Be able to bind the DataSource to data without a separate controller and AJAX fetch for use with Razor Pages.

The use case is a shared data source that drives multiple components on a page for example a chart and grid filtered with an auto complete box.

In a grid I can do this:

@(Html.Kendo().Grid(Model.Data)
    .Name("Grid")
    .Columns(columns =>
    {
        columns.Bound(p => p.Description).Title("Description");
        columns.Bound(p => p.RecordCount).Title("Number Sold").Width(130);
        columns.Bound(p => p.TotalValue).Title("Total Value").Width(130);
        columns.Bound(p => p.AverageValue).Title("Average Value").Width(130);
        columns.Bound(p => p.Rank).Title("Rank").Width(130);
        columns.Bound(p => p.RankMax).Title("Bananas").Width(130);
        columns.Bound(p => p.LowerQuartile).Title("LowerQuartile").Width(130);
        columns.Bound(p => p.Median).Title("Median").Width(130);
        columns.Bound(p => p.UpperQuartile).Title("UpperQuartile").Width(130);
    })
    .Sortable()
    .DataSource(dataSource => dataSource
        .Ajax()
        .PageSize(20)
        .ServerOperation(false)
    )
)

Would want to be able to do same with the DataSource like:

@(Html.Kendo().DataSource(Model.Data)
    .Name("dataSource1")
    .Ajax(dataSource => dataSource
        .ServerOperation(false)
    )
    )

Even when using server side paging some requests can be very long, and may be canceled by the user.  Adding a CancellationToken parameter to the ToDataSourceResultAsync.

Hi guys,

I found out, that the QueryableExtension always generates a ToLower for strings filtered with the equals operator. The ToLower is applied by the FilterOperatorExtensions in this method:

    private static Expression GenerateEqual(
      Expression left,
      Expression right,
      bool liftMemberAccess)
    {
      if (left.Type == typeof (string))
      {
        left = FilterOperatorExtensions.GenerateToLowerCall(left, liftMemberAccess);
        right = FilterOperatorExtensions.GenerateToLowerCall(right, liftMemberAccess);
      }
      return (Expression) Expression.Equal(left, right);
    }

It would be nice, if the to lower is controllable with a parameter. At the moment it generates a to lower in the sql query, which generates a lot of overhead in some situations with large tables.

At the moment I remove all "equal to" filter and apply it manually to the IQueryable object.

Best regards

Hello,

At the moment I'm using the ImageBrowser in the Kendo editor.

A user contacted me and reported she would like to browse through the images in the ImageBrowser in a list view instead of tile view (thumbnails with text).

However, I couldn't find a suitable way to achieve this.

Does the current imagebrowser/editor have this functionality and if so, could you help me achieve this please?

Kind regards,

Joran

At current when working with the french culture, the year in the date will default be represented with 2Y (dd/MM/yy)

This potentially creates a problem for dates>2030, a date like 01/01/30 would be save as 1930 instead of 2030. 

When looking at other culture such nl-BE, en-GB, 4 digits are always used for the year.

I propose to change this also for the french culture so that dd/MM/yyyy would become the standard format.

PS: You can download the culture file and change it, but you'd experience a problem with the popup editor in combination with a display template... in this case the local culture file will be ignored and 2 digits would still be used for the date

When using .BindToLocation(true) it would be great if the developer had either a .Skip(string) or .Skip(string array) (or .Exclude(string) or .Exclude(string array).

This is useful because in ASP.NET Core when using Razor Pages, the site can be organized into Folders.  That Folder structure shows up in the URL even though there might not be an equivalent page.

