Hi Guys
I have been using the technique as outlined in the 'How To' article 'Sort Multiple Checkbox Filter'
to sort the data prior to showing the filter menu.
This works fine when called from filterMenuInit but I can see this event is not fired when using Column Menus.
Moving the code into the columnMenuInit event results in an
Uncaught TypeError: Cannot read property 'data' of undefined
when executing the following statement
var filterMultiCheck = this.thead.find("[data-field=" + e.field + "]").data("kendoFilterMultiCheck")
I have trawled through the How To articles and forums looking for a solution to the problem but have so far drawn a blank.
Therefore any help would be much appreciated.
Regards
Alan

The calendar scheduler date range binding doesn't apply to calendar view. On edit, I see the start and end date as a correct multi-day event, but on save the calendar view doesn't get updated with multi-day event range.
I do have all the fields similar to example https://demos.telerik.com/kendo-ui/scheduler/index

I'm using Custom Binding via AJAX to sort my data source.
The grid columns do not show any sort indicators.
In contrast, when not doing custom binding but let Kendo UI handle it, sort indicators are being displayed.
My question:
How can I tell the grid columns to show sort indicators, even if I'm using custom binding?

Hello,
We are using a column chart similar to your demo of:
https://demos.telerik.com/kendo-ui/bar-charts/column
In this demo the tooltips always appear to the left/right side of the hovered column. Is there a way to set the tooltip location so it will be presented above the column (i.e. column top)?
Thanks,
Ron.

I'm using the diagram tool for visually displaying a workflow and having a problem with overlapping labels when the connectors are bi-directional. So for example, if I have 2 nodes (A & B) and A connects to B and B connects to A, the connectors work correctly but the labels overlap. I'm using a connectionsDataSource so don't really have a lot of control over configuring the connectors in-line. I'm using a numeric ID for the individual nodes so I should be able to tell if it's a backwards connection, I'm just not sure where to start and how to change where the connectors connect (e.g. the bottom of the item(s) instead of the side.

Steps to reproduce:
Go to https://docs.telerik.com/kendo-ui/controls/scheduling/scheduler/how-to/editing/modify-editor-when-event-is-new
Click "Open in Dojo"
Click Run
Doubleclick any free slot different from today day (e.g. click on Thursday if today is Monday)
In the open popup select Repeat=Weekly
Actual Result: Monday checkbox is checked by default
Expected behavior: Thursday is checked by default because of is created for Thursday
The same issue is reproducible when selecting other Repeat options
In the open popup from the previous steps select Repeat=Daily
Pay attention to "On" option value
Actual Result: On option says 1/7/2019
Expected behavior: 6/13/Y is selected in default option because of selected date for the event 6/13/2013

I am using a line series grouped on year so i get a series for each year. The data comes across from the read looking something like this for each data point
{Key: X, Year: 2013, Month: 11, Value: 100}
{Key: X, Year: 2013, Month: 12, Value: 120}
{Key: Y, Year: 2013, Month 11, Value: 200}
{Key: X, Year: 2014, Month 1, Value: 100}
{Key: Z, Year: 2013, Month 11, Value: 200}
The datasource is defined as:
So depending on what filters the user chooses, I update the filters on the data source so it could show combined data from any subset of the Keys. The Series is defined as...
The problem is that there are no data points for the months 2-12 in year 2014, but despite having it set to show missing points as a gap, it shows up as zero's on the chart. However, If I don't use the aggregate and only show the values for one Key then the missing points in 2014 are correctly shown as gaps. Is this an unavoidable consequence of using the Aggregate, or is there a way to get it to not show points for which the aggregate is NULL instead of treating it as a 0?
{Key: X, Year: 2013, Month: 11, Value: 100}
{Key: X, Year: 2013, Month: 12, Value: 120}
{Key: Y, Year: 2013, Month 11, Value: 200}
{Key: X, Year: 2014, Month 1, Value: 100}
{Key: Z, Year: 2013, Month 11, Value: 200}
The datasource is defined as:
.DataSource(ds => ds .Read("_getAllData", "Data") .Group(gg => gg.Add(m => m.Year)) .Filter(ff => ff.Add(m => m.Key).IsEqualTo("X").Or().IsEqualTo("Y")) .Sort(ss => { ss.Add(m => m.Year).Ascending(); ss.Add(m => m.Month).Ascending(); }))So depending on what filters the user chooses, I update the filters on the data source so it could show combined data from any subset of the Keys. The Series is defined as...
series.Line(m => m.Value, m => m.Month)
.Aggregate(ChartSeriesAggregate.Sum).MissingValues(ChartLineMissingValues.Gap);The problem is that there are no data points for the months 2-12 in year 2014, but despite having it set to show missing points as a gap, it shows up as zero's on the chart.

Is it possible to have multiple validator initializations on different div tags? Basically I'm wanting to do a wizard (without the use of the progress bar) and I want to validate one div tag per "next" button.
function ShowSection2()
{
//validation
var validator = $("#Section1").kendoValidator().data("kendoValidator");
if (!validator.validate())
{
return;
...
function ShowSection3()
{
//validation
var validator = $("#Section2").kendoValidator().data("kendoValidator");
if (!validator.validate())
{
return;
...

Using R3 2018 SP1.
I need to bind to the select event using MVVM in order to prevent some nodes from being selected. I've modified the MVVM demo code to bind to the select event and I'm unable to get it working. Is this a known issue? Is there a workaround that I can use which uses MVVM?
Thanks
