Hi,

I am trying to add an area of best fit to a standard scatter plot: I have one set of data points, and two equations for lines of best fit. The desired result is a scatter plot of the data points with a shaded area between the two lines of best fit.

I understand that it is currently not possible to mix categorical and XY charts (https://www.telerik.com/forums/using-area-and-scatter-chart-types-in-one-chart). I have tried drawing the desired area on the scatter chart as per https://docs.telerik.com/kendo-ui/controls/charts/how-to/appearance/draw-on-scatter-plots, however this results in the area being superimposed on the chart surface and prevents user interaction with the data points (tool-tips etc.) so is not an acceptable solution.

Is there any other way to achieve the desired result? Please see attached for a simplified example of what I'm trying to achieve.

DropDownLists Shared Datasource binding to subobject of model

Hello,

I have a shared datasource that returns a model that has four lists

Model:

public class BillModel : DocumentBaseModel

{

...

public List<HistoryModel> History { get; set; }
public List<AmendmentModel> Amendments { get; set; }
public List<OtherDocModel> OtherDocs { get; set; }
public List<PreviousVersionModel> PreviousVersions { get; set; }

}

Shared Datasource:

@(Html.Kendo().DataSource<BillModel>()
.Name("myDataSource")
.Custom(dataSource =>
{
dataSource
.Type("json")
.Transport(transport =>
{
transport.Read(read =>
{
read.Action("GetBill", "Bills", new { billNo = "#=Id#" });
});
});
})
)

And one of my DDLs:

@(Html.Kendo().DropDownList()
.Name("amendments")
.DataTextField("Name")
.DataValueField("LFID")
.DataSource("myDataSource")
.HtmlAttributes(new { style = "width: 100%" })
.ToClientTemplate()
)

DropDownLists Shared Datasource binding to subobject of model

Hello,
I have a model with a few lists. I am trying to use a shared datasource to populate a dropdownlist for each of these lists but I am having trouble with how to refer to a specific subobject within the object that is returned from the controller. I’m sure that this has been done before… I’m just having trouble finding an example.

My model looks like this:
public class BillModel : DocumentBaseModel
    {
        …

        public List<HistoryModel> History { get; set; }
        public List<AmendmentModel> Amendments { get; set; }
        public List<OtherDocModel> OtherDocs { get; set; }
        public List<PreviousVersionModel> PreviousVersions { get; set; }
    }

My controller returns the BillModel
My view has a grid that accesses a ClientTemplate that has three ddls and my shared datasource.
@(Html.Kendo().DataSource<BillModel>()
.Name("myDataSource")
       .Custom(dataSource =>
       {
              dataSource
                     .Type("json")
                     .Transport(transport =>
                     {
                           transport.Read(read =>
                           {
                              read.Action("GetBill", "Bills", new { billNo = "#=Id#"});
                            });
                     });
       })
)
@(Html.Kendo().DropDownList()
.Name("amendments")
       .DataTextField("Name")
       .DataValueField("LFID")
       .DataSource("myDataSource")
       .HtmlAttributes(new { style = "width: 100%" })
.ToClientTemplate()
)

@(Html.Kendo().DropDownList()
.Name("others")
       .DataTextField("Name")
       .DataValueField("LFID")
       .DataSource("myDataSource")
       .HtmlAttributes(new { style = "width: 100%" })
.ToClientTemplate()
)

@(Html.Kendo().DropDownList()
.Name("previous")
       .DataTextField("Name")
       .DataValueField("LFID")
       .DataSource("myDataSource")
       .HtmlAttributes(new { style = "width: 100%" })
.ToClientTemplate()
)

How do I get each ddl to use their list from the datasource? I thought perhaps I could use dot notation and write .DataTextField(“Amendments.Name”). It didn’t yell at me it just said undefined. I’m sure it must be something simple I just can’t figure it out today.

ExportToPdf works local, not production.

My project is core but this is really just simple view. I want to convert some simple html to pdf and "Save As" to the local machine. I dumbed down my actual view fo the example but please help me understand why this works (pdf is generated and saved to downloads) on my local machine but not in production (tried in Chrome/Edge/IE).

Heres a dojo link; http://dojo.telerik.com/@bdaun1@gmail.com/ (doesn't work here either... only when I run in dev on my machine)

Thanks!

Is editing and mail merge functionality for document processing available for ASP.Net Core?

I've been looking through demos of document processing, and I'm only seeing format conversion in the demos for ASP.Net Core. When I view demos for document processing for ASP.Net MVC, I see mail merge and other functionality. Is mail merge and editing also supported in UI for ASP.Net Core?

.NET Core extension to create project not working

Hello,
Out of the box, using the 'Telerik UI for ASP.NET Core' -> Create New Telerik Project (Grid and Menu) extension in Visual Studio 2019 + .NET Core 3.0 does not appear to work correctly. The project will get created and will build and run correctly, however when I try to add a new View or Controller I will get the attached error. I kept adding libraries that the error was complaining about until it worked, however I'm not sure this was the correct way to go about fixing this (see attached).

Is there a reason the out of the box extension to create a project is not working?
I've submitted a bug regarding this as well.

Thanks,
Dave

dotnet CLI installs a wrong Nuget version for AspNet.Core

Hello,
we are currently following this guide (https://docs.telerik.com/aspnet-core/getting-started/first-steps-cli)
to setup Telerik UI for ASP.NET Core 3.0.100 (not RC).
After we run "dotnet add package Telerik.UI.for.AspNet.Core" we see that the version "2016.3.914" is downloaded and installed, and NOT the version "2019.3.917" we see from here: https://www.telerik.com/account/product-download?product=UIASPCORE
Obviously with old this version "dotnet run" throws errors.

What are we missing?

We tried to downgrade to dotnet SDK 3.0.100-RC but nothing changes.
Forcing installing the specific version with "dotnet add package Telerik.UI.for.AspNet.Core -v 2019.3.917" returns error "Unable to find package Telerik.UI.for.AspNet.Core with version (>= 2019.3.917)"
Our platform is Linux and we downloaded dotnet sdk from here https://dotnet.microsoft.com/download/thank-you/dotnet-sdk-3.0.100-linux-x64-binaries
We have trial license of Progress® Telerik® UI for ASP.NET Core

Thanks for your support

my nuget.config

<?xml version="1.0" encoding="utf-8"?>

    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
