DropDownList with dynamic parameter in DataSource

[Anton.S]

Greetings!

 

I've implemented an EditorTemplate that uses Kedno.DropDownList for one of the model properties. Here is an example of it

1.@(Html.Kendo().DropDownList()
2.          .Name(ViewData.ModelMetadata.AdditionalValues["id"].ToString())
3.          .OptionLabel("not selected")
4.          .DataTextField("Name")
5.          .DataValueField("Id")
6.          .DataSource(ds => ds.Read(a => a.Action("GetAvailiableOrders","Orders")))
7.          .Filter(FilterType.Contains)
8.

I use this model to populate grid, like so

01.@(
02.    Html.Kendo().Grid<CustomerViewModel>()
03.    .Name("customersGrid")
04.    .ToolBar(toolbar =>
05.    {
06.        if (!Model.ReadOnly)
07.        {
08.            toolbar.Create();
09.        }
10.    })
11.    .Editable(e => e.Mode(GridEditMode.InLine).CreateAt(GridInsertRowPosition.Bottom))
12.    .Resizable(resize => resize.Columns(true))
13.    .Columns(c => {
14.        c.Bound(s => s.Order); //EditorTemplate will be used here
15.        c.Bound(s => s.ConsumerName).Format("{0:dd.MM.yyyy}");
16.        c.Bound(s => s.OrderDate).Format("{0:dd.MM.yyyy}");
17.        if (!Model.ReadOnly)
18.        {
19.            c.Command(command =>
20.            {
21.                command.Edit();
22.                command.Destroy();
23.            });
24.        }
25.    })
26.    .DataSource(d => d.Ajax().
27.    Model(m =>
28.    {
29.        m.Id(p => p.Id);
30.        m.Field(p => p.Id).DefaultValue(default(long));
31.    })
32.    .Read(a => a.Action("GetCostumers","Costumers"))
33.    .Create(a => a.Action("CreateCostumer", "Costumers"))
34.    .Update(a => a.Action("UpdateCostumer","Costumers"))
35.    .Destroy(a => a.Action("DeleteCostumer", "Costumers"))
36.    )
37.)

I need some how to pass additional argument to the DataSource Read method,this parameter depends on other model property an is uiniqe for each grid row.

.DataSource(ds => ds.Read(a => a.Action("GetAvailiableOrders","Orders"))) //Need to pass additional argument here dependting on current row

Is there any way to implement this?

Hello Anton,

Please see the following thread, which shows the available ways to pass parameters and how to access the data in the controller.
