I have an object in my grid schema and column definition. Upon load i set the grouping on on the Name field of my Category object. I also hide these columns since the grid doesnt appear to know to not show them when I do this. 

Category: {  defaultValue: {Id:null, Name:null}},


{field:"Category", title:"Category",editor: CategoryDropDownTreeEditor, template : "#= Category.Name #", hideOnGroup: true},



var g = $("#assetGrid").data("kendoGrid");
                g.dataSource.group( [{ field: "AssetId" },
                     { field: "Category.Name" } ]);
                g.hideColumn("AssetId");
                g.hideColumn("Category");

Here is my editor template if needed:

function CategoryDropDownTreeEditor(container, options){

            $('<input required name="' + options.field + '"/>')
            .appendTo(container)
            .kendoDropDownTree({ 
                dataTextField: "Name",
                dataValueField: "Id",
                autoBind:false,
                filter: "contains",
                height: 400,
                width:750,
                select: function(e) {
                    if(e.sender.dataItem(e.node).hasChildren){
                        e.preventDefault();
                    }
                }
                
            }); 

            $.ajax({
                    url: "/Categories" ,
                    dataType: "json", 
                    type:"GET",
                    contentType: "application/json",
                    data:{
                        MainCategoryId:options.model.MainCategoryId
                    },
                    success: function(result) {
                        $('input[name="Category"]').getKendoDropDownTree().dataSource.data(processTable(result, "id", "parent", 0));
                       
                      
                    },
                    error: function(result) {

                        console.log("fail");
                    }

                });

         }               

When I hit edit on my record the value disappears on the grouping header:

and if i hit cancel the value doesnt come back:

Hello, I am currently using the kendo grid to display all my data, I am wanting to be able to update one of the columns data by pressing the column and then a dropdown appear and i want to be able to change it. Is this possible? 

Kind Regards

I am looking for a help where I need to recreate the options for column filter values when the data on left hand side filter changes?

I have a drop down list country on left hand side and when ever user select the country the column(region), filter (custom filter, based on column on the grid) all the checkboxes for the custom filter should reflect the region as per the country selected.

Hi,

I build an Kendo UI TreeList. However, when I implement inline editing, I realize that the API calling from the kendo ui treelist sometimes work and sometimes not. When it work is mostly after I open a developer browser tools. 

I have record the process in Telerik Fiddler Jam, but 1 question, is there a way I can share the link privately for your expertise to help to take a look on what is happening

Here is the image that I want to

Hi,

I have a grid with row selection enabled, scrolling enabled and 2 sticky rows on the right side - many other options besides but these are not relevant here.
Using the Sass themes with the latest patch, 2023.1.314, and selecting a master row, then scrolling the row horizontally so the row data slips under the sticky row cell, the data shows through the sicky row content.  It seems to be OK on the Alt rows though.
This does not happen on ALL themes and swatches, just some - the default-main theme is an example.

I have tried it on the version released prior - 2023.1.117 and this problem is not there.

My actual project allows the operator to change themes/swatches so this would be an issue and limit the themes I could make available.

Is this by design?

I do not really want to start modifying themes if I can help it, is there a simply work around so all themes could be used without this 'feature'?

Dojo example lifted directly from your demos here: https://dojo.telerik.com/upeVIwil and I have included an example in text form and screen shots.

Many Thanks

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. 

https://dojo.telerik.com/ALeLiZUV

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.

https://demos.telerik.com/kendo-ui/dropdowntree/checkboxes

https://demos.telerik.com/kendo-ui/dropdowntree/index

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
