XtraReport交叉表自適應行高及最佳列寬

1.自適應行頭的行高，綁定CustomRowHeight事件，代碼如下：

private Graphics gr = Graphics.FromHwnd(IntPtr.Zero);

private void pivotGrid1_CustomRowHeight(object sender, HuanSi.XtraReports.UI.PivotGrid.PivotCustomRowHeightEventArgs e) {

e.RowHeight = 20;

var grid=sender as HuanSi.XtraReports.UI.XRPivotGrid;

var list=e.Data.GetFieldsByArea(HuanSi.XtraPivotGrid.PivotArea.RowArea, false);

foreach (var item in list)

{

??????? var obj=grid.GetFieldValue(item, e.RowIndex);

??????? if (obj == null)

??????? continue;

??????? var font = (item as HuanSi.XtraReports.UI.PivotGrid.XRPivotGridField).Appearance.Cell.Font;

??????? SizeF size = gr.MeasureString(obj.ToString(), font, item.Width);

??????? int height = Convert.ToInt32(Math.Ceiling(size.Height));

??????? e.RowHeight = e.RowHeight > height ? e.RowHeight : height;

}

}

效果圖如下：

2.自適應數據的行高，同樣綁定CustomRowHeight事件，代碼如下：

private Graphics gr = Graphics.FromHwnd(IntPtr.Zero);

private void xrPivotGrid1_CustomRowHeight_1(object sender, PivotCustomRowHeightEventArgs e) {

e.RowHeight = 0;

for (int i = 0; i <= e.ColumnCount - 1; i++) {

string value = e.GetRowCellValue(i).ToString();

SizeF size = gr.MeasureString(value, e.DataField.Appearance.Cell.Font, e.DataField.Width);

int height = Convert.ToInt32(Math.Ceiling(size.Height));

e.RowHeight = e.RowHeight > height ? e.RowHeight : height;

}

}

3.自適應列寬

自適應列寬則極其簡單，綁定BeforePrint事件即可，代碼如下：

private void pivotGrid1_BeforePrint(object sender, System.Drawing.Printing.PrintEventArgs e) {

var grid=sender as HuanSi.XtraReports.UI.XRPivotGrid;

grid.BestFit();

}

再次盜用DX官方的一張效果圖：
