I am currently working on a piece where the user can Import an Excel Sheet, Modify and Validate it then Upload it to the backend service.

I have used an Upload Component to load the file into the spreadsheet and Upload when prompted by the user and this is working fine, but any modifications in the Spreadsheet Component will not be sent

I was wondering if its possible to upload the modified spreadsheet to a backend service.

You can only seem to Export it back out to a local file.

I have also tried the ProxyURL which could be a possible solution, but it navigates away from the current page and didn't seem to trigger the interceptor to add our auth headers

Is there a way to get the data behind the spreadsheet component or convert it to a base64 string, Blob or File?

Hi, 

I have few questions regarding kendo grid, i have implemented kendo grid for three nested levels, in every level it has checkboxes, i want to do if i select the parent level checkbox, it should  expand its child and all child checkboxes should also selected, is it possible in kendo-grid??
if so do you have any demo link?

i have attached the image for you understanding, but in that it has only one level, in my case i have two nested levels

Thank you

I'm implementing a search form using an ngbDropdown and the form contains a kendo-dropdownlist (to select what object type they want to search)

Unfortunately, when I select an option from the dropdown list, the menu closes. "autoClose" set to "false" works, but gives unwanted behaviour (in that the form itself almost never goes away). Worse, "autoClose" set to "outside" makes no difference.

Is there something I'm doing wrong?

Just to give an idea of what I'm doing, this is the beginning of the code (using Kendo 17.3.12):

<div ngbDropdown [autoClose]="'outside'" #searchMenu="ngbDropdown">
  <div id="searchMenuInner" ngbDropdownToggle>
    <span class="fa-solid fa-magnifying-glass"></span>
  </div>
  <div ngbDropdownMenu aria-labelledby="searchMenuInner">
    <div ngbDropdownItem>
      <div class="menu-header">Search</div>
      <div class="menu-item">
        <kendo-dropdownlist #searchType [data]="searchableItems"

I got a kendo Popup and inside a kendoFilter + kendoGrid.

Everything works well except when I press enter key when positioned inside the text field of one fitler row. The popup just close... DO I have a way to intercept this enter keypress and do something else ?

Thanks

In one of the recent releases (not sure from which release), even if we remove role SpinButton using renderer2.removeAttribute, in the ngAfterViewInit life cycle hook, after the kendo numeric textBox is rendered, the role spinButton is not going away from Kendo Angular Numeric TextBox. Any settings we need to do if we do not want this role?

What i tried can be seen in the sample below https://stackblitz.com/edit/angular-vfzhozgv . This is for 18.2.0. But, may be already working fine in latest version

Hello,

We encountered a problem inside our app while using the kendo-treelist component.

As shown in the video attached, we use a template to edit the values in the tree, which is either kendo-dropdownlist or kendo-numerictextbox. At the press of the kendo-icon-wrapper, which contains that arrow SVG icon (for increasing/decreasing the value or selecting from the dropdown), the whole row will either collapse or expand depending on the current state that it has.

From debugging, we believe that because the same SVG icon has been used, it might trigger the collapsing/expanding.

After adding a kendo-icon-wrapper component inside that cell, we could observe the same behaviour when pressing next to the 'test' text.

We are looking for a solution to this problem.

Thank you in advance.

Hi,

We need advice on how to add "id" and "for" reference attributes to custom angular components and associated kendo labels.

We use custom controls, that implement the ControlValueAccessor interface. We would like to use them with associated kendo-labels.

There is a good documentation here:

https://www.telerik.com/kendo-angular-ui/components/labels/label/association#other-angular-components

However it is not sufficient for our case. We need to keep WCAG conformity (level AA), means, the Html label element and the Html input element should be connected by attributes for and id, e.g.:

<label for="someId">Input here</label>
<input id="someId">

With standard kendo label and kendo input controls, these reference attributes for the inner Html elements are added by some kendo magic.
This however does not work if the kendo input control is wrapped in a component.
The accessability testing tools (e.g. WAVE, AInspector) mark this as an error.

Can someone propose a solution, on how to get the proper attributes onto the Html elements, or does anyone know a good and usable workaround (final ressort would be to set aria-label to the inner input element ...).

I attach a codesandbox  link which extends the kendo documentation mentioned above, and a screenshot with WAVE test result for the code snippet.

Thank you in advance.

Hello,

I'm using the Kendo Angular Gantt chart, using flat binding since that's how the data is stored in my database.  A lot of the example code for editing tasks, dragging tasks, etc. rely on using the subtasks property on the Task to determine if the parent start/end dates or the completionRatio needs to be updated.

What is the best way to calculate the new start/end date or completionRatio when using flat binding?  I know that I could make a call to the database to calculate this, but would prefer to calculate this locally if possible.  Thanks!

public onDragEnd(e: TaskDragEvent, gantt: GanttComponent): void {
    const originalItem = { ...e.item.dataItem };
    const editedItem = {
      ...originalItem,
      start: e.start,
      end: e.end,
      completionRatio: e.completionRatio,
    };

    const taskFormGroup = this.createFormGroup(editedItem);
    if (!taskFormGroup.valid) {
      // You can notify the user that the edited item is invalid.
      return;
    }
    // Update the edited item
    Object.assign(e.item.dataItem, {
      start: e.start,
      end: e.end,
      completionRatio: e.completionRatio,
    });

    // Edit the ancestor items accordingly if necessary
    if (this.anyChanged(originalItem, editedItem)) {
      let currentItem = e.item.parent;

      while (currentItem) {
        const dataItem = currentItem.dataItem;
        const subtasks = dataItem.subtasks;

        dataItem.completionRatio =
          subtasks.reduce((acc, curr) => acc + curr.completionRatio, 0) /
          subtasks.length;
        dataItem.start = new Date(Math.min(...subtasks.map((t) => t.start)));
        dataItem.end = new Date(Math.max(...subtasks.map((t) => t.end)));

        currentItem = currentItem.parent;
      }
    }
    gantt.updateView();
  }
