TcxCustomGridTableViewStyles.OnGetSelectionStyle Event

Allows you to change the style applied to a selected record.

Declaration

property OnGetSelectionStyle: TcxGridGetSelectionStyleEvent read; write;

Remarks

This event occurs every time the TcxGrid control is about to apply a style to a selected row. You can analyze the item type within the OnGetSelectionStyle event handler to apply different formatting to different grid item types:

Delphi

procedure TfrmGridOnGetSelectionStyle.cxGrid1DBTableView1StylesGetSelectionStyle(Sender: TcxCustomGridTableView;
  ARecord: TcxCustomGridRecord; AItem: TObject; out AStyle: TcxStyle);
var
  ASummaryItem: TcxDataSummaryItem;
begin
  if AItem is TcxGridDBColumn then
    case ARecord.RecordIndex mod 3 of
      0: AStyle := cxStyle1;
      1: AStyle := cxStyle2;
      2: AStyle := cxStyle3;
    end;

  if not ARecord.IsData then
  begin
    case Sender.DataController.DataControllerInfo.DataGroups.RowInfo[ARecord.Index].Index mod 3 of
      0: AStyle := cxStyle1;
      1: AStyle := cxStyle2;
      2: AStyle := cxStyle3;
    end;
  end;

  if AItem is TcxDataSummaryItem then
  begin
    ASummaryItem := AItem as TcxDataSummaryItem;
    if ASummaryItem.Index = 1 then
      AStyle := cxStyle1
    else
      AStyle := cxStyle2
  end;

  if AItem is TcxDataGroupSummaryItems then
    AStyle := cxStyle3;
end;

C++

void __fastcall TfrmGridOnGetSelectionStyle::cxGrid1DBTableView1StylesGetSelectionStyle(
  TcxCustomGridTableView *Sender, TcxCustomGridRecord *ARecord,
  TObject *AItem,  TcxStyle *&AStyle)
{
  TcxDataSummaryItem *ASummaryItem;
  if(AItem->ClassType() == __classid(TcxGridDBColumn))
  {
    switch (ARecord->RecordIndex/3)
    {
      case 0: AStyle = cxStyle1; break;
      case 1: AStyle = cxStyle2; break;
      case 2: AStyle = cxStyle3; break;
    }
  }

  if(!ARecord->IsData)
  {
    switch (Sender->DataController->DataControllerInfo->DataGroups->RowInfo[ARecord->Index]->Index/3)
    {
      case 0: AStyle = cxStyle1; break;
      case 1: AStyle = cxStyle2; break;
      case 2: AStyle = cxStyle3; break;
    }
  }

  if(AItem->ClassType() == __classid(TcxDataSummaryItem))
  {
    ASummaryItem = dynamic_cast<TcxDataSummaryItem*>(AItem);
    if(ASummaryItem->Index == 1)
      AStyle = cxStyle1;
    else
      AStyle = cxStyle2;
  }

  if(AItem->ClassType() == __classid(TcxDataGroupSummaryItems))
    AStyle = cxStyle3;
}
