How to pass column value of grid in EditorViewData("#=?#")

[Prakash Kumar Nambi]

Grid :-

.Columns(columns =>
{
    columns.Bound(x => x.Role).Title("<b>Project OBS Role</b>").Width("30%").Filterable(true).
    HeaderHtmlAttributes(new { style="text-align:center;"}).HeaderHtmlAttributes(new { style = "text-align:center;vertical-align:middle;" });

    columns.Bound(x => x.UserId).Title("<b>Approver</b>").Width("40%").EditorTemplateName("GridGroupPeoplePicker").
   ====>  EditorViewData(new { SecurityGroup = "#=SecurityGroup#" }).Filterable(true).HeaderHtmlAttributes(new { style = "text-align:center;vertical-                     align:middle;"       }).HtmlAttributes(new { style = "text-align:left;" });

    columns.Bound(x => x.Delay).Title("<b>Delay<b>").Width("20%").Filterable(true).
    HeaderHtmlAttributes(new { style = "text-align:center;vertical-align:middle;" }).HtmlAttributes(new { style = "text-align:left;" });

    columns.Command(command => { command.Edit().Text(" ").CancelText(" ").UpdateText(" ");}).Width("10%").
    HtmlAttributes(new { style = "text-align:center;" });
})

 

Editor Template :-

@model string
@{
    string Groups = ViewData["SecurityGroup"] as string;
}
<input type="hidden" id="hdn@(Html.IdForModel())" data-bind="value: @(Html.IdForModel())" disabled="disabled" />
<input type="hidden" id="GroupName_@(Html.IdForModel())" data-bind="value: @(Groups)" disabled="disabled" />
<script>
    function GetGroups_@(Html.IdForModel())(e) {
        debugger;
        var filterInput = $('#hdn@(Html.IdForModel())').val();
        var Groups = $('#GroupName_@(Html.IdForModel())').val();
        return { PickerFilter: filterInput, GroupNames: '@Groups', IsUsersByGroup: 'false' };
    }
</script>
@(Html.Kendo().DropDownListFor(m => m)
        .DataValueField("Value")
        .DataTextField("Text")
        .Filter(FilterType.Contains)
        .MinLength(3)
        .AutoBind(false)
        .DataSource(ds =>
        {
            ds.ServerFiltering(true).Read(r => r.Action("GetUserByGroups", "Common").Data("GetGroups_" + Html.IdForModel()));
        })
)

Hello,

I can suggest reviewing this forum thread where the same scenario has been discussed. In general, the editor templates used for the Grid initialization come from the server and are evaluated only once, at initialization and against an empty model - that is why when the EditorTemplate is generated the passed "SecurityGroup" will be null or the default value for the property. 

As suggested in the thread you can use a .Data handler to access the edited model and get the required additional data.
