Currently I group on a hidden field like
GridHelpers.FilterableColumn(columns, m => m.Id).Hidden() .ClientGroupHeaderTemplate(". . . . .");
And as part of the DataSource I added
.DataSource(dataSource =>
{
dataSource
. . . . . .
.Group(g => g.Add(p => p.Id))
;
})
But this seems to alter the way the grid is sorted for display. Is there a hook that I can influence the sorting for the grid?

Our dropdownlist is in a popup editor of a kendogrid.
It has a databound event where we conditionally select the 1st item.
.Events(events => events.DataBound("function() { if (this.value() == '' && this.dataSource.data().length == 1) { this.select(1); } }"))
This works to change the dropdown (and it's hidden input), but when we post back the value is zero.
If we manually select the 1st item then it binds and posts back correctly.
A similar databound event works on other screens, but it just seems to be only a problem the built-in popup editor of the kendo grid.
Any ideas how to get the .select to update the dataItem & post back correctly?

Hello,
I'm using Kendo Grid that displays a set of data based on different filter criteria (Textboxes and DropDownLists values).
I was wondering if using CompositeFilterDescriptor is an ideal way of filtering data instead of using a standard LINQ approach.
Examples provided below.
I've tested multiple queries with Kendo Filtering with lots of criteria and different kind of operators (equal, contains, greaterThan etc..) and everything looks fine. Will I face any limitations with this approach?
The standard LINQ approach:
(Controller)
var query = (from x in products wherex.ProductName == textSearch || x.Model == textSearch || x.Category == dropDownValue|| x.Seller == dropDown2Value|| x.Country == textSearch || x.Description == textSearchselect new Product(){ProductId = x.ProductId,ProductName = x.ProductName,Category = x.Category,Seller = x.Seller,Country = x.Country,Description = x.Description}).ToDataSourceResult(request);
The Kendo Filtering approach:
(Controller)
CompositeFilterDescriptor filterDescriptor = new CompositeFilterDescriptor { LogicalOperator = FilterCompositionLogicalOperator.Or, FilterDescriptors = new FilterDescriptorCollection() { new FilterDescriptor(){Member = "Product", Operator = FilterOperator.IsEqualTo, Value = textSearch}, new FilterDescriptor(){Member = "Model", Operator = FilterOperator.IsEqualTo, Value = textSearch}, new FilterDescriptor(){Member = "Category", Operator = FilterOperator.IsEqualTo, Value = dropDownValue}, new FilterDescriptor(){Member = "Seller", Operator = FilterOperator.IsEqualTo, Value = dropDown2Value}, new FilterDescriptor(){Member = "Country", Operator = FilterOperator.IsEqualTo, Value = textSearch}, new FilterDescriptor(){Member = "Description", Operator = FilterOperator.IsEqualTo, Value = textSearch}, } };request.Filters.Add(filterDescriptor); var query = (from x in productsselect new Product(){ProductId = x.ProductId,ProductName = x.ProductName,Category = x.Category,Seller = x.Seller,Country = x.Country,Description = x.Description}).ToDataSourceResult(request);
Thank you!

I'm looking at using the grid in a generic way with the help of a custom Html Helper.
Is it possible to pass my model to the grid like so @Html.Kendo().Grid(Model) (not like Grid<SomeClass>()) within a partial view without declaring a concrete model such as @model IEnumerable<SomeClass>? Model would be a generic such as IEnumerable<object>, dynamic or find a way to cast it as it's native type in some way.

I have a grid that the datasource shows has data. Exporting the grid to Excel shows data. But the display shows no data in any of the columns. I am not sure how to debug this. Are there some hooks that I can verify that the data is making it to. The column headers show up just no data in each column.
Thank you.

If I specify a column width like
GridHelpers.FilterableColumn(columns, m => m.Description).Width(480);
It seems that the columns that should show to the right are overridden. I don't see them. How do I specify a width AND allow for scrolling?
Thank you.

Right now if an item is grouped the paging doesn't seem to break only on group borders. Say there are 7 items in the group in some cases 4 of the items might be displayed on one page and the rest of the 3 displayed on the next. Is there a way to control the paging so that a "break" only occurs on group boundaries?

Hi,
I am trying to implement 3 level grid following the approach used in Server Hierarchy demo https://demos.telerik.com/aspnet-mvc/grid/serverhierarchy. Is it possible or i should use ClientDetailTemplateId approach?
If it is not possible to use server hierarchy approach for multi level grid then can i use both approaches together? .DetailTemplate for second level and ClientDetailTemplateId for third level.

I'm building an MVC5 web app with a single shared Index view which calls all the associated Editor Templates. It's been working out great until I got to the Kendo Grid.
It seems that the Kendo Grid in InCell or InLine editing is not supported when the grid is inside an editor template. If I do so I'm getting a javascript error Cannot read property '[propname]' of null. Only when I move the grid from its editor template to a standard razor view does it work. I realize that the grid actually fetches its property's editor template but that shouldn't be stopping it as I'm doing the same in other complex elements.
Is there a way this can work with InCell or InLine editing? If not supported, is there a component I can implement/override?

I am not sure what I am missing but I am unable to send an object as a parameter to a controller, the request keep failing with 500 (Internal Server Error).
C# Object:
public class RateQueryDto{ public long WorkHistoryId { get; } public int WorkerId { get; } public int ClientId { get; } public DateTime WeekEndingDate { get; }}
MVC Controller method:
[HttpPost]public ActionResult Read([DataSourceRequest] DataSourceRequest request, RateQueryDto rateQuery){ return Json(true);}
Grid configuration:
@(Html.Kendo().Grid<ConfirmHoursRateModel>() .Name("grid") .HtmlAttributes(new { style = "height:250px;" }) .AutoBind(false) .Columns(columns => { columns.Bound(c => c.Id).Hidden(true); }) .Editable(editable => editable.Mode(GridEditMode.InCell)) .Navigatable() .DataSource(dataSource => dataSource .Ajax() .ServerOperation(false) .Batch(true) .Model(model => { model.Id(w => w.Id); }) .Read(read => read.Action("Read", "ConfirmHours").Data("confirmHoursReadData"))) )
Javascript:
function confirmHoursReadData() { var grid = $("#confirm-hours-grid").data("kendoGrid"); var selectedItem = grid.dataItem(grid.select()); return { WorkHistoryId: selectedItem.WorkHistoryID, WorkerId: selectedItem.WorkerID, ClientId: selectedItem.ClientID, WeekEndingDate: selectedItem.WeekEndingDate };}
