Using DataSource property of Grid Column to show DropDown list in editing

[Junaid]

Good day,

I have a GridColumn in which I want to show a simple drop-down list that contains two values i.e. "In progress" and "Completed". I have used the EditType.DropDown property and during editing a drop-down appears as well but it is empty with no text. I have used the DataSource property in GridColumn but the text is not being displayed. How can I display the text dropdown? 

It is to be noted here that I am using WebApiAdaptor with EjsDataManager to display and perform CRUD operations on data. 

<EjsGrid TValue="Projekte" AllowPaging="true" AllowFiltering="true" AllowSorting="true" Toolbar="@(new List() { "Add", "Edit", "Delete", "Cancel", "Update" })">

            <EjsDataManager Url="/Api/Default" Adaptor="Adaptors.WebApiAdaptor">EjsDataManager>

            <GridEditSettings AllowAdding="true" AllowDeleting="true" AllowEditing="true" Mode="EditMode.Normal">GridEditSettings>

            <GridColumns>

                <GridColumn Field=@nameof(Projekte.Id) AllowEditing="false"HeaderText="ID" TextAlign="TextAlign.Right">GridColumn>

                <GridColumn Field=@nameof(Projekte.Status) HeaderText="Status" EditType="EditType.DropDownEdit" TextAlign="TextAlign.Right"

            DataSource="@status"> GridColumn>

            GridColumns>

        EjsGrid>

@code{

    public List<string> status { set; get; }

    protected override void OnInitialized()

    {

        status   = new List<string>{"In Process","Completed"};

    }

}

P.S. I have tried using the Template inside the grid column (as shown here: https://www.syncfusion.com/forums/149233/syncfusion-blazor-binding-drop-down-list-in-grid-column) but it gives me an error.
