[Solved] Kendo DateTimePicker - Time appearing up twice in the selection

Hi,

I am facing an issue with the DateTimePicker where the time in the selection box is appearing up twice.Attached is the image.

The code that I have done for round off and for setting the max value is below, please let me know where i am going wrong.

Code snippet -

var currentDate = new Date();

currentDate.setDate(currentDate.getDate() - 28);

currentDate.setMinutes(0);

var startDateTimeElement = $("#start_dateTime");

startDateTimeElement.kendoDateTimePicker({

value: currentDate,

format: "dd/MM/yyyy hh:mm tt",

culture: "en-GB"

});

var endDateTimeElement = $("#end_dateTime");

var endDate = new Date();

//--rounding off the time to the nearest half an hour

var mins = endDate.getMinutes();

var quarterHours = Math.round(mins / 60);

if (quarterHours === 2) {

endDate.setHours(endDate.getHours() + 1);

}

var rounded = (quarterHours * 60) % 60;

endDate.setMinutes(rounded);

//--

endDateTimeElement.kendoDateTimePicker({

value: endDate,

format: "dd/MM/yyyy hh:mm tt",

culture: "en-GB"

});

startDateTimeElement.kendoDateTimePicker({

format: "dd/MM/yyyy hh:mm tt",

culture: "en-GB",

min: currentDate,

max: endDateTimeElement.data("kendoDateTimePicker").value(),

change: function () {

var selectedDate = startDateTimeElement.data("kendoDateTimePicker").value();

endDateTimeElement.data("kendoDateTimePicker").min(selectedDate);

}

});

endDateTimeElement.kendoDateTimePicker({

format: "dd/MM/yyyy hh:mm tt",

culture: "en-GB",

min: startDateTimeElement.data("kendoDateTimePicker").value(),

max: endDate,

change: function () {

var selectedDate = endDateTimeElement.data("kendoDateTimePicker").value();

startDateTimeElement.data("kendoDateTimePicker").max(selectedDate);

}

});

How to get total rows count of kendo ui spreadsheet

I have a Kendo UI Spreadsheet. How do I get the rows count of latest added rows? Say the spreadsheet is empty, I have added data for 2 rows. How do I get the row count. I am using,

var grid = $("#spreadsheet").data("kendoSpreadsheet");
var sheet = grid.sheetByIndex(0);
var data = sheet.toJSON();
var totalRowsCount = data.rows.length;

Here, the totalRowsCount does not always get data rows count and gets total rows that I have defined for my kendo spreadsheet.

Angular Directives in Column Templates

Hello,

We are experiencing high memory usage when using Directives in the grid's column templates.

Due to our business requirement, we have two grids on one page that each contain around 10 columns. There is a lot of different functionality between the grids so the column templates can be pretty complicated (icons for context menus, multiple line content, links..).

In order to implement these features, we thought it would be a good idea to use angular js directives in the kendo grid (using the angular js initialization of the grid of course). We could then proceed to test these directives using jasmine and even import these directives into grids in other pages.

We recently noticed, however, that this uses too much memory (about 450 MB with one grid having 20 rows and the other 120). Each single cell becomes a directive with its own child scope.

Is there any way that you'd recommend for us to create one directive for the entire column not individual cells? Or at least lower the memory usage?

Thank you.

[Solved] TreeView checkbox selection lost on node expand

We are using TreeView which is configured as "loadOnDemand: true" and have checkbox nodes.

In our use case, we need to progmatically select (ticking) matching nodes (which may be present deep inside the hierarchy).

When we try to expand the node, having progmatically ticked nodes which have not loaded earlier, the checkbox selection is getting lost.

http://dojo.telerik.com/@ksingh269/EtaQE

In the above example, on selection of node "Kendo UI Project", another node "Reports>February.pdf" is progmatically ticked. Now when we try to expand node "Reports", the selection is lost.

We are upgrading version from 2015.1 318 to 2016.3.1118 and our project gone through regression cycle. Won;t be possible to move to new build.

Please suggest work around.

I appears to have lost behavior at 2015.3.1111.

Bar Chart, categoryAxis.labels.template, categoryAxis.baseUnit

Hello Team,

I am passing a date object as data source in kendoChart, e.g : { value: 30, date: new Date("Fri Dec 09 2016 10:00:00 GMT+0530 (India Standard Time)") }

When I am giving baseUnit: hours, I am expecting chart to reflect 10:00 on x axis but its giving me half an hour less than the expected one which is 9:30.

Same happens with all the date format I pass as DataSource.

For reference I am attaching a html file, you just have to select hours radio button.

Thanks

KendoUI creates illegal parameter for Mondrian

During testing of a system that uses Mondrian to create database cubes and KendoUI to generate dynamic MDX queries, it seems a cube using "CalculatedMember" is interpreted by KendoUI as "KPI". This is then listed as an item in "FIELDS". However, when clicking on this item, it is stuck in eternal loading while Mondrian logs an error for the query:

ERROR XMLAParser:113 - Method : XMLAResponseParser.parseFaultyResponse(String xmlaResponse), Mondrian Error : The Mondrian XML: No enum constant mondrian.xmla.RowsetDefinition.MDSCHEMA_KPIS

... 20 more

It seems Mondrian does not accept MDSCHEMA_KPIS. During further debugging, it seems KendoUI indeed sends this RequestType "MDSSCHEMA_KPIS":

Request Payload:

<Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/"><Header/><Body><Discover xmlns="urn:schemas-microsoft-com:xml-analysis"><RequestType>MDSCHEMA_KPIS</RequestType><Restrictions><RestrictionList><CATALOG_NAME>LTE</CATALOG_NAME><CUBE_NAME>LTE_10000</CUBE_NAME></RestrictionList></Restrictions><Properties><PropertyList><Catalog>LTE</Catalog></PropertyList></Properties></Discover></Body></Envelope>

Why do KendoUI interpret CalculatedMember as KPI? Why does KendoUI send request for MDSCHEMA_KPIS to Mondrian when this is not accepted?

Difference between KPI and Measure?

Hi, I am curious to learn about the difference between a Measure and a KPI in KendoUI.

Can anyone explain the detailed differences between Measures and KPIs?

Where could I see KendoUI documentation for KPI and Measures? I have tried searching and going through documentation, but nothing seems to mention this.

Bug with centered notifications

Hi,
I recently noticed a bug with the widget of notifications. If you show a centered notification and when is fading you show another one, the second one isn't centered but on the bottom right corner.

You can check this behaviour on the next link:
http://demos.telerik.com/kendo-ui/notification/position-stacking
Click "show centered notification" and when the notification starts to fade away, click again.

I started to notice this behaviour when I updated my kendo version recently. Now i'm using kendo version 2016.1.226.

Thanks.
