Anyone know if offlineStorage would let users scroll through previous pages that were loaded via virtual scrolling? Can they come back to a page that was closed and see their cached data? Is there a feature that would allow this?

How to prevent detailCollapse event on kendo grid (jquery)?

I created a grid with detail rows. Detais rows may have unsaved data. In that case I need to stop the collapse event. My code is not working:

var detailGrid = $("#grid-details").kendoGrid({
detailTemplate: getDetailTemplate,
detailInit:InitFunc,
detailCollapse: function (e) {
if (.....here I check for changes ) {
e.preventDefault();
return false;

}
},

......});

I got to e.preventDefault(), but the row is collapsed anyway

Hide column based on values of footer

I was wondering how to hide/show columns based on the values of aggregate values in footer. For example:

@(Html.Kendo().Grid<Payroll.Models.PayrollAuthorizationByDepartmentModel>()
.Name("Grid")

.Columns(columns =>
{
columns.Bound(dataSource => dataSource.EmployeeId).Title("Emp. No");
columns.Bound(dataSource => dataSource.EmployeeNameForDisplay).Title("Emp. Name");
columns.Bound(e => e.RegHours).Title("Reg.")
.ClientFooterTemplate("<div style='text-align: right'> \\#= kendo.toString(sum, '0.00')\\# </div>")
.ClientTemplate("\\#= kendo.toString(RegHours, '0.00')\\#");
columns.Bound(e => e.OTHours).Title("OverTime 1.5")
.ClientFooterTemplate("<div style='text-align: right'> \\#= kendo.toString(sum, '0.00')\\# </div>")
.ClientTemplate("\\#= (OTHours==0)? '':kendo.toString(OTHours, '0.00')\\#");
                        })
.DataSource(dataSource => dataSource
.Ajax()
.Aggregates(aggregates =>
{
aggregates.Add(e => e.RegHours).Sum();
aggregates.Add(e => e.OTHours).Sum();
                                                          })
.Read(read => read.Action("AuthorizationByEmployee_Read", "Authorize", new { locationId = @ViewBag.LocationId, departmentId = "#=DepartmentId#", startDate = @ViewBag.StartDate, endDate = @ViewBag.EndDate }))
.ServerOperation(false)
.Sort(sort => sort.Add("EmployeeFirstName").Ascending())
)
.Sortable()
.Events(events => events.DataBound("onDataBoundOfChildGrid"))
.ToClientTemplate()
)

How to hide the column if the sum is 0?

Thanks!

Simple Bar chart

I am having some trouble with a simple bar chart.

Here is my model

public class PrivateReportCardCumulativeInvestments

{

public int FUND_INT { get; set; }

public int YearCategory { get; set; }

public decimal Commitments { get; set; }

public decimal Distributions { get; set; }

public decimal Draw_Down { get; set; }

public decimal Fees { get; set; }

public PrivateReportCardCumulativeInvestments()

{

}

And here is my Chart.


    @(Html.Kendo().Chart<BetaSMTRApp.Business.PrivateReportCardCumulativeInvestments>()
                                .Name("ChartInvestmentCumulations_" + item.FUND_INT.ToString())
                                .Title("Cumulative Investments")
                                .DataSource(dataSource => dataSource
                                                .Read(read => read.Action("GetCumulativeInvestments", "PrivateReportCard", new { fundInt = item.FUND_INT }))
                                              )
 
                                .Series(series =>
                                {
                                    series.Column(model => model.Commitments).Name("Commitments");
                                    series.Column(model => model.Distributions).Name("Distributions");
                                    series.Column(model => model.Draw_Down).Name("DrawDowns");
                                    series.Column(model => model.Fees).Name("Fees");
                                })
                                .Legend(legend => legend
                                    .Position(ChartLegendPosition.Bottom)
                                )
                                .ValueAxis(axis => axis.Numeric()
                                    .Labels(labels => labels
                                        .Format("${0}")
                                        .Skip(2)
                                        .Step(2)
                                    )
                                )
                                .CategoryAxis(axis => axis
                                    .Categories(model => model.YearCategory)
                                    .Labels(labels => labels.Format("yyyy"))
                                )
)

Looking for the following result

Vertical Axis (value of the following)... model.Commitments, model.Distributions, model.DrawDown, Model.Fees (values are between 0 and 3 as a decimal with 1 precision.

Horizontal Axis (model.YearCategory)

Bars -- Commitment, Distribution, DrawDown and Fees.

Example of data

YearCategory Commitments Distributions Draw_Down Fees

2004 71.5 36.5 0 0.5

2005 35.8 50.6 6.4 2

2006 0 90.9 28 4

2007 0 111.7 43.2 5.7

2008 0 110.4 50.5 8.1

2009 0 113 59.3 9.8

2010 0 113.7 81.2 11.2

2011 0 111 88.3 12.7

2012 0 74.6 146.4 14

2013 0 76.5 153.6 15.1

2014 0 41.9 252 16.3

Any ideas of what i am missing?

