Greetings,

I'm using the Numeric Text Box and I want to limit the number of decimal the user is allowed to enter to a certain value, Let's say 3

I'm seeing the decimals property to 3 and the format to n3

The display is working fine but the user is allowed to input 1.999999 for example and it will be rounded to 2.000

I want it to be 1.999, either by limiting the input or, what I tried to do is forcing the value to be 1.999.

I tried using the onchange event but when the event is fired, the value is already rounded to 2.

 

Any help on this, 

Thanks,

Alex

I need to set an custom empty message for the pager in a listview.  We are binding using data-attributes.  I think the data- for the empty message would be something like this, but this isn't working

 

<div id="pager-#= data.tabId #" class="activity-pane-pager k-pager-wrap" tabindex="0"
             data-role="pager"
             data-bind="source: dataSource"
             data-messages-empty="test message" >
        </div>

 

Can you tell me what this should be?  Thanks!

My grid receives data in JSON format and all dates are in UTC time and formatted to local time using kendo.toString and it works fine.

The problem begins with filters for date time column:

column.filterable = {
            ui: function (element) {
                return element.kendoDatePicker({
                    format: kendoHelpers.dateTimeFormat
                });
            },
            operators: {
                date: {
                    lt: operators.date.lt,
                    gte: operators.date.gte,
                }
            }
        };

 

I will try to explain it on a real scenario:
I'm in UTC+01 timezone and when I want to filter all dates before 27-01-2020 16:30 it correctly saves Date object in grid.filter.filters array (with timezone offset)

but when filter request is being sent to the server it ignores timezone and sends filter:InsertDate~lt~datetime'2020-01-27T16-30-00' (should be 15:30 or with timezone)

 

Is there anyway to modify filter value or change it's format to send also information about timezone?

Hi ,

 I am working on a some prototypes for my workplace and I am looking for guidance on the best approach. I am relatively new to Kendo and have recently switched from the mvc helpers to Jquery + javascript. I am trying to do the following. My sample code is below.

 

1. I would like to dynamically generate the cols on the UI using the remote result set. So the result set may contain 25 cols but I only want to paint 5 of them

2. I would like to implement this in reasonably straight forward manner. I was hoping that I could use the datasource fetch but now am no so sure.

3. I would remove the columnheader menu and install my own drop down in the grid toolbar which I would then use to toggle the grid columns on and off. I could then control what columns this would be performed for.  I have to do this as there is a restriction on using child grids and frozen cols

 

 

The issue that I am encountering is the grid is rendered before I have chance to modify what gets renedered and how. I have seen suggestions that one should destroy the grid prior to rebuilding it.  So can you 

 

A.) Indicate if I should create fetch request outside a datasource and use my custom ajax call or should I rebuild the datasource each request

B.) Destroy the grid at each request 

B.) Do you have any examples in js where this is done. I have search the web and founds bits and pieces. 

 

Thanks

Ciaran

     I have 2 listboxes that are connected. I want to execute a function AFTER an item is transferred from one box to the other. I see the add and remove functionality but it fires before the item is added or removed. I need it to happen after the items are removed from the from box and added to the to box. How would I do this?

Is it possible to just include the kendo.maskedtextbox.min.js in my page? instead of the 3MB kendo.all.min.js file?

What are all the includes needed for maskedtextbox and validation? 

Thanks!

Hi, dev teams!

I have two odata source with data like:

ds1 = [id, title] - unique entities here

ds2 = [id,year,value] - multiples entities

 

I need *title*(ds1) for axeY and *year*(ds2),*value*(ds2) for axeX

So, how i can match this data to one chart by *id*?

Hi,

We are trying to implement Bar/Line charts for our project. We have a specification to remove all extra margins/paddings between titles, labels and plotArea. So far, we could manage to remove for labels and titles but the plotArea still has margins/paddings.

 

 

var options = {
        valueAxis: {
               background: "red",
               title: { text: _getSeriesName(), font: chartFont, margin: 0, padding: 0, visible: IsTitlesVisible, background: "blue" },
               labels: { font: chartFont, margin: 0, padding: 0, background: "green" },
               line: { visible: false }
        },
        series: _getSeries(),
        categoryAxis: {
               background: "red",
               title: { text: _getCategoriesName(), font: chartFont, margin: 0, padding: 0, visible: IsTitlesVisible, background: "blue },
               labels: { font: chartFont, margin: 0, padding: 0, background: "green" },
               categories: _getCategories(),
               line: { visible: false }
        },
        plotArea: { margin: 0, padding: 0, background: "orange" }
};

Please also see the attached file to visualization.
