如何在 ASP.NET 的 select 框中将我的模型字段设置为选定值？

Question

I have the following editor-field with a select list inside:

<div class="editor-field">
    <select name="listbox" id="listbox">
        @foreach (var item in Model.ExerciseName)
        {
            <option value="@item.Name">
                @item.Name
            </option>
        }
    </select>
</div>

My model has a field ChosenExercise. Is There an easy way to set Model.ChosenExercise to the selected value?

Answer 1

Add option with selected="selected" before your foreach

<div class="editor-field">
    <select name="listbox" id="listbox">

        <option value="@(Model.ChosenExercise)" selected="selected">@Model.ChosenExercise</option>

        @foreach (var item in Model.ExerciseName)
        {
            <option value="@item.Name">
                @item.Name
            </option>
        }
    </select>
</div>
