当selectionMode=fullRowSelect时,如何突出显示DataGridView中的当前单元格

我使用CellFormatting事件找到了一种更好的方法:

Private Sub uxContacts_CellFormatting(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles uxContacts.CellFormatting
    If uxContacts.CurrentCell IsNot Nothing Then
        If e.RowIndex = uxContacts.CurrentCell.RowIndex And e.ColumnIndex = uxContacts.CurrentCell.ColumnIndex Then
            e.CellStyle.SelectionBackColor = Color.SteelBlue
        Else
            e.CellStyle.SelectionBackColor = uxContacts.DefaultCellStyle.SelectionBackColor
        End If
    End If
End Sub

为了我 CellFormatting 就这样。我有一组可以编辑的列(我让它们以不同的颜色显示),这是我使用的代码:

Private Sub Util_CellFormatting(ByVal Sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles dgvUtil.CellFormatting
    If dgvUtil.CurrentCell IsNot Nothing Then
        If e.RowIndex = dgvUtil.CurrentCell.RowIndex And e.ColumnIndex = dgvUtil.CurrentCell.ColumnIndex And (dgvUtil.CurrentCell.ColumnIndex = 10 Or dgvUtil.CurrentCell.ColumnIndex = 11 Or dgvUtil.CurrentCell.ColumnIndex = 13) Then
            e.CellStyle.SelectionBackColor = Color.SteelBlue
        Else
            e.CellStyle.SelectionBackColor = dgvUtil.DefaultCellStyle.SelectionBackColor
        End If
    End If
End Sub

要使用DataGridView RowPostpaint方法。让框架绘制行,然后返回到您感兴趣的单元格中进行着色。

示例如下: MSDN

试试这个,onmousemove方法:

Private Sub DataGridView1_CellMouseMove(sender As Object, e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles DataGridView1.CellMouseMove
    If e.RowIndex >= 0 Then
        DataGridView1.Rows(e.RowIndex).Cells(e.ColumnIndex).Style.SelectionBackColor = Color.Red
    End If
End Sub

Private Sub DataGridView1_CellMouseLeave(sender As Object, e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellMouseLeave
    If e.RowIndex >= 0 Then
        DataGridView1.Rows(e.RowIndex).Cells(e.ColumnIndex).Style.SelectionBackColor = DataGridView1.DefaultCellStyle.SelectionBackColor
    End If
End Sub
