推荐答案

的属性System.Windows.Forms.DataGridViewCell.Style 是可读/写的：

https://msdn.microsoft.com/en-us/library/system.windows.forms.datagridviewcell.style%28v=vs .110％29.aspx [ ^ ]，

https：// msdn .microsoft.com / zh-CN / library / system.windows.forms.datagridviewcellstyle（v = vs.110）.aspx [ ^ ]。



因此，您可以随时修改任何单元格的样式，或者对整行单元格进行修改。



整行，您可以使用属性 System.Windows.Forms.DataGridViewColumn.DefaultCellStyle ：

https://msdn.microsoft.com/en-us/library/system.windows.forms。 datagridviewcolumn.defaultcellstyle（v = vs.110）.aspx [ ^ ]，

https://msdn.microsoft.com/en-us/library/system.windows.forms.datagridviewcolumn%28v=vs.110%29 .aspx [ ^ ]。

The property of System.Windows.Forms.DataGridViewCell.Style is read/write:
https://msdn.microsoft.com/en-us/library/system.windows.forms.datagridviewcell.style%28v=vs.110%29.aspx[^],
https://msdn.microsoft.com/en-us/library/system.windows.forms.datagridviewcellstyle(v=vs.110).aspx[^].

So, you can always modify the style of any cell at any time, or do so for the whole row of cells.

For the whole row, you can use the property System.Windows.Forms.DataGridViewColumn.DefaultCellStyle:
https://msdn.microsoft.com/en-us/library/system.windows.forms.datagridviewcolumn.defaultcellstyle(v=vs.110).aspx[^],
https://msdn.microsoft.com/en-us/library/system.windows.forms.datagridviewcolumn%28v=vs.110%29.aspx[^].

如果您使用的是Asp.Net WebForms应用程序，请按以下步骤操作。



使用OnRowDataBound事件处理程序创建一个gridview，如下所示：

If you are using Asp.Net WebForms application, here is how you do it.

Create a gridview with OnRowDataBound event handler like below:

<asp:GridView ID="gvChangeColor" runat="server" OnRowDataBound="gvChangeColor_RowDataBound">

这里有一个示例代码根据某些条件更改行的背景颜色。您必须修改代码以满足您的需要。

And here is a sample code to change the background color of row based on some condition. You have to modify the code to suit your needs.

Protected Sub gvChangeColor_RowDataBound(sender As Object, e As GridViewRowEventArgs)
	If e.Row.RowType = DataControlRowType.DataRow Then
		If e.Row.Cells(0).Text.StartsWith("3") Then
			e.Row.BackColor = Color.Green
		End If
	End If
End Sub

如果您使用的是WinForms，请参考 Windows DataGridView中的GridView的RowDataBound等效事件 [ ^ ]



以下是如何在WinForms中执行此操作：

If you are using WinForms, then please refer this GridView's RowDataBound equivalent event in Windows DataGridView[^]

Here is how you do it in WinForms:

Private Sub dataGridView1_CellFormatting(sender As Object, e As DataGridViewCellFormattingEventArgs)
	If e.Value.ToString().StartsWith("3") Then
		dataGridView1.Rows(e.RowIndex).DefaultCellStyle.BackColor = Color.Green
	End If
End Sub
