主题：[求助]请问实现选定复选框打印关联印的代码

http://www.foxtable.com/help/topics/1250.htm

这个实例中，是选定行打印连续关联表

我想请问，如何通过复选框来选择要打印的行呢？

首先显示复选框：

打印选中的行：

Dim doc As New PrintDoc '定义一个新报表
Dim rt As New prt.RenderTable '定义一个新表格
Dim tb As Table = Tables("订单")
rt.Width = "Auto" '表格宽度为自动,也就是等于各列设置宽度之和
rt.SplitHorzBehavior = prt.SplitBehaviorEnum.SplitIfNeeded '表格宽度超出页宽时,可以水平换页
rt.Style.Font = tb.Font
Dim rs As List(of Row) = Tables("订单").GetCheckedRows
For c As Integer = 0 To tb.Cols.Count -1 '逐列设置和填入内容
    rt.Cells(0,c).Text = tb.Cols(c).Name '列名作为标题
    rt.Cells(0,c).Style.TextAlignHorz = prt.AlignHorzEnum.Center '标题内容水平居中
    rt.Cols(c).Width = tb.Cols(c).PrintWidth '列宽等于实际列宽
    If tb.Cols(c).IsNumeric OrElse tb.Cols(c).IsDate Then '如果是数值或日期列
        rt.Cols(c).Style.TextAlignHorz = prt.AlignHorzEnum.Right '数据水平靠右
    End If
    For r As Integer = 0 To rs.Count -1 '开始填入该列内容
        rt.Cells(r + 1, c).Text = rs(r)(c)
    Next
Next
rt.Style.Gridlines.All = New prt.Linedef(Color.Gray) '灰色网格线
rt.CellStyle.Spacing.All = 0.5 '单元格内距设为0.5毫米
rt.Rows(0).Style.TextAlignHorz = prt.AlignHorzEnum.Center '第一行内容水平居中
rt.RowGroups(0,1).Header = prt.TableHeaderEnum.All '利用行组,将第一行设为表头
doc.Body.Children.Add(rt) '将表格加入到报表
doc.Preview()

谢谢狐爸，已搞定

现在又有另一个问题

这个实例，会按父表的行自动换页

那么怎么实现，连续打印的时候，有时候关联表太多项，再进行自动换页呢，换页的时候要保持表头不变。

求教~

例如关联表每页5行：

Dim doc As New Printdoc
Dim rx As prt.RenderText
Dim rt As prt.RenderTable
rx = New prt.RenderText
rx.Style.FontSize = 14
rx.Style.FontBold = True
rx.Style.Spacing.Bottom = 5
rx.Text = "类别: " & Tables("类别").Current("类别名称")
doc.Body.Children.Add(rx)
With Tables("类别.产品")
    For r As Integer = 0 To .Rows.Count - 1 Step 5 '关联表每页5行
        rt = New prt.RenderTable
        rt.Style.TextAlignHorz = prt.AlignHorzEnum.Center
        rt.Style.TextAlignVert = prt.AlignVertEnum.Center
        rt.Style.Borders.Bottom = New prt.LineDef(0.3,Color.LightGray)
        rt.CellStyle.Spacing.All = 1
        rt.Cols.Count = 4
        rt.Cells(0,0).Text = "产品名称"
        rt.Cells(0,1).Text = "单价"
        rt.Cells(0,2).Text = "库存量"
        rt.Cells(0,3).Text = "订购量"
        rt.Cells(0,4).Text = "再订购量"
        rt.Cells(0,5).Text = "中止"
        rt.rows(0).Style.Borders.Top = New prt.LineDef(1,Color.LightGray)
        rt.rows(0).Style.Borders.Bottom = New prt.LineDef(1,Color.LightGray)
        For n As Integer = r To math.min( r + 5,.Rows.count -1)
            rt.Cells(n - r + 1,0).Text = .rows(n)("产品名称")
            rt.Cells(n - r + 1,1).Text = .rows(n)("单价")
            rt.Cells(n - r + 1,2).Text = .rows(n)("库存量")
            rt.Cells(n - r + 1,3).Text = .rows(n)("订购量")
            rt.Cells(n - r + 1,4).Text = .rows(n)("再订购量")
            If .rows(r)("中止") = True Then
                Dim rm As New prt.RenderImage
                rm.Image = getImage("Check.Ico")
                rm.Style.ImageAlign.AlignHorz = prt.ImageAlignHorzEnum.Center
                rm.Style.ImageAlign.StretchHorz = False
                rm.Style.ImageAlign.StretchVert = False
                rt.Cells(n - r + 1,5).RenderObject = rm
            End If
        End If
    Next
End With
doc.Body.Children.Add(rt)

