Acumatica 在 PXView 中设置特定列/单元格的样式？

Question

我对 Acumatica 编码非常陌生。我正在尝试更改 AR303000 标题页上单元格的颜色。 （参见下面的代码）。显然这是行不通的。我收到错误消息 PXFormViewEventArgs 在命名空间 PX.Web.UI 中不存在。
谁能指导我应该使用哪个命名空间并更正我的代码以使其工作？ 谢谢你，

我认为你可以检测Form和UsrReadonlyAcctName的控件，然后在Page_Load期间应用Css样式；下面是一个示例，但就我而言，我找到一个网格，然后在 RowDataBound 期间检测单元格的值：

     public override void Initialize()
    {
        //Access page via http context current handler
        Page page = HttpContext.Current?.Handler as PXPage;
        if (page != null)
        {
            page.Load += Page_Load;
        }
    }

    private void Page_Load(object sender, EventArgs e)
    {
        Page page = (Page)sender;

        RegisterStyle(page, "MyCssRed", "#FD9999 !important", null, false);

        PX.Web.UI.PXGrid grdMyGridControl = (PX.Web.UI.PXGrid)ControlHelper.FindControl("grid2", page);  // Allocations popup

        if (grdMyGridControl != null)
        {
            grdMyGridControl.RowDataBound += (object grdsender, PXGridRowEventArgs erdb) =>
            {
                var data = erdb.Row;
                if (data == null) { return; }
                bool isRed = false;

                PXGridCell cell = data.Cells["INItemLotSerialKvExt__ValueString"];
                if (cell == null) return;
                Object value = cell.Value;
                if (value != null && (String)value == "R")
                {
                    isRed = true;
                }
                
                ...
                                
                if (isRed)
                        data.Style.CssClass = "MyCssRed";

下面是销售订单页面 SO301000 上的示例，该示例查找“客户订单编号”文本框并在其文本为空时添加颜色：

    private void Page_Load(object sender, EventArgs e)
    {
        Page page = (Page)sender;

        RegisterStyle(page, "MyCssRed", "#FD9999 !important", null, false);

        PX.Web.UI.PXTextEdit myBox = (PX.Web.UI.PXTextEdit)ControlHelper.FindControl("edCustomerOrderNbr", page);

        if (myBox != null)
        {
            myBox.DataBinding += (object boxsender, EventArgs boxargs) =>
            {
                PX.Web.UI.PXTextEdit box = boxsender as PX.Web.UI.PXTextEdit;
                string cellText = box.Text;
                box.CssClass = string.IsNullOrEmpty(cellText) ? "MyCssRed" : "editor";
            };
        }
