Bug report

When the Grid is configured with a ColumnMenu and the Filterable option is enabled, and there is a date column, the filter operates correctly upon initial application. However, when the filter is reopened, the second DatePicker is automatically populated with the value from the first DatePicker. The issue occurs since version 2025.1.211.

I need to get the output of a grid saving to pdf without sending the resulting PDF directly to the user. For example, a PDF export option "localexport: true" which would return the data to code instead of directly to the client.

Currently, the file data can be retrieved using the private _drawPDF method:

        var grid = $("#grid").data("kendoGrid");
        var progress = new $.Deferred();

        grid
          ._drawPDF(progress)
          .then((root) => {
            return kendo.drawing.exportPDF(root, grid.options.pdf);
          })
          .done((data) => {
            console.log(data);
          });

Example: https://dojo.telerik.com/rjEORuHy.

However, the approach does not work well in all scenarios for example, when there are multiple pages - https://dojo.telerik.com/iiifASYZ/2 

Thus, I would like to have a built -in method that will be suitable for all scenarios to generate and retreive the file data, without sending the file to the client.

Hi Team,

I would like to request a way to turn off or toggle double tap editing for mobile Kendo UI Grids with incell editing introduced in R3 2023. 

Thank you!

Hi Team,

I would like to request to add Excel exporting for the Grid to include Selected rows, including checkbox selection.

Thank you!

Hi Team,

I have a Kendo UI Grid where there are a lot of columns.  But, due to the recent changes in version 2024 Q4, the columnMenu does not contain a scroller.  

Thank you!

Bug report

When the user adds a group in the Grid and try to add a second group immediately, while the first grouping is still loading, then an error is thron in the console.

Reproduction of the problem

1. Open the dojo - https://dojo.telerik.com/CvYRPILM
2. Group by 'Freight' and immediately try to group by another field. Before the grid data source reloads from the first grouping, take another column to be grouped and select it without releasing it in the grouping space.
3. Once the first group has been loaded, release the second group

Note: you can try setting the n browser Network throttling to Slow 4G to easily reproduce the issue

Current behavior

Error: kendo.all.js:60347 Uncaught TypeError: Cannot read properties of undefined (reading 'left') is thrown and the Grid freezes

Expected/desired behavior

There should be no error in the console and the Grid should not freeze

The issue is a regression starting with 2023.1.314

Reproduction of the problem

2. Inspect the last column

Current behavior

k-sorted class is added to the last col of the colgroup. The issue is triggered by this line of code in the Kendo ColumnSorter

table.find("col:not(.k-group-col):not(.k-hierarchy-col)").eq(headerIndex).toggleClass("k-sorted", dir !== undefined$1);

Expected/desired behavior

The class should not be added if the column that is sorted is hidden.

I have a Kendo Grid that follows the Set Multi-Checkbox Filtering to Use contains instead of equalTo.

- https://docs.telerik.com/kendo-ui/knowledge-base/grid-how-to-change-multi-checkbox-filter-to-contains 

This works, I am able to filter the Grid on contains condition; but after filtering and opening the column filter again, the checkbox is not selected and shows unchecked. 

I managed to fix the issue and persist the checkbox selection using the following approach:

columnMenuOpen: function(e){
            if(e.sender.dataSource.filter()){
              e.sender.dataSource.filter().filters.forEach(function(f){

                if(f.field == "OrderID" || f.field == 'ShipCountry') {
                  var checkbox = e.container.find("input[value='"+f.value+"']");
                  if(checkbox[0] && !checkbox[0].checked){
                    e.container.find("input[value='"+f.value+"']").click()  
                  }          
                }else if(f.filters[0].field == "OrderID" || f.filters[0].field == 'ShipCountry'){
                  var current = f.filters;

                  current.forEach(function(filter){
                    var checkbox2 = e.container.find("input[value='"+filter.value+"']");

                    if(checkbox2.length > 0 && !checkbox2[0].checked){
                      e.container.find("input[value='"+filter.value+"']").click()  
                    } 
                  })
                }
              })
            }
          },

Demonstrated also in the Dojo linked here - https://dojo.telerik.com/MBDcImcj.

I would like to see the functionality built-in, so I don`t need to customize the Grid behavior in its columnMenuOpen/filterMenuopen event hanldlers
