Question

在控制器中我设置了值：

ViewBag.incremento = 5;

我有以下观点：

@model IEnumerable<Gestor.Models.PlanejVenda>

@{
ViewBag.Title = "Índice";
Layout = "~/Views/Shared/_Layout.cshtml";
}

<h2>Índice</h2>

<p>
@Html.ActionLink("Criar novo planejamento de compra", "Create")
</p>

<div class="row">
    <div class="col-md-6">
        @using (Html.BeginForm("Search", "PlanejVendas", FormMethod.Post))
        {
            <p>
                Código: @Html.TextBox("search")
                <input type="submit" value="Procurar" />
            </p>
        }
    </div>
    <div class="col-md-6">
        @using (Html.BeginForm("Search", "PlanejVendas", FormMethod.Post))
        {
            <p>
                Incremento Global: @Html.TextBox("search", new {@ViewBag.incremento })
                <input type="submit" value="Confirmar" />
            </p>
        }
    </div>
</div>

<table class="table table-hover">
    <tr>

    Regula table here showing Ok

我原以为我会有文本框内控制器设置的清理值5。但它显示：“{incremento = 5}”而不是

如何才能获得ViewBag的值，在示例中只是数字5？

你可以试试。

        <h2>Choose Grid Size</h2>
        <form id="sizePicker">
            Grid Height:
            <input type="number" id="inputHeight" name="height" min="1" value="11">
            Grid Width:
            <input type="number" id="inputWeight" name="width" min="1" value="11">
            <input type="submit">
        </form>

        <h2>Pick A Color</h2>
        <input type="color" id="colorPicker">
    </div>

    <h2>Design Canvas</h2>
    <table id="pixelCanvas">
        <tbody id="tableBody">

        </tbody>
    </table>

    <script src="designs.js"></script>
</body>
</html>

而不是

@Html.TextBox("search", (string)@ViewBag.incremento)

Answer 2

将ViewBag与TextBox分开。 ViewBag返回需要转换为正确类型的对象集合。

测试忽略ViewBag并使用常量。

new正在做的是创建匿名类型而不是值。尝试

@Html.TextBox("search", "5")

如果有效，那么将ViewBag项目转换为字符串，因为D-Shih的答案表明......

Answer 3

试试这个：

Incremento Global: @Html.TextBox("search", new { @value= ViewBag.incremento })

获取ViewBag的干净值
