这是从索引中调用的局部视图。在模型中，JobStatusSortOrder 设置为可为空的双精度。在这里，如果用户在内联编辑期间没有输入任何值，我如何将值默认设置为 null。我曾尝试寻找默认文本等选项，但找不到任何可以帮助我的选项。有人可以帮我吗？谢谢！

@model MyProject.Web.ViewModels.ProjectStatusListViewModel

试试这个：

@{
Html.EnableClientValidation(true);

var grid = Html.DevExpress().GridView(
    settings =>
    {
        //your code
        //Add this code to initialize the rows for a New Row
        settings.InitNewRow = (sender, e) =>
        {
                e.NewValues["JobStatusSortOrder"] = 0; // set the default value as 0
        };
    });
}@grid.Bind(Model.JobStatus.ToList()).GetHtml()

由于它是数字类型，因此 DevExpress 网格中的任何空值都应等于数据结构中的 null。你不能只检查空字符串的编辑值，然后在发送到数据层之前将它们设置为 null 吗？
