Diagram Refresh

I have a diagram configured that reads data from an MVC Controller. It displays and works fine. I need to do a long poll and refresh the diagram from the database. I have tried all kinds of things.

Called refresh on the diagram object, called read on the datasource.

What is the proper way to get a Diagram to read the data again and redraw itself.

setOptions on numericTextBox locks spinner

When calling setOptions on the numericTextBox, the spinner locks up if there is a "factor" option set.

https://dojo.telerik.com/OYiYogis

See the above DoJo. Removing the factor seems to fix the issue, but I need the factor so that a user can type in 10 for 10% when the type is percentage but 10 for $10.00 when the type is currency.

Kendo tree list - kendo switch

Good afternoon, excuse my English is bad,

I have a kendo treelist in which there is a boolean column with a kendo switch.
The problem is visual when interacting with my tree list the switch is painted several times as shown in the image:
 
this is the code i am using:

{
                    field: "IsModule", title: "@Mui.Is_Module",
                    //width: "70px",
                    editor: checkBoxEditor,
                    headerAttributes: { style: "text-align:center" },
                    attributes: { class: "text-center" },
                    template: "<input class='checkBoxEditor' #if (IsModule) { # checked='checked' # } # type='checkbox' disabled />"
                },

If anyone can give me an idea of what I'm doing wrong, I'd be very grateful.

 dataSource: dataSource,
            excelExport: exportExcel,
            columnMenu: true,
            editable: "inline",
            cancel: function (e) {
                var grid = this;
                var rowUid = e.container.data("uid");
                setTimeout(function () {
                    grid.element.find("tr[data-uid='" + rowUid + "'] .checkBoxEditor").kendoSwitch({
                        messages: {
                            checked: "@Mui.Yes",
                            unchecked: "@Mui.No"
                        }
                    });
                });
            },
            dataBound: function () {
                this.tbody.find(".checkBoxEditor").kendoSwitch({
                    messages: {
                        checked: "@Mui.Yes",
                        unchecked: "@Mui.No"
                    }
                });
            },

function checkBoxEditor(container, options) {
    $('<input type="checkbox" name="' + options.field + '"/>')
        .appendTo(container)
        .kendoSwitch({
            messages: {
                checked: "@Mui.Yes",
                unchecked: "@Mui.No"
            }
        });
}

Data in kendogrid only shown after refreshing the grid manually, for some users

I have a strange problem, that only happens to some users.

The data is not shown for some users, although there is data. It's a really complexed application, so I hope I can give enough information.

function getWorkListItems() {

        setFieldValues();
        options = localStorage["grid-options" + viewStatesFilter];
        var gridSettings = {
            selectable: "multiple row",

        searchGrid.setDataSource(ds);
        searchGrid.dataSource.read();
       
        searchGrid.thead.find("[data-field=IsSelected]>.k-header-column-menu").remove();
        searchGrid.thead.find("[data-field=ID]>.k-header-column-menu").remove();
        if (options) {
            searchGrid.setOptions(JSON.parse(options));
        }
    }

At first Id didn't have the line

searchGrid.dataSource.read();

I added this, because sometimes the read function of the grid is not fired (for users who get the data this was working)

When I added that line the read function was fired and the data was collected (through the webapi). I can see that because result.Items countains the items.

I also added the line

searchGrid.refresh();

after

options.success(result.Items || []);

because It is working when I click the refresh button, but that also didn't solve my problem

But nevertheless, the data is not shown in the grid, only when I manually click the refresh button of the grid (then the read function fires again).

It is really strange why it works for some users and for other users it isn't working.

FYI this is build in a SharePoint application,

[Solved] Possible bug with column drag and drop when grid and gantt are in the same page

Hi,

I had to add the grid to part of my gantt page in the app and as soon as I added the grid, gantt drag and drop of columns started to fail.

On column drop lib fails with the following error:

Uncaught TypeError: Cannot read properties of undefined (reading 'lockable')
at init._allowDragOverContainers (kendo.all.js:311085:87)
at init._dropTargetAllowed (kendo.all.js:311085:87)
at init.drop (kendo.all.js:311085:87)
at init.trigger (kendo.all.js:311085:87)
at init._trigger (kendo.all.js:311085:87)
at init._drop (kendo.all.js:311085:87)
at kendo.all.js:311085:87
at init._withDropTarget (kendo.all.js:311085:87)
at init._end (kendo.all.js:311085:87)
at init.trigger (kendo.all.js:311085:87)

Problem is reproducible in the following Dojo

To reproduce issue, just try to change the order of the columns in the gantt widget.

Result: Widget breaks on drop and any drag or drop is not possible. Browser console shows error described above.

Expected result: Columns reordered

Tested with Chrome and Firefox.

If there is anything else I can do to help, please let me know.
