Question

好的，我在这里结束了。我查看并复制了我能找到的每个例子，但没有任何作用。这是我的设置

控制器操作：

public async Task<IHttpActionResult> GetRecipeOData(ODataQueryOptions<Recipe> queryOptions)
        {
            // validate the query.
            try
            {
                queryOptions.Validate(_validationSettings);
            }
            catch (ODataException ex)
            {
                return BadRequest(ex.Message);
            }


            RecipeContext rc = new RecipeContext();            

            return Ok<IQueryable<Recipe>>(rc.Recipes.AsQueryable());
            //return StatusCode(HttpStatusCode.NotImplemented);
        }

Kendo Grid：

var initRecipesGrid = function () {
            $("#recipesGrid").kendoGrid({
                dataSource: {
                    type: "odata",
                    transport: {
                        read: "odata/RecipeOData",
                    }
                },
                height: 550,
                groupable: true,
                sortable: true,
                pageable: {
                    refresh: true,
                    pageSizes: true,
                    buttonCount: 5
                },
                columns: [{
                    field: "Label",
                    title: "Recipe Name"
                },{
                    field: "OriginalGravity",
                    title: "O.G."
                },{
                    field: "FinalGravity",
                    title: "F.G."
                }]
            });
        }

以下要求：

GET http://localhost:25189/odata/RecipeOData?$callback=jQuery21109926259643398225_1405994583958&%24inlinecount=allpages&%24format=json

}

我在dataSource中添加了一个“错误”函数，我记录了错误。我得到以下内容：

object {xhr: Object, status: "parsererror", errorThrown: SyntaxError, sender: ct.extend.init, _defaultPrevented: false…}
_defaultPrevented: false
errorThrown: SyntaxError
message: "Unexpected token :"

我的DataSource配置嵌套错误。我需要它看起来像这样：

transport: {
    read: {
        url:"odata/RecipeOData",
        dataType: "json"
    }

Kendo Grid无法使用OData Controller
