MVC4 filter on custom parent GRID table value

[Dmitriy]

Hi,

I'm trying to filter on value from parent GRID  (dynamically)  
.Filter(filter => filter.Add(prod => prod.COUNTER_PRNITER_ID).IsEqualTo(decimal.Parse("# =PRINTER_ID#")))
But he try to parse the string not the value of printer id

the COUNTER_PRNITER_ID is the Forgen KEY of the PRINTER_ID (Parent KEY)

I want to show in the second GRID only the data that belong to selected printer
Kan somebody help me?

Thanks in advance

Sample code below

 @(Html.Kendo().Grid((IEnumerable<KendoUIMvcLoginApp.Models.Data.Printer>)ViewBag.Printers)
            .Name("grid")
            .Columns(columns =>
            {
                columns.Bound(e => e.PRINTER_NAME).Title("Printer Name");
                columns.Bound(e => e.PRINTER_IP).Hidden();
                columns.Bound(e => e.PRINTER_ID).Hidden();
                columns.Bound(e => e.PRINTER_MIB_ID).Hidden();
               
                columns.Command(command => command.Custom("Start").Click("showDetails")).Width(50);
            })
            .ClientDetailTemplateId("template")
            .DataSource(dataSource => dataSource
                .Ajax()
                .Read(read => read.Action("HierarchyBinding_Employees", "Grid"))
            )
            .Events(events => events.DataBound("dataBound"))
        )
   
        <script id="template" type="text/x-kendo-template">

                    .Animation(animation => animation.Open(open => open.Fade(FadeDirection.In)))
                    .Items(items =>
                    {  
                        items.Add().Text("Test Counters").Content(@<text>

I have found also the following:


.Filter(filter => filter.Add(prod => prod.COUNTER_PRNITER_ID).IsEqualTo(((KendoUIMvcLoginApp.Models.Data.Printer)(this.Ajax.ViewContext.ViewData.Model)).PRINTER_ID) )

but in this case i can see only the last id of my PRINTE_ID
i think it because the data of the first GRID is already posted

Hi Dmitriy,

 
Please note that we already provide such example in our CodeLibrary which demonstrates how to configure Grid Ajax to filter the child grid data:

• Grid Ajax Hierarchy Editing
