Send DataSourceRequest with JavaScript function

Hello,
I have following grid:

@(Html.Kendo().Grid<Dto.ReportTimeStatDto>()

.Name("ReportGrid")

.Columns(columns =>

{

columns.Bound(c => c.BusinessProcess).Width(100);

columns.Bound(c => c.WorkName)).Width(150);

columns.Bound(c => c.CreationDate).Width(130);

columns.Bound(c => c.TimeLimitDate).Width(130);

columns.Bound(c => c.FinishDate).Width(130);

})

.AutoBind(false)

.Scrollable()

.Resizable(r => r.Columns(true))

.Groupable()

.Sortable()

.Filterable( )

.Pageable(pageable => pageable

.Refresh(true)

.PageSizes(true)

.ButtonCount(5))

.DataSource(dataSource => dataSource

.Ajax()

.Read(read => read.Action("Read", "ReportTimeStat"))

.Model(model => model.Id(m => m.Id))

)

and I have just a simple button:

<button id="statistics" type="button">Statistics</button>

I would like to achieve this scenario:
When user clicks statistics button I would like to pass DataSourceRequest to WebApi Controller. Then I would like to read all data (change pageSize to total count of records) with current filters set on grid and count average value of data from one of the columns.
I have problem with passing DataSourceRequest to my method in controller. I tried sending

$("#ReportGrid").data("kendoGrid").dataSource.filter()

object, but it's a bit different from DataSourceRequest so it's not working.
How could I solve this problem?

[Solved] Kendo theme css overriding existing css

I'm incorporating Kendo ui widgets into an existing application. Unfortunately, the Kendo theme css is overriding other css styles for non kendo widgets.

Is there a way to prevent kendo theme css from doing this?

[Solved] Virtualizing Rows and Columns

Apologies if this has been asked before...

I have a grid where we display a matrix with checkboxes that users can click to check/uncheck items. As long as there aren't ~ > 1000 rows and columns everything is fine. I turned on virtual scrolling like this:

scrollable: { virtual: true }

and like this:

scrollable: { virtual: "rows, columns" }

neither seems to do much when you have 2500 columns and 3000 rows.

Is this even doable? Is there an example of this somewhere I could see?

Kendo grid seems to fire destroy event after create

Hello. I have a very weird issue with Kendo grid. After creating a new record the grid seems to firing a destroy event for some random records. it calls DELETE action on the server that modifies some rows in DB:(sets IsActive field to false, updates ModifyDate and some more rows). I am certain that the delete action is called because of these rows are updated as it is configured in the action. the rows that are being deleted (deactivated) are completely unrelated. has anyone had the similar issue or any ideas how to fix this?

I have attached couple photos. one shows the destroy event configuration, and another one shows database rows, the top ones are deactivated after create event of the bottom row. about 4 to 6 rows are deleted every time.

please let me know if you have some ideas. Thank you in advance

Kendo UI Scheduler (timeline view) and event across midnight

Is there a way to setup Kendo UI Scheduler in timeline view to show a time span across midnight?
If startTime and endTime are in the same day all works fine, if I set two different days it show nothing.

I created two dojo examples. They are different only for startDate and endDate

(working, single day) http://dojo.telerik.com/@purchased.software@deltatre.com/Otale/2

(not working, across days) http://dojo.telerik.com/@purchased.software@deltatre.com/OTUmA

Thanks!
