设置所有行的行背景色后，更改单个列的背景色 [英] Change a backcolor of a single column after a Row Backcolor for all rows is set

问题描述

我在datagrid视图中有10行，我使用VS2010.

设置所有行背景色后，如何使单列背景色?

我在表单加载事件上编写代码.我的代码在vb.net(Windows窗体)中，如下所示用于行颜色:

I have 10 rows in datagrid view and I use VS2010.

How can I make a single column backcolor after all rows backcolor is set?

I write my code on form load event. My code is in vb.net(windows form) as follows for the rows color:

Dim CountR As Integer
CountR = 0
While CountR < DataGridView1.RowCount
  If CountR Mod 2 = 0 Then
    DataGridView2.Rows(CountR).DefaultCellStyle.BackColor = Color.Pink
  Else
    DataGridView2.Rows(CountR).DefaultCellStyle.BackColor = Color.SkyBlue
  End If
  CountR = CountR + 1
End While

推荐答案

首先，我将使用:

For Each row As DataGridViewRow In DataGridView2.Rows
    If row.Index Mod 2 = 0 Then
        row.DefaultCellStyle.BackColor = Color.Pink
    Else
        row.DefaultCellStyle.BackColor = Color.SkyBlue
    End If
Next

然后，由于您已经使用Rows.DefaultCellStyle设置了背景色，因此不能简单地使用Columns.DefaultCellStyle.您将不得不再次使用Rows.DefaultCellStyle.我不知道您想如何筹办这项活动，不过例如在DGV和Column选择上使用ContextMenuStrip，您可以使用:

Then, since you''ve set the backcolor using the Rows.DefaultCellStyle you cannot simply use the Columns.DefaultCellStyle. You''ll have to use the Rows.DefaultCellStyle again. I don''t know how you want to raise the event but e.g. with a ContextMenuStrip on the DGV and Column selection, you can use:

Public Sub HighlightColumnToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles HighlightColumnToolStripMenuItem.Click
        For Each col As DataGridViewColumn In DataGridView2.SelectedColumns
            For Each row As DataGridViewRow In DataGridView2.Rows
                row.Cells(col.Index).Style.BackColor = Color.Purple
            Next
        Next
End Sub
