网格部分视图中未保留ViewData

Question

我有一个自定义的网格视图，它使用的renderRow助手类似于乌尔维什帖子在这里https://our.umbraco.org/forum/umbraco-7/using-umbraco-7/64536-How-to-use-grids-with-views-and-maybe-controls-to-make-it-look-good

我尝试使用TempData将网格设置传递给网格局部面板，但是TempData对于我的PartialViewMacroPageExtensions类和宏局部视图本身都是null。

        @foreach (var control in area.controls) {
            if (control != null && control.editor != null && control.editor.view != null) {
                TempData["grid-settings"] = area.config;
               <text>@Html.Partial("grid/editors/base", (object)control)</text>
            }
        }


public static class PartialViewMacroPageExtensions
{
    public static T GetGridProperties<T>(this PartialViewMacroPage page)
        where T : new()
    {
        if (page.TempData["grid-settings"] != null)
        {
            return JsonConvert.DeserializeObject<T>(page.TempData["grid-settings"].ToString());
        }

        return new T();
    }
}

有没有办法将网格元素设置传递给它的局部视图？

Please use this code for keep tempdata value  where you stored TempData.

TempData.Keep(“TempDataName”);
