Bug report

TextAreaFor editor is missing in ASP.NET Core and ASP.NET MVC wrappers.

Environment

* **Kendo UI version:** 2020.3.915
* **jQuery version:** 1.12.4
* **Browser:** [all] 

Dear support,

Your documentation clearly states that there is an option to export all pages:

Exporting All Data

By default, the Telerik UI TreeList for ASP.NET MVC exports only the current page of data. To export all pages, set the AllPages option to true.

@(Html.Kendo().TreeList<Kendo.Mvc.Examples.Models.TreeList.EmployeeDirectoryModel>()
    .Name("treelist")
    .Toolbar(tools => tools.Excel())
    .Excel(excel => excel.AllPages(true))
    .DataSource(dataSource => dataSource
        .Read(read => read.Action("All", "EmployeeDirectory"))
    )
)
 
However, when I try this, AllPages gives a compiler error:
Severity	Code	Description	Project	File	Line	Suppression State
Error	CS1061	'TreeListExcelSettingsBuilder<dynamic>' does not contain a definition for 'AllPages' and no accessible extension method 'AllPages' accepting a first argument of type 'TreeListExcelSettingsBuilder<dynamic>' could be found (are you missing a using directive or an assembly reference?)	StarPMWeb	C:\TFS2015\StarPMWeb\StarPMWeb.root\MAIN\Enhancements\WIPProvisions_MR\StarPMWeb\Areas\WIPPROVISIONS\Views\ParentChildPeriod\_RenderParentChildEditPeriodGrid.cshtml	706	Active
Why is this happening? Is your documentation just wrong?
I am using version 2020.1.114
If this AllPages option is not currently implemented, can you please add this to the roadmap? It seems to be a strange omission.
Thanks.

Bug report

The responsive pager of the grid is shown when the width of the window is a few pixels above 1024 but less than 1035.

Reproduction of the problem

Dojo sample for reproduction:

https://dojo.telerik.com/oNejEYOz

1. Resize the browser to be around 1025 pixels. Just after showing the full pager, refresh the page.

2. The responsive pager is shown.

Expected/desired behavior

The full pager should be shown.

)

For a sample project, contact Ivan Danchev or Georgi Yankov.

Reproduction of the problem

If one of the columns (e.g. Field6) has a long header title calling the autoFitColumn and passing the column to it does not properly resize the column. The column remains narrow and its header text remains cut off.

Similarly, the method does not have the expected effect on columns with shorter text in the header, i.e. they remain wide instead of shrinking to the text length.

Current behavior

Incorrect column resizing.

Expected/desired behavior

Correct column resizing.

Environment

Bug report

Reproduction of the problem

The configuration for scale.rangeSize is not available for UI for ASP.NET MVC Wrappers (works with .NET Core)

Current behavior

When attempting to set the scale.rangeSize, the following error appears:

Error CS1061 'GaugeLinearScaleBuilder' does not contain a definition for 'RangeSize' and no accessible extension method 'RangeSize' accepting a first argument of type 'GaugeLinearScaleBuilder' could be found (are you missing a using directive or an assembly reference?)

Expected/desired behavior

This configuration should be included in future releases.

Environment

• Kendo UI version: 2020.2.513

Bug Report

When the grid is bound to an external dataSource, the AutoBind(false) setting is not serialized and as a result, the grid binds immediately

Reproduction

• Take the basic usage grid demo https://demos.telerik.com/aspnet-mvc/grid/basic-usage
• Extract the data source and set it to the grid
• set AutoBind(false)

    @(Html.Kendo().DataSource<Kendo.Mvc.Examples.Models.CustomerViewModel>()
    .Name("myDs")
    .Ajax(r=>r.Read(a=>a.Action("Customers_Read", "Grid")))
    )
    @(Html.Kendo().Grid<Kendo.Mvc.Examples.Models.CustomerViewModel>()
        .Name("grid")
        .AutoBind(false)
        .DataSource("myDs")
        /* other settings */
    )

Current Behavior

Expected Behavior

The grid should not bind initially.

Environment

Kendo UI version: 2020.2.617

Bug report

Regression introduced in R2 2019.

Reproduction of the problem

Dojo example.

1. Focus the empty line between the two lines with text
2. Press Backspace key

Current behavior

The line is not deleted

Expected/desired behavior

The line is deleted

Another scenario:

1. Click at the beginning of the third line (before "Du").
2. Press Backspace key
3. Press Delete key.

Delete has no effect if Backspace is pressed before that. If you continue pressing Delete, it will work, but once you press Backspace, the next time you press Delete, it won't delete the character that follows the cursor position.

