We have a project where we need the infinite scroll, column sorting/filtering, and remote data enabled.  We are having some issues with sort and filter.  For quick reference, I used the grid demo and changed it to reflect our configuration.  The problem is the grid fires the read command twice when we have loaded more than one page of data. No issues when we have only loaded the first page.

https://dojo.telerik.com/UDoREFID

To reproduce:

1.  Open Chrome

2.  Load the page

3. Hit run

4. Open Developer Tool

5. Switch to the Network tab and filter by XHR only  

7. Click ProductName to sort. There is only one AJAX call.

8. Scroll to the bottom so it loads the next page. It made two AJAX calls

Bug report

When the horizontal scroll of the grid is shown and is configured for RTL, the resize handle is mispositioned. 

Reproduction of the problem

1. Make the grid scrollable and set explicit widths to all columns.

2. Make the grid RTL.

3. Introduce multi-column headers.

4. Notice that the columns cannot be resized due to the disposition of the handler.

5. Dojo for replication:

https://dojo.telerik.com/IZInOVUd

6. Notice that whenever the horizontal scroll is not present, the resize handle is positioned correctly.

Bug report

The Pager breaks if you use the setOptions method to alter its options.

Regression introduced with 2023.2.829

Reproduction of the problem

1. Open the Pager Grid demo - https://demos.telerik.com/kendo-ui/grid/pager-functionality
2. Check either of the checkboxes to change the Pager options

Current behavior

After checking a checkbox, only the arrows remain from the Pager.

Expected/desired behavior

The Pager should remain whole when you alter its options.

Issue that I have can be observed on any grid with checkbox selection and filtering enabled at the same time (I edit this demo https://demos.telerik.com/kendo-ui/grid/checkbox-selection by adding filtering an already I can see my problem).

I have a grid with 10 records with checkbox selection, filtering and "persistSelection" option enabled. I select a single record with a checkbox. I use filtering and only 5 records remain visible, selected record is not visible (didn't match the filter). When I clear the filter my selected record remains checked. If I do the same but filtering causes all records to disappear then after clearing the filter my selected record is no longer checked. So we can see that selection persistence works differently depending on results of filtering. That is confusing and looks like a bug.

There is an annoying bug with the latest version of Kendo UI for jQuery (2020.2.617). In grids with commands, there is a problem in column menu. When we try to show/hide a column, another column is hidden. Here is a sample that reproduces the problem : https://dojo.telerik.com/@kakone/awUhelIZ. In this sample, try to hide the "Ship Country" column, you will see the problem.

### Bug report

When the grid uses GroupPaging, Locked columns and one group spans over two pages, the header rows on the second page are misaligned.

### Reproduction of the problem

1. Create a Grid with GroupPaging and Locked columns.

2. Expand a group that should span over the next page.

3. Navigate to the next page.

4. Rows are misaligned.

### Bug report

The column menu of the Kendo UI Grid widget with componentType set to 'modern' has missing translations in the default filter menu.

### Reproduction of the problem

1. Create a filterable grid and enable the column menu with componentType 'modern';

2. Include the localization script for "fr-CA" in the document from the CDN;

3. Open the column menu and expand the filter menu of a specified column. The logic operators "And" and "Or" are not translated.

A Dojo sample for reproduction: https://dojo.telerik.com/UYIrABUw

### Expected/desired behavior

When the column menu type is set to "modern", the operators of the filter menu should be translated as in the "classic' column menu.

* **Kendo UI version: 2021.3.914

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.

Sample Dojo:

https://dojo.telerik.com/AcipENOt

Kendo UI version: 2019.1.220

It is possible to add new inline rows to grid even though they are not valid. 

Steps to replicate in attached dojo:

https://dojo.telerik.com/oJEMAPoJ

1. Apply any search in search panel

2. Click Add New Record (one or mutiple times)

3. Click SaveChanges

4. Delete search phrase

The result is that new rows have been added with empy ProductName column, which supposed to be required.

 

 

 

Hi Guys,

I have just tripped over a problem in the 2020 R1 release whereby the sort indicator is not being shown when autoBind is set to false.

To illustrate the problem run the following dojo

    https://dojo.telerik.com/eMELiMut

which will show a sort indicator on the 'Ship Country' column.

Now if you uncomment 'autoBind:true' and 'dataSource.read();' and re-run you will see that although the data is being sorted correctly the 'Ship Country' column is missing the indicator.

Regards
Alan

Hi,

I updated my project to Kendo UI for jQuery 2020.3.1021 but then all Grids stopped working on mobile or tablet devices. When downgrading to 2020.3.930 grids works fine. Also tried it with 2020.3.1028 but same issue.

I have tested it on iPad, iPad Pro, Samsung S10. Same issue with Chrome/Edge Chromium and emulate a mobile/tablet device.

In the browser console you can see the javascript error: "Cannot read property 'rows' of null".

Reproduction of the problem:

1. Go to https://demos.telerik.com/kendo-ui/grid/index
2. Hit F12 top open the Developer toolbar
3. Click on "Toogle device toolbar" (CTRL + SHIFT + M)
4. Choose any device, ex: iPad, iPhone
5. Reload page to make the changes take effect
6. Click on "Run live demo"
7. Grid not loading!!
8. Console is showing a JavaScript error: "Cannot read property 'rows' of null"

1, Open the Dojo example
2. Scroll to the bottom
3. Sort the Grid

Only the last 3 items are displayed. (screencast)

Note: The issue does not occur every time.

We have few of dynamically created grid controls. I like to change the grid header style for all of them. I found this solution on the forum however there is an issue with this. If I override ".k-grid-header th.k-header" the change effects column filter popup content as well. See this example on dojo: https://dojo.telerik.com/@ssharifi/AvayONaQ all text and drop down texts are also effected.

I just need to override the title text. What style can I set so the title text is bold but not the filter options?

Thanks,

Shawn
