将远程数据绑定到 kendo 树视图
Binding remote data to kendo treeview
我试图 return 我从控制器操作方法获得的值到 kendo 树视图,以将模块名称 pupulate 为 kendo 树视图中的父节点。
public ActionResult LoadTreeView([DataSourceRequest] DataSourceRequest request)
{
using (var countryvar = new TGSFMSSys_UserEntities())
{
IQueryable<Module> module = countryvar.Modules;
DataSourceResult result = module.ToDataSourceResult(request, value => new Module
{
ModuleId = value.ModuleId,
ModuleName = value.ModuleName
});
return Json(result, JsonRequestBehavior.AllowGet);
}
}
下面是我创建的 kendo 树视图的 Javascript 代码
<script>
$("#treeview").kendoTreeView({
checkboxes: {
checkChildren: true
},
check: onCheck,
dataSource:
{
transport: {
read: '/MapModuleTask/LoadTreeView'
}
},
dataTextField: 'ModuleName'
});
</script>
请尝试使用以下代码片段。
控制器:HomeController.cs
public JsonResult LoadTreeView(int? id)
{
List<Module> modules = new List<Module>();
int temp = id.GetValueOrDefault();
modules.Add(new Module() { ModuleId = 1 + temp, ModuleName = "Name1_" + temp , hasChildren = false });
modules.Add(new Module() { ModuleId = 2 + temp, ModuleName = "Name2_" + temp, hasChildren = true });
return Json(modules, JsonRequestBehavior.AllowGet);
}
型号:
public class Module
{
public int ModuleId { get; set; }
public string ModuleName { get; set; }
public Boolean hasChildren { get; set; }
}
视图:
<div id="treeview"></div>
<script>
var datasource = new kendo.data.HierarchicalDataSource({
transport: {
read: function (options) {
var id = options.data.ModuleId;
$.ajax({
url: '/Home/LoadTreeView',
dataType: "json",
data: { id: id },
success: function (result) {
options.success(result);
},
error: function (result) {
options.error(result);
}
});
}
},
schema: {
model: {
id: "ModuleId",
hasChildren: "hasChildren"
}
}
});
$("#treeview").kendoTreeView({
checkboxes: {
checkChildren: true
},
dataSource: datasource,
dataTextField: 'ModuleName'
});
</script>
如有任何疑问,请告诉我。
