• Jul 29, 2021

The following code snippet demonstrates how to filter a dataset by handling the OnChange event of a TdxBarEdit. The TdxBarEdit.Text property provides a filter value.

Delphi

procedure TForm1.dxBarEdit1Change(Sender: TObject);
begin
  Datasource1.Dataset.Filter := 'FieldName1 = '''+ dxBarEdit1.Text + '''';
  Datasource1.Dataset.Filtered := True;
end;

C++

void __fastcall TForm1::dxBarEdit1Change(TObject * Sender)
{
  DataSource1->DataSet->Filter = "FieldName1 = "+ dxBarEdit1->Text + "'";
  DataSource1->DataSet->Filtered = true;
}
