How to pass object as parameter to kendo grid read method - kendo-grid

Question

I have kendo grid as follow.
#(Html.Kendo().Grid<ManualInputDetail>()
.Name("gManualInputDetail")
.Columns(columns =>
{
columns.Bound(c => c.Id).Hidden(true);
columns.Bound(c => c.Month).Title("Month");
columns.Bound(c => c.Value).Title("Value");
})
.Editable(editable => editable.Mode(GridEditMode.InLine))
.Pageable()
.Navigatable()
.Selectable(selectable =>
{
selectable.Mode(GridSelectionMode.Single);
selectable.Type(GridSelectionType.Row);
})
.Sortable(sortable =>
{
sortable.SortMode(GridSortMode.MultipleColumn);
})
.DataSource(dataSource => dataSource
.WebApi()
.Model(model => model.Id(p => p.Id))
.PageSize(12)
.Read(read => read.Url(Url.HttpRouteUrl("ActionApi", new { controller = "ManualInputDetails", action = "GetManualInputDetails" })).Data("getFilterData"))
)
.Pageable(p => p.Refresh(true))
)
using getFilterData function I want to pass object parameter to read method. getFilterData function as follow
function getFilterData() {
var header= {
SectorId: 1,
BrandId: 2,
LocationId: 1,
DataElementId:2
}
return {
header: header
};
}
GetManualInputDataElements method as follow
[ActionName("GetManualInputDetails")]
public DataSourceResult GetManualInputDetails([System.Web.Http.ModelBinding.ModelBinder(typeof(WebApiDataSourceRequestModelBinder))] DataSourceRequest request,ManualInputHeader header)
{
var model = new DataElementMgt().GetAll(header).Select(x => new DataElement()
{
Id = x.Id,
DataElementTypeId = x.DataElementTypeId,
Name = x.Name,
Descriptionn = x.Descriptionn
}).ToList().ToDataSourceResult(request);
return model;
}
In here header value always gives as null. What is the reason for that. Is any thing wrong? Please help..

Answer 1

change the getFilterData method to this
function getFilterData() {
var _header= {
SectorId: 1,
BrandId: 2,
LocationId: 1,
DataElementId:2
}
return {
header: _header
};
}
and it should work. dont use the same name for what you return and declare.
