SfDataManager ODataV4Adaptor Inheritence

Dear support,

How to specify a cast to  derived entity dynamically (without setting it at the Url parameter) ?





Simple Odata Example:

var flights = await client
    .NavigateTo(x => x.Trips)
    .NavigateTo(x => x.PlanItems)

Hi Vincent,

Greetings from Syncfusion support.

We analyzed your scenario, and we suggest you set the BatchUrl and Url properties of SFDataManager to achieve your requirement. Please refer to the below code snippet.

<SfGrid @ref="Grid1" TValue="Vehicle" AllowSorting="true" AllowFiltering="true" AllowPaging="true" Toolbar="@(new List<string>() { "Cancel", "Update" })">

    <SfDataManager @ref="dm" Url="/Vehicles?$expand=VehicleMake" BatchUrl="/Vehicles" Adaptor="Adaptors.ODataV4Adaptor"></SfDataManager>

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


        <GridColumn Field="@nameof(Vehicle.VehicleId)" IsPrimaryKey="true" Visible="false"></GridColumn>

        <GridColumn Field="@nameof(Vehicle.RegistrationNumber)"></GridColumn>

        <GridColumn Field="VehicleMake.VehicleMakeText"></GridColumn>



Kindly get back to us if you have any further queries.

Dear support,

This workaround is not working, as for expemple, I need to expand a property on the derived object when initializing the grid.

I clearly need a "Cast" functionality so that the data manager only add the cast url block at the end of the default query behaviour.


Actually: https://localhost:7003/v1/TransCategoryBases



Actually: https://localhost:7003/v1/TransCategoryBases (10d2ceb1-f292-49bc-9230-1de352c656b4)

Expected https://localhost:7003/v1/TransCategoryBases(10d2ceb1-f292-49bc-9230-1de352c656b4) /AMI.FinancialTransCategoryModel

and not https://localhost:7003/v1/TransCategoryBases/AMI.FinancialTransCategoryModel (10d2ceb1-f292-49bc-9230-1de352c656b4)

if I cast at the url level like below

<SfDataManager Url="@($"{xxxx}/TransSubCategoryBases/AMI.FinanceTransCategoryModel")" .../>

We have analyzed your query and we suggest you add parameters dynamically by using Add params method. We have discussed this topic in detail in our UG documentation. Kindly refer to the attached document link for your reference.
