Grid into Grid Popup Editor - Passing ID parameter in sub grid - asp.net-mvc

Question

I have a Grid with Employes. There is a Edit button and the edit mode is set to Popup. In the EditorTemplate of the entity I want to edit, there is another grid that has a history of Salary with a incell or inline edit mode.
Both grids uses Ajax datasources. The problem is with the inner grid binding. The controller action feeding a Json result to the ajax call requires the ID of the employe we are editing to return the appropriate Salary history. However, Kendo UI ASP.NET MVC wrapper will render some sort of template of the editor before knowing which employee we want to edit, then it will edit it when we are requesting the popup.
How can I feed the Employe ID in the Read Ajax call?
Main Grid
#(Html.Kendo().Grid<MyProject.Business.Models.EmployeDTO>().Name("EmployeGrid")
.ToolBar(toolbar => toolbar.Create())
.Columns(cols =>
{
cols.Bound(o => o.someData).Title("Some Data");
cols.Bound(o => o.moreData).Title("More Data");
cols.Command(o =>
{
o.Edit();
o.Destroy();
}).Title(" ");
})
.Editable(editor => editor
.Mode(GridEditMode.PopUp)
.Window(window => window.Draggable().Resizable().HtmlAttributes(new { #style = "width:700px;" })))
.Sortable()
.Filterable()
.Groupable()
.DataSource(datasource => datasource
.Ajax()
.Model(model => model.Id(o => o.id))
.Read(read => read.Action("GetAll", "EmployesAjax"))
.Update(update => update.Action("Update", "EmployesAjax"))
.Create(create => create.Action("Create", "EmployesAjax"))
.Destroy(destroy => destroy.Action("Destroy", "EmployesAjax"))
)
)
Inner Grid (In Views/Shared/EditorTemplates/EmployeDTO.cshtml)
#Html.Kendo().Grid<MyProject.Business.Models.SalairyDTO>().Name("SalaryGrid")
.Columns(cols =>
{
cols.Bound(o => o.someInfo).Title("Some Info");
})
.DataSource(datasource => datasource
.Ajax()
.Model(model =>
{
model.Id(o => o.id);
model.Field(o => o.employe_id).DefaultValue(Model.id);
})
// NEED THE ID HERE
.Read(read => read.Action("GetByEmployeId", "SalairyAjax", new { id = "" }))
.Update(update => update.Action("Update", "SalairyAjax"))
.Create(create => create.Action("Create", "SalairyAjax"))
.Destroy(destroy => destroy.Action("Destroy", "SalairyAjax"))));

Answer 1

Basically I would suggest you to Set the AutoBind option to false of the inner Grid and use the edit event of the outer Grid to perform a read request and pass the value as additional parameter.
Here is an example:
function onEditOfEmployeGrid(e){
$('#SalaryGrid').data().kendoGrid.dataSource.read({id:e.model.EmployeeID})
}

Answer 2

You could simply pass the value from the grid using addtionaldata parameter within the grid. the RouteID on the (left side) can then be referenced within the Grid Popup Editor using ViewData["RouteID"]. I hope that helps
.Editable(editable => editable.Mode(GridEditMode.PopUp)
.TemplateName("busStop")
.DisplayDeleteConfirmation(true)
.Window(window => window.Modal(true).Resizable().Draggable())
.AdditionalViewData(new { RouteID = Model.RouteID }))
