将print DataGridview的模块修改为print rtl

Question

End Sub
End Module

在按钮事件上使用它是

DataGridViewPrinter.StartPrint(DataGridView1, True, True, "PAGE DES", "NAMEPAGE")

我面临的唯一问题是从右到左开始打印

代码从左到右打印网格形式，它与打印之前的行相反

感谢提前

我修改了代码，一切都很好首先用这个替换beginprint

oStringFormat = New StringFormat
oStringFormat.FormatFlags = StringFormatFlags.DirectionRightToLeft
oStringFormat.Alignment = StringAlignment.Center
oStringFormat.LineAlignment = StringAlignment.Center
oStringFormat.Trimming = StringTrimming.EllipsisCharacter
oStringFormatComboBox = New StringFormat
oStringFormatComboBox.LineAlignment = StringAlignment.Center
oStringFormatComboBox.FormatFlags = StringFormatFlags.NoWrap
oStringFormatComboBox.Trimming = StringTrimming.EllipsisCharacter
oButton = New Button
oCheckbox = New CheckBox
oComboBox = New ComboBox
nTotalWidth = 0
For Each oColumn As DataGridViewColumn In DataGridViewToPrint.Columns
If oColumn.Visible = True Then ' Prints only Visible columns
nTotalWidth += oColumn.Width
End If
Next
nPageNo = 1
NewPage = True
nRowPos = 0

那么在打印页面上替换此

'Dim nLeft As Int16 = e.MarginBounds.Left
'If nPageNo = 1 Then
'    oColumnLefts.Clear()
'    oColumnWidths.Clear()
'    oColumnTypes.Clear()
'    For Each oColumn As DataGridViewColumn In DataGridViewToPrint.Columns
'        If oColumn.Visible = True Then
'            nWidth = CType(Math.Floor(oColumn.Width / nTotalWidth * nTotalWidth * (e.MarginBounds.Width / nTotalWidth)), Int16)
'            nHeight = e.Graphics.MeasureString(oColumn.HeaderText, oColumn.InheritedStyle.Font, nWidth).Height + 11
'            oColumnLefts.Add(nLeft)
'            oColumnWidths.Add(nWidth)
'            oColumnTypes.Add(oColumn.GetType)
'            nLeft += nWidth
'        End If
'    Next
'End If

用这个

Dim nLeft As Int16 = e.PageBounds.Right - e.PageSettings.Margins.Right
If nPageNo = 1 Then
oColumnLefts.Clear()
oColumnWidths.Clear()
oColumnTypes.Clear()
For Each oColumn As DataGridViewColumn In DataGridViewToPrint.Columns
If oColumn.Visible = True Then
nWidth = CType(Math.Floor(oColumn.Width / nTotalWidth * nTotalWidth * (e.MarginBounds.Width / nTotalWidth)), Int16)
nHeight = e.Graphics.MeasureString(oColumn.HeaderText, oColumn.InheritedStyle.Font, nWidth).Height + 11
oColumnWidths.Add(nWidth)
oColumnTypes.Add(oColumn.GetType)
nLeft = nLeft - nWidth
oColumnLefts.Add(nLeft)
End If
Next
End If

希望它能帮助像我这样有同样问题的人
