如何复制datagrid中的最后一行

Question

使用VB.Net

我想将最后一行值复制到新行

代码

   Dim rcount As Int32
    For i As Integer = 0 To gridview1.RowCount - 1
    gridview1.Rows.Add()
    rcount = gridview1.RowCount() - 1
    For j As Integer = 0 To gridview1.Rows(i).Cells.Count - 1
    gridview1.Rows(rcount).Cells(j).Value = gridview1.Rows(i).Cells(j).Value
    Next
    gridview1.Rows(rcount).Cells(1).Value = rcount + 1
    rcount = 0
    Next

上面的代码正在运行，但是它将所有前一行复制到新行，我想将最后一行复制到新行

如何解决这个问题。

需要VB.Net代码帮助

Answer 1

如果您只想将最后一行复制到新行，请执行此操作。

    Dim LastRow As Integer = DataGridView1.Rows.Count - 1
    Dim Newrow As Integer = DataGridView1.Rows.Add()
    For i As Integer = 0 To DataGridView1.Columns.Count - 1
        DataGridView1.Rows(Newrow).Cells(i).Value = DataGridView1.Rows(LastRow).Cells(i).Value
    Next

如果您始终存在空白的可编辑行，则此操作无效。然后你需要从“Dim LastRow”行中减去2。
