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.

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.

 

 

 

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

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

3. Navigate to the next page.

4. Rows are misaligned.

Bug report

The Grid's pdf.repeatHeaders option does not display the column headers for each new page when exporting the Grid to PDF

2. Export the Grid

Current behavior

Expected/desired behavior

The column headers should be present for each PDF page

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.

Bug report

Grid throws error when partial update is executed and selection is persisted

Reproduction of the problem

1. Open the following dojo.
2. Select a row.
3. Place it into edit mode.
4. Make some changes and click on the Save command button.
5. Try to select another row.

Current behavior

The Grid throws an error when the partial update is executed and the selection is persisted.

Expected/desired behavior

The Grid should not throw an error when the partial update is executed and the selection is persisted.

Environment

• Kendo UI version: 2024.1.319
• Browser: [all]

Steps:

1. https://dojo.telerik.com/URaJeSEk
2. Click the "Change Price" button

Expected: kendoConsole logs the dataItem info in the top message
Actual: dataItem() doesn't find the model even though it exists in the Grid dataSource

In the Grid source code in the refresh function, _data is set to dataSource.view() if partialUpdate is true. For a grouped dataSource, view() will return the parents. This breaks the dataItem function since it relies on the flat array for retrieval.

It looks like this issue was introduced in version 2024.1.319 as it doesn't seem to affect 2024.1.130.

Bug report

When calling the exportSelectedToExcel method and passing true to it, so that the headers are also exported, a js exception related to the aggregates (count, sum, etc.) is thrown.

Reproduction of the problem

Dojo example: https://dojo.telerik.com/UkIloRag/3

1. Select a few cells and click the button above the Grid.

Current behavior

A js exception is thrown.

Expected/desired behavior

No js exception is thrown and the Grid is exported as expected.

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.

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
