Child Grid with CRUD & Dropdown

using the childgrid field of new HierarchyGrids in ej2 how can I implement CRUD in the childgrid? also what if i have a dropdownlist as one of the fields in the child grid, how is this done?
In parent Grid, foreign keys are handled like so:  
headertext="Produce Group" 

How can I do this in the Child Grid.

Hi Yoab, 

Greetings from Syncfusion support. 

Based on your query we suspect that you want to know how to enable CRUD configuration for child Grid and set foreignKey column for child Grid. There is no difference to set foreignKey column and enable CRUD operation with child Grid as you given in normal. 

Refer the help documentation. 

Please let us know if you need further assistance on this.

Hello I'm afraid you didn't quite understand me. I am talking about the childgrid using the new specification in the master grid(childGrid="ChildGrid1")
the childgrid is then specified as something like:


    var ChildGrid1 = new Syncfusion.EJ2.Grids.Grid()
        DataSource = @pb.GetAll(),
        QueryString = "PayeesId",

        Columns = new List<Syncfusion.EJ2.Grids.GridColumn> {
        new Syncfusion.EJ2.Grids.GridColumn(){ Field="BanksId", HeaderText="Bank", Width="200" },
        new Syncfusion.EJ2.Grids.GridColumn(){ Field="AccountNo", HeaderText="Account No.", Width="70", TextAlign=Syncfusion.EJ2.Grids.TextAlign.Right }




In this case foreign key in the above child grid cannot be specified as in the mastergrid neither can the CRUD

Hi Yoab, 

Thanks for your clarification. 

As per your suggestion we have created a sample with foreign key column and editing feature in child Grid. Please refer the below code example and sample for more information. 

            var ChildGrid1 = new Syncfusion.EJ2.Grids.Grid() 
                DataSource = ViewBag.empData, 
                QueryString = "EmployeeID", 
                EditSettings = new Syncfusion.EJ2.Grids.GridEditSettings() { AllowAdding = true, AllowEditing = true, AllowDeleting = true }, 
                Toolbar = new List<string>() { "Add", "Edit", "Delete", "Update", "Delete" }, 
                Aggregates = new List<Syncfusion.EJ2.Grids.GridAggregate> { 
            new Syncfusion.EJ2.Grids.GridAggregate() {Columns =col} }, 
                Columns = new List<Syncfusion.EJ2.Grids.GridColumn> { 
new Syncfusion.EJ2.Grids.GridColumn(){ Field="orderid", HeaderText="ID", IsPrimaryKey=true, Width="200" }, 
new Syncfusion.EJ2.Grids.GridColumn(){ Field="id", ForeignKeyField="EmployeeID1", ForeignKeyValue="FullName", DataSource= ViewBag.empData1, HeaderText="Full Name", Width="200" }, 
<ejs-grid id="PublishedGrid" dataSource="ViewBag.data" childGrid="ChildGrid1" allowPaging="true" gridLines="Both"> 
    <e-grid-pagesettings pageSize="10"></e-grid-pagesettings> 
    <e-grid-editSettings allowAdding="false" allowDeleting="false" allowEditing="false" showDeleteConfirmDialog="true" showConfirmDialog="true"></e-grid-editSettings> 
    <e-grid-textwrapsettings wrapMode="Both"></e-grid-textwrapsettings> 
        <e-grid-column field="OrderID" isIdentity="true" isPrimaryKey="true" width="180" textAlign="Right" visible="true"></e-grid-column> 
        <e-grid-column field="EmployeeID" headertext="HReadable" width="150"></e-grid-column>
