Kendo Form for ASP.NET Core - custom editor for a form field

Hello,

I'm looking for a way to create a custom editor for a field in a Kendo Form.

I've created a partial view in my Shared/EditorTemplates folder. Also, I've applied the UIHint attribute with the name of the partial view on the property of my view model. But still it does not render as expected, the view does not show up on the form.

Is there any demo on how to do this. I really tried to search, but was not able to find something for this exact case.

Thanks!

How to make recurrence exceptions work with multiple timezones

I have a recurring event with exceptions in one timezone and am trying to display the schedule in another timezone.

The events all display correctly with corresponding daylight saving adjustments however the exceptions get lost once the event timezone transitions into (or out of) summer time.

Running following code in the dojo correctly hides the 17th of April occurrence IF the timezone is set to "Europe/London" but displays the entry when set to "Pacific/Auckland".

TreeList new row disappears on edit

I have a TreeList control where the data is kept in an array in memory - the user will save manually after editing everything they need to.

One problem I'm facing is that if a new record is created, and then subsequently edited - it will disappear after either Save or Cancel.

I've removed a lot of the code for brevity - but this is a working example of what I have:

https://dojo.telerik.com/tDidtCqZ

Any idea what I'm doing wrong?

Prevent dialog from closing if action is an async function

As the title already says, if I setup a button dialog with an action that is an async function, returning false does not prevent the dialog from closing after triggering the action. Is there any workaround for this behaviour?

Add class to marker in Jquery ScatterPlot Chart

I have a kendo UI Jquery scatterplot chart with markers of type: square and rotation: 45. I'm trying to add a class based on the series to the markers so that certain ones can be styled to have a pointer when the user mouses over them. I found a few Google AI answers but they seem to be wrong. Here is what I tried where chartData is set to my series option on initialization.

Update: I added the class manually in dev tools and it still doesn't trigger the pointer to appear. This seems to be due to there being a separate marker that Kendo is creating in the DOM for the hover event which does not get the class. I need to add a cursor: pointer; style to that element

        chartData.push({
            name: legendSeriesName,
            xField: "x",
            yField: "y",
            data: storeDetailScatterPlotData
                .filter(d => d.seriesName === seriesName && d.accountId === storeDetailAccountId)
                .map(d => ({ x: d.sales, y: d.storeAmt, storeName: d.storeName, storeId: d.storeId, accountId: d.accountId })),
            zIndex: 10 - index,
            color: seriesColor,
            markers: {
                border: seriesColor,
                background: seriesColor,
                type: "square",
                rotation: 45,
                visual: function (e) {
                    var series = e.series.name;
                    var defaultVisual = e.createVisual();
                    defaultVisual.options.attr("class", series);
                    return defaultVisual;
                }
            }
        });

Updating parent data grid from child grid

Hello

I have a grid and each row can be expanded, using detailInit, to show an inner grid.

I fetch the data beforehand so that I can populate the grid using local data.

In inner grid I have a column with a delete button - using template I call a delete function passing this as a parameter.

// column definition
 {
                    field: "delete",
                    title: "Delete",
                    width: 50,
                    template: "<span class='delete' onclick='delete(this)'><img src='.delete_icon.png'/></span>"
},

my delete function :

function delete(e) {
            let Loader = KENDO.KendoLoader($("body"));
            try {
                Loader.Show();
                let row = $(e).closest("tr");
                let grid = $(e).closest(".innerGrid");

                let dataItem = KENDO.KendoGrid(grid).GetDataItem(row);
                let innerRowId= dataItem.id;

                let parentRow = row.parent().closest(".k-detail-row").prev();
                let parentDataItem = KENDO.KendoGrid($("#ParentGrid")).GetDataItem(parentRow);

                KENDO.KendoGrid(grid).DeleteUI([innerRowId]); // DeleteUI gets array of ids to delete , implemented below
               
                // if no rows remain in inner grid, I need to update a column's value in the parent row
                if (KENDO.KendoGrid(grid).HasRows() == false) {
                    grid.hide();
                    grid.siblings(".noRecordsFound").show();

                     let updatedDataObj = {
                            id: parentDataItem.id,
                            someColumnOnParentRow: null
                        }

                        KENDO.KendoGrid($("#ParentGrid")).UpdateUI([updatedDataObj]); // UpdateUI gets array of objects to update, implemented below
                }
            }
            catch (error) {
                debugger;
                console.log(error.message);
            }
            finally {
                Loader.Hide();
            }
        }

We have created a own KENDO wrapper script for different widgets. Here is the kendoGrid code:

let KENDO = {
  KendoComponent(jQueryElement, component, options = null) {

        let kendoComponent = {};

        kendoComponent.InitKendoComponent = function () {
            let kComponent = jQueryElement.data(component);
            if (!kComponent) {
                if (options) {
                    kComponent = jQueryElement[component](options).data(component);
                }
                else {
                    kComponent = jQueryElement[component]().data(component);
                }
            }
            return kComponent;
        };

        return kendoComponent;
    },

   KendoGrid(jQueryElement, options = null) {

        let kendoGrid = {};

        let kGrid = KENDO.KendoComponent(jQueryElement, "kendoGrid", options).InitKendoComponent();
        if (options)
            kGrid.setOptions(options);

        kendoGrid.SetOptions = function (options) {
            kGrid.setOptions(options);
            return kendoGrid;
        }

        kendoGrid.GetData = function () {
            return Array.from(kGrid.dataSource.data());
        }

        kendoGrid.GetDataItem = function (jQueryTableRow) {
            return kGrid.dataItem(jQueryTableRow);
        }

        kendoGrid.UpdateUI = function (dataToUpdate = []) {
            dataToUpdate.forEach(obj => {
                let dataItem = kGrid.dataSource.get(obj.id);
                if (dataItem) {
                    for (let prop in obj) {
                        if (prop !== "id") {
                            dataItem.set(prop, obj[prop]);
                        }
                    }
                } 
            });
            return kendoGrid;
        }

        kendoGrid.DeleteUI = function (idsToDelete = []) {
            idsToDelete.forEach(id => {
                let dataItem = kGrid.dataSource.get(id);
                if (dataItem)
                    kGrid.dataSource.remove(dataItem);
            });
            return kendoGrid;
        };

        kendoGrid.HasRows = function () {
            return kGrid.dataSource.data().length > 0;
        }

        return kendoGrid;
    }
  
}

It appears that UpdateUI does not function as it should.

When I test I notice that when the last remaining row of inner grid is deleted, the parent row's column is indeed updated to null, the No Records Found message is shown instead of the inner grid, the parent row gets collapsed, and when I expand it the inner grid is shown with the last remaining row.

Suprisingly, if I comment out the UpdateUI line, the inner grid's row gets deleted, without collapsing the inner grid and the No Records Found message is shown as intended (the parent row's column does not get updated in this case, obviously).

Is it a bug in Kendo ? or am I doing something wrong?
