ODataV4 binding with embedded object

[Eugene Kudryavtsev]

Hi,

 

I'm having trouble getting TreeGrid to work with my project requirements.

I'm running WebAssembly 5.0.2 and Syncfusion 18.4.0.35.

This is the code I'm having issues with:

@using Syncfusion.Blazor
@using Syncfusion.Blazor.Data
@using Syncfusion.Blazor.TreeGrid

<SfTreeGrid TValue="E"
            IdMapping="@nameof(E.Id)"
            ParentIdMapping="@nameof(E.ParentId)"
            HasChildMapping="@nameof(E.HasChildren)"
            TreeColumnIndex="1"
            AllowPaging="true">
    <SfDataManager Url="https://app.psam.io/api/reference-data-groups"
                   Adaptor="Adaptors.ODataV4Adaptor" />
    <TreeGridColumns>
        <TreeGridColumn Field="@nameof(E.Id)" IsPrimaryKey="true" />
        <TreeGridColumn Field="@nameof(E.Abbreviation)" />
        <TreeGridColumn Field="@nameof(E.CountDirectChildren)" />
    TreeGridColumns>
SfTreeGrid>

@code {

    public class E
    {
        public DateTime DateTimeCreated { get; set; }
        public DateTime DateTimeLastModified { get; set; }
        public Guid Id { get; set; }
        public Guid? ParentId { get; set; }
        public bool HasChildren { get; set; }
        public int CountDirectChildren { get; set; }
        public string Abbreviation { get; set; }
        public Tp TranslatedProperties { get; set; }
    }

    public class Tp
    {
        public string Name { get; set; }
        public string Information { get; set; }
    }

}

And this is the error that I'm getting in the console, with no data but a spinning animation being shown in the UI.

Please note that commenting out this line :

// public Tp TranslatedProperties { get; set; }

solves the TreeGrid issue, but does not satisfy my requirements. Also, such embedded objects work just fine with other Syncfusion controls such as SfrDropDownList.

I've opened up the corresponding endpoint so that you can verify whether you are getting the same error.

Please let me know when embedded objects will be supported in such scenarios.

Best regards
Eugene

Hi Padmavathy,

Thank you for your quick reply.

1. The code I sent to you is the whole code except for a @page directive at the top.

2. I did start with the Hosted Blazor Web Assembly App template

Hi Eugene,   

 

Thanks for the update.   

 

We have validated the reported issue, but we do not have support for complex binding feature. We already logged feature task for providing “Support for Complex Bindings  with ExpandoObject for the SfTreeGrid control”. Support for this feature will be rolled out to  Volume 4 SP1 release which is expected to be rolled out at the end of January 2020.

Dear Syncfusion Support,

Thank you for your replies.

It's unfortunate that this feature doesn't work as in SfGrid or SfDropDownList and that it won't be implemented until march.

In the meantime, I will flatten my model for this specific use case.

Best regards

Eugene
