根据列字段值更改gridview行forecolor

Question

我的gridview列中有一个值，它将确定整行的值是否应为红色。我做了以下但不知何故，每一行都是红色的。请善意的建议。感谢。

Protected Sub uigvList_RowCreated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles uigvList.RowCreated

    If e.Row.RowType = DataControlRowType.DataRow Then
        If Not (DataBinder.Eval(e.Row.DataItem, "VoidOn")) Is Nothing Then ' This is the condition, if this field is not blank then I want to the entire row to have red colored values.
            e.Row.BackColor = Drawing.Color.Firebrick
        End If
    End If

End Sub

Answer 1

也许 DBNull.Value ？

If (DataBinder.Eval(e.Row.DataItem, "VoidOn")) IsNot DBNull.Value Then ...

If e.Row.DataItem("VoidOn") IsNot DBNull.Value Then ...

PS：您可以在调试模式下检查 VoidOn 值，只需将断点设置为代码行。
