I'm trying to show and edit complex object in Grid.

Object is: 
public class WorkoutTaskModel
        public int Id { get; set; }
        public ExerciseModel Exercise { get; set; }
        public int? Approaches { get; set; }
        public int? Repetitions{ get; set; }

 public class ExerciseModel
        public int Id { get; set; }
        public string Name { get; set; }

How to to show Exercise name in Grid, but use dropdown filled with List<ExerciseModel>  in Edit mode?
<EjsGrid DataSource="Workout.WorkoutTasks" ID="Grid" AllowPaging="true" EnableHover="true"  Toolbar="@(new List<string>() { "Add", "Edit", "Delete", "Cancel", "Update"})">
            <GridEditSettings AllowAdding="true" AllowDeleting="true" ShowDeleteConfirmDialog="true" AllowEditing="true" AllowEditOnDblClick="true" Mode="EditMode.Normal">
                <GridColumn Field="Exercise.Name">
                        <EjsDropDownList ID="Exercise" Value="@((context as WorkoutTaskModel).ExerciseId)" DataSource="@ExercisesList" FloatLabelType="FloatLabelType.Always" Placeholder="Exercise">
                            <DropDownListFieldSettings Value="Id" Text="Name"></DropDownListFieldSettings>
                <GridColumn Field="@nameof(WorkoutTaskModel.Approaches)"></GridColumn>
                <GridColumn Field="@nameof(WorkoutTaskModel.Repetitions)"></GridColumn>
                <GridColumn Field="@nameof(WorkoutTaskModel.ExecutionTime)"></GridColumn>
                <GridColumn Field="@nameof(WorkoutTaskModel.ColorCode)"></GridColumn>
                <GridColumn Field="@nameof(WorkoutTaskModel.RestTime)"></GridColumn>
                <GridColumn Field="@nameof(WorkoutTaskModel.ExerciseLoad)"></GridColumn>
                <GridColumn Field="@nameof(WorkoutTaskModel.Order)"></GridColumn>
                <GridColumn Field="@nameof(WorkoutTaskModel.Id)" IsIdentity="true" Visible="false"></GridColumn>

In this case View mode is ok, Name is shown. But in editing mode dropdown not working.

Hi Aleksandrs,  
Thanks for contacting Syncfusion support.  
Query:” How to to show Exercise name in Grid, but use dropdown filled with List<ExerciseModel>  in Edit mode? 
We have achieved your requirement using Column Template feature and Edit Template feature of EjsGrid.  From your query we understand that you want to display a text of complex object in Grid and while editing, you want to render DropDownList with text and value pair.  
Using ColumnTemplate feature we have displayed the Text in GridColumn and using OnActionBegin event, we have saved the changed value into datasource. Refer the below code example. 
<EjsGrid DataSource="@Orders" AllowPaging="true" EnableHover="true" Toolbar="@(new List<string>() { "Add", "Edit", "Delete", "Cancel", "Update"})"> 
    <GridEvents OnActionBegin="OnBegin" TValue="Order"></GridEvents> 
. . . . . . .. .  
        <GridColumn Field=@nameof(Order.OrderID) HeaderText="Order ID" IsPrimaryKey="true" TextAlign="TextAlign.Right" Width="120"></GridColumn> 
        @*Bind integer value to grid COlumn*@ 
        <GridColumn Field="Employee.EmployeeID" HeaderText="Employee Name" Width="150"> 
                    var val = (context as Order).Employee.FirstName;  // display its corresponding  text with column template                   
                <EjsDropDownList @ref="Ddl" Value="@((context as Order).Employee.EmployeeID)" DataSource="@Employees" Placeholder="Exercise"> 
                    <DropDownListFieldSettings Value="EmployeeID" Text="FirstName"></DropDownListFieldSettings> 
. . . . . .  
    EjsDropDownList<int?, EmployeeData> Ddl { get; set; } 
    public List<Order> Orders { get; set; } 
    public static List<EmployeeData> Employees { get; set; } 
    public void OnBegin(ActionEventArgs<Order> Args) 
        //Save the change in datasource on clicking the udpate button  
        if(Args.RequestType == Syncfusion.EJ2.Blazor.Grids.Action.Save) 
            Args.Data.Employee.EmployeeID = Ddl.Value; 
            Args.Data.Employee.FirstName = Employees.Where(f => f.EmployeeID == Ddl.Value).FirstOrDefault().FirstName; 
    protected override void OnInitialized() 
         .. . . ..  . . . 
For your convenience we have prepared a sample which can be downloaded from below  
Refer our UG documentation for your reference 
Please get back to us if you have further queries.
