DropDownTree Height does not work in Vuetify v-dialog

We have a Vuejs and Vuetify application.

We are using the DropDownTree control to display a hierarchy. In some cases, the list can be very long and scrolls off the page.

I tried using the "Height" property. This works for the DropDownTree controls that are NOT in a v-dialog.

But one of our DropDownTree controls displays in a v-dialog. The "Height" property has no effect here.

How can I make the "Height" property work for the DropDownTree in a v-dialog?

Or how can I specify a height for the DropDownTree or add scroll bars when the DropDownTree appears in a v-dialog?

Screen reader support

A number of Kendo components could do with better support for screen readers, including:

Pagination (eg in a grid): page links should read something like "Go to page 1", not just "1".
Dialog's labelled by and close button less confusing - it currently reads the whole header row, several times in a row.
Upload / external drop target: Upload hints are running through without a gap.
Grid: the header is confusing noise, it reads out "table with zero rows and zero columns" (depending on grid scrolling settings)
Date / date range inputs: reads "day/month/year" but not the field label, it's very hard to navigate the date picker.

No doubt there are more than the above.

Effective screen reader accessibility is as much about what you skip as what you add. Where possible, audio prompts should be short and clear, and not produce excess noise.

Size of Kendo download

Plea for help: Our front end guy left, and I've inherited his work :( I like the JS stuff, but I'm no expert.

Our new app has about a 4 megabyte app.js download, even when minified. We've turned on gzip compression on the server, and that gets it down to a bit over a meg, but we had a $1000 bandwidth overage last month!

I've been tasked with seeing if we are including unused code.

So, my question: In the docs I see this:

// As an alternative, you could import only the scripts that are used by the utility:

// import '@progress/kendo-ui/js/kendo.data' // Imports only the DataSource script and its dependencies

import '@progress/kendo-theme-default/dist/all.css'

import { DataSource,

HierarchicalDataSource,

GanttDataSource,

GanttDependencyDataSource,

PivotDataSource,

SchedulerDataSource,

TreeListDataSource,

DataSourceInstaller } from '@progress/kendo-datasource-vue-wrapper'

Vue.use(DataSourceInstaller)

new Vue({

el: '#app',

components: {

DataSource,

HierarchicalDataSource,

GanttDataSource,

GanttDependencyDataSource,

PivotDataSource,

SchedulerDataSource,

TreeListDataSource,

DatasourceInstaller

}

})

I've got about six of these: layout, dateinputs, inputs, dropdowns, dialog, etc.

If I can identify which of the features I need from each I need from each "wrapper", can I cut this down? For instance, I'm sure we don't use gantt charts or pivots above.

Thanks,

Ed Greenberg

Native DropDownList issues

I have started using the new Vue Native DropDownList and found a few issues when it is used inside a popup (bootstrap-vue modal).

The dropdown list will not display. I can make it display by adding:

.k-animation-container {
z-index: 100000;
}

Now it displays but clicking out side the dropped down list will not close it.

Exportar un reporte a excel sin formato

Como puedo exportar un informe que realicé en telerik a excel, estoy ocupando la extensión xls, sin embargo me lo entrega pero con el formato del informe, y yo pretendo pasarlo sin formato solo que respete las filas y las columnas.

private string creaReporteHomecito(ReporteHome listModel)
{
//CREAMOS EL REPORTE
ReportHome home = new ReportHome();
home.table1.DataSource = listModel.Ppi;
home.table2.DataSource = listModel.IsrRS;
home.table3.DataSource = listModel.IsrRA;
home.table4.DataSource = listModel.IsrRSO;
home.table5.DataSource = listModel.IsrRH;
home.table6.DataSource = listModel.IsrRAR;
home.table7.DataSource = listModel.PdI;
home.table8.DataSource = listModel.IrE;
home.table9.DataSource = listModel.IrR;
home.table10.DataSource = listModel.IepsE;
home.table11.DataSource = listModel.IepsR;

//EXPORTAMOS EL EXCEL ReportProcessor reportProcessor
= new ReportProcessor();
Telerik.Reporting.InstanceReportSource instanciaReportSource = new Telerik.Reporting.InstanceReportSource();
instanciaReportSource.ReportDocument = inicio;
RenderingResult renderingResult = reportProcessor.RenderReport("CSV", instanceReportSource, null);

//EXPORTAMOS EL EXCEL A MEMORYSTREAM
MemoryStream ms = nuevo MemoryStream();
ms.Write(renderingResult.DocumentBytes, 0, renderingResult.DocumentBytes.Length);
ms.Flush();
System.Web.Mvc.FileContentResult resultado = nuevo System.Web.Mvc.FileContentResult(ms.GetBuffer(), renderingResult.MimeType);
result.FileDownloadName = "ReporteGeneral.CSV";

byte[] excelBytes = ReadToEnd(ms);
cadena excelBase = Convert.ToBase64String(excelBytes);

volver excelBase;

SASS Compile error when kendo scss files are imported in stylesheet

Hello,

I've an error regarding Kendo style when I import it into an SCSS file. Let's assume I want to customize Kendo theme, I have 4 scss files :

_tokens.scss which contains color palette definition
the kendo scss theme (kendo-theme-bootstrap in this case, but same issue with the default theme)
_overrides.scss which may contains overrides (typhography, margin/padding on some components, etc)
and a base.scss file containing basically the import of the 3 preceding files :

@import 'tokens';
@import '@progress/kendo-theme-bootstrap/dist/all';
@import 'overrides';

However, when I import my base.scss file into the Vue App (whether in the main.js or the App.vue), I've this error :

Plugin: vite:css
  File: /src/node_modules/@progress/kendo-theme-bootstrap/dist/all.scss:37542:173
  Error: expected ";".
        ╷

        │                                                                                                                                                                             ^
        ╵
    node_modules/@progress/kendo-theme-bootstrap/dist/all.scss 37542:173  @import
    src/assets/kendo.scss 2:9                                             @import
    src/assets/base.scss 1:9                                              root stylesheet

If I import directly the kendo-theme-bootstrap scss file in the main.js or the App.vue, there is no error. Here is the StackBlitz reproducing the error:

https://stackblitz.com/edit/vitejs-vite-f63fqh

How can I resolve this ?

License activation failed for @progress/kendo-ui v2023.1.425

I'm getting the following in my Debug Console when I run my application;

License activation failed for @progress/kendo-ui v2023.1.425
No license found.
See https://docs.telerik.com/kendo-ui/intro/installation/using-license-code for more information.

This despite having the license file present in my project root. At the moment, I have removed the environment variable since I thought it might be causing a conflict.

I have also used npm uninstall to remove all my local packages and I have reinstalled the. Her eis my current package.json;
