I have a treelist with scrolling and locked columns. Unfortunately, when the screen is wide enough to display all of the columns, the grid doesn't expand to fit the headers as seen in the included screenshot. Also, when I do expand the columns past the max height of the grid, I do not get a scrollbar and the ones below get cut off. Can you help with this? This same table works in a grid (minus the expansion piece, hence converting to a treelist). It does appear there is a scrollbar but it is outside of the table's viewable area.
Here is a dojo: https://dojo.telerik.com/@dojolee/oraQASED
Attached is an image of what I am seeing on my site.
Here is my code:
$("#tileTable").kendoTreeList({
            dataSource: {
                data: treeDataSource,
                schema: {
                    model: {
                        id: "hierarchyId",
                        parentId: "parentHierarchyId",
                        fields: {
                            parentHierarchyId: {
                                type: "string",
                            }
                        }
                    }
                }
            },
            sortable: false,
            columns: columns,
        }).data("kendoTreeList");I have a kendo treelist and need to include a column menu to show or hide columns. My column headers have classes applied to them on initialization via the headerAttributes option. After hiding a column, the remaining columns' headers lose their classes. This is duplicated in the attached dojo. Notice last name is in blue. When you hide first name using the 3 dot menu, Last Name turns black. I have tried the same thing with a kendoGrid and it works as expected. Something is off with the TreeList. How do I fix this? Note that while my example here uses text color, using a template won't solve my real issue as I need the class applied to the header cell itself so I can center the content and other stuff.

In troubleshooting, I noticed that grid.columns is not returning headerAttributes.class for the treelist when calling $("#myGrid).data("kendoTreeList").columns for the tree list but it is when calling $("myGrid).data("kendoGrid").columns for the grid. I'm attaching images from my own project of the two returns (Note that they are from different instances which is why the other data is not the same in the two screenshots nor do they go with the dojo.)
Hello Team,
I have run the FastPass on the kendo control present at the below URL and found the a11y issues.

Please check the below images
On fixing one of the issues(adding aria-label attr) shown in the above image, new a11y issues are coming as shown in the below image.
On fixing the above one as well, new a11y issues are coming,
Please let me know how can we fix this problem?
Thanks & Regards

My dataSource change handler is getting an event with with e.action set to itemLoaded, which is not one of the defined values in the API documentation.
I am wondering if this is a valid event action that I can target and the documentation is not correct, or if this is something else like a bug.
Here is a dojo. If you run it and expand the item, in the browser console you will see a couple events, the last of which is the itemLoaded event.
Good day,
When I'm dragging a row, if I hover over the insert indicator on the left of the grid it causes the tooltip (and sometimes the whole row) to flicker/flash, Ive noticed this issue exists on the tutorial page too, is there a work around for this?
The tutorial I used: https://demos.telerik.com/kendo-ui/grid/drag-drop
Kind regards

Hello, I'm trying to prevent chat posting, I mean when user click send button (or type keybord enter) I want in some cases to prevent the post of the message.
Something like this is not working (the message is posted in chat)
$("#chat").kendoChat({
    post: function(e) {
        e.preventDefault();       
    }
});
Is that a bug? Or there is a different approach to accomplish this task?
Thanks,
Mattia
Hi,
i have a question regarding the DataSource.
I am using the code below. I don't have it in a separate file but in the <script> tag of the HTML. It's not the entire code either, that would probably be an unnecessary amount here. My problem concerns the valueOrderFinished. Inside the DataSource in the schema, the value is set. That works well, because when I set the innerhtml of #outputtest, the right value is displayed. But when I try to access it outside, in my document ready function, I always get that valueOrderFinihed is undefined.var showProfile = 0; var valueOrderFinished; [...] var dataSourceOrderFinished = new kendo.data.DataSource({ transport: { read: { url: "Services/OrderServices.asmx/GetCountOrderFinished", contentType: 'application/json; charset=utf-8', type: "POST" }, parameterMap: function (options) { return JSON.stringify({ parameter: options }); } }, schema: { data: function (result) { console.log(result.d.Count); document.getElementById("outputtest").innerHTML = result.d.Count; valueOrderFinished = result.d.Count; }, total: function (result) { return result.d.Count; } } } ); /* */ /* */ /* ++++ Funktionen ++++ */ $(document).ready(function () { console.log("dokument ready"); hideProfileElements(); console.log("Profilelemente versteckt"); valueOrderFinished = dataSourceOrderFinished.read(); console.log("datasource gelesen"); console.log(valueOrderFinished); createCharts(); }); [...]
