CTL/ Shift multiselection with large data and columns

Hello,

I'm working on a project where we have about 100 columns and rows can exceed 1000 rows.

The users want to enable CTL and shift selection but it doesn't work and I have 2 behaviors:

1- If I click quickly and simultaneously CTL and Select row it's works.

2 - If I start holding the CTL button and try to select row nothing happen and it takes long time to be selected.

can you tell me what the problem is exactly and if there is a bypass for it

Best regards

selectedKeys is not working after update kendo packages

I've prepared kendo grid with multiselection and everything was fine until I updated kendo packages:

My Kendo Grid properties:
  <kendo-grid  
  [selectable]="selectableSettings"
  (selectedKeysChange)="keyChange($event)"
  kendoGridSelectBy="id"
  [selectedKeys]="mySelection"
  >
Before update everything was fine I mean, I had correct objects (ids) into mySelection array number property.
Defined property into component:
    mySelection: number[] = [];
Selectable settings:
        this.selectableSettings = {
          checkboxOnly: true,
          mode: "multiple"
        };
KeyChange method:
    keyChange(e){
        this.closeEditor();
        if(e.length > 0) {
            this.isSelectionDisabled = false;
        } else {
            this.isSelectionDisabled = true;
        }
        this.extractDataItems = [];
        this.extract();
    }
Extract method:
    extract() {
        this.mySelection.forEach(idx => {
            this._subs.add(
                this.timeBookings$.pipe(
                    map(items => items.find(item => item.id === idx)
                )).subscribe(r => {
                    if(this.mySelection.length > 0 && r) {
                        this.extractDataItems.push(r);
                    }
                })
            );
        });
    }
Important!
When I'm selecting some rows - mySelection is always empty.
I know that in keyChange(e) method I can do something like:
this.mySelection = e;
and everything will work as should but why it was working correctly before update and after not?
Parameter of:
keyChange(e) - parameter e has correct value all the time

Strange characters in different Kendo objects

We are noticing these characters "â€<" showing up intermittently after updating our kendo-angular dependencies to 15.5.0.
It's not an issue we are able to reproduce every day, and sometimes reloading will fix it, but it will appear at the beginning of kendo window headers, and options in kendo dropdowns. We have not changed anything about our code, nor are we using any special characters ourselves in these locations.

Our angular version is 17.3.12

Is this a known issue? What would the fix be?

Thanks.

multiselect with icon of choosing

Hi, I'm trying to create a multi-select item that will have the outside look & behavior of a simple dropdown-list, including using icon of my choosing for the down arrow.

But I'm having trouble locating the icon, I've tried using plain css and play with the positions of the items, but then the icon doesn't stick to the corner of the multi-select wrapper..

Would like some help, I feel like maybe I'm doing it all wrong.

Here is my code:

LoadMoreDirective for MultiSelectTree?

I am presently utilizing a MultiSelectTree to display an extensive hierarchical dataset. Despite employing load on demand, performance suffers notably when a single level contains numerous elements.

I have come across a solution tailored for the TreeView to address this concern, wherein a limit for elements per level can be set, accompanied by a "load more" button once the limit is reached.

Is there a way to adapt this solution for the MultiSelectTree? Alternatively, are there other remedies available for optimizing performance with the MultiSelectTree?

horizzontal scroll in kendo grid with multiselection drag enabled

Hello,

I have a kendo grid with many columns and virtualcolumns set to true. I would like to know how to have the horizzontal scroll working while selecting cells with drag enable in order to select cells that are outside of the portion of grid visible in the screen. I've noticed that if I set drag to false the scroll works but then I'm not able to select multiple cells with the mouse. Thanks
