ForeignKey and UIHint

[Louis]

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?

Hi Louis,

 

This requirement is actually possible. You can follow the implementation demonstrated in this live sample to achieve this:

I hope this will prove helpful.

Hello Eyup,

Hummm not really but I found the solution elsewhere.

Have great week-end.

If you are still on the forums, can you please post the solution.

Hi Trent,

Thank you for reaching out.

Indeed, internally, the Grid ForeignKey column will use a default DropDown editor, and thus the observed behavior will occur. Having this in mind, the ForeignKey() method has an overload, where you can specify that the column should use a server editor ("useServerEditor" boolean parameter):

https://docs.telerik.com/aspnet-core/api/kendo.mvc.ui.fluent/gridcolumnfactory#foreignkeysystemlinqexpressionsexpressionsystemactionsystemstringsystemstringsystemboolean

To enable the custom editor template, please update the column configuration as per the example below:

.Columns(columns =>
{
    columns.ForeignKey(p => p.FirmID,ds=>ds.Read(r=>r.Action("GetFirms","Home")), "FirmID", "FirmName",true)
      .Title("Firm").EditorTemplateName("FirmGridForeignKey").Width(250);
})

For your convenience, I am also attaching a runnable sample that showcases the mentioned above. Please give the suggestion a try and let me know how it works out for you.

I hope this helps.
