如何设置复选框内部的颜色-asp.net

你不能用css做到这一点。众所周知,表单很难设计样式( technical explanation from Eric Meyer

但是,您可以使用javascript将复选框完全替换为图像,但仍然保留普通checkbox元素的格式编码。 Here's an example using jquery

Public Sub SetColor()
    Try
        For i As Integer = 0 To gvMaster.Rows.Count - 1
            FN = gvMaster.Rows(i).Cells(3).Text
            If FN = "Present" Then
                gvMaster.Rows(i).Cells(3).ForeColor = Color.Green
            End If
            If FN = "Absent" Then
                gvMaster.Rows(i).Cells(3).ForeColor = Color.Red
            End If

            AN = gvMaster.Rows(i).Cells(4).Text
            If AN = "Present" Then
                gvMaster.Rows(i).Cells(4).ForeColor = Color.Green
            End If
            If AN = "Absent" Then
                gvMaster.Rows(i).Cells(4).ForeColor = Color.Red
            End If
        Next
    Catch generatedExceptionName As Exception
    End Try
End Sub
