ".xml");
}

Save Dashboard State to File in Response to User Changes

The following code example saves the current dashboard user interaction state to a JSON file on every change:

Delphi

uses
  dxDashboard.Control;  // Declares the TdxDashboardControl class
// ...

procedure TMyForm.dxDashboardControl1StateChanged(ASender: TdxCustomDashboardControl);
begin
  ASender.State.SaveToFile(ASender.DashboardName + 'State.json');
end;

C++

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

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

void __fastcall TMyForm::dxDashboardControl1StateChanged(TdxCustomDashboardControl *ASender)
{
  ASender->State->SaveToFile(ASender->DashboardName + "State.json");
}

Default Value

The DashboardName property’s default value is an empty string.

The default DashboardName property value indicates that the ShowDesigner procedure displays an empty dashboard layout, even if the Layout property contains a non-empty layout. Any subsequent saved changes made in the Dashboard Designer dialog update both DashboardName and Layout property values.
