Bug report

A server side exception:
System.OverflowException: 'Value was either too large or too small for a Double.'
is thrown on attempting to serialize an existing .pdf file converted to FixedDocument.

Reproduction of the problem

1. Use the DPL Processing demo of the PDFViewer in the MVC demos project.
2. Instead of the default sample.pdf load the Development Plan.pdf file provided in Ticket ID: 1467984

public ActionResult GetInitialPdf(int? pageNumber)
{
    //exception with Development plan.pdf file:
    string filePath = Path.Combine(Server.MapPath("~/Content/web/pdfViewer"), "Development Plan.pdf");
    //it works with the sample.pdf file:
    //string filePath = Path.Combine(Server.MapPath("~/App_Data"), "sample.pdf");
    FileStream stream = new FileStream(filePath, FileMode.Open, FileAccess.Read);
    JsonResult jsonResult;
    FixedDocument doc = FixedDocument.Load(stream);

    if (pageNumber == null)
    {
        jsonResult = Json(doc.ToJson(), JsonRequestBehavior.AllowGet);
    }
    else
    {
        jsonResult = Json(doc.GetPage((int)pageNumber), JsonRequestBehavior.AllowGet);
    }

    jsonResult.MaxJsonLength = int.MaxValue;
    return jsonResult;
}

Current behavior

The exception is thrown during the FixedDocument JSON serialization:

doc.ToJson()

at the following place: ConvertToList method in ArrayExtension class (Telerik.Web.PDF namespace)

Expected/desired behavior

No exceptions are thrown during serialization.

Bug report

Currently the MultiSelect allows a custom tag (one that does not correspond to items in its dataSource) to be displayed as selected. For this to work the MultiSelect must have autoBind disabled and the dataValueField option must be set. Once the widget is bound to data it behaves inconsistently, depending on whether there are other pre-selected items and what their index in the dataSource is.

Reproduction of the problem

Dojo example.

1. Focus the MultiSelect

Current behavior

The widget is loaded with data, but the custom tag remains. This leads to the following unexpected behavior: after step 1. deselect "Product1". The item is deselected, the "custom" tag is removed from the input area but the "Product1" tag remains. The behavior is different, if initially "custom" and "Product2" are pre-selected.

Expected/desired behavior

Once the widget is bound any custom tags should be removed. The MultiSelect should display only tags for items that are in its dataSource. For a new item to be displayed as selected, it must be added to the dataSource.

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

Open the demo at https://demos.telerik.com/aspnet-mvc/filemanager

right click Images in the tree and click rename. 

Change the name

select the new folder name in the tree

try to do anything with the files in that folder (rename or delete are available in the demo)

= server error 500 

the path did not update to the new path.

but if you refresh you see the folder renamed and worked (and now you can do things with the files inside)

now if you add a folder inside Images and do the same process over again it works as expected...

Hello, our file manager makes 2 read request in a row when the page is loaded, when we load a new path, and when a directory is clicked in the tree view.

Is this normal?

Thanks!

https://demos.telerik.com/aspnet-mvc/grid/foreignkeycolumn

In addition to the Foreign Key editor template, populate a list which holds all the categories and pass it via the ViewData - you can see how this is done in the ForeignKeyColumnController.cs PopulateCategories() method.

On the above page, the above statement is made.  Other than the function call to PopulateCategories() I don't ever see the actual code run in the function shown anywhere.  Can someone please add that code and/or point me to my misunderstanding?

Thank you.

The method is not available for the MVC wrappers but it is available for ASP.NET Core.

Bug report

Regression introduced in R1 2020. Reproducible with the SASS themes, but the Kendo UI script version has effect on the behavior. For example, the behavior is not reproducible if the latest (2020.1.406) SASS theme is used along with an older (2019.2.1023) version of the kendo.all.min.js file.

Reproduction of the problem

Dojo example.

1. The behavior is exhibited when an event ends at the same time another event starts, as it is demonstrated in the dojo where "Interview" ends and "Meeting" starts at the same time - 06:15.

Current behavior

"Meeting" is displayed below and to the right of "Interview", similarly to how events are displayed when their time spans overlap.