If a large number of files are moved using the drag & drop feature, it is very likely that some will get permanently deleted in the process. This is due to the Destroy routine being initiated before the Create routine has completed. Using the demo page here https://demos.telerik.com/aspnet-mvc/filemanager I've been able to replicate the loss of files. Steps are simply:

• Create a new folder inside the Images folder
• Drag the 10 images into this new folder
• Drag them back
• Repeat
•  

Almost immediately, you will find there's no longer 10 images as the Create routine fails to complete before the Destroy routine is initiated resulting in 1 or more files being lost. With very little effort, I was able to reduce the 10 images down to 6 - I would class this as critical.

After 1 move operation, the 10 files are now just 8:

When using the Telerik upgrade wizard I get a error while upgrading my web app:

Bug report

Reproduction of the problem

1. Go to the Themebuilder page
2. Select BlueOpal theme
3. Modify the "Error" color.
4. Download the custom theme

Current behavior

The generated kendo.custom.css file contains the following rule:

undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined undefined .k-text-error {
  color: #7030a0;
}

Expected/desired behavior

The rule should have correct selector, or if it is redundant it should not be included in the file.

There is empty title attribute of PDFViewer zoom level combobox

Reproduction of the problem

1. Go to https://demos.telerik.com/kendo-ui/pdfviewer/index
2. Inspect the zoom level combobox

Current behavior

Empty "title" attribute

Expected/desired behavior

The "title" attribute of the combobox explains the purpose of the combobox, e. g. Zoom level combobox

Hey,

I might have found another bug.

The "Change" Event isn't triggered for checkboxes if GroupPaging is set to true.

If it's disabled, the event gets caught as expected.

.Name("whitelistGrid")

                   {
                       c.Bound(x => x.Id).Hidden();
                       c.Select().Width(50);

The Workbook.FromDocument() method freezes the panes based on the coordinates of the TopLeftCellIndex of the pane instead of the XSplit and YSplit properties of the pane. Reproduced with the attached Excel file

• https://github.com/telerik/kendo/blob/master/dpl/Telerik.Web.Spreadsheet/Models/Workbook.FromDocument.cs#L50

var pane = documentWorksheet.ViewState.Pane;
if (pane != null && pane.State == PaneState.Frozen)
{
    sheet.FrozenRows = pane.TopLeftCellIndex.RowIndex;
    sheet.FrozenColumns = pane.TopLeftCellIndex.ColumnIndex;
}

Solution:

var pane = documentWorksheet.ViewState.Pane;
if (pane != null && pane.State == PaneState.Frozen)
{
    sheet.FrozenRows = pane.YSplit;
    sheet.FrozenColumns = pane.XSplit;
}

WORKAROUND: Loading the Excel file with DocumentProcessingLibrary API and change the pane

var fileName = <YourFilePathHere...>;
if (!File.Exists(fileName))
{
    throw new FileNotFoundException(String.Format("File {0} was not found!", fileName));
}

Telerik.Windows.Documents.Spreadsheet.Model.Workbook workbook;
IWorkbookFormatProvider formatProvider = new Telerik.Windows.Documents.Spreadsheet.FormatProviders.OpenXml.Xlsx.XlsxFormatProvider();

using (Stream input = new FileStream(fileName, FileMode.Open))
{
    workbook = formatProvider.Import(input);
    foreach (var sheet in workbook.Worksheets)
    {
        if (sheet.ViewState.Pane != null && sheet.ViewState.Pane.State == Telerik.Windows.Documents.Spreadsheet.Model.PaneState.Frozen)
        {

            var originalPane = sheet.ViewState.Pane;
            var pane = new Pane(new CellIndex(originalPane.YSplit, originalPane.XSplit), originalPane.XSplit, originalPane.YSplit, originalPane.ActivePane);
            sheet.ViewState.Pane = pane;
        }
    }
}
var sheets = Telerik.Web.Spreadsheet.Workbook.FromDocument(workbook).Sheets;

Bug report

When a table is created through the table wizard and cellspacing is set to 0, this value is ignored and the table is created with no cellspacing value. 0 is a valid value and it affects the appearance of the table, so it should not be equivalent to not setting cellspacing.

Reproduction of the problem

Reproducible in the demos.

1. Use the table wizard.
2. Set 0 as cellspacing value.
3. Create the table.
4. Inspect the table in the browser's dev tools.

Current behavior

The table has no cellspacing attribute.

Expected/desired behavior

The table has cellspacing set to 0.
