I just installed the Telerik UI for ASP.Net Core VS extension and when I start a new project, I get 3 options of the same thing?
how to validate the required field
which i define it the class as Required
example
[Required]
public string Title { get; set; }
[Required]
public string Description { get; set; }
when i create new Record in grid asp.net Core
then i press Save button directly catch the controller with out any validation
there is event in the grid
.Events(e => e.Error("error"))
<script>
function error(e) {
console.log(e);
if (e.errors) {
var message = "Errors: \n";
$.each(e.errors, function (key, value) {
if ('errors' in value) {
$.each(value.errors, function () {
message += this + "\n";
});
}
});
alert(message);
}
};
</script>

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.
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!

Hello,
It's seem that ForeighKey always use GridForeignKey.cshtml…
I try to decorate the attribute UIHint with another cshtml (Shared/EditorTemplates) and it's not working. My dropdown list in the grid always use GridForeignKey.cshtml.
Any idea?
