DataGridView row的颜色[在线等]
判定某一个Cell的值
然后把符合条件的Cell所在的Row里所有的Cell的背景色都改成指定的颜色
也就是改变row的背景色

How do I color a individual cell depending upon its value or some external method?

[VB.NET}

Public Class DataGridColoredTextBoxColumn

Inherits DataGridTextBoxColumn



Public Sub New()

End Sub



Protected Overloads Overrides Sub Paint(ByVal g As Graphics, ByVal bounds As Rectangle, ByVal source As CurrencyManager, ByVal rowNum As Integer, ByVal backBrush As Brush, ByVal foreBrush As Brush, ByVal alignToRight As Boolean)



' the idea is to conditionally set the foreBrush and/or backbrush

' depending upon some crireria on the cell value

' Here, we color anything that begins with a letter higher than 'F '

Try

Dim o As Object

o = Me.GetColumnValueAtRow(source, rowNum)

If (Not (o) Is Nothing) Then

Dim c As Char

c = CType(o, String).Substring(0, 1)

If (c > "F ") Then

' could be as simple as

' backBrush = new SolidBrush(Color.Pink);

' or something fancier...

backBrush = New LinearGradientBrush(bounds, Color.FromArgb(255, 200, 200), Color.FromArgb(128, 20, 20), LinearGradientMode.BackwardDiagonal)

foreBrush = New SolidBrush(Color.White)

End If

End If

Catch ex As Exception

' empty catch

Finally

' make sure the base class gets called to do the drawing with

' the possibly changed brushes

MyBase.Paint(g, bounds, source, rowNum, backBrush, foreBrush, alignToRight)

End Try



End Sub

End Class


[解决办法]
如果是Winform则使用CellFormatting事件处理

自己改一下
我是用C#写的，现在忙，你自己改一下
