Hello, 
I checked kendo version 2018.02.620 with Core 2.2 and Core 3.
in the first case, the app works successfully
in the second case, the app does not work.
Have you a plan to release a fix in order apps to work with kendo version 2018.02.620 and Core 3?

Thanks in advance for your answer.

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.

David

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()
                 )

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.

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!

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?
