XtraGrid(DevExpress) 比较 VB.net 中的 Date Installed 列和 Date Expired 列

Question

我只想问是否可以比较 xtragrid gridView1.Columns("DateInstalled") 和 Date.today？

这是我的代码，它对我不起作用：

Private Sub GridView1_RowCellStyle(sender As Object, e As Views.Grid.RowCellStyleEventArgs) Handles GridView1.RowCellStyle
        Dim dateExp As Date = Date.Parse(GridView1.Columns("DateExpired"))

        If dateExp < Date.Today Then
            e.Appearance.BackColor = Color.Red
        End If
    End Sub

输出是，如果 Date.Today 大于 column("DateExpired")，它会用高亮填充整行，表示它已过期。

真诚的，

试试这个：

   Private Sub GridView1_RowCellStyle(sender As Object, e As DevExpress.XtraGrid.Views.Grid.RowCellStyleEventArgs) Handles GridView1.RowCellStyle

        Dim dateExp As Date = Date.Parse(GridView1.GetRowCellValue(e.RowHandle, "DateExpired"))

        If dateExp < Date.Today Then
            e.Appearance.BackColor = Color.Red
        End If

    End Sub