Expected/desired behavior

"Meeting" should be displayed below "Interview".

• Kendo UI version: 2020.1.406
• jQuery version: x.y
• Browser: [all]

In the file manager after we move a *directory* with the Tree view (NOT list view), we are getting a javascript error:

kendo.all.min.js:114 Uncaught TypeError: e.closest is not a function
    at init._restoreFocus (kendo.all.js:166158)
    at r.proxy (jquery-3.3.1.js:10268)
    at r.trigger (kendo.all.js:164)
    at r._closeAnimationEnd (kendo.all.js:60234)
    at Object.proxy [as completeCallback] (jquery-3.3.1.js:10268)

    at Function.dequeue (jquery-3.3.1.js:4376)
    at HTMLDivElement.<anonymous> (jquery-3.3.1.js:4418)

This seems to be in kendo.all.js  and I believe it is being called after the modal closes

which I thinki s being called from this:

I think it's trying to locate the target of the directory that was moved - which is no longer there - and set focus to it.

I was trying to bind to the CLOSE event of the move dialog and set it to null to avoid the _restoreFocus call?

Not sure if that's even a good approach to take.

What are your thoughts?  Thank you.

I downloaded the latest version of Kendo UI (Version: 2020.1.406) for MVC and upgraded my project to refer the latest JS, CSS and Kendo.MVC (2020.1.406.545).

NoRecords method is behaving differently in the latest version. While fetching records in progress, it displays the 'No record found' message even before completion of the action method. Please see the below image:

It was not happening in the version 2018.2.516, it was showing the 'No record found' message after completion of the action method and only if there is 0 row returned.

Below is the code of Student.cshtml view:

View several folders in treeview of the filemanager:  folder1, folder2, folder3

select folder1

now Click and drag folder2 to folder3.

the folder1 moves to folder3.  

this is not desired.

can be reproduced in the demo

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

This is a regression introduced in R2 2019.
Textboxes and charts currently are not supported in the Spreadsheet, however, if the loaded excel file contains such, saving the file should not throw a js exception.

Reproduction of the problem

1. In Excel add a textbox and/or a chart to a workbook. Save the workbook. Alternatively, use the attached file:
   sample-new-chart-textbox.zip
2. Load the .xlsx file in the Spreadsheet
3. Save the file

Current behavior

On saving the file the following exception is thrown:
kendo.all.js:12938 Uncaught TypeError: Cannot read property 'target' of undefined

Expected/desired behavior

No js exceptions on saving the file.

Bug report

When using MVVM generated DropDownList input decorated with required attribute the validation message is not displayed upon validation.

Reproduction of the problem

1. Run this dojo
2. Click on a slot to create an event
3. Select an item from the second DropDownList
4. Click Save

Current behavior

Upon clicking Save the validation fails, as the first input has a required attribute, but a validation message is not displayed.

Expected/desired behavior

On failed validation, a validation message should be displayed.

First of all, we are using the 'Telerik UI for ASP.NET Core' product. We would like to ask you about the PivotGrid component, since we are having a strange behavior with the application of filters on the dimensions once the PivotGrid shows the data.

The use case is as follows:

1. We configure the PivotGrid applying two dimensions, one in a column (‘family_name’) and the other in rows (‘bc_name’) and select a measure (‘Amount’), and the PivotGrid is generated as expected. (see Case1.png)
2. We apply one filter to the columns, for example ‘family_name’ contains ‘OJOS’, and the PivotGrid is refreshed showing only the data filtered as expected. (see Case2.png and Case3.png)
3. We apply another filter to the rows, for example ‘bc_name’ contains ‘Barrios’, and the PivotGrid is refreshed showing only the data filtered by that filter, but no for the combination of the filter of ‘family_name’ applied before. (see Case4.png and Case5.png)

As you can see, the behaviour is strange, because we we can’t see the data with the application of both filters in combination.

I also included the code where we build the PivotGrid, if that can help to see the problem. (see Code.txt)

Hope that you can help us, because that is a real inconvenient for us.

 Thanks in advance.

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.
