Question

您好我正在寻找2天我没有找到任何工作我有booklist datagridview，它在数据库中绑定，并且有一个未绑定的复选框列和另一个用于在表单中存储检查行的dgv。

因此，当我在booklist中检查了一行时，它将存储在另一个dgv中，所以当我对其进行排序时，检查状态将不会被删除

 Private Sub BooksDataGridView_CellFormatting(sender As Object, e As DataGridViewCellFormattingEventArgs) Handles BooksDataGridView.CellFormatting
    For Each row As DataGridViewRow In BooksDataGridView.Rows
        If row.Cells("Edit").Value = False Then
            row.Cells(0).Style.BackColor = Color.FromArgb(0, 41, 75)
        Else
            row.Cells(0).Style.BackColor = Color.SeaGreen
            row.Cells(0).Style.SelectionBackColor = Color.MediumSeaGreen
        End If

    Next
    For i As Integer = 0 To DataGridView1.RowCount - 1
        Dim tid = DataGridView1.Rows(i).Cells(0).Value
        Dim sid = DataGridView1.Rows(i).Cells(1).Value
        Dim type = DataGridView1.Rows(i).Cells(2).Value
        For j As Integer = 0 To BooksDataGridView.RowCount - 1
            If BooksDataGridView.Rows(j).Cells(1).Value = tid And BooksDataGridView.Rows(j).Cells(2).Value = sid And type = "Book" Then
                BooksDataGridView.Rows(j).Cells("Edit").Value = True
                BooksDataGridView.Rows(j).Cells("stat").Value = 1
            End If
        Next
    Next
    'BooksDataGridView.Sort(BooksDataGridView.Columns(20), System.ComponentModel.ListSortDirection.Descending)
End Sub

单元格格式化通过在另一个dgv

中循环来保持检查状态

现在我的问题是我要将已检查的行整理到图书清单的顶部
