Questions on Kendo UI for jQuery Forum

Hi folks,

I encountered the following issue: I created a new notification object and it is shown correctly. However, the close icon is missing. The strange thing is the error icon is displayed correctly. I also had a look at the resulting HTML code and this looks fine.

I also checked the WebComponents and KendoUIGylphs font files. I provide these. If I remove them the error icon disappears.

I also had a look inside these files and the keywords "close" and "error" are available.

Do you have any idea what the reason might be?

We use KendoUI 2020.2.617.

Typescript config: target ES6 - broken controls/datasource

After changing the tsconfig.json file to 'target: ES6' our code successfully compiles and runs without errors in the browser.

However, the chart control and the grid control does not display the data from the datasource anymore.

We had a look at the HTML code and the rows for the grid control are created but the data is missing. During debugging we ensured that the read function of our data source delivers the data.

The controls are displayed with the given config. Additionally the specified column names are also not displayed. These also use kendo templates for inserting data.

How to bind Json Data to kendo Line Chart

Here is my code

try

{

if (list != null && list.Count > 0)

{

var serializer = new JavaScriptSerializer();

var hourList = list.GroupBy(x => x.LogDate.Hour).Select(x =>x.First()).Select(x => x.LogDate.Hour);

foreach (var hour in hourList)

{

result.AddRange(list.Where(y => y.LogDate.Hour == hour).Select(y =>

{

var jsonObj = serializer.Deserialize<Dictionary<string, object>>(y.DashboardChartData);

var jsonDoc = new Dictionary<string, object>();

jsonDoc.Add(y.DashboardChartName, jsonObj.ContainsKey("Usage") ? jsonObj["Usage"] : string.Empty);

jsonDoc.Add("LogDateTime", y.LogDate);

jsonDoc.Add("Type", y.DashboardChartType);

var json = JsonConvert.SerializeObject(jsonDoc);

return json;

}));

}

Html.Kendo().Chart()

.Name("datastoreUsageChart" + i)

.Title("DataStoreChart")

.Legend(legend => legend

.Visible(false)

)

.ChartArea(chartArea => chartArea

.Background("transparent")

.Height(300)

)

.HtmlAttributes(new { style = "height:100%; margin-bottom:0px; width:30%; display:inline-block; vertical-align: top; padding-right: 2%;", @class = "chart-small-screen" })

.DataSource(ds => ds.Read(read => read.Action("GetDatastoreChartTotalData", "DashBoard", new { vCenterId = vCenter.vCenterID })))

.Series(series =>

{

foreach (var datastore in tempList)

{

series.Line(datastore).ColorHandler("getColor").CategoryField("LogDateTime").Aggregate(ChartSeriesAggregate.Max);

}

)

.CategoryAxis(axis => axis

.Date()

.BaseUnit(ChartAxisBaseUnit.Hours)

.Min(new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, 0, 0, 0))

.Max(new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, 23, 59, 59))

.MajorGridLines(lines => lines.Visible(false))

)

.ValueAxis(axis => axis

.Numeric()

.Labels(labels => labels.Format("{0}"))

)

.Events(e=>e.DataBound("onDataBoundChart"))

.Tooltip(tooltip => tooltip

.Visible(true)

.Format("{0}-Session")

).ToHtmlString()

Grid Filtered Column with multi option does not update values after datasource.data()

example : https://dojo.telerik.com/ESANeZIt

after you open filter column menu on field1 column the list of checkboxes never changes if you fetch new data.

after investigating, i found that itemchange event datasource['_change']({ action: 'itemchange', items: [] }) refreshes grid filters, but this action breaks listviews bound to datasource.

really is difficult to have custom code for every grid in my application and every datasource.data().

can i expect correct behavior ?

Support for Excel chart import when importing a file into a kendo instance

Currently one can copy an excel chart and paste it into a kendo spreadsheet (as an image). Is there a planned feature that aims to automatically import the charts as well when importing a file?

Virtual Scrolling Issues

I have been having trouble getting virtual scrolling to work correctly with the grid. I am not getting the correct page or skip values when scrolling. This is most noticeable when I scroll to the bottom of the grid. For example, the total number of rows at a particular time was 11973619 but the skip value I got back when scrolling to the bottom was 1342200. So it was not displaying anywhere close to the correct value.

Oddly enough, I still have the last available version of Safari for windows installed and it is the only browser that I have tried where the virtual scrolling works as expected. Chrome, Firefox, and IE all have the same issue described above.

If I turn off virtual scrolling and enable paging it works perfectly in all of the browsers that I have tried. We would really prefer to use virtual scrolling instead of paging though.

I thought maybe it had something to do with some of the rows wrapping and throwing off the calculation using the row height. However, fixing the row height to prevent text wrapping does not appear to make any difference.

Is there something else that I should check that could be throwing off the page calculation?