Thanks

Fill child grid from parent on Edit event (new)

I have a nested grid that when I am adding a new child, I would like the input for the new child to be filled based on a column from the parent.
Basically I need to get reference to the data object for the parent of the child. I am not sure how to traverse the node structure to go all the way to the parent and get a column. (2 input columns and a mulltiselect column),

the edit event has the following according to the docs

Kendo Window undefined

Hi!
I would like to say that i have already read similiar topics in this forum and none of them solved my problem. When im trying to access dynamically created window data("kendoWindow") the result is undefined :/

So i've got a "Contractors" View which got almost nothing inside it, besides kendo Grid and few buttons + this placeholder:

<div id="editContractorNaturalPersonWindow"></div>

When a user clicks the button, window is opened:

$(".contractorNaturalPerson").click(function () {

var dataUrl = $(this).data("url");

$("#editContractorNaturalPersonWindow").kendoWindow({

content: {

title: "title123",

url: dataUrl

},

open: function () {

kendoWindow_center("#editContractorNaturalPersonWindow");

},

refresh: function () {

kendoWindow_center("#editContractorNaturalPersonWindow");

}

});

var dialog = $("#editContractorNaturalPersonWindow").data("kendoWindow");

dialog.open();

});

Till now everything works, window is being opened, centered, etc. Inside dynamically loaded "EditContractorNaturalPerson" Partial View i've got a simple form with few textboxes and this script:

$('.editContractorNaturalPersonForm').submit(function () {

if ($(this).valid()) {

$.ajax({

url: this.action,

type: this.method,

data: $(this).serialize(),

success: function (data) {

if (data.result == "Success") {

debugger;

var dialog = $("#editContractorNaturalPersonWindow").data("kendoWindow");

dialog.close();

$('#contractorsGrid').data('kendoGrid').dataSource.read();

return false;

}

else if (data.result == "Error") {

debugger;

for (prop in data.modelErrors) {

if (data.modelErrors[prop].length > 0) {

$("#" + prop).next().text(data.modelErrors[prop]);

}

},

error: function (xhr, ajaxOptions, thrownError) {

alert("EditContractorNaturalPerson-AjaxError");

}

});

}

return false;

});

This line:

var dialog = $("#editContractorNaturalPersonWindow").data("kendoWindow");

Gives me undefined, EVEN THAT jQuery found this object:

$("#editContractorNaturalPersonWindow")

I already tried to remove window by destroying this jquery object (k-window) but it breaks its functionality. What can i do ? Please help :)

Split/Capitalize Auto Generated Column Titles

Hi,

I have probably missed something really obvious, but I just can't seem to find the right property.

I have a Grid bound to an OData source from which I am auto generating the columns. When this happens the column titles are not split around capital letters so they are readable unlike when they are bound individually. I tried using a column build action to set the titles of the columns, but it doesn't seem to work... unless I am doing something not quite right.

A bit of example code here (I have just tried to change the column name to a set value, but it doesnt work when I try to split the column member name either)

@(Html.Kendo().Grid<dynamic>()

.Name(Model.Name)

.Columns(columns =>

{

//columns.AutoGenerate(true);

//columns.AutoGenerate(col => col.Title = col.Member.SplitPascalCase());

columns.AutoGenerate(col => col.Title = "COLUMN NAME");

})

.DataSource(dataSource => dataSource

.Custom()

.Type("odata")

.Schema(schema =>

{

schema.Data("value")

.Total

(

@<text>

function total(data)

{

return data["odata.count"];

}

</text>

);

})

.Transport(transport =>

{

transport.Read(read => read.Url(Model.ODataPath).DataType("json"));

}

)

.PageSize(Model.PageSize)

.ServerPaging(true)

.ServerSorting(true)

.ServerFiltering(true)

)

thanks,

Rob

Sub-grid No Records Found not appearing

Hello,

We are updating a project to the most recent release (2015.3.930), pretty much specifically to fix the whole "No records found" scenario. Currently we use the javascript method people have come up with, putting a setTimeout on the DataBound event of the grid, but this is pretty unreliable and as such, when the official No Records Found came out, we would prefer to use that.

It seems however that in our most unreliable case (a nested grid, 5 levels down, business requirement), the now-built-in NoRecords is not working at all. It works fine on single level grids, but in this instance, when the grid is a Client Template (using .ToClientTemplate() - we use the fluent API for MVC), it doesn't do anything.

I thought maybe it was because we had Pageable disabled (.Pageable(paging => paging.Enabled(false))) and so there was no footer, but even enabling this didn't make it work. The footer correctly detects that there are no items found (as it displays that default message in the bottom right corner), but the .NoRecords("No Records Found!") does not render in the grid, or in the DOM at all.

The below is what gets rendered, which has no message for the no records found.
