Foreign Key Column Filter

[Hannes]

Hi there,

i am using a ForeignKeyEditor in the Grid like this

GridForeignKey.cshtml:

@model object

@(
        Html.Kendo().DropDownListFor(m => m)
            .Filter(FilterType.Contains)
            .BindTo((SelectList)ViewData[ViewData.TemplateInfo.GetFullHtmlFieldName("") + "_Data"])
)

This works however filtering is not working as expected.

If I use the above code the column displays *all* values and not the distinct values that are actually used.

Checking the documentation it states:

By default, the Grid internally matches the values collection in the column with the corresponding value field from the dataItem and creates a collection with the unique values for the filtering of the foreignKey column.

So why is this not working with the above code?

Hi Hannes,

I have tested the foreign key column editor on my end but the editor contains only distinct items.

For your convenience I am attaching the sample I used for testing. Please examine it and let me know what I am missing. Have in mind that it will be necessary to restore all references.

I look forward to your reply.

Hi Georgi,

your example is for ASP.NET MVC and not ASP.NET MVC CORE.

Please provide a sample which is using Telerik.UI.for.AspNet.Core   

Thank you

Hi Hannes,

I apologize for the inconvenience.

Indeed I sent a MVC sample. However, I have tested the very same configuration in a ASP .Net Core sample and still the editor is populated with the distinct items.

Attached you will find the sample I used for testing. Please examine it and let me know what I am missing.
