Send Additional Parameter in Kendo Grid Read Action

问题:

I have a kendo Grid as follows.

@(Html.Kendo().Grid()      .Name("WeeklyRevenue")      .Resizable(resizing => resizing.Columns(true))      .Columns(columns =>          {             columns.Bound(p => p.Number).Width(100);             columns.Bound(p => p.Type).Width(100);             columns.Bound(p => p.Week1).Format("{0:c}");             columns.Bound(p => p.Week2).Format("{0:c}");             columns.Bound(p => p.Week3).Format("{0:c}");             columns.Bound(p => p.Week4).Format("{0:c}");             columns.Bound(p => p.Week5).Format("{0:c}");             columns.Bound(p => p.TotalRevenue).Format("{0:c}");          })      .Scrollable()      .Events(events => events.Change("onChange").DataBound("onDataBound"))      .DataSource(dataSource => dataSource.Ajax().Read(read => read.Action("WeeklyRevenue", "Home")).ServerOperation(false))      .Pageable(pager => pager.Refresh(true))  )

Here is my Controller code

public ActionResult WeeklyRevenue([DataSourceRequest]DataSourceRequest request)         {             ...             DataSourceResult result = res.ToDataSourceResult(request);             return Json(result, JsonRequestBehavior.AllowGet);         }

It works fine. But I want to send additional data when Grid reads data, something like the following;

public ActionResult WeeklyRevenue([DataSourceRequest]DataSourceRequest request, string AdditionalParam)

I couldn't find any solution how to do this. Thanks in advance.

回答1:

If the additional data is known at server-side you should use the overload of the Action method which accepts route values:

.DataSource(dataSource => dataSource.Server()    .Read(read => read.Action("Read", "Home",          new { AdditionalParam = ViewData["AdditionalParam"] })) )

If this additional data is known at the client-side only you should use the Data method:

.DataSource(dataSource => dataSource.Ajax()    .Read(read => read       .Action("Read", "Home")       .Data("additionalData")   ) )

You can try this;

.Read(read => read.Action("WeeklyRevenue", "Home", new { AdditionalParam = "Test" }))

Or via JavaScript function;

.Read(read => read.Action("Products_Read", "Grid").Data("additionalInfo"))  function additionalInfo() {     return {         AdditionalParam : "test"     } }

Or full JavaScript;

transport: {     read: {       url: "/Home/WeeklyRevenue",       type: "POST",       contentType: "application/json",       dataType: "json",       data: {         AdditionalParam : "Test"        }     }   }

If you use parameterMap make sure you stringify like following:

parameterMap: function (data, operation) {                     if (operation != "read") {                         return kendo.stringify(data.models);                     }                     else if (operation === "read") {                         return kendo.stringify(data);                     }                 }

In controller something like this

public ActionResult Products_Read([DataSourceRequest] DataSourceRequest request, string AdditionalParam) {...}

Further documentation can be found in here and here.

We can use options given below to pass additional parameters.

//object route values Read(read => read.Action("vs_Read", "vs", new{id=33})  //js function name Read(read => read.Action("vs_Read", "vs").Data("passAdParam")  //By Template Delegate Read(read => read.Action("Aggregates_Read", "Grid").Data(@             function() {                 //pass parameters to the Read method                 return {                     name: "test",                     id: $("#search").val()                 }             }               ))

In my case : I have a input type text, and I want my grid load data with filter from my text input, and the grid will load data when I press btnSearch:

@(Html.Kendo().Grid()                 .Name("gridUsers")                 .Columns(columns =>                 {                     columns.Bound(c => c.Code);                     columns.Bound(c => c.LanID);                     columns.Bound(c => c.DepartmentName);                     columns.Bound(c => c.UserRole);                     columns.Bound(c => c.Level);                 })                 .DataSource(dataSource => dataSource                     .Ajax()                     .Read(read => read.Action("GetUserSample", "ApprovalManager").Data("filterLanID"))                     .PageSize(20)                 )             )  

An the controller :

public ActionResult GetUserSample([DataSourceRequest]DataSourceRequest request, string lanid)         {             IEnumerable userModel = GetListUser(lanid);             return Json(userModel.ToDataSourceResult(request));         }
