我是一个新手,MVC3和剃刀和我需要结合/加载的WebGrid一旦数据从AJAX后返回的帮助。 任何帮助将真正理解(项目截止日期即将到来之际);)
我的情况是这样的:我有两个级联的下拉列表。 第一个列表包含从数据库中的区域。 一旦一个区域中,选择它填充第二个下拉用的设备的清单。 一旦设备被选中,我需要填充的WebGrid有建筑物清单。 我有级联下拉菜单正常工作
Index.cshtml:
@using ThisController = MyProject.Controllers.BuildingModelsController
@model IEnumerable<MyProject.Models.BuildingModel>
<div id="tabs-2">
<!-- Current Buildings -->
@{
if (Model != null && Model.Count() > 0)
{
var grid = new WebGrid(source: Model, rowsPerPage: ThisController.PageSize, ajaxUpdateContainerId: "tabs-2", defaultSort: "BuildingNumber");
grid.Bind(Model, rowCount: Model.Count(), autoSortAndPage: false);
grid.Pager(WebGridPagerModes.All);
grid.GetHtml(
tableStyle: "display",
alternatingRowStyle: "alt",
columns: grid.Columns(
//grid.Column(format: (item) => Html.ActionLink("Edit", "Edit", new { EmployeeID = item.EmployeeID, ContactID = item.ContactID })),
grid.Column("BuildingNumber", header: "Building Number"),
grid.Column("ConstructionDate", header: "Construction Date"),
grid.Column("ExtSquareFeet", header: "Exterior Sq. Ft."),
grid.Column("IntSquareFeet", header: "Interior Sq. Ft."),
grid.Column("IU_Avail", header: "IU Available"),
grid.Column("SpaceAvail", header: "Space Available"),
grid.Column("FixedAssetValue", header: "Fixed Asset Value"),
grid.Column("FixedEquipValue", header: "Fixed Equipment Value")
));
}
else
{
@:There are no buildings at this facility.
}
}
</div>
这里是我的AJAX调用
var regId = $("#ddlRegion").val();
var facId = $("#ddlFacility").val();
$.ajax({
type: "POST",
url: '@Url.Action("GetFacilityDetails")',
data: { regionId: regId, facilityId: facId },
success: function (returndata) {
if (returndata.ok) {
var itemData = returndata.data;
var address = itemData.Address + " " + itemData.City + " " + itemData.State + " " + itemData.Zip;
$("#lblFacilityType").html(itemData.FacilityType);
$("#lblFacilityPurpose").html(itemData.FacilityPurpose);
$("#lblFacilityStatus").html(itemData.FacilityStatus);
$("#lblFacilityAddress").html(address);
$("#tabs").tabs({ disabled: [] });
//need to populate webgrid here
}
else {
window.alert(' error : ' + returndata.message);
}
}
}
);
我的控制器:
[HttpPost]
public ActionResult GetFacilityDetails(int regionId, string facilityId)
{
try
{
//ViewBag.Buildings = buildingsVM.GetFacilityBuildings(regionId, facilityId);
var facility = buildingsVM.GetFacilityDetails(regionId, facilityId);
facility.Buildings = buildingsVM.GetFacilityBuildings(regionId, facilityId) as List<BuildingModel>;
return Json(new { ok = true, data = facility, message = "ok" });
}
catch (Exception ex)
{
return Json(new { ok = false, message = ex.Message });
}
}
@Darin我让你修改建议,但我没有看到屏幕上显示的任何东西。 我没有得到任何错误,无论是。 我通过代码加强和我确认,在视图模型对象有我的自定义“建筑模型”对象12。
这里是我的PartialView:
@model IEnumerable<COPSPlanningWeb.Models.BuildingModel>
@{
if (Model != null && Model.Count() > 0)
{
var grid = new WebGrid(rowsPerPage: 50, defaultSort: "BuildingNumber", ajaxUpdateContainerId: "tabs-2");
grid.Bind(Model, rowCount: Model.Count(), autoSortAndPage: false);
grid.Pager(WebGridPagerModes.All);
grid.GetHtml(
tableStyle: "display",
alternatingRowStyle: "alt",
columns: grid.Columns(
grid.Column("BuildingNumber"),
grid.Column("ConstructionDate"),
grid.Column("ExtSquareFeet"),
grid.Column("IntSquareFeet"),
grid.Column("IU_Avail"),
grid.Column("SpaceAvail"),
grid.Column("FixedAssetValue"),
grid.Column("FixedEquipValue")
));
}
else
{
@:There are no buildings at this facility.
}
}
有趣的是,当我做我看到浏览器中查看源文件“有没有建筑物在这个工厂。”,但它没有被显示在屏幕上和模式确实有我的自定义对象,当我通过代码在调试器阶梯。
