Hello, this is really not a question, but it is actually a bug that I discovered and possibly fixed, so I would like this to be included in the documentation.

Hello, this is really not a question, but it is actually a bug that I discovered and possibly fixed, so I would like this to be included in the documentation. If you use the paging functionality of Kendo-react-grid component or even go to this page: https://www.telerik.com/kendo-react-ui/components/grid/paging/ and check the first example on the official docs page, you will notice that when you click on the dropdown and select "All" so that you can see all the possible records on the grid in that single page, you won't be able to. The grid will display "No records available". So I faced the same issue when implementing pagination on this project and as soon as I would click on "All" I won't be able to see any records. So I debugged this and found the problematic code.

const pageChange = (event) => {
    const targetEvent = event.syntheticEvent;
    const take =
      targetEvent.value === "All" ? products.length : event.page.take;
    if (targetEvent.value) {
      setPageSizeValue(targetEvent.value);
    }
    setPage({
      ...event.page,
      take,
    });
  };

Here in the second line, where const targetEvent has been initialised with event.syntheticEvent, I changed it to event.targetEvent and this started working for me. I am not sure if it will work for all the people out there or if it is even the best solution, so in the meantime I get an official update from kendo react team, I will call it as a "workaround". I am using Chrome in case it matters. I submitted this as a question because I didn't know how to submit this as a bug to the official kendo team. Hope it helps, thanks!

FooterCell doesn't work in DataGrid at all.

Hi. I faced a problem with rendering footerCell . It worked for me in version 3.18.0 but after update it doesn't work in versions 5.16.0 - 5.18.0.

Also I found out that it doesn't work in any your DataGrid examples if I addngi footerCell functionality.

FooterCell looks like :

footerCell={props => (<td className='k-table-td' colSpan={props.colSpan} style={props.style} role={'gridcell'}>Total: </td>)}

or

footerCell={() => <td>Total:</td>}

In my solution and in all your examples it crashes DataGrid rendering.

I attached screenshot from my solution, but the same bihavior if I adding this lines of code in any your example of DataGrid demo site.

Is it bug, or what am I doing wrong?

Apply styles on PDF with k-pdf-export and other classes

Hello Telerik team,

Hey, I am trying to apply styles on the exported PDFs but not globally to all tags.

Suppose I have some `p` elements that should have styles A and some other that should have styles B.

The following will not work.

.k-pdf-export .class-a p {

  border: 1px dashed rgb(194, 23, 23);

}

.k-pdf-export .class-b p {

  border: 1px dashed #aaa;

}

The selectors will not work. Relevant example:

https://stackblitz.com/edit/react-zhmi5y?file=app%2Fstyles.css

So my questions are:

1. Are the other classes removed?

2. How can I achieve what I need?

3. If this is not supported as of now are there any plans to consider supporting it?

Thanks!

How to remove hours within a day in Scheduler week view?

I want my scheduler (in week mode) to have as many rows as there are users (Y-axis) and then each day of the week would form a cell for each user where the events would be shown. Currently, I'm struggling to understand how to change all day and hours to just a day containing all events regardless of the hours.
I've attached a picture for a better understanding of my goal

How to have a stacked bar chart represent time?

I have a stacked bar chart that I want to use to emulate changes in activity. Say the chart spans 30 minutes. I want the stacks to show when each category changed activity and for how long. For example, Zone 4 Cell 10 might be active for 5 minutes, inactive for 10 minutes and then active again for 15 minutes. Zone 4 Cell 20 might have a very different activity timeline. All activities are known (eg "active", shown below as green). An example is shown below.

Is there a way to achieve this with the basic stack chart library available in Kendo React? If so, how should the data be structured to be able to achieve this?

How to enable users to smoothly select data points when the line chart data is close.

Hi,
I am using kendo React Line chart in my project. When the line-chart data is close, the points will overlap, and the tooltip also will affect the user's selection of data. Do you have any good suggestions to solve this situation?
What I am currently thinking of is to filter the data by clicking on the legend, so that I can select points.
