I have a grid whereas the columns are defined as: 

.Columns(columns =>
{
    columns.Bound(b => b.Field);
    columns.Bound(b => b.OldValue);
    columns.Bound(b => b.NewValue);
    columns.Bound(b => b.DateImported).Format("{0:dd-MMM-yyyy}");
    columns.Bound(b => b.BuildingChangeValidationStatusType).ClientTemplate("#=BuildingChangeValidationStatusType.Value#").Width(250);
    columns.Command(command => command.Custom("Update").Click("updateValidation"));
    columns.Command(command => { command.Edit(); }).Width(172);
})

The BuildingChangeValidationStatusType client template is defined as: 

@model Rep.Models.BuildingChangeValidationViewModel
@(Html.Kendo().DropDownList()
    .Name("BuildingChangeValidationStatusType") // Name of the widget should be the same as the name of the property
    .DataValueField("Id")
    .DataTextField("Value")
    .BindTo((System.Collections.IEnumerable)Model.BuildingChangeValidationStatuses)
)


I am wanting to pass the model for each row to the client template since each row will contain its own lookup values.  How can I accomplish this?

Hi Dave,

From the provided information it's not clear for us what exactly you are trying to achieve and what is the current Grid configuration that you are using, however if you need to filter the DropDownLists based on current model than you can use the following approach:
- Set DataBound event handler:
.Events(e => e.DataBound("dataBound"))

- Add the event handler before DropDownList initialization code:
<script>   
    var globalFlag = false;
    function dataBound(e) {
        //execute only once
        if (!globalFlag) {
            var row = this.wrapper.closest("tr");
            var grid = row.closest("[data-role=grid]").data("kendoGrid");
            var model = grid.dataItem(row);
            globalFlag = true;
            this.dataSource.filter({ field: "Text", operator: "startswith", value: "Ax" });
        }
    }
</script>
       
@(Html.Kendo().DropDownList()
