I have a simple react view with a form that has two Kendo MultiSelect dropdowns ^v5.9.0. One with category and the othe subcategory. 

CategoryDS: [{categoryId: 1, name: "Category-A"}, {categoryId: 2, name: "Category-B"}, {categoryId: 3, name: "Category-C"}], SubCategoryDS: [{SubCatId: 101, name: "CatA-SubCat1"}, {SubCatId: 102, name: "CatA-SubCat2"}, {SubCatId: 103, name: "CatB-SubCat1"}, {SubCatId: 104, name: "CatB-SubCat2"}, {SubCatId: 105, name: "CatC-SubCat1"}]

<MultiSelect
        data={subCategoryDS}
        value={subCategories}
        onChange={handleChange}
        style={{
          width: "300px",
        }}
        placeholder="Please select ..."
      />

In a scenario when selected category: Category-A, Category-B and in sub category MultiSelect: CatA-SubCat1, CatB-SubCat1, CatB-SubCat2. When we decide to remove Category-A from category MultiSelect we would like subcategory MultiSelect selection to also remove CatA-SubCat1 from selection to relect our action. How do we handle this to show our intention? For context sake we have onchange method of category MultiSelect to handle the assigning of our subcategory multiselct data like so: 

let subcategoryDropdownList = document.getElementById(`subcategory-multi-dropdown`).parentElement.parentElement as unknown as MultiSelect;
  subcategoryDropdownList.data = subCategories; //trying this according to docs
  subcategoryDropdownList.value = subCategories; //trying this hailmary and pray

However we're getting the object alright but assigning anything to it like so doesn't work. Neither does letting React work with data and state to follow convention like : 

const [subCategories, setSubCategories] = React.useState([]);
setSubCategories((pv) => ({
  ...pv,
  { options }
  }));

It would seems as if once the MultiSelect is touched and selection set it wouldn't respond to changes and it doesn't have MultiSelect.Refresh() void method like its jQuery equivalent. if anyone could please help would make my day as I'm loosing hair and going grey trying to solve this tough one. Many Thanks in advance

Hi,

How to expand all nodes by default in treeview in react?

Can anyone give example how to achieve this?

Hi,

I have questions as I'm trying to format the value of the charts and its labels.

I used this but not working on my end. Can you check what am I missing on this.

1.) Convert to Dollar amount and round to millions also to lessen space and show properly.

<ChartSeries> {series.map((item, idx) => <ChartSeriesItem key={idx} type="column" tooltip={{visible: true}} data={item.data} name={item.name} format="c0"> <ChartSeriesLabels format="c0"/> </ChartSeriesItem> )} </ChartSeries>

2. I'm trying to round it to the Millions and used FormatLongNumber function where should I call/put this?

    function FormatLongNumber(value) {
            if (value == 0) {
                return 0;
            }
            else {
                // for testing
                //value = Math.floor(Math.random()*1001);

                // hundreds
                if (value <= 999) {
                    return value;
                }
                // thousands
                else if (value >= 1000 && value <= 999999) {
                    return (value / 1000) + 'K';
                }
                // millions
                else if (value >= 1000000 && value <= 999999999) {
                    return (value / 1000000) + 'M';
                }
                // billions
                else if (value >= 1000000000 && value <= 999999999999) {
                    return (value / 1000000000) + 'B';
                }
                else
                    return value;
            }
    }

3.) How to convert this to MMM/YYYY format?

here is the data I'm passing

[
    "1/24/2022",
    "2/8/2022",
    "2/21/2022",
    "4/13/2022",
    "5/5/2022",
    "5/17/2022",
    "6/8/2022",
    "6/14/2022",
    "6/22/2022",
    "6/24/2022",
    "6/27/2022",
    "7/27/2022",
    "8/1/2022",
    "8/12/2022",
    "9/28/2022",
    "9/30/2022",
    "10/12/2022",
    "12/13/2022",
    "12/16/2022",
    "12/19/2022",
    "12/30/2022",
    "1/24/2023",
    "1/26/2023",
    "1/27/2023"
]

I'm attaching my html file for full reference. Thank you in advance!

Hi!

We are trying to customize the scheduler form editor, but the field is not showing up. Any ideas why? Screenshots of the SchedulerForm's editor and what we see in the UI below:

What we see: (text area input doesn't show up):
*note that we have tried other field types (e.g. dropdown and datepicker) with similar results

Thank you!

https://stackblitz.com/edit/react-ucebku-vmycow?file=app%2Fmain.jsx from the comments in this thread: https://www.telerik.com/forums/column-menu-doesn-t-work-in-custom-headers

The actual column menu for the "test" column (utilizing a custom headerCell) doesn't work.

Additionally, and this may be because I'm behind by a few versions, React doesn't like the `props={....props}` on `line 23`. However, despite it not working on my end locally, the demo is working with this but still not working overall.

Similar to the Grid's `expanded` prop, do the TreeList GridColumnMenu components have the expanded feature? It saves my users one extra click, so it's a favorite! I was unable to make it work by doing this:

`<ColumnMenuTextColumn expanded={true}/>`

Similar to the Grid's GridColumnMenuFilter.active() method, is there either a method or an example for the TreeList to accomplish styling the ColumnMenu icon / header cell? I think I could build my own simple check for this, but wanted to see if there's a utility function already created.

Thank you!

Hi,

I am using the React Data Grid component and have a grid column with a custom cell renderer. I want to be able to filter on this column using the GridColumnMenuCheckboxFilter. However, the filter only shows an option of 'undefined' and not the values rendered by the custom cell component (see image below). The rendered values are not coming from a direct property of the grid data object, so I was wondering if there is a possibility to define a valueGetter that outputs the actual rendered value, which can then be picked up by the filter component?

Thank you
