[Solved] Child Grid data source action never called

[Mutuhraj]

Hello,
I am having a grid which will show the driver detail and if the use expands one row then I want to show the some information of that driver in another grid.

Below is my code
 <%: Html.Kendo().Grid<PrimeWebInterface.Views.ViewModels.DriverViewModel>()
                 .Name("DriverRoute")
            .Columns(columns =>
            {
                columns.Bound(e => e.Code);
                columns.Bound(e => e.Name);

            })
            .Sortable()
            .Pageable()
            .Scrollable()
            .ClientDetailTemplateId("template")
            .HtmlAttributes(new { style = "height:430px;" })
            .DataSource(dataSource => dataSource
                .Ajax()
                .PageSize(6)
                 .Read(read => read.Action("Bind_Drivers", "DriverRoute"))
            )
            .Events(events => events.DataBound("dataBound"))
    %>

    <script id="template" type="text/kendo-tmpl">
        <%: Html.Kendo().Grid<PrimeWebInterface.Views.ViewModels.DriverRouteGrid>()
                .Name("DriverRoute_#=Code#")
                .Columns(columns =>
                {
                    columns.Bound(o => o.RouteDate);
                    columns.Bound(o => o.ItinaryCode);
                    columns.Bound(o => o.RouteID);
                })
                .DataSource(dataSource => dataSource
                    .Ajax()
                    .PageSize(5)
                    .Read(read => read.Action("Bind_Itinary", "DriverRoute", new { code ="#=Code#" }))
                )
                .Pageable()
                .Sortable()
                .ToClientTemplate()               
        %>
    </script>
    <script>
        function dataBound() {
            this.expandRow(this.tbody.find("tr.k-master-row").first());
        }
        
    </script>
</asp:Content>

Code (string type) is the primary field. With the above code I can able to see the parent records (Driver) and the child grid not showing any records.


Since I am new to this , I might have missed some setting. So, Could you please guide me to solve this issue.?

Thanks and Best Regards

Hello Mutuhraj,

The Grid setup looks correct to me. Do you see any JavaScript errors when the detail Grid gets expanded? When you inspect that browser console `Network` tab are there any failed requests with server errors or something? Is your controller and action method correctly implemented?

Hello Mutuhraj,

You are missing kendo.aspnetmvc.min.js in your script section:

<script src="../../Content/js/jquery.min.js"></script>
<script src="../../Content/js/kendo.all.min.js" type="text/javascript"> </script>

<!-- you must add the following script too -->
<script src="../../Content/js/kendo.aspnetmvc.min.js" type="text/javascript"> </script>

See step 5 from the following article for more details: Using Kendo UI in ASP.NET MVC application