rx = New prt.RenderText
rx.Style.FontBold = True
rx.Style.Spacing.Top = 3
rx.Text = "产品数目: " & Tables("类别.产品").Rows.Count
rx.Style.TextAlignHorz = prt.AlignHorzEnum.Right
doc.Body.Children.Add(rx)

我之前提供的只是思路，需要自行调整的。

下面的代码测试通过：

Dim doc As New Printdoc
Dim rx As prt.RenderText
Dim rt As prt.RenderTable

With Tables("类别.产品")
    For r As Integer = 0 To .Rows.Count - 1 Step 5 '关联表每页5行
        rx = New prt.RenderText
        rx.Style.FontSize = 14
        rx.Style.FontBold = True
        rx.Style.Spacing.Bottom = 5
        rx.Text = "类别: " & Tables("类别").Current("类别名称")
        doc.Body.Children.Add(rx)
        rt = New prt.RenderTable
        rt.Style.TextAlignHorz = prt.AlignHorzEnum.Center
        rt.Style.TextAlignVert = prt.AlignVertEnum.Center
        rt.Style.Borders.Bottom = New prt.LineDef(0.3,Color.LightGray)
        rt.CellStyle.Spacing.All = 1
        rt.Cols.Count = 4
        rt.Cells(0,0).Text = "产品名称"
        rt.Cells(0,1).Text = "单价"
        rt.Cells(0,2).Text = "库存量"
        rt.Cells(0,3).Text = "订购量"
        rt.Cells(0,4).Text = "再订购量"
        rt.Cells(0,5).Text = "中止"
        rt.rows(0).Style.Borders.Top = New prt.LineDef(1,Color.LightGray)
        rt.rows(0).Style.Borders.Bottom = New prt.LineDef(1,Color.LightGray)
        For n As Integer = r To math.min( r + 4,.Rows.count -1)
            rt.Cells(n - r + 1,0).Text = .rows(n)("产品名称")
            rt.Cells(n - r + 1,1).Text = .rows(n)("单价")
            rt.Cells(n - r + 1,2).Text = .rows(n)("库存量")
            rt.Cells(n - r + 1,3).Text = .rows(n)("订购量")
            rt.Cells(n - r + 1,4).Text = .rows(n)("再订购量")
            If .rows(r)("中止") = True Then
                Dim rm As New prt.RenderImage
                rm.Image = getImage("Check.Ico")
                rm.Style.ImageAlign.AlignHorz = prt.ImageAlignHorzEnum.Center
                rm.Style.ImageAlign.StretchHorz = False
                rm.Style.ImageAlign.StretchVert = False
                rt.Cells(n - r + 1,5).RenderObject = rm
            End If
        Next
        doc.Body.Children.Add(rt)
        If r + 4 < .Rows.Count - 1 Then
            Dim rp As prt.RenderEmpty '定一个空对象
            rp = new prt.RenderEmpty '定义一个新的空对象
            rp.BreakBefore = prt.BreakEnum.Page '打印前换页
            doc.Body.Children.Add(rp) '加入到报表中
        End If
    Next
End With
rx = New prt.RenderText
rx.Style.FontBold = True
rx.Style.Spacing.Top = 3
rx.Text = "产品数目: " & Tables("类别.产品").Rows.Count
rx.Style.TextAlignHorz = prt.AlignHorzEnum.Right
doc.Body.Children.Add(rx)

doc.Preview()