As an Example, I have the following folder structure:

Pages --> Alerts --> AlertAvailableUnits 

The resulting URL in ASP.NET Core is:

https://localhost:44313/Alerts/AlertAvailableUnits 

Now, let's say I have the following Breadcrumb definition:

@(Html.Kendo().Breadcrumb()
.Name("breadcrumb")
.BindToLocation(true)
.Navigational(true))

This results in the following Breadcrumb:

Home > Alerts > AlertAvailableUnits

However...if I had an Exclude or Skip function then I could create the following definition:

@(Html.Kendo().Breadcrumb()
.Name("breadcrumb")
.BindToLocation(true)
.Navigational(true)
.Skip("Alerts"))

// OR As a String Array

@(Html.Kendo().Breadcrumb()
.Name("breadcrumb")
.BindToLocation(true)
.Navigational(true)
.Exclude(["Alerts"])

This would result in the following Breadcrumb:

Home > AlertAvailableUnits

This is what I'm after.  Since BindingToLocation has to parse the URL anyway to produce the Breadcrumb, then the Developer should have a way to Exclude or tell it to ignore/skip a part of the URL.

This would be complementary to my previously requested Breadcrumb Feature .IgnoreLastXSegments(integer).

The difference between the two is -- in the .Exclude/Skip case the segment I want to ignore is Known and occurs (usually) in the middle of the URL.  In the IgnoreLastXSegments, the URL contains parameters that always show up at the end.

Implementing these Features would make the BindingToLocation feature much more useful and promotes code reuse.  It is also a much simpler implementation than defining Items which does not promote code reuse.

Thanks for your consideration.

I am looking for an extension to the Grid Columns fluent api that adds .Exportable(true or false).  Exportable(true) would be the default and indicate that this column does get exported when exporting to Excel (or PDF).  Exportable(false) would indicate that the column does NOT get exported.

Imagine the following Grid Definition:

@(Html.Kendo().Grid<Services>
    ()
    .Name("gridMain")
    .Columns(columns =>
    {
        columns.Bound(p => p.ServiceId).ClientTemplateId("rowNumTemplate").Title("Row").Width(50);
        //columns.Bound(p => p.ServiceId).ClientTemplateId("cmdsTemplate").Title("Cmds").Width(125).Media("(min-width: 768px)");
        columns.Bound(p => p.ServiceCode).Media("(min-width: 768px)");
        columns.Bound(p => p.ServiceId).ClientTemplateId("xsTemplate").Title("Service / Desc / Code").Media("(max-width: 768px)");
        columns.Bound(p => p.ServiceId).ClientTemplateId("serviceTemplate").Title("Service / Desc").Media("(max-width: 992px) and (min-width: 768px)");
        columns.Bound(p => p.ServiceName).Media("(min-width: 992px)");
        columns.Bound(p => p.ServiceDescription).Media("(min-width: 992px)");
        columns.Bound(p => p.ServiceActive).ClientTemplateId("activeTemplate").Width(60).Media("(min-width: 768px)");
        columns.Bound(p => p.ServiceId).ClientTemplateId("btnsTemplate").Title("View/Edit/Del").Width(150);
        //columns.Bound(p => p.ServiceId).ClientTemplateId("xsCmdsTemplate").Title("Cmds").Media("(max-width: 768px)");
    })
    .Scrollable(scrollable => scrollable.Endless(true))
    .Pageable(p => p.Numeric(false).PreviousNext(false))
    .ToolBar(t => t.Search())
    .Search(s => { s.Field(c => c.ServiceCode); s.Field(c => c.ServiceName); s.Field(c => c.ServiceDescription); })
    .Resizable(resize => resize.Columns(true))
	.ToolBar(t => t.Excel().Text("Excel"))
    .Excel(excel => excel
		.FileName("ABT_Services.xlsx")
		.Filterable(true)
	)
    .DataSource(dataSource =>
    dataSource
    .WebApi()
    .PageSize(Model.GridPageSize)
    .Model(model =>
    {
        model.Id(p => p.ServiceId);
    })
    .Events(events => events.Error("errorHandler").RequestEnd("gridMainRequestEnd"))
    .Read(read => read.Action("Get", "Services"))
    )
)

What I would like to do is define a column like the following:

        columns.Bound(p => p.ServiceId).ClientTemplateId("rowNumTemplate").Title("Row").Width(50).Exportable(false);

In the case above, the "Row" column would not be Exported to Excel.

