[saivikki]

I had many to many associated table sample data will be like the below sample,

I need to show company details as the parent and employee details as the child.

Also i need to edit the employee details, 

I have tried the Hierarchy grid MVC Syncfusion EJS 1, But it the field name provided in querystring need to be in the child data, In Many to Many associated data it won't have.

Hi Saivikki, 

  

Thanks for contacting Syncfusion support, 

  

We have prepared sample based on your requirement. We have achieved your requirement using “Created”, “dataBound”,”detailDataBound” events of the EJ2 Grid. Please find the below code snippet and Sample documentation links for your reference.  

  

@{  

    var ChildGrid1 = new Syncfusion.EJ2.Grids.Grid()  

    {  

        DataSource = ViewBag.empData,  

        QueryString = "EmployeeID",  

        Created ="created",  

        DataBound="dataBound",  

         . . .  

}  

  

    };  

        }  

  

<ejs-grid id="PublishedGrid" dataSource="ViewBag.data" childGrid="ChildGrid1" detailDataBound="detailDataBound" allowPaging="true" >  

    . . .  

</ejs-grid>  

<script>  

    var val;  

    var flag = 1;  

    function detailDataBound(args) {  

        val = args.data;    

    }  

    function created(args) {  

        flag = 1;  

    }  

    function dataBound(args) {  

        if (flag) {  

            var pre = [];  

  

           // You can handle many unique columns(querystring) in Child Grid 

            pre.push(new ej.data.Predicate('EmployeeID', 'equal', val["EmployeeID"]));  

            pre.push(new ej.data.Predicate('orderid', 'equal', val["OrderID"]));  

            this.query = new ej.data.Query().where(new ej.data.Predicate.and(pre));  

            this.refresh();  

            flag = 0;  

        }  

      

    }  

</script>
