我是MVC3和Razor的新手，一旦从AJAX发布返回数据，就需要绑定/加载WebGrid的帮助。任何帮助将不胜感激(项目截止日期很快临近);)
我的情况是这样的：我有两个级联的下拉列表。第一个列表包含数据库中的区域。选择区域后，它将在第二个下拉列表中填充一系列设施。选择设施后，我需要使用建筑物列表填充WebGrid。我的级联下拉菜单正常工作
Index.cshtml：
@using ThisController = MyProject.Controllers.BuildingModelsController
@model IEnumerable
@{
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.
}
}
这是我的AJAX电话
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;
return Json(new { ok = true, data = facility, message = “ok” });
}
catch (Exception ex)
{
return Json(new { ok = false, message = ex.Message });
}
}
@Darin我已建议您进行更改，但屏幕上未显示任何内容。我也没有任何错误。我逐步检查了代码，并确认视图中的Model对象具有12个自定义的“建筑模型”对象。
这是我的PartialView：
@model IEnumerable
@{
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，当我在浏览器中执行视图源时，我看到“此设施没有建筑物。”，但是它没有显示在屏幕上，并且当我在调试器中逐步执行代码时，模型确实具有我的自定义对象。
