Spread基本知识（一）

1.FpSpread控件获取当前行号和列号

        With Me.FpSpread1.ActiveSheet
            Dim str As String = String.Format("当前行号 {0} 当前列号 {1}", .ActiveRow.Index, _
                                                                            .ActiveColumn.Index)
            Me.ShowMesage(str)
            str = String.Format("当前行号 {0} 当前列号 {1}", .ActiveRow.Index2, _
            .ActiveColumn.Index2)
            Me.ShowMesage(str)
        End With

2.FpSpread控件选择单元格时,更改这一行的颜色

      '判断是否点击列头
        If Not e.ColumnHeader Then
            Dim sheet As FarPoint.Win.Spread.SheetView = e.View.Sheets(e.View.ActiveSheetIndex)

            Me.ShowMesage(String.Format("共有 {0} 行", sheet.Rows.Count))

            sheet.Rows(e.Row).BackColor = Color.Blue
            For i As Integer = 0 To sheet.Rows.Count - 1
                If i <> e.Row Then
                    sheet.Rows(i).BackColor = sheet.DefaultStyle.BackColor
                End If
            Next
        End If

3.FpSpread控件单元格的设置值,获取值

        '获取当前单元格
        If Not Me.FpSpread1.ActiveSheet.ActiveCell Is Nothing Then
            Me.ShowMesage("当前单元格的值 " & Me.FpSpread1.ActiveSheet.ActiveCell.Text)
        End If

        '获取指定位置单元格的值
        Dim cell As FarPoint.Win.Spread.Cell = Me.FpSpread1.ActiveSheet.Cells(1, 1)
        Me.ShowMesage("(1,1) 单元格的值 " & cell.Text)

        'tag的应用
        cell = Me.FpSpread1.ActiveSheet.Cells(1, 2)
        cell.Tag = "ppome"

        cell = Me.FpSpread1.ActiveSheet.Cells("ppome")
        If cell Is Nothing Then
            Me.ShowMesage("按tag 获取单元失败,ppome 不存在")
        Else
            Me.ShowMesage(String.Format("{0},{1} 单元格值 {2}", cell.Row.Index, cell.Column.Index, cell.Text))
        End If
按tag获取时,如果存在有相同的tag则只返回一个?就近一个吧.

  '设置单元格的值
        If Not Me.FpSpread1.ActiveSheet.ActiveCell Is Nothing Then
            Me.FpSpread1.ActiveSheet.ActiveCell.Text = "http://www.ppome.cn"
        Else
            MessageBox.Show("没有选择单元格.")
        End If

4.FpSpread控件通过下键选择单元格时时,更改行的颜色

        Dim sheet As FarPoint.Win.Spread.SheetView = Me.FpSpread1.ActiveSheet
        sheet.Rows(e.NewRow).BackColor = Color.Cyan
        For i As Integer = 0 To sheet.Rows.Count - 1
            If i <> e.NewRow Then
                sheet.Rows(i).BackColor = sheet.DefaultStyle.BackColor
            End If
        Next
