Hi, 

Here is the dojo to reproduce. In this dojo I've created imitation of data, that coming from server in our case. The main idea is to have a grid with lazy loading - it has 10 groups (page 1) and after scrolling down it loads 10 more groups (page 2) and etc.

 

Issue 1. 

After scrolling down, data from the last group is updated with some data, that is not belongs to it. Please see 'Issue1.png' attached.

Issue 2.

Groups from the first page are duplicated after scrolling down. For example, there is a group named 'C3'. After scrolling down, it is duplicated once again. Please see 'Issue2.png' attached. New groups are placed after these duplications. By the way, as groups from the 1st page are duplicated, there is more than 20 groups is shown, but the counted at the bottom of the grid says that '20 of 137' elements are show.

 

So it would be great, if you could fix that. Or even provide temporary fix for us.

Thank you!

the Kendo grid does't accept cell value changes when using android mobile phone with the Chrome browser. You can test it on the telerik demo https:demos.telerik.com/aspnet-mvc/grid/editing.

for example change the value of the Unit Price and go to the other cell. you will see that the value will become the original value.

just by touching some where outside the border of the grid the value will change.

Following example @ https://docs.telerik.com/kendo-ui/knowledge-base/grid-sort-displayed-columns-menu-items sorts a column menu. When hide column is then clicked, the wrong column is hidden.

This can be seen in your own dojo example linked in the above doc and @ https://dojo.telerik.com/UWuxOseV . Hiding column Ship Name hides Ship Address instead.

This seems to have been introduced in 2019 R2 SP1 version.

When clicking on CheckBox to select a line, the widget check other checkbox (on other column of the same line) inserted from column template.

I suppose that the selector that the system use is too large.

 

For information, i created a template for boolean column based on how kendo generate checkbox structure (just de be coherent)

 

See the code extracted from https://dojo.telerik.com/EqiPIkiV

 

 var checkBoxtemplate = function(boolValue){
   	var checkedStr = '';
    if (boolValue) {
    	checkedStr = 'checked="checked"';
    }

        
    return '<input class="k-checkbox" data-role="checkbox" ' + checkedStr + ' type="checkbox"><label class="k-checkbox-label k-no-text smi-checkbox-fordisplay"></label>';
 };
  
$("#grid").kendoGrid({
  columns: [
    {
      selectable: true, 
      width: '30px'
    },
    { field: "name" },
    { field: "age" },
    { field: "administator", 
      template: function (dataItem) { 
        return checkBoxtemplate(dataItem.administator); 
      }  
    }
  ],
  dataSource: [
    { name: "Jane Doe", age: 30, administator: false },
    { name: "John Doe", age: 33, administator: false },
    { name: "BigBoss Doe", age: 70, administator: true }
  ],
  selectable: true
});

When there is not enough space for the filter menu to be opened downwards, it should be opened on top. However, the first time it is opened, it is positioned below the filter button. 

Experienced behavior: 

Filter menu is mispositioned when first opened. With consequent openings, the menu is positioned as expected.

Expected behavior: 

The calculation for the positioning should be done even with the first initialization.

A sample Dojo for the reproduction of the issue:

https://dojo.telerik.com/iRaDakEs

First initialization:

Second opening:

Whether you try to resize a "grouping column" (a column without an associated field) or a "data column" (the lowest level column - one with a data-index), resizeColumn does not work. The grid gets messed up. Sometimes the wrong column gets resized, sometimes columns just disappear.

After the kendoGrid is created, the headerAttributes field (of every column) has a id value (generated by Kendo) of some random GUID - but this GUID is nowhere to be found in the entire HTML.

So, there is no way to link a Kendo column object to an HTML (th) element.

  2. Enter in Edit mode via the Edit button
  3. Navigate to the Update button via keyboard

Current behavior

Detail Template is toggled on Enter.

Expected/desired behavior

Release 2019.R2.SP.Next

The issue is reproducible when the grid consists only from Multi-header columns, the setDataSource() method has been used and one of the columns is initially hidden.

After setting the new data source, the last header gets hidden. The "display: none;" style has been applied to the "th" HTML element.

Steps to reproduce:

1. Create a grid with multi-header columns only.

2. Hide one column initially.

3. Set a new data source via the setDataSource() method.

4. The last column gets hidden.

Hello guys,

I am stuck with this problem for some time now. Everything works well with mouse, I can drag and drop column into grouping header normally. But on touchscreens I can't drag it. I am interested if anyone has had this issue?

Hi Team,

Kendo grid does not allow all columns to be hidden from column menu as it disables the check box for last column in column menu.

But if we set hidden = true and menu = false properties for column, grid hides that column from grid and column menu, but enables the checkbox to hide all columns from grid leaving it empty. After which we can't get back the columns in grid which isn't valid.

Grid should always allow at least one column to be included in grid/menu.

Please find attached screenshot and below sample link.

https://dojo.telerik.com/EHOgaJUK/2

Thanks,

Jyotika

Hi,

Bring up an RTL kendo Grid which has resizable true and filter mode is "row".

then try to resize the grid from filter-row of grid. we will see an internal js error.

 

you can copy and paste this code in a dojo sample and resize grid from the point is shown in the attached picture.

    <div class="k-rtl"><div id="grid"></div></div>
    <script>
        $("#grid").kendoGrid({
          columns: [
              { field: "name" },
              { field: "age" }
          ],
          filterable: {
              mode: "menu, row"
          },
          resizable: true,
          dataSource: {
           data: [
            { id: 1, name: "Jane Doe", age: 30 },
            { id: 2, name: "John Doe", age: 33 }
           ],
           schema:{
            model: {
             id: "id",
             fields: {
               age: { type: "number"}
             }
            }
           }
          }

Hello Support Team,

with jQuery 3.3.1 the resizable option set to true is not working with the configuration in the example below. When removing other options like "toolbar" or "scrollable" it works. :D 

See the following example: https://dojo.telerik.com/IkigawaX

With jQuery 1.x everything works fine.

Regards

Alexander

The autofix column feature does not work properly if you enable sorting on the grid. You can see the issue if you open the Dojo for the following demo: https://docs.telerik.com/kendo-ui/knowledge-base/grid-autofit-all-columns-width

If you sort e.g. by column "Ship Country" and sort ascending you will see the name of the column ending with "..." but not the icon for the sort direction. If you press the column again and sort descending than everything works as expected - the column width increases and the icon is show.

I tested the problem in multiple browsers, but the main browser I have to support will be the IE.

Christian

The following event-handler does not work when run in a mobile environment (iPad). Otherwise it works as expected:

Result: all columns a set to their minimum width.

 

    var grid = $("#grid").kendoGrid({

// ...       
],

        columnShow: function (event) {

            console.time('autoFitColumn');
            for (var i = 0; i < this.columns.length; i++) {

                var col = this.columns[i];
                             this.autoFitColumn(i);
