TdxTileControlItemDetailOptions.DetailControl Property

Associates a control to be displayed by a detail page on tile activation.

Declaration

property DetailControl: TWinControl read; write;

Property Value

Type
TWinControl

Remarks

Use this property to associate a tile item with a detail control (any TWinControl descendant, for instance, TFrame). Activating the tile item using either a click or tap will display the associated detail control in a detail page.

With the DetailControl property, you can vary tile activation results for individual tile items, making them context-sensitive or conditional. For example, you can handle a tile item’s OnActiveFrameChanged event to switch the DetailControl property value based on the currently active tile frame, as shown below.

Delphi

procedure <Form>.<TileControlItem>.ActiveFrameChanged(Sender: TdxTileControlItem)
var
  ADetailControl: TWinControl;
begin
  case Sender.ActiveFrameIndex of
    1: ADetailControl := Panel2;
    2: ADetailControl := Panel3;
  else
    ADetailControl := Panel1;
  end;
  Sender.DetailOptions.DetailControl.Visible := False;
  Sender.DetailOptions.DetailControl := ADetailControl;
end;

C++

void __fastcall TForm1::dxTileControl1Item1ActivateFrameChanged(TdxTileControlItem *Sender)
{
  TWinControl *ADetailControl;
  switch(Sender->ActiveFrameIndex)
  {
    case 1: ADetailControl = Panel2; break;
    case 2: ADetailControl = Panel3; break;
    default: ADetailControl = Panel1; break;
  }
  Sender->DetailOptions->DetailControl->Visible = false;
  Sender->DetailOptions->DetailControl = ADetailControl;
}

This code example rotates TPanel objects (Panel1, Panel2, and Panel3) as a tile item’s detail control.

You can programmatically show or close detail pages via a tile item’s ActivateDetail and DeactivateDetail methods. To respond to item activations, handle a tile item’s OnActivateDetail and OnDeactivateDetail events.
