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.

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.

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.

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

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

  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!!

Hello,

 

we have the following problem:

In the dojo https://dojo.telerik.com/uJUGEQuh clicking on a row from the skleton loader in the grid causes an error. It seems like you want to access the "id" field from the datasrouce model which doesn't exist in the loading animation.

model:
{
	id: "Id",
	fields: 
	{
		ProductName: { type: "string" },
		Id: { type: "number" }
	}
}

 

If you rename the "id" field to for exmaple "XXXX" the error message changes

from:

Uncaught TypeError: Cannot read properties of undefined (reading 'Id')

to:

Uncaught TypeError: Cannot read properties of undefined (reading 'XXXX')

 

We attached a gif of the problem and the code snipped of the dojo. The browser is Chrome Version 109.0.5414.120 (Official Build) (64-Bit)

 

Greetings

Ingo E.