If you take a closer look at the Columns definition above you will see that the configuration is implemented to support responsive page sizing.  Because the current implementation of Export to Excel does not allow an Exportable(true/false), I get these columns that I don't want in the exported Excel.

Although there appear to be workarounds (like keeping a second hidden grid -- a poor solution at best), none would be as useful to a Developer as defining an Exportable(true/false) as part of the Column configuration.

Thanks for considering my request.

Hi,

I have tried to get the Timeline datasource to refresh when a datarow command in a grid is selected.

The gridrow has a patientid, and I would like to show a Timeline for the patient contact dates with the hospital.

The trouble is that the datasource for Timeline don't have the same functionality for filtering/parameters as the 'normal' datasource, and does not support .Data(..).

Example (not implemented in the Timeline datasource):

.Read(read => read.Action("GetSurgeryEvents", "TimeLine").Data("setTimeLineParam"))

I'm currently evaluating the ASP .Net Core Components and whilst I'm liking it so far, I have to say - the documentation leaves a lot to be desired.

At the moment, I am trying to use grid and looking at documentation, I have no idea if I am meant to be looking in Kendo.Mvc.UI.Fluent or Kendo.Mvc.UI - and when I am there and find an item, there just isn't enough detail. In addition, the demos section appears to actually be more helpful and I'm constantly looking there.

What caused me to write this is that I have simply enabled GridFilterMode.Row on an instance and whilst I like it, I want to change the default from "Is Equal To" to "Contains"... I have been experimenting for the past few hours without any luck and I'm going round in circles on documentation:

I can see that Filterable requires GridFilterMode, but the documentation is lacking - https://docs.telerik.com/aspnet-core/api/Kendo.Mvc.UI/GridFilterMode#kendomvcuigridfiltermode

I then try to find the filterable modes documentation, but, half the features/methods just don't seem to have any affect whatsoever.

Personally, I'm having great luck learning about your components from the demo section and adapting the code to suite my needs - but, if there isn't a demo, it appears to be a very hard task to learn what is and isn't possible.

As mentioned in this feature request for area-range chart series: "having area 'scatter' support, such as 'scatterArea', and 'scatterAreaRange', like the existing 'scatterLine', is also desirable".

Please see this forum post for details.

can we have the same functionalities as the AJAX html editor? 
There are a number of controls missing from the new editor that was not in the old telerik editor. including Add spell check, cut, copy and paste {several options}, undo, redo, new paragraph, horizontal rules, insert time, insert symbol. Anyway to bring those functionalities into  ASP.net core?

Add an option to configure a separate custom editor to be used when the Scheduler's mobile mode is enabled. This would make possible using two different templates at the same time, for example:

.Editable(editable => {
	editable.TemplateName("CustomEditorTemplate").MobileTemplateName("CustomEditorMobileTemplate");
})

Hello, 

Using Donut Chart with provided option for zooming and panning doesn't change appearance. 

  @(Html.Kendo().Chart()
        .Name("tagChart")
        .ChartArea(chartArea => chartArea
            .Background("transparent").Height(1200).Width(1200))

        .Title(title => title
            .Text("Dicom Tags")
            .Position(ChartTitlePosition.Bottom)
        )
        .Legend(legend => legend
            .Visible(false)
        )
        .SeriesDefaults(series =>
            series.Donut().StartAngle(15)
        ).Zoomable(z => z.Mousewheel(true))
        .Pannable(true)

Is any way to get it working? 

Thanks

I have a donut chart which represent as a circle and in middle of cricle there is some text, which needs to drilldown, hence click event need which is very necessary

Hi,

We have  a requirement for circled progress bar. Need to know whether you have specifications regarding the requirement or any optimization need to be done within the given framework to get the desired result. Please find the attached file for reference.
