When using an AutoComplete in a DataGrid the datamanager is called multiple times and duplicate data is shown.
I am using an AutoComplete inside a DataGrid like this:
<SfGrid DataSource="@Actions" @ref="ActionsGrid" Toolbar="@(new List<string>() { "Add", "Edit", "Delete", "Update", "Cancel" })">
<GridEditSettings AllowAdding="true" AllowDeleting="true" AllowEditing="true"></GridEditSettings>
<GridColumns>
<GridColumn Field=@nameof(ActionRow.Id) HeaderText="ID" Width="120" Visible="false"></GridColumn>
<GridColumn Field=@nameof(ActionRow.DisplayName) HeaderText="Team" Width="150">
<EditTemplate>
<SfAutoComplete TItem="Group" TValue="string" ID="Id" @bind-value="@((context as ActionRow).Team.DisplayName)">
<SfDataManager AdaptorInstance="@typeof(CustomAdaptor)" Adaptor="Adaptors.CustomAdaptor"></SfDataManager>
<AutoCompleteFieldSettings Value="DisplayName"></AutoCompleteFieldSettings>
</SfAutoComplete>
</EditTemplate>
</GridColumn>
</GridColumns>
</SfGrid>
Inside the Custom DataManager I have the following. I am calling _apiService which is an injected data access service.
public override async Task<object> ReadAsync(DataManagerRequest dm, string key = null)
{
IEnumerable<Group> DataSource = new List<Group>();
if (dm.Where != null && dm.Where.Count > 0) //Filtering
{
var search = (string) dm.Where[0].value;
DataSource = await _apiService.GetData(search);
}
Console.WriteLine("Queried...");
return dm.RequiresCounts ? new DataResult() { Result = DataSource, Count = DataSource.Count() } : (object)DataSource;
}
However, when I enter edit mode for a row I see the ReadAsync call is called multiple times and the dropdown that is presented contains duplicates of the data. 
If i type 1 character in the autocomplete ReadAsync is called twice. I have two rows in the grid so could that be related?
I would expect for 1 character that ReadAsync is called once and the dropdown only contains one set of the results.
