Hi, I'm working with DialogFlow and Kendo UI for JQuery and ASP.NET to build a chatbot. I have an issue with the RenderAttachment method. No matter what value (carousel or list or anything else) I give to the AttachmentLayout parameter, the messages are displayed with a list format (Vertical aligned). Is it normal? If not, please can ou help me?

Hi

I'm using kendo stock chart to plot the temperature data of each device. Let's say If I want to plot 5 devices data, I push data to kendo DataSource Object (format of data point: {device_id: <temperature, date: <date>}) as soon as I get data from the device. Initially, I had a limit of 5 devices per a chart but again got a requirement of putting 128 devices. At any point, I used to maintain 10 data points on the chart by removing older data points. But I have increased the limit to 100 data points when plotting 128 device data. After making this change the browser was unresponsive and finally crashes.

1. Is this because of the continuous refreshing of the chart (after pushing the data point, I update the chart using the refresh method)?

2. Or stock chart could not handle more data points?

How to handle updating the chart with continuous data from device efficiently. Could someone provide me with the best practice to do this?

 

I seem to be experiencing an issue with the FilterMenuInit event. I am building and initializing my Grid within a razor view and then binding the events to the grid after initialization.

The problem i am seeing is that the FilterMenuInit is never getting triggered if ColumnMenu(true) is set. If i remove ColumnMenu(true) or set it to false the event is triggered as expected.

I am unsure if this is a bug or if it is something i have configured wrongly.

Hello,

We have a few grids on a page with "filterable: {mode: row}" enabled. This option causes to render a single grid ~700-1000 ms, without this option it takes 10-20 times faster.

Here is example that demonstrates the issue

 

https://dojo.telerik.com/ebavEhos

 

First grid filterable option enabled, the second grid option is not set.

Below the grid, you'll see the time to init each grid.

 

Are there any ways to improve that performance?

 

Thanks,

Max

There have been few discussions on the topic of column minimum widths. And the answers I found so far can be summarized to this:
1. Kendo UI grid does not support min-width for the columns;
2. Developer can set min-width css on the whole grid element;
3. A js function can capture event when user resizes individual column manually and prevent user to go under given width. 

In a most user friendly way the column configuration should have taken column width in % and min-width. 
Are there any plans to implement this feature?

Is there a known function which can work as window.onresize and resize grid columns proportionally with given column min widths? Can min widths be added to columns configuration and then accessed by this function?

Thanks!

Hi,

I want to make a cell editable on double click instead of single click. I know this can be achieved by jQuery. But still do we have any option in kendo grid.

Thanks in Advance,

Hello,

I'm trying to make a success and fail ratio pie chart now.
I have difficulty making label to be shown clearly.

First problem is that the 'outsideEnd' option is not working properly.
With 'outsideEnd', I guess the label should be positioned outside.
But in my case, the label is positioned inside of the pie.

Second, when I tried with 'circle' or 'column' option, the label text overlapping.
I couldn't find other option to arrange it properly.

Would you please kindly help me to do this?

The following my code;

        function createChart() {
          var dataSource = [
            {category: "FAIL", value1: 1970}, 
            {category: "Manual", value1: 8370}, 
            {category: "Automatics", value1: 185000}];

          $("#chart").kendoChart({
            title: { text: "" },
            legend: { position: "bottom", margin: { top: -3, bottom:0 }},
            dataSource: { data: dataSource, datatype: "number" },
            seriesDefaults: { type: "pie", categoryField: "category",
                             labels: {            
                               visible: true,
                               position: "outsideEnd",
                               background: "transparent",
                               //color:"#d9dbe8",
                               template: "#= category #: \n #= value # (#= kendo.format('{0:P}', percentage) #)"
                             }
                            },
            series:
            [
              { field: "value1", name: 'RATIO', overlay: { gradient: "none" }},
              { field: "value2", name: 'PIE_NM'}
            ],
            valueAxis: { format: "{0}%" },
            seriesClick: function(e) {},
            tooltip: { visible: true, 
                      format: "{0}%", 
                      template: "#= series.name #: #= value # (#= kendo.format('{0:P}', percentage) #)", 
                      background: "#2f3b51", 
                      color:"#fff", 
                      border:{width:0}}
          });  
        }

Thanks in advance.

For me, in the latest version of chrome the keyboard shortcuts are not working, even on the documentation example.

https://demos.telerik.com/kendo-ui/datetimepicker/keyboard-navigation

I'm working in MVC 5 and am using Entity Framework.

I want to be able to disable dates in a datepicker where the disabled dates are pulled from a table in the DB, for example the Holidays table where the dates are in a columns called HOLIDAYDATE. I see how to hard code the dates but how do you pull the dates from a data source and load them into the datepicker?

 

Hi,

I've got a MVVM kendo dropdownlist for my single page application that gets rendered with a layout.showIn(), all is fine and the dropdownlist is populated from my viewmodels datasource but the autocomplete filtering always passes null back to my controller method.

 

Controller method:

 

My dropdownlist gets populated fine, but when I try to type in something the autocomplete never gets filtered, upon debugging it turns out that the parameter text is always null it doesn't seem to be passing anything back to the GetEventCodes controller method. Am I missing something here? I've looked at the demos and documentation and it doesn't seem like I'm missing anything.

Side Note: I can't seem to get my templates to render when I move the script/templates to another location e.g. remove it locally, I want to have a separate .cshtml file preferably that will have all my templates and I can call that from my javascript file instead of having it all in one file which creates a lot of clutter.

Thanks.
