Life is but a dream

엑셀 내보내기시 이런 식으로 (모든 컬럼이 최소사이즈로) 출력된다면..

당황하지 말고

BestFitColumns 메소드를 이용하면 해결됨..

단.. BestFitColumns 전에 AutoWith 값을 false로 해줘야함.

advBandedGridView.OptionsPrint.AutoWidth = false;
advBandedGridView.OptionsView.ColumnAutoWidth = false;
advBandedGridView.BestFitColumns();

이건 삽질 1시간 짜리임.

Tip.하나 더~

Band Header width 에 Column Width를 맞추고 싶다면

private void BestFitBands(AdvBandedGridView view)
{
            view.BeginUpdate();
            view.OptionsView.ShowColumnHeaders = true;
            foreach (BandedGridColumn col in view.Columns)
                col.Caption = col.OwnerBand.Caption;
            view.BestFitColumns();
            view.OptionsView.ShowColumnHeaders = false;
            view.EndUpdate();
}

엑셀 출력시.. 가장쉬운 방법이

Grid에 Data Binding 한 후 그대로 Export 하는 방법인데..

//

gridControl.ExportToXlsx(path);

했더니 .. 그리드 헤더 부분이 아래처럼 Grouping 되서 출력된다...

문제는 ExportType!

// Export 시, 아래처럼 옵션을 설정할 수 있다

XlsxExportOptionsEx xlsxOptions = new XlsxExportOptionsEx();
xlsxOptions.ShowGridLines = true;   // 라인출력 
xlsxOptions.SheetName = "test";    // sheet 명
xlsxOptions.ExportType = DevExpress.Export.ExportType.WYSIWYG;    // ExportType

gridControl.ExportToXlsx(exportFilePath, xlsxOptions);

WYSIWYG (위지윅)이란? what you see is what you get  (보이는 데로 얻는다. )

보이는 그데로 출력된다는 IT 용어.

이제야 내가 의도한데로 나옴.. 삽질 3시간함.
