如何预览XtraGrid控件

以下示例显示如何预览XtraGrid。

C#

private void ShowGridPreview(DevExpress.XtraGrid.GridControl grid) {
// Check whether the Grid Control can be previewed.
if(!grid.IsPrintingAvailable) {
MessageBox.Show("The 'DevExpress.XtraPrinting' Library is not found", "Error");
return;
}
// Opens the Preview window.
grid.ShowPreview();
}

VB.NET

Sub ShowGridPreview(ByVal grid As DevExpress.XtraGrid.GridControl)
' Check whether the Grid Control can be previewed.
If Not grid.IsPrintingAvailable Then
MessageBox.Show("The 'DevExpress.XtraPrinting' Library is not found", "Error")
Return
End If
' Opens the Preview window.
grid.ShowPreview()
End Sub

下图显示了示例网格的预览窗口。

如何自定义打印外观

以下示例代码演示了如何将打印外观和背景颜色自定义应用于网格控件中的偶数行。

C#

gridView1.OptionsPrint.UsePrintStyles = true;
// Enable the AppearancePrint.EvenRow property's settings.
gridView1.OptionsPrint.EnableAppearanceEvenRow = true;
// Set the background color of the even rows.
gridView1.AppearancePrint.EvenRow.BackColor = Color.LightYellow;

VB.NET

GridView1.OptionsPrint.UsePrintStyles = True
' Enable the AppearancePrint.EvenRow property's settings.
GridView1.OptionsPrint.EnableAppearanceEvenRow = True
' Set the background color of the even rows.
GridView1.AppearancePrint.EvenRow.BackColor = Color.LightYellow

结果如下图所示。
