javascript error when model for DropDownListFor is null

[Alex]

 

I have a grid that has a column bound to it:

columns.Bound(p => p.FailureStrategyLookup).ClientTemplate("#=FailureStrategyLookup.FailureStrategy#").Width(100);

 

If the FailureStrategyLookup is NOT null, everything works fine. But when it IS NULL it can't bind the the object and I get an error saying "FailureStrategy" can't be found for a null value (or something to that affect). How can I get thsi working for a COMPLEX type when it's null?

 

public class FailureStrategyLookupViewModel
{
    [Required]
    public int FailureStrategyID { get; set; }

    [Required]
    [DisplayName("Maintenance Strategy")]
    public string FailureStrategy { get; set; }
}

@using eRPortalDashboard.Models;
@using Kendo.Mvc.UI;

@model FailureStrategyLookupViewModel

@(Html.Kendo().DropDownListFor(m => m)
    .DataValueField("FailureStrategyID")
    .DataTextField("FailureStrategy")
    .BindTo((System.Collections.IEnumerable)TempData["FailureStrategyLookups"])
)

Hello Alex,

From the provided information it seems that the source if the issue is the column template that you are using. In order to support null values you should access the nested fields only if the parent field is not null. Please check the updated code below:

.ClientTemplate("#=FailureStrategyLookup ? FailureStrategyLookup.FailureStrategy : 'no value'#")
