Show dropdownlist value on update state

[Xavier]

Hi,

We have a grid with a foreignkey column. This column has to call an edit template Dropdownlist with cascade property .

columns.ForeignKey(f => f.CatalogReference, (System.Collections.IEnumerable)ViewBag.Cataleg, "Reference",          "Descripcio").EditorTemplateName("CatalegReferenceByType");

@model object
(Html.Kendo().DropDownList()
    .Name("CatalogReference")
    .AutoBind(true)
    .OptionLabel("Select reference...")
    .DataTextField("Descripcio")
    .DataValueField("Reference")
    //.HtmlAttributes(new { data_skip = "true", data_bind = "defferedValue: object" })           //.BindTo((SelectList)ViewData[ViewData.TemplateInfo.GetFullHtmlFieldName("") + "_Data"])
    .DataSource(source => {
           source.Read(read => read.Action("PopulateReferences", "Catalog").Data("filterTypes"))
          .ServerFiltering(true); })
    .CascadeFrom("Tipus")
    .HtmlAttributes(new { id = Guid.NewGuid().ToString() })
)

It's possible show the value in dropdownlist when update state is selected.


Thanks for your responds.

Hi Xavier,

Basically, the ForeignKey helper is used to populate the columns.values array. This array is used to that the Grid can match the field values with the corresponding text that should be shown. In case the user selects an item that is not present in the columns.values array the cell will show up empty. As a workaround you can get and update the columns configuration, so that the array includes the selected item and update the Grid using the setOptions method.
