如何在windows form vb.net程序的datagridview中更改整列的backcolor

问题描述

您好我希望找到一种简单的方法来更改datagridview中整个列的背景颜色。我的程序是一个Windows窗体vb.net程序。这是我到目前为止，但它似乎没有工作。



datagridview1.columns（0）.defaultcellstyle.backcolor = color.blue



我非常感谢您提供的任何帮助或建议。谢谢！

Hello I'm hoping to find an easy way to change the backcolor for an entire column in a datagridview. My program is a windows forms vb.net program. This is what I have so far but it doesn't seem to be working.

datagridview1.columns(0).defaultcellstyle.backcolor = color.blue

I greatly appreciate any help or suggestions you may offer. Thanks!

推荐答案

Using con As New SqlConnection(strConnect)
    con.Open()
    Dim dt As New DataTable()
    Dim da As New SqlDataAdapter("SELECT * FROM MyTable", con)
    da.Fill(dt)
    myDataGridView.DataSource = dt
    myDataGridView.Columns(0).DefaultCellStyle.BackColor = Color.Blue
End Using

我在做什么不同于你？

What am I doing that is different from you?

Private Sub dgvfamily_CellLeave(sender As Object, e As DataGridViewCellEventArgs)
    For i As Integer = 0 To dgvfamily.Rows.Count - 1
        'dgvfamily.Rows[i].Cells[0].Value = (i + 1).ToString();
        For j As Integer = 1 To dgvfamily.Columns.Count - 1
            If dgvfamily.Rows(i).Cells(j).Value Is Nothing Then
                'dgvfamily.ClearSelection();
                dgvfamily.Rows(i).Cells(j).Style.BackColor = Color.RoyalBlue
                dgvfamily.CurrentCell = dgvfamily.Rows(i).Cells(j)
                Return
            End If
        Next
    Next

我使用这个当datagrid单元格留空时，它会改变空白单元格的颜色
